to turn this feature on or off. Also, refer to ªWindshield
Wipers and Washersº in this section for more information
NOTE:When your headlights come on during the
daytime, the instrument panel lights will automatically
dim to the lower nighttime intensity. Refer to ªInstru-
ment Panel and Interior Lightsº below for setting the
instrument panel lights to full daytime intensity.
Instrument Panel and Interior Lights
When the multi-function control lever is in the parklight,
headlights, or AUTO position (if equipped), rotating the
center portion of the lever up and down will increase and
decrease the brightness (dimmer control) of the instru-
ment panel lights. Full daytime brightness on all elec-
tronic displays (odometer, overhead console, radio, and
Automatic Climate Control (if equipped) is obtained by
rotating the center portion of the control to the first
detent above the dimmer range. Rotating the control to
the second detent above the dimmer range turns theinterior lights on. Rotating the control to the ªOffº
(extreme bottom) position disables all the interior lights,
even when the doors and liftgate are open. While in the
ªOffº position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights Ð Canada Only
The headlights come on at a low intensity level whenever
the engine is running. The lights remain on until the
ignition switch is turned OFF or the parking brake is
engaged. The headlight switch must be used for normal
night time driving.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned OFF, a chime will sound when the driver's door
is opened.

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.

174 STARTING AND OPERATING

NOTE:Even if the transmission can be reset, it is
recommend that you see your dealer at your earliest
possible convenience. Your dealer has the proper diag-
nostic equipment to determine if the problem could
recur. If the transmission is cannot be reset, dealer service
is required.
Gear Ranges
DO NOT race the engine when shifting from P (Park) or
N (Neutral) position into another gear range.
PÐPark
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never use P
(Park) while the vehicle is in motion. Apply the parking
brake when leaving the vehicle in this range. Always
apply the parking brake first, then place the selector in P
(Park) position.
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
shift lever is locked in the P (Park) position, securing
the vehicle against unwanted movement. Further-
more, you should never leave children unattended
inside a vehicle.
The following indicators should be used to ensure that
you have engaged the transmission shift lever into the P
(Park) position:
STARTING AND OPERATING 181

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

Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position, see the information below:
2WD
Rear Wheel Drive High Range Ð Normal street and
highway driving. Dry hard surfaced roads.
4 PART TIME
Part Time 4 Wheel Drive High Range Ð Locks the
transfer case inter-axle differential. Forces the front and
rear wheels to rotate at the same speed. Additional
traction for loose, slippery road surfaces only.
4 FULL TIME
Full Time 4 Wheel Drive High Range Ð Employs inter-
axle differential. Allows front and rear wheels to rotate at
different speeds. All roads surfaces.

(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move

192 STARTING AND OPERATING

Quadra-DriveTSystem Ð If Equipped
The optional Quadra-DrivetSystem features three
torque transfer couplings. The couplings include Vari-
Lok front and rear axles and Quadra-Trac IIttransfer
case. The optional Vari-Lok axles are fully automatic and
require no driver input to operate. Under normal driving
conditions the units function as standard axles balancing
torque evenly between left and right wheels. With a
traction difference between left and right wheels the
coupling will sense a speed difference. As one wheel
begins to spin faster than the other, torque will automati-
cally transfer from the wheel that has less traction to the
wheel that has traction. While the transfer case and axle
couplings differ in design, their operation is similar.
Follow the Quadra-Trac IIttransfer case shifting infor-
mation, preceding this section, for shifting this system.
VARI-LOK FRONT AND REAR AXLES Ð IF
EQUIPPED
The optional Vari-Lok axle is fully automatic and requires
no driver input to operate. Under normal driving condi-
tions the unit functions as a standard axle balancing
torque evenly between left and right wheels. With a
traction difference between left and right wheels the
coupling will sense a speed difference. As one wheel
begins to spin faster than the other, torque will automati-
cally transfer from the wheel that has less traction to the
wheel that has traction.
PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the ªBrake Warning Lightº in the instru-
ment cluster will light.
