Interior Lights
Courtesy and dome lights are turned on when the front
doors are opened, when the dimmer control (rotating
wheel on the right side of the switch) is rotated to the
upward detent position, or if equipped, when the UN-
LOCK button is pressed on the key fob. When a door is open and the interior lights are on, rotating the dimmer
control all the way down to the OFF detent will cause all
the interior lights to go out. This is also known as the
 Party
mode because it allows the doors to stay open for
extended periods of time without discharging the vehi-
cle’s battery.
The brightness of the instrument panel lighting can be
regulated by rotating the dimmer control up (brighter) or
down (dimmer). When the headlights are ON you can
supplement the brightness of the odometer, trip odom-
eter, radio and overhead console by rotating the control
up until you hear a click. This feature is termed the
“Parade” mode and is useful when headlights are re-
quired during the day.
Club Cab/Quad Cab models may have an optional
switched dome lamp that may be operated by pressing
the lens.

CAUTION!
Do not leave your vehicle unattended with the
engine running as you would not be able to react to
the temperature indicator if the engine overheats.
NOTE: Engine idle speed will automatically increase to
1000 rpm at elevated coolant temperatures to improve
engine cooling.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
14. Security Light
The light will flash rapidly for approximately 16 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower rate after the alarm is set. The security
light will also come on for about two seconds when the
ignition is first turned ON. 15. Transmission Range Indicator (Automatic
Transmissions Only)
When the gear selector lever is moved, this indicator
shows the automatic transmission gear range selected.
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
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 shows individual trip mileage. To
toggle between the odometer and the trip odometer,
press the Odometer/Trip Odometer Button. To reset the
Trip Odometer, press and hold the button while in trip
mode, until the Trip Odometer resets.

NOTE:There is also an engine hour function. This
indicates the total number of hours the engine has been
running. To display the engine hours perform the follow-
ing: Place the ignition in RUN, but do not start the
engine. With the odometer value displayed, hold the trip
button down for a period of 6 seconds. The odometer will
change to trip value first, then it will display the engine
hour value. The engine hours will be displayed for a
period of 30 seconds until the ignition is turned off or the
engine is started.
17. Check Gages Light This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.

filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure. (See page 391 for more information.)

This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
26. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only) This light indicates that there is excessive trans-
mission 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 light comes on, stop the vehicle and run the engine at idle or
faster, with the transmission in NEUTRAL until the light
goes off.
27. Wait To Start Indicator
The Wait To Start Indicator will illuminate when
the ignition is turned to the run position and the
ambient temperature is below 66 degrees F. Follow
engine starting procedure for proper engine starting and
operating. Wait until the Wait To Start Indicator turns
OFF then start the vehicle.

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have an accident
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
