GETTING TO KNOW YOUR INSTRUMENT PANEL137
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the Forward Collision
Warning System. Contact an authorized
dealer for service Úpage 291.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning
properly and service is required. Contact
an authorized dealer for service.
Sway Bar Fault Warning Light —
If Equipped
This light will illuminate when there is a
fault in the sway bar disconnect system
Úpage 166.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that the
tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire life and fuel consumption may not be
guaranteed. Should one or more tires be in the condition
previously mentioned, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible and
inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
WARNING!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

STARTING AND OPERATING147
(Continued)
2. Press and hold the brake pedal while pushing
the ENGINE START/STOP button once.
3. If the engine fails to start within 10 seconds, place the ignition in the OFF position, wait
10 to 15 seconds to allow the starter to cool,
then repeat the “Extended Park Starting”
procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
10 minutes, then repeat the procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” procedure and the vehicle
has not experienced an extended park condition
as defined previously, it may be flooded. Push the
accelerator pedal all the way to the floor and hold
it there. Crank the engine for no more than 10
seconds. This should clear any excess fuel in case
the engine is flooded. Leave the ignition key in the
ON/ RUN position, release the accelerator pedal
and repeat the “Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically and will
decrease as the engine warms up.
STARTING THE ENGINE — DIESEL ENGINE
(IF EQUIPPED)
Before starting your vehicle, adjust your seat, both
inside and outside mirrors, and fasten your seat
belts.
The starter is allowed to crank for up to 25-second
intervals. Waiting two minutes between such
intervals will protect the starter from overheating.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a
time. Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 343.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans -
mission into PARK and apply the parking
brake.
Always make sure the keyless ignition node is
in the OFF position, key fob is removed from
the vehicle and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the gear selector.

STARTING AND OPERATING151
NOTE:Under certain conditions the Stop/Start system
may be temporarily disabled and the engine fan
will run after the engine is turned off to protect the
engine. These conditions are under high load and
high temperature conditions.
COOLING SYSTEM TIPS — AUTOMATIC
T
RANSMISSION
To reduce the potential for engine and
transmission overheating in high ambient
temperature conditions, take the following actions:
City Driving — When stopped, shift the transmis -
sion into NEUTRAL (N) and increase engine idle
speed.
Highway Driving — Reduce your speed.
Up Steep Hills — Select a lower transmission
gear.
Air Conditioning — Turn it off temporarily.
NOTE:If the coolant temperature is too high, the A/C will
automatically turn off.
Do Not Operate The Engine With Low Oil
Pressure
If the Low Oil Pressure Warning Light turns on while
driving, stop the vehicle and shut down the engine
as soon as possible. After the vehicle is safely
stopped, restart the engine and monitor the lamp. If the lamp is still illuminated, shut the engine off,
contact an authorized dealer, and do not operate
the vehicle until the cause is corrected. If the lamp
is no longer illuminated, the engine can be
operated, but should be taken to an authorized
dealer as soon as possible for further inspection.
NOTE:Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is
in the engine. The engine oil level must be checked
under the hood.
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the
parts fail. Be on the alert for changes in
performance, sounds, and visual evidence that the
engine requires service. Some important clues are:
Engine misfiring or vibrating severely
Sudden loss of power
Unusual engine noises
Fuel, oil or coolant leaks
Sudden change, outside the normal operating
range, in the engine operating temperature
Excessive smoke
Oil pressure drop
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE (IF EQUIPPED)
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration within
the limits of local traffic laws contributes to a good
break-in. Wide-open throttle acceleration in low
gear can be detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur.
For the recommended viscosity and quality grades
see Ú page 424.
CAUTION!
If oil pressure falls to less than normal readings,
shut the engine off immediately. Failure to do so
could result in immediate and severe engine
damage.

172STARTING AND OPERATING
AUTOSTOP MODE
The Stop/Start feature is enabled after every
normal customer engine start. It will remain in
STOP/START NOT READY until you drive forward
with a vehicle speed greater than 5 mph (8 km/h).
At that time, the system will go into STOP/START
READY and if all other conditions are met, can go
into an STOP/START AUTOSTOP ACTIVE mode.
To Activate The STOP/START AUTOSTOP ACTIVE
Mode, The Following Must Occur:

The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster
Ú
page 121.

Vehicle speed must be less than 2 mph
(3 km/h).
The gear selector must be in the NEUTRAL posi -
tion and the clutch pedal must be fully released. The engine will shut down,
the tachometer will fall
to the Stop/Start position, the STOP/START
AUTOSTOP ACTIVE message will appear, and the
heater/air conditioning (HVAC) air flow will be
reduced.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check
many safety and comfort conditions to see if they
are fulfilled. In following situations the engine will
not stop:
Driver’s seat belt is not buckled
Outside temperature is less than 10°F (–12°C)
or greater than 109°F (43°C)
Actual cabin temperature is significantly
different than temperature set on Auto HVAC
HVAC is set to full defrost mode
Engine has not reached normal operating
temperature
Battery is discharged
When driving in REVERSE
Hood is open
Transfer case is in 4L or N (Neutral)
Driver's seat is not occupied or driver door is
open
Vehicle is at high altitude
The vehicle is on a steep grade
Forward Gear is engaged
Steering angle is beyond threshold
System fault is present
HVAC is set to MAX A/C
It may be possible for the vehicle to be driven
several times without the Stop/Start system going
into a STOP/START READY state under more
extreme conditions of the items listed above.
TO START THE ENGINE WHILE IN
A
UTOSTOP MODE
When the gear selector is in NEUTRAL, the engine
will start when the clutch pedal is pressed (does
not require complete/full pedal press). The vehicle
will go into STOP/START SYSTEM NOT READY
mode until the vehicle speed is greater than 5 mph
(8 km/h).
Conditions that will cause the engine to start
automatically while in STOP/START AUTOSTOP
ACTIVE mode, the engine will start automatically
when:
Actual cabin temperature is significantly
different than temperature set on Auto HVAC
HVAC is set to full defrost mode
Stop/Start Autostop Active time exceeds five
minutes
WARNING!
Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 Volt electrical system.
Serious injury or death could result if you do
not disconnect both batteries. To learn how to
properly disconnect, see an authorized dealer.

23_JT_OM_EN_USC_t.book Page 172

STARTING AND OPERATING209
additional low speed pulling power is needed.
Vehicle speeds in excess of 25 mph (40 km/h)
should be avoided when in 4L range.
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 quarter 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 quarter 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.
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
CAUTION!
Do not use 4L range when operating the vehicle
on dry pavement. Driveline hardware damage
can result.
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.
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.

212STARTING AND OPERATING
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. You should only drive
through areas which are designated and approved.
You should tread lightly and avoid damage to the
environment. You should know your vehicle's
abilities and be able to recover it if something goes wrong. You should 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
(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, you should 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!
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 compo -
nents, 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.
