STARTING AND OPERATING201
For additional information on the appropriate
use of each transfer case mode position, see
the information below:
AWD Auto
All-Wheel Drive Auto Range – This range sends
power to the rear wheels. The all-wheel drive
system will be automatically engaged when the
vehicle senses a loss of traction. Additional
traction for varying road conditions.
LOW Range
All-Wheel Drive Low Range – This range
provides low speed all-wheel drive. Locks the
front and rear driveshafts together forcing the
front and rear wheels to rotate at the same
speed. Additional traction and maximum pulling
power for loose, slippery road surfaces only. Do
not exceed 25 mph (40 km/h).
NEUTRAL (N)
This range disengages both the front and rear
driveshafts from the powertrain. To be used for
flat towing behind another vehicle. Refer to
“Recreational Towing” in this chapter for further
information.
SHIFTING PROCEDURE
NOTE:
If any of the requirements to select a new
transfer case position have not been met, the
transfer case will not shift. The position indi -
cator 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: return the control switch back
to the original position, make certain all shift
requirements have been met, wait five
seconds and try the shift again.
If all the requirements to select a new
transfer case position have been met, the
current position indicator light will turn off,
the selected position indicator light will flash
until the transfer case completes the shift.
When the shift is complete, the position indi
-
cator light for the selected position will stop
flashing and remain on.
AWD Auto To Low Range
NOTE:
When shifting into or out of LOW RANGE some
gear noise may be heard. This noise is normal
and is not detrimental to the vehicle or occu -
pants.
Shifting can be performed with the vehicle
rolling 2 to 3 mph (3 to 5 km/h) or completely
stopped. Use either of the following procedures:
WARNING!
You or others could be injured or killed 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 and rear drive shafts 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.

202STARTING AND OPERATING
Preferred Procedure
1. With the engine running, slow the vehicle
to 2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the AWD control switch to the desired position.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear.
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the ignition in ON/RUN position and engine running, shift the transmission to
NEUTRAL.
3. Rotate the AWD control switch to the desired position.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear. NOTE:
If steps 1 or 2 of either the Preferred or Alter
-
nate Procedure are not satisfied prior to
attempting the shift or if they no longer are
being met while the shift attempt is in
process, the desired position indicator light
will flash continuously while the original posi -
tion indicator light is on, until all require -
ments have been met.
The ignition switch must be in the ON/RUN
position for a shift to take place and for the
position indicator lights to be operable. If the
ignition switch is not in the ON/RUN position,
then the shift will not take place and no posi -
tion indicator lights will be on or flashing.
NEUTRAL Shift Procedure
For information regarding the transfer case
NEUTRAL (N) shift procedure, refer to “Shifting
Into NEUTRAL (N)” in “Recreational Towing” in
this chapter.
FUEL SAVER TECHNOLOGY 5.7L/6.4L ONLY

252STARTING AND OPERATING
Automatic Transmission
Select the DRIVE (D) range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions, will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine
braking.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
engine idle speed. Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
SNOW PLOW
Snow plows, winches, and other aftermarket
equipment should
not be added to the front end
of your vehicle. The airbag crash sensors may
be affected by the change in the front end
structure. The airbags could deploy
unexpectedly or could fail to deploy during a
collision.
WARNING!
Do not add a snow plow, winches, or any
other aftermarket equipment to the front of
your vehicle. This could adversely affect the
functioning of the airbag system and you
could be injured.
