STARTING AND OPERATING 423

PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while vehicle is in motion.
Apply the parking brake when leaving vehicle in this
range.
When parking on a level surface, you may place the shift
lever in the PARK position first, and then apply the
parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever rearward (with the brake
pedal released), after you have placed it in PARK.
Make sure the transmission is in PARK before
leaving the vehicle.(Continued)
434 STARTING AND OPERATING

Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the shift
lever to the left (-) will downshift the transmission,
activate ERS mode, display the current gear in the
instrument cluster, and maintain that gear as the top
available gear. Once in ERS mode, tapping the shift lever
to the left (-) or right (+) will change the top available
gear.To exit ERS mode, simply press and hold the shift lever to
the right (+) until “D” is once again displayed in the shift
lever position indicator in the instrument cluster.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing an accident
or personal injury.

Actual Gear(s) Allowed 1 1-2 1-3 1-4 1-5
NOTE: To select the proper gear position for maximum
deceleration (engine braking), simply press and hold the
shift lever to the left (-). The transmission will shift to the
range from which the vehicle can best be slowed down.

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while vehicle is in motion.
Apply the parking brake when leaving vehicle in this
range.
When parking on a level surface, you may place the shift
lever in the PARK position first, and then apply the
parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.

If the transmission cannot be reset, authorized dealer
service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
Use of ERS (or TOW/HAUL mode) also enables an
additional underdrive gear which is not normally used
during through-gear accelerations. This additional gear
can improve vehicle performance and cooling capability
when towing a trailer on certain grades. In ERS mode,
gears 1 though 3 are underdrive gears, and ERS 4 is direct
drive. ERS 5 and 6 (Overdrive gears ) are the same as the
normal fourth and fifth gears.You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the shift
lever to the left (-) will activate ERS mode, display the
current gear in the instrument cluster, and maintain that
gear as the top available gear. Once in ERS mode, tapping
the shift lever to the left (-) or right (+) will change the top
available gear.
To exit ERS mode, simply press and hold the shift lever to
the right (+) until “D” is once again displayed in the shift
lever position indicator in the instrument cluster.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing an accident
or personal injury.

STARTING AND OPERATING 447

Electronic Range Select (ERS) feature, when the trans-
mission is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds after starting the
engine.
ALL-WHEEL DRIVE OPERATION
Single-Speed Operating Instructions/Precautions
(3.6L Engine) – If Equipped
This system contains a single-speed (HI range only)
transfer case, which provides convenient full-time all-
wheel drive. No driver interaction is required. The Brake
Traction Control (BTC) System, which combines standardABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:
This system is not appropriate for conditions
where LOW range is recommended. Refer to “Off-Road
Driving Tips” in “Starting and Operating” for further
information.
Electronically Shifted Transfer Case
(Three-Position Switch) (5.7L Engine) – If
Equipped
This is an electronic shift transfer case and it is operated
by the AWD Control Switch, which is located on the
center console.
450 STARTING AND OPERATING

This electronically shifted transfer case provides three
mode positions:
•All-wheel drive automatic range (AWD AUTO)
•All-wheel drive low range (LOW RANGE)
•Neutral (NEUTRAL)This electronically shifted transfer case is designed to be
driven in the AWD AUTO position for normal street and
highway conditions on dry hard surfaced roads.
For variable driving conditions, the AWD AUTO mode
can be used. In this mode, the front axle is engaged, but
the vehicle’s power is sent to the rear wheels. All-wheel
drive will be automatically engaged when the vehicle
senses a loss of traction.
When additional traction is required, the transfer case
LOW RANGE position can be used to lock the front and
rear driveshafts together forcing the front and rear wheels
to rotate at the same speed. This is accomplished by
rotating the AWD Control Switch to the desired position.
Refer to “Shifting Procedure” for specific shifting instruc-
tions. The LOW RANGE position is designed for loose,
slippery road surfaces only. Driving in the LOW RANGE
position on dry hard surfaced roads may cause increased
tire wear and damage to the driveline components.

STARTING AND OPERATING 451

Transfer Case Position Indicator Messages
The Transfer Case Position Indicator messages (AWD
AUTO and LOW RANGE) are located in the EVIC
(Electronic Vehicle Information Center) and indicate the
current and desired transfer case selection. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. When you select a different transfer case position,
the position indicator lights will do the following:
If All 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 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 notshift.
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, turn
the control knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedure for your transfer
case, located in this section of the owner’s manual.
The “SERV AWD Warning Light” monitors the electronic
shift all-wheel drive system. If this light remains on after
