WARNING!
•
You or others could be injured or killed 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 drive
shaft from the powertrain, and will allow the
vehicle to roll, even if the transmission is in PARK.
The parking brake should always be applied when
the driver is not in the vehicle.
•
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator sol-
idly indicates PARK (P) without blinking. Ensure
that the vehicle is completely stopped, and the
PARK position is properly indicated, before exiting
the vehicle.
This electronically shifted transfer case is designed to
be driven in the two-wheel drive position (2WD) for nor-
mal street and highway conditions on dry, hard sur-
faced roads. Driving the vehicle in two-wheel drive will
have greater fuel economy benefits as the front axle is
not engaged in two-wheel drive.
When additional traction is required, the transfer case
4WD HIGH 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
four-wheel drive control switch.
For specific shifting instructions
page 111.
The 4WD HIGH and 4WD LOW positions are designed
for loose, slippery road surfaces only. Driving in the
4WD HIGH and 4WD LOW positions on dry hard sur-
faced roads may cause increased tire wear and dam-
age to the driveline components.
NOTE:
The transfer case NEUTRAL button is located in the cen-
ter of the four-wheel drive Control Switch and is pushed
by using a ballpoint pen or similar object. The transfer
case NEUTRAL position is to be used for recreational
towing only
page 169.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4WD LOW) are located in the instrument cluster and
indicate the current and desired transfer case selec-
tion. 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 One Or More Of The Following Shift Conditions Are
Not Met:
1. The indicator light for the current position will
remain on.
2. The newly selected position indicator light will con-
tinue 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
page 111.
The SERV 4WD Warning Light monitors the electronic
shift four-wheel drive system. If this light remains on
after engine start-up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the SERV 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 two-
wheel drive or 4WD HIGH 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.
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.
