The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-road.
You should be familiar with the terrain and area before
proceeding. There are many types of surface conditions:
hard-packed dirt, gravel, rocks, grass, sand, mud, snow
and ice. Every surface has a different effect on your
vehicle's steering, handling and traction. Controlling your
vehicle is one of the keys to successful off-road driving, so
always keep a firm grip on the steering wheel and
maintain a good driving posture. Avoid sudden
accelerations, turns or braking. In most cases, there are
no road signs, posted speed limits or signal lights.
Therefore, you will need to use your own good judgment on
what is safe and what is not. When on a trail, you should
always be looking ahead for surface obstacles and
changes in terrain. The key is to plan your future driving
route while remembering what you are currently driving
over.
NOTE:It is recommended that the Stop/Start system and the
Forward Collision Warning (FCW) system (if equipped) be
disabled during off-road use.
When To Use 4L Range
When off-road driving, shift into 4L for additional traction
and control on slippery or difficult terrain, ascending or
descending steep hills, and to increase low speed pulling
power. This range should be limited to extreme situations
such as deep snow, mud, steep inclines, or sand where
additional low speed pulling power is needed. Vehicle
speeds in excess of 25 mph (40 km/h) should be avoided
when in 4L.
Simultaneous Brake And Throttle
Operation
Many off-road driving conditions require the simultaneous
use of the brake and throttle (two-footed driving). When
climbing rocks, logs, or other stepped objects, using light
brake pressure with light throttle will keep the vehicle from
jerking or lurching. This technique is also used when you
need to stop and restart a vehicle on a steep incline.
Driving In Snow, Mud And Sand
SNOW
In heavy snow or for additional control and traction at
slower speeds, shift the transmission into a low gear and
the transfer case into 4L if necessary. Do not shift to a
lower gear than necessary to maintain headway.
Over-revving the engine can spin the wheels and traction
will be lost. If you start to slow to a stop, try turning your
steering wheel no more than a 1/4 turn quickly back and
forth, while still applying throttle. This will allow the tires to
get fresh traction and help maintain your momentum.
MUD
Deep mud creates a great deal of suction around the tires
and is very difficult to get through. You should use DRIVE,
with the transfer case in the 4L position to maintain your
momentum. If you start to slow to a stop, try turning your
steering wheel no more than a 1/4 turn quickly back and
forth for additional traction. Mud holes pose an increased
threat of vehicle damage and getting stuck. They are
normally full of debris from previous vehicles getting
stuck. As a good practice before entering any mud hole,
get out and determine how deep it is, if there are any
hidden obstacles and if the vehicle can be safely
recovered if stuck.
WARNING!
 Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an
off-road situation.
A malfunctioning catalytic converter can reach higher
temperatures than in normal operating conditions.
This can cause a fire if you drive slowly or park over
flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious
injury to the driver, occupants or others.
CAUTION!
Do not use 4L when operating the vehicle on dry
pavement. Driveline hardware damage can result.
WARNING!
CAUTION!
On icy or slippery roads, do not downshift at high engine
RPM or vehicle speeds, because engine braking may
cause skidding and loss of control.

180STARTING AND OPERATING
SAND
Soft sand is very difficult to travel through with full tire
pressure. When crossing soft, sandy spots in a trail,
maintain your vehicle's momentum and do not stop. The
key to driving in soft sand is using the appropriate tire
pressure, accelerating slowly, avoiding abrupt maneuvers
and maintaining the vehicle's momentum. If you are going
to be driving on large soft sandy areas or dunes, reduce
your tire pressure to a minimum of 15 psi (103 kPa) to
allow for a greater tire surface area. Reduced tire pressure
will drastically improve your traction and handling while
driving on the soft sand, but you must return the tires to
normal air pressure before driving on pavement or other
hard surfaces. Be sure you have a way to reinflate the tires
prior to reducing the pressure.
Crossing Obstacles (Rocks And Other
High Points)
While driving off-road, you will encounter many types of
terrain. These varying types of terrain bring different types
of obstacles. Before proceeding, review the path ahead to
determine the correct approach and your ability to safely
recover the vehicle if something goes wrong. Keeping a
firm grip on the steering wheel, bring the vehicle to a
complete stop and then inch the vehicle forward until it
makes contact with the object. Apply the throttle lightly while holding a light brake pressure and ease the vehicle
up and over the object.
USING A SPOTTER
There are many times where it is hard to see the obstacle
or determine the correct path. Determining the correct
path can be extremely difficult when you are confronting
many obstacles. In these cases have someone guide you
over, through, or around the obstacle. Have the person
stand a safe distance in front of you where they can see
the obstacle, watch your tires and undercarriage, and
guide you through.
CROSSING LARGE ROCKS
When approaching large rocks, choose a path which
ensures you drive over the largest of them with your tires.
This will lift your undercarriage over the obstacle. The
tread of the tire is tougher and thicker than the side wall
and is designed to take the abuse. Always look ahead and
make every effort to cross the large rocks with your tires.
CROSSING A RAVINE, GULLY, DITCH,
WASHOUT OR RUT
When crossing a ravine, gully, ditch, washout or a large rut,
the angled approach is the key to maintaining your
vehicle's mobility. Approach these obstacles at a
45-degree angle and let each tire go through the obstacle
independently. You need to use caution when crossing
large obstacles with steep sides. Do not attempt to cross
any large obstacle with steep sides at an angle great
enough to put the vehicle at risk of a rollover. If you get
caught in a rut, dig a small trench to the right or left at a
45-degree angle ahead of the front tires. Use the removed
dirt to fill the rut ahead of the turnout you just created. You
should now be able to drive out following the trench you
just created at a 45-degree angle.
CROSSING LOGS
To cross a log, approach it at a slight angle (approximately
10 to 15 degrees). This allows one front tire to be on top
of the log while the other just starts to climb the log. While
climbing the log, modulate your brake and accelerator to
avoid spinning the log out from under your tires. Then ease
the vehicle off the log using your brakes.
CAUTION!
Reduced tire pressures may cause tire unseating and
total loss of air pressure. To reduce the risk of tire
unseating, while at a reduced tire pressure, reduce your
speed and avoid sharp turns or abrupt maneuvers.
WARNING!
Crossing obstacles can cause abrupt steering system
loading which could cause you to lose control of your
vehicle.
CAUTION!

Never attempt to straddle a rock that is large enough
to strike your axles or undercarriage.
 Never attempt to drive over a rock which is large
enough to contact the door sills.
WARNING!
There is an increased risk of rollover when crossing an
obstacle, at any angle, with steep sides.

182STARTING AND OPERATING
DRIVING ACROSS AN INCLINE
If at all possible, avoid driving across an incline. If it is
necessary, know your vehicle's abilities. Driving across an
incline places more weight on the downhill wheels, which
increases the possibilities of a downhill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible, transverse the incline at an angle
heading slightly up or down.
IF YOU STALL OR BEGIN TO LOSE HEADWAY
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift into
REVERSE. Back slowly down the hill allowing engine
braking to control the descent and apply your brakes, if
necessary, but do not allow the tires to lock.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. Only drive through areas which are designated
and approved. Tread lightly and avoid damage to the
environment. Know your vehicle's abilities and be able to
recover it if something goes wrong. Never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. Shift into
FIRST gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L position
and proceed very slowly with a constant slow speed of {3
to 5 mph (5 to 8 km/h) maximum} and light throttle. Keep
the vehicle moving; do not try to accelerate through the
crossing. After crossing any water higher than the bottom
of the axle differentials, inspect all of the vehicle fluids for
signs of water ingestion.
BEFORE YOU CROSS ANY TYPE OF WATER
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick. You
need to be sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy waters;
check for hidden obstacles. Make sure you will not be
intruding on any wildlife, and you can recover the vehicle
if necessary. The key to a safe crossing is the water depth,
current and bottom conditions. On soft bottoms, the
vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
CROSSING PUDDLES, POOLS, FLOODED
AREAS OR OTHER STANDING WATER
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to entering.
This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
WARNING!
Driving across an incline increases the risk of a rollover,
which may result in severe injury.
WARNING!
If the engine stalls or you lose headway or cannot make
it to the top of a steep hill or grade, never attempt to
turn around. To do so may result in tipping and rolling
the vehicle, which may result in severe injury. Always
back carefully straight down a hill in REVERSE. Never
back down a hill in NEUTRAL using only the vehicle
brakes. Never drive diagonally across a hill, always drive
straight up or down.
CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can
cause permanent damage to engine, driveline or
other vehicle components, and your brakes will be
less effective once wet and/or muddy.
 When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering
as a precaution, and check all fluids afterward.
Driving through water may cause damage that may
not be covered by the New Vehicle Limited Warranty.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the radiator.

246SAFETY
(Continued)
NOTE:ERM is disabled any time the ESC is in “Full Off” mode (if
equipped) Úpage 246.
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to counteract these
conditions. Engine power may also be reduced to help the
vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition. The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the TCS is active. If the
ESC Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
“ESC On” is the normal operating mode for the ESC.
Whenever the vehicle is started, the ESC system will be in
this mode. This mode should be used for most driving
conditions. Alternate ESC modes should only be used for
specific reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The capa-
bilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user's safety or the safety of oth
-
ers.
WARNING!
 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capabil -
ities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
WARNING!

SAFETY257
Service FCW Warning
If the system turns off, and the instrument cluster
displays:
ACC/FCW Unavailable Service Required
 Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
NOTE:The alert warning on the cluster will stay on until the tire is
inflated to the placard pressure.
The tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature decreases, the
tire pressure will decrease. Tire pressure should always be
set based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven for
at least three hours, or driven less than 1 mile (1.6 km)
after a three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also increase
as the vehicle is driven. This is normal and there should be
no adjustment for this increased pressure.
See
Úpage 345 on how to properly inflate the vehicle’s
tires. The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warning
(Tire Pressure Monitoring System Warning Light)
illuminates, you must increase the tire pressure to the
recommended cold placard pressure in order for the
TPMS Warning Light to turn off.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
The system will automatically update and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn on the
TPMS Warning Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold placard
pressure value
Úpage 381.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
CAUTION!

The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip -
ment that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on after -
market wheels, and may contribute to a poor overall
system performance. Customers are encouraged to
use Original Equipment Manufacturer (OEM) wheels
to ensure TPMS feature operation.
 Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealer to have your sensor function
checked.
 After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.

(Continued)
TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
Safety
 Fuel Economy
 Tread Wear
 Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the stability of
the vehicle and can produce a feeling of sluggish response
or over responsiveness in the steering.
NOTE:

Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
 Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal
wear patterns and reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver's side B-pillar or rear edge of the driver's side door. At least once a month:

Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual
judgement when determining proper inflation. Tires
may look properly inflated even when they are
under-inflated.
 Inspect tires for signs of tire wear or visible damage.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pressure is
defined as the tire pressure after the vehicle has not been
driven for at least three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of three hours. The
cold tire inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
WARNING!
 Improperly inflated tires are dangerous and can
cause collisions.
 Underinflation increases tire flexing and can result in
overheating and tire failure.
 Overinflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause
damage that result in tire failure.
 Overinflated or underinflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
 Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
 Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the right
or left.
Always drive with each tire inflated to the recom -
mended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure, always
reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the valve stem.

23_JL_OM_EN_USC_t.book Page 352

SERVICING AND MAINTENANCE353
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or
conditions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle operation.
Refer to an authorized tire dealer or original equipment
vehicle dealer for recommended safe operating speeds,
loading and cold tire inflation pressures.
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
The tire has not been driven on when flat.
 The damage is only on the tread section of your tire
(sidewall damage is not repairable).
 The puncture is no greater than ¼ of an inch (6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical size and
service description (Load Index and Speed Symbol).
Replace the tire pressure sensor as well as it is not
designed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has limited driving capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable. When a Run Flat tire is
changed after being driven in a Run Flat mode 14 psi
(96 kPa) condition, please replace the TPMS sensor as it
is not designed to be reused.
NOTE:TPMS sensor must be replaced after driving the vehicle on
a flat tire condition.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the Run Flat
mode.
See the Tire Pressure Monitoring System section for more
information.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle's wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
For further information
Úpage 302.WARNING!
High speed driving with your vehicle under maximum
load is dangerous. The added strain on your tires could
cause them to fail. You could have a serious collision.
Do not drive a vehicle loaded to the maximum capacity
at continuous speeds above 75 mph (120 km/h).
WARNING!
Combining radial ply tires with other types of tires on
your vehicle will cause your vehicle to handle poorly.
The instability could cause a collision. Always use radial
ply tires in sets of four. Never combine them with other
types of tires.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause tire damage or
failure. A tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph
(48 km/h) for more than 30 seconds continuously
when you are stuck, and do not let anyone near a spin
-
ning wheel, no matter what the speed.8
