TRAILER HITCH RECEIVER COVER
R
EMOVAL — IF EQUIPPED
Your vehicle may be equipped with a trailer hitch
receiver cover, this must be removed to access the
trailer hitch receiver. This cover is located at the
bottom center of the rear fascia/bumper.

1. Turn the two locking retainers located at the
bottom of the hitch receiver cover a quarter
turn counterclockwise and pull bottom of the
hitch receiver cover outward (towards you).

2. Pull the bottom of the cover outward (towards you) then downwards to disengage the tabs
located at the top of the hitch receiver cover to
remove.

Hitch Receiver Cover
To reinstall the cover after towing repeat the
procedure in reverse order.NOTE:Be sure to engage all tabs of the hitch receiver
cover in the fascia/bumper prior to installation.
TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your fascia/bumper or trailer hitch.

Weight Distribution
Consider the following items when computing the
weight on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or equip
-
ment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the trailer
adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options
must be considered as part of the total load on
your vehicle. Refer to the Tire And Loading Infor -
mation Placard for the maximum combined weight
of occupants and cargo for your vehicle.
1 — Hitch Receiver Cover
2 — Locking Retainers
WARNING!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the rear
can cause the trailer to sway severely side to
side which will cause loss of control of the
vehicle and trailer. Failure to load trailers heavier
in front is the cause of many trailer collisions.

TOWING REQUIREMENTS
To promote proper break-in of the new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the Scheduled
Servicing Ú
page 330. When towing a trailer,
never exceed the GAWR or GCWR ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when
towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 374.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.

When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or
damage to brakes, axle, engine, transmission,
steering, suspension, chassis structure or tires.

Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the hook retainers of the vehicle
hitch. Cross the chains under the trailer
tongue and allow enough slack for turning
corners.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK (P). For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL (N). Always, block or "chock" the
trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
WARNING!
GAWR
Tongue weight rating for the trailer hitch
utilized
WARNING!

23_WL_OM_EN_USC_t.book Page 192

198STARTING AND OPERATING
If the vehicle is equipped with Quadra-Lift
air suspension, the engine should be
started and left running for a minimum of
60 seconds (with all the doors closed) at
least once every 24 hours. This process
allows the air suspension to adjust the
vehicle’s ride height to compensate for
temperature effects.
Engaging/disengaging of the Electric Park
Brake requires the ignition to be in the ON/
RUN position.
If shift conditions/interlocks are not met, a

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.

23_WL_OM_EN_USC_t.book Page 200

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.
