garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned on. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.

Heated Seats Ð If Equipped
This feature heats the driver's and passenger's front
seats. The controls for the heated seats are located on the
instrument panel below the heater/air conditioning con-
trols. After turning on the ignition you can choose from
HI, OFF, or LO heat settings.An indicator on the switch shows which setting has been
selected. To turn off the heated seats, position the switch
in the middle.
60/40 Split Rear Seat
Either side of the rear seat can be folded flat to allow for
extended cargo space and still maintain some rear seating
room.
NOTE:Be sure that the front seats are fully upright and
positioned forward. This will allow the rear seatback to
fold down easily.

Tire Pressure Monitor System Ð If Equipped
The Tire Pressure Monitor (TPM) system uses wireless
technology to monitor tire pressure levels. Sensors,
mounted to each wheel as part of the valve stem transmit
tire pressure readings to a receiver located in the over-
head console.The tire pressure is shown in the Electronic Vehicle
Information Center (EVIC) display. The TPM system
remains active even if it is not displayed in the EVIC.
CAUTION!
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure
gauge while adjusting the pressure in your tires.
There will be a delay between the instant you adjust
the air pressure in a tire and when the system
updates the display.
NOTE:The TPM system can inform you about a low or
high tire pressure condition, but it does not replace
normal tire maintenance.
The TPM system is not intended to provide you with
notification of rapid pressure loss.

either too high or too low. Examine the gages carefully,
and follow the instructions above for each indicated
problem.
NOTE:When the ignition switch is turned to OFF, the
fuel gage, voltmeter, oil pressure, and temperature gages
will not show any readings. When the engine is not
running, turn the ignition switch to ON to obtain accu-
rate readings.
12. Part Time Indicator Light
This light alerts the driver that the vehicle is in
the PART TIME four±wheel drive mode, and
the front and rear driveshafts are mechanically
locked together forcing the front and rear wheels to rotate
at the same speed.
13. Transmission Over Temperature Warning Light
This light indicates that there is excessive transmis-
sion fluid temperature that might occur with severe
usage such as trailer towing or snow plowing. If this lightcomes on, stop the vehicle and run the engine at idle or
faster, with the transmission in N (Neutral) until the light
goes off.
14. Temperature Gage
Indicates engine coolant temperature. Any read-
ing within the normal range indicates that the
cooling system is operating satisfactorily.
The gage pointer will likely indicate a higher temperature
(above center scale) when driving in hot weather, up
mountain grades, or when towing a trailer. It should not
be allowed to exceed the upper limits of the normal
operating range.
If the pointer rises to the 260É (Hot) mark, pull over and
stop the vehicle. Do not turn the engine off. Idle the
vehicle with the air conditioning turned off, until the
pointer drops back into the normal range.

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gage reads high, 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 in
the high range, turn the engine off immediately, and
call for service.
15. Reset Button
Press this button to toggle between the odometer and trip
odometer display. When in the trip odometer mode,
holding the button in resets the trip odometer.
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. There are six digits including leading zeros.
The odometer is tamper-resistant.U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
The trip odometer records distance in miles from when-
ever the ªResetº button is pushed. To switch from the
odometer being displayed to the trip odometer being
displayed, press the ªResetº button.
17. O/D (Overdrive) Off Indicator Light
This light will illuminate when the O/D OFF
button has been selected. The O/D OFF button is
located on the gear shift lever.

21. Low Fuel Warning Light
When the fuel level reaches approximately 1.5 U.S.
Gallons (6L) this light will come on and remain on
until fuel is added. The ªLow Fuel Warning Lightº
may turn on and off again, especially during and after
hard braking, accelerations, or turns. This occurs due to
the shifting of the fuel in the tank.
Your vehicle has a programmable electronic feature that
will sound a chime when the ªLow Fuel Warning Lightº
comes on. See the information on ªOverhead Console Ð
Customer Programmable Featuresº in Section 3 to turn
this feature on.
22. Fog Light Indicator Light
This light shows when the fog lamps are on.23. Brake Warning Light
The red BRAKE warning light will come on when
the ignition is first turned on, and stay on briefly
as a bulb check. If the bulb does not come on
during starting, have the bulb repaired promptly. If the
light stays on longer, it may be an indication that the
parking brake has not been released.
If the light remains on when the parking brake is off, it
indicates a possible brake hydraulic system malfunction
or low fluid level. In this case, the light will remain on
until the cause is corrected. If a brake malfunction is
indicated, immediate repair is necessary and continued
operation of the vehicle in this condition is dangerous.
