WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep key fobs away from children. Operation of the
Remote Start System, windows, door locks or other
controls could cause serious injury or death.
Remote Start Abort Message On The Instrument
Cluster Display
The following messages will display in the instrument
cluster display if the vehicle fails to remote start or exits
remote start prematurely:
• Remote Start Aborted — Door Open
• Remote Start Aborted — Hood Open
• Remote Start Aborted — Fuel Low
• Remote Start Aborted — Liftgate Open
• Remote Start Disabled — Start Vehicle To Reset
• Remote Start Aborted — Too Cold
• Remote Start Aborted — Time Expired The message will stay active until the ignition is turned to
the ON/RUN position.
To Enter Remote Start Mode
Push and release the remote start button on the key fob
twice within five seconds. The vehicle doors will lock, the
parking lights will flash, and the horn will chirp twice (if
programmed). Then, the engine will start, and the vehicle
will remain in the Remote Start mode for a 15-minute cycle.
NOTE:
•
If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during
Remote Start mode.
• For security, power window and power sunroof opera-
tion (if equipped) are disabled when the vehicle is in the
Remote Start mode.
• The engine can be started two consecutive times with
the key fob. However, the ignition must be cycled by
pushing the START/STOP button twice (or the ignition
switch must be cycled to the ON/RUN position) before
you can repeat the start sequence for a third cycle.
30 GETTING TO KNOW YOUR VEHICLE

(RPM x 1000).
2. Instrument Cluster Display •
The instrument cluster display features a driver-
interactive display. Refer to “Instrument Cluster Dis-
play” within this section for further information.
3. Speedometer•Indicates vehicle speed.
4. Fuel Gauge •The fuel gauge shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN mode.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
an authorized dealer for service as soon as possible.

Carefully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine compart-
ment and fuel tank before resetting the system and starting
the engine.
Maintaining Your Air Bag System

WARNING!(Continued)
•If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
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 the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, or brake fluid leaks are
suspected. The cause should be located and corrected
immediately.
236 SAFETY

2. Open the fuel filler door, and remove the fuel filler cap.
NOTE:
•In certain cold conditions, ice may prevent the fuel door
from opening. If this occurs, lightly push on the fuel
door to break the ice buildup and re-release the fuel door
using the inside release button. Do not pry on the door.
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the gas cap about one quarter turn until you
hear one click. This is an indication that the cap is
properly tightened. •
If the gas cap is not tightened properly, the Malfunction
Indicator Light (MIL) will come on. Be sure the gas cap
is tightened every time the vehicle is refueled.

WARNING!(Continued)
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.
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 may 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 Safety Featuresin the “Safety” section
for further information). Let the vehicle go slowly down
the hill with all four wheels turning against engine com-
pression 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.
•
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.

STARTING AND OPERATING 367

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
• Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE: Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you. In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
•
Do not interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
vehicle.
• Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
