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.

1. If any tire pressure has exceeded the low or high
pressure (refer to STARTING AND OPERATING Ð
TIRES AND WHEELS), the TPM system will display a
message in the EVIC and sound a chime. It will then go
into the tire pressure display screen and flash the pres-
sure value of the tire that is low or high. This will be
displayed for the rest of the ignition cycle, or until either
the C/T, MENU, STEP, or RESET button is pressed.
NOTE:This display will return 60 seconds after either
the C/T, MENU, STEP, or RESET button is pressed. If a
tire is low or high, you should correct your tire inflation
pressure as soon as possible and inspect all of your tires.
Refer to STARTING AND OPERATING Ð TIRES AND
WHEELS for more details.
Once the low or high tire pressure message has occurred,
it will continue to blink until the tire pressure is cor-
rected.2. If the spare tire pressure has exceeded the low or high
pressure allowed, the TPM system will display a message
in the EVIC for 60 seconds and sound a chime per every
ignition cycle (5 Tire TPM System Only).
NOTE:This message will return every ignition cycle,
until the tire pressures are corrected.
3. When the vehicle is moving and the EVIC cannot
receive a valid sensor signal from the tire pressure
sensors, the TIRE PRESSURE UNAVAILABLE message
will be displayed for 5 seconds along with a chime. The
display will then shift to the individual tire pressure
display screen and display dashes for the tire or tires that
are affected. Once the TIRE PRESSURE UNAVAILABLE
message has been displayed, and valid sensor signals are
received, the EVIC will display the TIRE PRESSURE
NOW AVAILABLE message for 5 seconds along with a
chime. This is meant to inform you when the TPM system
has returned to it's normal operation. This will occur

INSTRUMENT CLUSTER DESCRIPTION
1. Voltmeter
Indicates available battery voltage and charging
system operation. The lower red zone shows that
the battery charge may be too low to start the engine.
With the engine running, the normal operating range is
between 11 and 15 volts. Prolonged gage readings be-
tween 9-11 (undercharge) or above 15 (overcharge) indi-
cate possible malfunction of the generator, voltage regu-
lator or battery. See your dealer if such signs occur.
2. Turn Signal Indicator Light
The arrows will flash in unison with the exterior
turn signals, when using the multi-function control
lever. When the hazard warning system is activated, both
the indicator lights will flash simultaneously.
3. Tachometer
Indicates the engine speed in revolutions per minute.
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.
4. High Beam Indicator Light
This light shows that the headlights are on high
beam. Pull the multi-function control lever to-
wards the steering wheel to switch the headlights from
high to low beam.
5. Airbag Warning Light
This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If the
bulb does not come on during starting, have it serviced.
If the light stays on or comes on while driving, have the
airbag system checked by an authorized dealer.
6. Speedometer
Indicates vehicle speed.

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.

²When shifting into P (Park), depress the button on the
shift lever and firmly move the lever all the way
forward until it stops.
²Look at the shift indicator window on the console to
ensure it is in the P (Park) position.
²When engaged in P (Park), you will not be able to
move the shifter rearward without depressing the shift
lever button.
CAUTION!
Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK to ON so steering
wheel and shift lever are released. Otherwise, dam-
age to steering column or shifter could result.
RÐReverse
Use this range only after the vehicle has come to a
complete stop.
NÐNeutral
Shift to N (Neutral) when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
Overdrive
For most city and highway driving. The transmis-
sion contains electronically controlled 4th and 5th
gears (Overdrives) and will automatically shift from D
(Drive) to 4th and 5th gears if the following conditions
are present:
²The transmission selector is in D (Drive).
²The O/D OFF switch has not been activated.
182 STARTING AND OPERATING

Rocking the Vehicle
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between ªFirstº and R (Reverse),
while applying slight pressure to the accelerator.
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Racing the engine or
spinning the wheels, due to the frustration of not freeing
the vehicle, may lead to transmission overheating and
failure. Allow the engine to idle with the transmission
selector in N (Neutral) for at least one minute after every
five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during
prolonged efforts to free a stuck vehicle.CAUTION!
When ªrockingº a stuck vehicle by moving between
ªFirstº and R (Reverse), do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
