17. 4WD LOW Mode Indicator — If Equipped
This light alerts the driver that the vehicle is in
the 4WD LOW mode. The front and rear drive-
shafts are mechanically locked together forcing
the front and rear wheels to rotate at the same
speed.
18. Seat Belt Warning Light
When the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulb
check. During the bulb check, if the driver’s seat
belt is unbuckled, a chime will sound. After the bulb
check or when driving, if the driver or front passenger
seat belt remains unbuckled, the Seat Belt Warning Light
will flash or remain on continuously. Refer toOccupant
Restraints/Enhanced Driver Seat Belt Reminder System
(BeltAlert)in Section 2 for more information.19. Cruise Indicator
This indicator lights when the speed control
system is turned ON.
20. Odometer
The odometer shows the total distance the vehicle has
been driven.
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.
21. Shift Lever Indicator
This display indicator shows the automatic transmission
shift lever selection.

failure. Allow the engine to idle with the shift lever in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during pro-
longed efforts to free a stuck vehicle.
CAUTION!
When “rocking” a stuck vehicle by moving between
“First” and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
FOUR-WHEEL DRIVE OPERATION
Quadra-Trac IOperating
Instructions/Precautions — If Equipped
The Quadra-Trac Iis a single-speed (HI range only)
transfer case, which provides convenient full-time four–wheel drive. No driver interaction is required. The Brake
Traction Control System (BTC), which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:The Quadra-Trac Isystem is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in this section.
Quadra-Trac IIOperating
Instructions/Precautions — If Equipped
The Quadra-Trac IItransfer case is fully automatic in the
normal driving 4WD HI mode. The Quadra-Trac II
transfer case provides three mode positions — 4WD HI,
NEUTRAL, and 4WD LOW.
This transfer case is fully automatic in the 4WD HI mode.
STARTING AND OPERATING 307

Page 310 of 519
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. The 4WD LOW position is intended for
loose, slippery road surfaces only. Driving in the 4WD
LOW position on dry hard surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
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:
4WD HI
All roads surfaces such as ice, snow, gravel, sand, and dry
hard pavement.
NEUTRAL
Disengages both the front and rear driveshafts from the
powertrain. To be used for flat towing behind another
vehicle. Refer to “Recreational Towing” in Section 5 of
this manual.
4WD LOW
Low speed four-wheel drive. Locks the front and rear
driveshafts together. Forces the front and rear wheels to
rotate at the same speed. Additional traction and maxi-
mum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
Shifting Procedures
4WDHIto4WDLOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
key ON or engine running, shift the transmission into
NEUTRAL, and raise the transfer case T-handle. The
“4WD LOW” indicator light in the instrument cluster,
will begin to flash and remain on solid when the shift is
complete. Release the T-handle.

NOTE:If shift conditions/interlocks are not met, or a
transfer case motor temperature protection condition
exists, a “CHECK SHIFT PROCEDURES” message will
flash from the EVIC (Electronic Vehicle Information Cen-
ter). Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual.4WD LOW to 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
key ON or engine running, shift the transmission into
NEUTRAL, and raise the transfer case T-handle. The
“4WD LOW” indicator light in the instrument cluster,
will flash and go out when the shift is complete. Release
the T-handle.
NOTE:
•If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“CHECK SHIFT PROCEDURES” message will flash
from the EVIC (Electronic Vehicle Information Center).
Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual.
•Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped, however difficulty may
occur due to the mating clutch teeth not being prop-
erly aligned. Several attempts may be required for
Shifter T-Handle
310 STARTING AND OPERATING

clutch teeth alignment and shift completion to occur.
The preferred method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is moving faster
than 3 mph (5 km/h), the transfer case will not allow
the shift.
NEUTRAL Shift Procedure
1. Key ON, engine off.
2. Vehicle stopped, with foot on brake.
3. Place transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a pen,
etc.) for four seconds until the LED lamp by the switch
starts to blink indicating shift in progress. The lamp will
stop blinking (stay on solid) when the NEUTRAL shift is
complete. A “4WD SYSTEM IN NEUTRAL” message will
display on the EVIC (Electronic Vehicle Information
Center). Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual.5. Repeat Steps 1 to 4 to shift out of NEUTRAL.
NOTE:If shift conditions/interlocks are not met, a
“CHECK SHIFT PROCEDURES” message will flash from
the EVIC (Electronic Vehicle Information Center). Refer
to “Electronic Vehicle Information Center (EVIC)” in
Section 4 of this manual.
