Standing Water — Trailhawk Only
Avoid driving in standing water deeper than 19 inches (48
cm), and reduce speed appropriately to minimize wave
effects. Maximum speed in 19 inches (48 cm) of water is
less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Transfer
Unit and Rear Drive Module) to assure they have not been
contaminated. Contaminated fluids and lubricants (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 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-Wheel
Drive Operation” in “Starting And Operating” for further
information. 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.
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 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
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 brakes. Restart the engine and shift
to REVERSE. 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.
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. Always back straight down a hill in
REVERSE gear carefully. Never back down a hill in
NEUTRAL using only the brake.
308 STARTING AND OPERATING
Page 311 of 516

NOTE:Remember, never drive diagonally across a hill -
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 headway by turning
the front wheels slowly left and right. This may provide a
fresh “bite” into the surface and will usually provide
traction to complete the climb.
Traction Downhill
Shift the transmission into a low gear and the 4WD System
to 4WD LOW range or Select Hill Descent Control if
equipped (refer to Electronic Brake Control System in this
section for further information). 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.
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, particularly on
the chassis, drivetrain components, steering, and sus-
pension. 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.

CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe transmission damage. Damage
from improper towing is not covered under the New
Vehicle Limited Warranty.
Four-Wheel Drive (4WD)
The manufacturer requires towing with all four wheels
OFF the ground. Acceptable methods are to tow the vehicle
on a flatbed, or with one end of the vehicle raised and the
opposite end on a towing dolly.
CAUTION!
•DO NOT tow this vehicle with ANY of its wheels on
the ground. Damage to the drivetrain will result.
•
Front or rear wheel lifts must not be used. Internal
damage to the transmission or power transfer unit will
occur if a front or rear wheel lift is used when towing.
• Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or power
transfer unit damage. Damage from improper towing
is not covered under the New Vehicle Limited War-
ranty.
Emergency Tow Hooks — If Equipped
If your vehicle is equipped with tow hooks, there will be
one in the rear and two mounted on the front of the vehicle.
The rear hook will be located on the driver’s side of the
vehicle.
NOTE: For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of damage
to the vehicle.

The suggested Four Wheel Drive (4WD) Tire rotation
method is the “rearward cross” shown in the following
diagram.CAUTION!
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to
the power transfer unit. Tire rotation schedule should
be followed to balance tire wear.
