200STARTING AND OPERATING
OFF-ROAD DRIVING TIPS
Quadra-Lift — If Equipped
When off-roading, it is recommended that the
lowest useable vehicle height that will clear the
current obstacle or terrain be selected. The vehicle
height should then be raised as required by the
changes in terrain.
The Selec-Terrain switch will automatically change
the vehicle to the optimized height based on the
Selec-Terrain switch position. The vehicle height
can be changed from the default height for each
Selec-Terrain mode by normal use of the air
suspension switches Úpage 131.
When To Use 4WD LOW Range —
If Equipped
When off-road driving, shift to 4WD LOW for
additional traction. This range should be limited to
extreme situations such as deep snow, mud, 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 4WD LOW
range.
Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that
must be considered before entering the water.
NOTE:Your vehicle is capable of water fording in up to
24 inches (61 cm) with air suspension or
21 inches (53 cm) without air suspension, of water
while crossing small rivers or streams. To maintain
optimal performance of your vehicle's heating and
ventilation system it is recommended to switch the
system into recirculation mode during water
fording. Be sure to avoid lowering the vehicle in
water, ensure that the easy exit entry setting is
turned off in Uconnect settings. Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
If you must drive through water, try to determine
the depth and the bottom condition (and location
of any obstacles) prior to entering. Proceed with
caution and maintain a steady controlled speed
less than 5 mph (8 km/h) in deep water to
minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off), avoid crossing until the water level
recedes and/or the flow rate is reduced. If you
must cross flowing water avoid depths in excess of
9 inches (23 cm). The flowing water can erode the
streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
WARNING!
Do not drive in 4WD LOW range on dry
pavement; driveline damage may result. 4WD
LOW range locks front and rear drivelines
together and does not allow for differential
action between the front to rear driveshafts.
Driving in 4WD LOW on pavement will cause
driveline binding; use only on wet or slippery
surfaces.
CAUTION!
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.

STARTING AND OPERATING201
Standing Water
Avoid driving in standing water deeper than
24 inches (61 cm) with air suspension or
21 inches (53 cm) without air suspension, and
reduce speed appropriately to minimize wave
effects. Maximum speed is 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil,
transmission oil, axle, transfer case) to ensure the
fluids have not been contaminated. Contaminated
fluid (milky, foamy in appearance) should be
flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary Ú page 131. Only
shift into a lower gear to maintain forward motion.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission
to a lower gear and shift the transfer case to 4WD
LOW. Use FIRST gear and 4WD LOW for very steep
hills.
If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to
a stop and immediately apply the brakes. Restart
the engine, and shift into REVERSE (R). Back slowly
down the hill, allowing the compression braking of
the engine to help regulate your speed. If the
brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires. Remember, never drive diagonally across a hill.
Always drive straight up or down.
If the wheels start to slip as you approach the crest
of a hill, ease off the accelerator and maintain
forward motion by turning the front wheels slowly.
This may provide a fresh “bite” into the surface and
will usually provide traction to complete the climb.
Traction Downhill
When descending mountains or hills, use Hill
Descent Control or Selec-Speed Control to avoid
repeated heavy braking.
If not equipped with Hill Descent Control or
Selec-Speed Control use the following procedure:
Shift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the vehicle
go slowly down the hill with all four wheels turning
against engine compression drag. This will permit
you to control the vehicle speed and direction.
When descending mountains or hills, repeated
braking can cause brake fade with loss of braking
control. Avoid repeated heavy braking by
downshifting the transmission whenever possible.
WARNING!
If the engine stalls, you lose forward motion, 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. Always
back carefully straight down a hill in REVERSE
gear. Never back down a hill in NEUTRAL using
only the brake.

202STARTING AND OPERATING
After Driving Off-Road
Off-road operation puts more stress on your
vehicle than does most on-road driving. After going
off-road, it is always a good idea to check for
damage. That way you can get any problems taken
care of right away and have your vehicle ready
when you need it.
Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
Inspect the radiator for mud and debris and
clean as required.
Check threaded fasteners for looseness, partic -
ularly on the chassis, drivetrain components,
steering, and suspension. Retighten them, if
required, and torque to the values specified in
the Service Manual.
Check for accumulations of plants or brush.
These things could be a fire hazard. They might
hide damage to fuel lines, brake hoses, axle
pinion seals, and propeller shafts.
After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan,
brake rotors, wheels, brake linings, and axle
yokes inspected and cleaned as soon as
possible.
If you experience unusual vibration after driving
in mud, slush or similar conditions, check the
wheels for impacted material. Impacted mate -
rial can cause a wheel imbalance and freeing
the wheels of it will correct the situation.
WARNING!
Abrasive material in any part of the brakes may
cause excessive wear or unpredictable braking.
You might not have full braking power when you
need it to prevent a collision. If you have been
operating your vehicle in dirty conditions, get
your brakes checked and cleaned as necessary.

RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being
on in your vehicle can cause erratic or noisy
performance from your radio. This condition may
be lessened or eliminated by repositioning the
mobile phone within the vehicle. This condition is
not harmful to the radio. If your radio performance
does not satisfactorily improve from repositioning the mobile phone, it is recommended that the
volume be turned down or off during mobile phone
operation when not using the Uconnect system.

ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This 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.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button and the ESC OFF Indicator
Light will illuminate. To turn the ESC on again,
momentarily push the ESC OFF button and the ESC
OFF Indicator Light will turn off.
NOTE:For vehicles with multiple partial ESC modes, the
push and release of the button will toggle the ESC
modes. Multiple attempts may be required to
return to "ESC On" mode.
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator
Light in the instrument cluster will come
on when the ignition is placed in the ON/
RUN mode. It should go out with the
engine running. If the ESC Activation/Malfunction
Indicator Light comes on continuously with the
engine running, a malfunction has been detected
in the ESC system. If this light remains on after
several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized dealer
as soon as possible to have the problem
diagnosed and corrected.
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 exces -
sive speed in turns, driving on very slippery
surfaces, or hydroplaning. 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 capabilities 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 characteristics 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 perfor -
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!
When in “Partial Off” mode, the TCS function -
ality of ESC (except for the limited slip feature
described in the TCS section) has been
disabled and the ESC OFF Indicator Light will
be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.
