STARTING AND OPERATING
will have greater fuel economy benefits as the front
axle is not engaged in 2WD.
When additional traction is required, the transfer
case 4WD LOCK and 4WD LOW positions can be
used to maximize torque to the front driveshaft,
forcing the front and rear wheels to rotate at the
same speed. This is accomplished by pushing the
desired position on the 4WD control switch.
Refer to "Shifting Procedure" in this section for
specific shifting instructions.
The 4WD LOCK and 4WD LOW positions are
designed for loose, slippery road surfaces only.
Driving in the 4WD LOCK and 4WD LOW positions
on dry, hard surfaced roads may cause increased
tire wear and damage to the driveline components.
NOTE:
The transfer case NEUTRAL button is located in the
center of the 4WD Control Switch and is pushed by
using a ballpoint pen or similar object. The transfer
case NEUTRAL position is to be used for recre-
ational towing only. Refer to "Recreational Towing"
in this chapter for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD
and 4LOW) are located in the instrument cluster
and indicate the current and desired transfer case
selection. When you select a different transfer
case position, the indicator lights will do the
following:
If all of the following shift conditions are met:
1. The current position indicator light will turn
OFF.
2. The selected position indicator light will flash
until the transfer case completes the shift.
3. When the shift is complete, the indicator light
for the selected position will stop flashing and
remain ON.
If shift conditions are not met, one or more of the
following events may occur:
1. The indicator light for the current position will
remain ON.
2. The newly selected position indicator light will
continue to flash.
3. The transfer case will not shift.
NOTE:
Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met. To retry the
selection, push the current position, wait five
seconds, and retry selection. To find the shift
requirements, refer to the "Shifting Procedure" for
your transfer case, located in this section.
The "SVC 4WD Warning Light" monitors the
electronically shifted transfer case. If this light
remains on after engine start up or illuminates
during driving, it means that the four-wheel drive
system is not functioning properly and that service
is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the "SVC 4WD Warning Light"
is illuminated. Not engaging the parking brake
may allow the vehicle to roll which may cause
personal injury or death.
NOTE:
Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD, 4WD or 4WD LOCK positions 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 in
tire size can cause damage to the drivetrain.
