WARNING!
• Do not start or run an engine in a closed garage or confined area.
Exhaust gas contains Carbon Monoxide (CO) which is odorless and
colorless. Carbon Monoxide is poisonous and can cause you or
others to be severely injured or killed when inhaled.
• Keep Key Fob transmittersaway fromchildren. Operation of the
Remote Start System, windows, door locks or other controls could
cause you and others to be severely injured or killed.
THEFT ALARM
To A r m
• Press the Key Fob LOCK button or the power door lock switch while the
door is open.
To Disarm
• Press the Key Fob UNLOCK button or turn the ignition to the ON/RUN
position.
SEAT BELT
• Be sure everyone in your vehicle is in a seat and using a seat belt
properly.
• Position the lap belt across your thighs, below your abdomen. To remove
slack in the lap portion, pull up a bit on the shoulder belt. To loosen the
lap belt if it is too tight, tilt the latch plate and pull on the lap belt. A
snug belt reduces the risk of sliding under the belt in a collision.
• Position the shoulder belt on your chest so that it is comfortable and not
resting on your neck. The retractor will withdraw any slack in the belt.
• A shoulder belt placed behind you will not protect you from injury during
a collision. You are more likely to hit your head in a collision if you do not
wear your shoulder belt. The lap and shoulder belt are meant to be used
together.
• A belt that is too loose will not protect you properly. In a sudden stop
you could move too far forward, increasing the possibility of injury. Wear
your seat belt snugly.
• A frayed or torn belt could rip apart in a collision and leave you with no
protection. Inspect the belt system periodically, checking for cuts, frays,
or loose parts. Damaged parts must be replaced immediately. Do not
disassemble or modify the system. Seat belt assemblies must be
replaced after a collision if they have been damaged (bent retractor, torn
webbing, etc.).
• The seat belts for both front seating positions are equipped with
pretensioning devices that are designed to remove slack from the seat
belt in the event of a collision.
GETTING STARTED
11

13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake.
Shifting Out of NEUTRAL (N)
Use the following procedure to prepare your vehicle for normal usage.
1. Bring the vehicle to a complete stop, leaving it connected to the tow
vehicle.
2. Firmly apply the parking brake.
3. Turn the ignition switch to the ON/RUN position, but do not start the
engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Shift the transfer case lever to the desired position.
NOTE:When shifting out of transfer case NEUTRAL (N), turning the engine
OFF may be required to avoid gear clash.
7. Shift the automatic transmission into PARK, or place manual
transmission in Neutral.
8. Release the brake pedal.
9. Disconnect vehicle from the tow vehicle.
10. Start the engine.
11. Press and hold the brake pedal.
12. Release the parking brake.
13. Shift the transmission into gear, release the brake pedal (and clutch
pedal on manual transmissions), and check that the vehicle operates
normally.
CAUTION!
• It is necessary to follow these steps to be certain that the transfer
case is fully in NEUTRAL (N) before recreational towing to prevent
damage to internal parts.
• Damage to the transmission may occur if the transmission is shifted
into PARK with the transfer case in NEUTRAL (N) and the engine
running. With the transfer case in NEUTRAL (N) ensure that the
engine is OFF prior to shifting the transmission into PARK.
• Front or rear wheel lifts should not be used. Internal damage to the
transmission or transfer case will occur if a front or rear wheel lift is
used when recreational towing.
• Tow only in the forward direction. Towing this vehicle backwards
can cause severe damage to the transfer case.
• Automatic transmissions must be placed in the PARK position for
recreational towing.

of arrival. If you feel you are in an “unsafe situation”, please let us know.
With your consent, we will contact local police or safety authorities.
INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Control (ESC) Activation/Malfunction
Indicator 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 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 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.
WHAT TO DO IN EMERGENCIES
84

- 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 and stop 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.
BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system
malfunction or the parking brake is applied. If the light is on and the
parking brake is not applied, it indicates a possible brake hydraulic
malfunction, brake booster problem or an Anti-Lock Brake System
problem.
• Please have your 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., may illuminate 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, a malfunction 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.

4. Finish tightening the lug nuts. Push down on the wrench while at the
end of the handle for increased leverage. Tighten the lug nuts in a star
pattern until each nut has been tightened twice. The correct tightness of
each lug nut 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 service station.
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to
ensure that all lug nuts are properly seated against the wheel.
CAUTION!
Do not attempt to raise the vehicle by jacking on locations other than
those indicated in the Jacking Instructions for this vehicle.
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.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip
off the jack and fall on you. You could be crushed. Never put 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.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used 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 warnings to help prevent
personal injury or damage to your vehicle:
• Alwayspark on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in
PARK; a manual transmission in REVERSE.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and for lifting this
vehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor
traffic.
