SAFETY 203
ESC Operating Modes
NOTE:
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions. Alter-
nate ESC modes should only be used for specific reasons as
noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which allows
for more wheel spin than normally allowed. This mode may
be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light” will illumi -
nate. To turn the ESC on again, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light” will turn off. NOTE:
For vehicles with multiple partial ESC modes a momentary
button push will toggle the ESC mode. Multiple momentary
button pushed may be required to return to ESC On.
Full Off — If Equipped
This mode is intended for off-highway or off-road use only
and should not be used on any public roadways. In this
mode, TCS and ESC features are turned OFF. To enter the
“Full Off” mode, push and hold the “ESC Off” switch for five
seconds while the vehicle is stopped with the engine
running. After five seconds, a chime will sound, the “ESC Off
WARNING!
• When in “Partial Off” mode, the TCS functionality of ESC, (except for the limited slip feature described in
the TCS section), has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of TCS
is disabled, and the enhanced vehicle stability offered
by the ESC system is reduced.
• Trailer Sway control (TSC) is disabled when the ESC system is in the “Partial Off” mode.

6. Push the “ESC Off” button located in the lower switch bankbelow the climate control four times within 20 seconds. The
“ESC Off Indicator Light” should turn on and turn off two
times.

7. Rotate the steering wheel back to center and then an addi -
tional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount of
wheel spin of each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the spinning
wheel(s) and/or reduce engine power to provide enhanced
acceleration and stability. A feature of the TCS, Brake
Limited Differential (BLD), functions similar to a limited slip
differential and controls the wheel spin across a driven axle.
If one wheel on a driven axle is spinning faster than the other,
the system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
ESC are in a reduced mode.
Trailer Sway Control (TSC)
Trailer Sway Control (TSC) uses sensors in the vehicle to
recognize an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway. TSC will
become active automatically once an excessively swaying
trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting And Operating” for further information.
When TSC is functioning, the “ESC Activation/Malfunction
Indicator Light” will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” or “Full
Off” modes.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

AutoPark — Rotary Shifter and 8-Speed Transmission
Only
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK. The conditions under which AutoPark will engage are
outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to place the vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the Instrument
Cluster Display and near the gear selector. If the "P"
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not designed to replace the need to shift your vehicle into PARK. It is
a back up system and should not be relied upon as the
primary method by which the driver shifts the vehicle
into PARK.

312 STARTING AND OPERATING
NEUTRAL (N)
Neutral — 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 section for further information.This electronically shifted transfer case is designed to be
driven in the two–wheel drive position (2WD) for normal
street and highway conditions on dry hard surfaced roads).
Driving the vehicle in 2WD will have greater fuel economy
benefits as the front axle is not engaged in 2WD.
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 4WD control switch.
Refer to “Shifting Procedure” in this section for specific
shifting instructions.
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 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 recreational towing only. Refer to “Recre
-
ational Towing” in “Starting And Operating” for further
information.
WARNING!
• You or others could be injured or killed if you leave the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The transfer case NEUTRAL (N)
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 transmis -
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.

316 STARTING AND OPERATING
This electronically shifted transfer case is designed to be
driven in the two–wheel drive position (2WD) or four-wheel
drive auto position (4WD AUTO) for normal street and
highway conditions on dry, hard surfaced roads. Driving the
vehicle in 2WD will have greater fuel economy benefits as
the front axle is not engaged in 2WD.For variable driving conditions, the 4WD AUTO mode can
be used. In this mode, the front axle is engaged, but the
vehicle's power is sent to the rear wheels. Four-wheel drive
will be automatically engaged when the vehicle senses a loss
of traction. Because the front axle is engaged, this mode will
result in lower fuel economy than the 2WD mode.
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
pushing the desired position on the 4WD Control Switch.
Refer to “Shifting Procedure” in this section for specific
shifting instructions.

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 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 recreational towing only. Refer to “Recreational Towing” in
“Starting And Operating” for further information.

WARNING!
• You or others could be injured or killed if you leave the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The transfer case NEUTRAL (N)
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 transmis -
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.
