CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.

Selec-TracII Transfer Case – If Equipped
Operating Information And Precautions
The Selec-Trac II active on-demand transfer case pro-
vides four positions:
•Two-wheel drive (2WD) high range
•Four-wheel drive Auto (4WD AUTO) high range
•Neutral (N)
•Four-wheel drive (4WD LOW) low range
This transfer case is intended to be driven in either the
two-wheel drive position (2WD) or the four-wheel drive
Auto position (4WD AUTO) for normal street and high-
way conditions such as dry hard-surfaced roads. For added capability when traversing steep grades,
rough terrain, or extremely poor traction surfaces, select
the transfer case 4WD LOW position. This position locks
the front driveshaft and rear driveshaft together and
forces the front and rear wheels to rotate at the same
speed while multiplying engine torque.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in “Starting
and Operating” for further information.
CAUTION!
•The 4WD LOW position is intended for loose or
slippery road surfaces only. Driving in this posi-
tion on dry hard-surfaced roads may cause in-
creased tire wear and damage to the driveline
components.

CAUTION! (Continued)
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD AUTO position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case. Tire rotation
schedule should be followed to balance tire wear.
WARNING!
•You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging
the parking brake. The transfer case NEUTRAL
position disengages both the front driveshaft and
rear driveshaft from the powertrain and it will
allow the vehicle to move despite the transmission
position. The parking brake should always be
applied when the driver is not in the vehicle.
•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.(Continued)

4WD Auto
Four-Wheel Drive Auto High Range – This active on-
demand range makes available optimum traction for a
wide range of conditions, while maximizing driver con-
venience. This position is always in four-wheel drive
mode, with a normal 42% front axle, 58% rear axle torque
split. The system also anticipates and prevents slip by
redirecting torque as necessary, up to 100% to the front or
rear axle, if needed.
4WD Low
Four-Wheel Drive Low Range - This range is for low
speed four-wheel drive. Locks the front driveshaft and
rear driveshaft together forcing the front and rear wheels
to rotate at the same speed. Additional traction and
maximum pulling power for loose or slippery road
surfaces only. Do not exceed 25 mph (40 km/h).N
Neutral - This range disengages both the front driveshaft
and rear driveshaft from the powertrain. To be used for
flat towing behind another vehicle. Refer to “Recreational
Towing” in “Starting and Operating” for further
information.
Transfer Case Position Indicator Lights
The four-wheel drive indicator lights (4WD, 4 LOW) are
located in the instrument cluster. The NEUTRAL indica-
tor light is located on the transfer case switch. If there is
no indicator light on or flashing, the transfer case posi-
tion is two-wheel drive (2WD). If the indicator light is on,
the desired position (4WD AUTO, 4WD LOW, or NEU-
TRAL) has been obtained.
If One Or More Shift Requirements Are Not Met:
•An indicator light will flash.
•The transfer case
will notshift.
342 STARTING AND OPERATING

NOTE:The “SERV 4WD Warning Light” monitors the
electric shift four-wheel drive system. If this light re-
mains on after engine start up, or it illuminates during
driving, it means that the four-wheel drive system is not
functioning properly and that service is required.
Shifting Procedures
NOTE: If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift, the indicator light for the previous position
will remain on, and the newly selected position indicator
light will continue to flash until all the requirements for
the selected position have been met. To retry a shift, move
the transfer case switch back to the original position,
make certain all shift requirements have been met, wait
five seconds, and try the shift again.
2WD To 4WD Auto
Move the transfer case switch to the desired position.
Shifts between 2WD and 4WD Auto can be done with the vehicle stopped or in motion. If the vehicle is stopped,
the ignition switch must be in the ON position with the
engine either OFF or RUNNING. This shift cannot be
completed if the ignition switch is in the ACC position.
2WD Or 4WD Auto To 4WD Low
When shifting into or out of 4WD LOW, some gear noise
may be heard. This noise is normal and is not detrimental
to the vehicle or its occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) using the “Preferred Procedure” or
completely stopped using the “Alternate Procedure.”
Preferred Procedure
1. With the engine RUNNING, slow the vehicle speed to
2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.

HDC control speed. If more speed is desired during HDC
control, the accelerator pedal will increase vehicle speed
in the usual manner. When either the brake or the
accelerator is released, HDC will control the vehicle at the
original set speed.
NOTE:HDC is available on vehicles equipped with the
MP1522 transfer case.
•The transfer case must be in 4WD LOW range to
enable HDC.
•HDC is enabled only when the “Hill Descent Control
Indicator Light” in the instrument cluster is on solid.
•HDC will NOT activate when the automatic transmis-
sion is in PARK.
•HDC will NOT activate on level ground.
•HDC will NOT activate at vehicle speeds above
30 mph (50 km/h). The “Hill Descent” button is located in the lower switch
bank below the climate control.
Enabling HDC
1. Shift the transfer case into 4WD LOW range. Refer to
“Four-Wheel Drive Operation” in “Starting and Operat-
ing” for further information.

In this mode, ESC and TCS are turned off (except for the
“limited slip” feature described in the TCS section) until
the vehicle reaches a speed of 40 mph (64 km/k). At
speeds over 40 mph (64 km/k), the system automatically
switches to “Partial Off” mode, described above. When
the vehicle speed returns to less than 35 mph (56 km/h),
the ESC system will return to “Full Off” mode. The “ESC
Activation/Malfunction Indicator Light” is always illu-
minated when ESC is off. To turn ESC on again, momen-
tarily press the “ESC Off” button. This will restore the
normal “ESC On” mode of operation.
NOTE:
•“Full Off” is the only operating mode for ESC in 4WD
LOW range. The ESC system will be in this mode
whenever the vehicle is started in 4WD LOW range or
the transfer case is shifted into 4WD LOW range.
•The “ESC OFF” message will display and a chime will
sound when the shift lever is moved from any positionto the PARK position and then moved out of the PARK
position. This will occur even if the message was
cleared previously.
WARNING!
With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. “Full Off”
mode is only intended for off-highway or off-road
use.
