Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.
88 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Tire Pressure Monitoring Indicator Light
Yellow TelltaleLight What It Means
Tire Pressure Monitoring Indicator 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 duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the indica-
tions corresponding to each tire in sequence.
IMPORTANT: Do not continue driving with one or more
flat tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. Repair im-
mediately using the dedicated tire repair kit and contact
your authorized dealership as soon as possible.
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 Tire Pressure Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. 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 under-inflated
tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping ability.
248 UNDERSTANDING YOUR INSTRUMENT PANEL
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation 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 continu-
ously 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 re-
placement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing oneor 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.
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.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealership to have your sensor function checked.4

STARTING AND OPERATING 377
NOTE:Before retrying a selection, make certain that all the
necessary requirements for selecting a new transfer case
position have been met. To retry the selection, turn the
control knob back to the current position, wait five sec-
onds, and retry selection. To find the shift requirements,
refer to the Shifting Procedure for your transfer case,
located in this section of the owner’s manual.
The “SERV AWD” Warning Light monitors the electronic
shift all-wheel drive system. If this light remains on after
engine start up or illuminates during driving, it means that
the all-wheel drive system is not functioning properly and
that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SERV AWD Warning Light” is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE: Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause damage to
driveline components. When operating your vehicle in LOW RANGE, the engine
speed is approximately three times that of the AWD AUTO
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of all-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 transfer
case.
Because all-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds.
Do not go faster than road conditions permit.
For additional information on the appropriate use of each
transfer case mode position, see the information below:
AWD Auto
All-Wheel Drive Auto Range – This range sends power to
the rear wheels. The all-wheel drive system will be auto-
matically engaged when the vehicle senses a loss of trac-
tion. Additional traction for varying road conditions.
LOW Range
All-Wheel Drive Low Range – This range provides low
speed all-wheel drive. Locks the front and rear driveshafts
together forcing the front and rear wheels to rotate at the
5
STARTING AND OPERATING 397
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, 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.
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
Shift the transmission into a low gear, and the transfer case
into 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.
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.
