WARNING!
In a collision, you and your passengers can suffer much greater injuries if you are
not buckled up properly. You can strike the interior of your vehicle or other
passengers, or you can be thrown out of the vehicle. Always be sure you and
others in your vehicle are buckled up properly.
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) — AIRBAGS
• This vehicle has Advanced Front Airbags for both the driver and right frontpassenger as a supplement to the seat belt restraint system. The Advanced Front
Airbags will not deploy in every type of collision.
• Advanced Front Airbags are designed to provide additional protection by supplementing the seat belts in certain frontal collisions depending on the severity
and type of collision. Advanced Front Airbags are not expected to reduce the risk of
injury in rear, side, or rollover collisions.
• This vehicle may be equipped with Supplemental Seat-Mounted Side Airbags to provide enhanced protection to help protect an occupant during a side impact.
• If the Airbag Warning Light
is not on during starting, stays on, or turns on while
driving, have the vehicle serviced by an authorized service center immediately.
• Refer to the Owner's Manual on the DVD for further details regarding the Supplemental Restraint System (SRS).
WARNING!
• Relying on the airbags alone could lead to more severe injuries in a collision.The airbags work with your seat belt to restrain you properly. In some
collisions, the airbags won't deploy at all. Always wear your seat belts even
though you have airbags.
• Being too close to the steering wheel or instrument panel during Advanced Front Airbag deployment could cause serious injury, including death. Airbags
need room to inflate. Sit back, comfortably extending your arms to reach the
steering wheel or instrument panel.
• Supplemental Seat-Mounted Side Airbags need room to inflate. Do not lean against the door or window. Sit upright in the center of the seat.
• Being too close to the Seat-Mounted Side Airbag during deployment could cause you to be severely injured or killed.
• Do not drive your vehicle after the airbags have deployed. If you are involved in another collision, the airbags will not be in place to protect you.
• After any collision, the vehicle should be taken to an authorized dealer immediately.
GETTING STARTED
10

OVERDRIVE OFF SWITCH
• Overdrive can be locked out bypressing the O/D OFF switch located
on the center console. An indicator
light in the instrument cluster will
illuminate to show that the switch has
been activated. Pressing the switch a
second time restores the Overdrive
function.
• When frequent transmission shifting occurs while using Overdrive, such as
when operating the vehicle under
heavy load conditions (for example, in
hilly terrain, strong head winds, or
trailer towing), turning off overdrive will
improve performance and extend
transmission life by reducing
excessive shifting and heat buildup.
RECREATIONAL TOWING
(BEHIND MOTORHOME)
Towing - Two-Wheel Drive
Models
• Recreational towing with all fourwheels on the ground is allowed
ONLY if the rear driveshaft is
removed. See your authorized dealer
or refer to the Service Manual. Towing
with the rear wheels on the ground
while the driveshaft is connected can
result in severe transmission damage. • The parking brake must be firmly
engaged and the wheels chocked
during driveshaft removal and
installation. The parking brake must
remain engaged unless the vehicle is
securely and properly connected to
the tow vehicle, or the driveshaft is
completely reinstalled. See your
authorized dealer for proper driveshaft
removal and reinstallation procedures,
including flange orientation/alignment,
use of thread-locking compound,
proper bolt torque specifications, etc.
Towing - Four-Wheel Drive
Models
NOTE: The transfer case must be shifted
into N (Neutral), automatic transmission

INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Control (ESC) Activation/MalfunctionIndicator Light
• 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), we recommend you
drive to the nearest service center and have the vehicle serviced immediately.
• The “ESC Activation/Malfunction Indicator Light” starts to flash as soon as the tires lose traction and the ESC system becomes active. If the light begins to flash during
acceleration, ease up on the accelerator and apply as little throttle as possible. Be
sure to adapt your speed and driving to the prevailing road conditions. The light also
flashes when TCS is active. To improve the vehicle's traction when starting off in
deep snow, sand or gravel, it may be desirable to switch the ESC system to Partial
Off mode by momentarily pressing the ESC Off
switch.
- Tire Pressure Monitoring System (TPMS) Light
• Each tire, including the spare (if provided), should be checked monthly, when coldand 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 illuminates 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.
• IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE,
ADJUST THE AIR PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE
SHOWN ON THE VEHICLE PLACARD OR TIRE INFLATION PRESSURE
LABEL LOCATED ON THE DRIVER'S DOOR. NOTE: AFTER INFLATION, THE
VEHICLE MAY NEED TO BE DRIVEN FOR 20 MINUTES BEFORE THE
FLASHING LIGHT WILL TURN OFF.
WHAT TO DO IN EMERGENCIES
54

• Please note that the TPMS is not a substitute for proper tire maintenance, and it isthe driver’s responsibility to maintain 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 continuously
illuminated. This sequence will continue each time the vehicle is restarted 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.
CAUTION!
The TPMS has been optimized for the original equipment 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 equipment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not use tire sealant from a
can, or balance beads if your vehicle is equipped with a TPMS, as damage to the
sensors may result.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull over andstop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned
by steam or boiling coolant. You may want to call an authorized service center for
service if your vehicle overheats.

Anti-Lock Brake System problem.
• We recommend you drive to the nearest service center and have the vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake
system may have failed. It will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., mayilluminate the MIL after engine start. The vehicle should be serviced if the light stays
on through several typical driving cycles. In most situations, the vehicle will drive
normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. We
recommend you do not operate the vehicle. Have the vehicle serviced immediately.
- Electronic Stability Control OFF Warning Light
• If the ESC OFF warning light comes on continuously with the engine running, amalfunction has been detected.
• 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), we recommend
you drive to the nearest service center and have the vehicle serviced immediately.
- Charging System Light
• This light shows the status of the electrical charging system. If the charging systemlight remains on, it means that the vehicle is experiencing a problem with the
charging system.
• We recommend you do not continue driving if the charging system light is on. Have the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on while driving, stop thevehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
• We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.

- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving, werecommend you drive to the nearest service center and have the vehicle serviced
immediately.
- Electronic Throttle Control (ETC) Light
• This light informs you of a problem with the Electronic Throttle Control (ETC) system.
• If a problem is detected, the light will come on while the engine is running. Cycle theignition when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
• If the light remains lit with the engine running, your vehicle will usually be drivable; however, see an authorized service center immediately. If the light is flashing when
the engine is running, immediate service is required and you may experience
reduced performance, an elevated/rough idle or engine stall and your vehicle may
require towing.
- Airbag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, have thevehicle serviced by an authorized service center immediately.
Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as gASCAP) appears, tighten the gas cap until a“clicking” sound is heard.
• Press the odometer reset button to turn the message off.
• If the message continues to appear for more than three days after tightening the gas cap, see your authorized service center.
Oil Change IndicatorMessage
• If an “oil change” message (shown as CHAngE OIL) appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
HOTOIL – Transmission Temperature Warning Message
• The HOTOIL cluster message will appear in the odometer accompanied with a chime to indicate that there is excessive transmission fluid temperature that might
occur with severe usage such as trailer towing.
• It may also occur when operating the vehicle in a high torque converter slip condition, such as 4-wheel-drive operation (e.g., snow plowing, off-road operation).
• If this HOTOIL message turns on, stop the vehicle and run the engine at idle or faster, with the transmission in NEUTRAL until the message turns off.
WHAT TO DO IN EMERGENCIES
57

CAUTION!
Continuous driving with the Transmission Temperature HOTOIL Warning
message illuminated will eventually cause severe transmission damage and
transmission failure.
WARNING!
Continued operation with the Transmission Temperature HOTOIL Warning
message illuminated could cause the fluid to boil over, come into contact with the
hot engine or exhaust components causing a fire that may result in personal
injury.
IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating bytaking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into NEUTRAL, but do not
increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending overheat
condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the Temperature Control to maximum heat, the Mode Control to floor and the Fan Control to high. This allows the heater core to act as a supplement to the
radiator and aids in removing heat from the engine cooling system.
• If the temperature reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately and call for service.
WHAT TO DO IN EMERGENCIES

• Raise the vehicle by turning the jackscrew clockwise. Raise the vehicle only
until the tire just clears the surface and
enough clearance is obtained to install
the spare tire.
• Remove the lug nuts and wheel.
• Position the spare wheel/tire on the vehicle and install the lug nuts with the
cone-shaped end toward the wheel.
Lightly tighten the lug nuts clockwise.
To avoid the risk of forcing the vehicle
off the jack, do not tighten the nuts fully
until the vehicle has been lowered.
• Lower the vehicle by turning the jack screw counterclockwise, and remove
the jack and wheel blocks.
• Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each one has been tightened twice. The
correct wheel nut tightness is 95 ft lbs (130 N•m). If in doubt about the correct
tightness, have them checked with a torque wrench by your authorized dealer or at
a service station.
• Secure the tire, jack, and tools in their proper locations.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid the danger of being hit when
operating the jack or changing the wheel.
• Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body
under a vehicle that is on a jack. If you need to get under a raised vehicle, take
it to a service center where it can be raised on a lift.
• The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be
jacked on a firm, level surface only. Avoid ice or slippery areas.
• Carefully follow these tire changing procedures to help prevent personal injury or damage to your vehicle: Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the vehicle.
• Raising the vehicle higher than necessary can make the vehicle less stable and could cause it to slip off the jack and hurt someone near it. Raise the vehicle
only enough to remove the tire.
• A loose tire or jack, thrown forward in a collision or hard stop, could endanger the occupants of the vehicle. Always stow the jack parts and the spare tire in
the places provided.
