counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Malfunction Indicator Light” located in the
instrument cluster will start to flash as soon as the tires lose
traction and the ESC system becomes active. The “ESC
Malfunction Indicator Light” also flashes when the TCS is
active. If the “ESC Malfunction Indicator Light” begins toflash during acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents resulting from loss
of vehicle control due to inappropriate driver input
for the conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ESC equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopardize
the user ’s safety or the safety of others.

STARTING AND OPERATING 471

The ESC system has two available operating modes in
AWD AUTO range and two-wheel drive vehicles, and
one operating mode in AWD LOW range.
AUTO Range (All-Wheel Drive Models) Or
Two-Wheel Drive Models
On
This is the normal operating mode for ESC in AWD
AUTO range and in two-wheel drive vehicles. Whenever
the vehicle is started or the transfer case (if equipped) is
shifted from AWD LOW range or NEUTRAL back to
AWD AUTO range, the ESC system will be in this “On”
mode. This mode should be used for most driving
situations. ESC should only be turned to “Partial Off”
mode for specific reasons as noted below.Partial Off
This mode is entered by momentarily pressing the “ESC
OFF” switch. When in “Partial Off” mode, the TCS
portion of ESC, except for the BLD feature described in
the TCS section, has been disabled and the “ESC Off
Indicator Light” will be illuminated. The enhanced ve-
hicle stability offered by the ESC system is reduced. This
mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin
than ESC would normally allow is required to gain
traction. To turn ESC on again, momentarily press the
“ESC OFF” switch. This will restore the normal “ESC
On” mode of operation.
472 STARTING AND OPERATING

NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC OFF” switch. Once the
situation requiring ESC to be switched to the “Partial Off” mode is overcome, turn ESC back on by momen-
tarily pressing the “ESC OFF” switch. This may be done
while the vehicle is in motion.
WARNING!
•When in “Partial Off” mode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed 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.

STARTING AND OPERATING 473

AWD Low Range (LOW)
Partial Off
This is the normal operating mode for ESC in AWD LOW
range. Whenever the vehicle is started in AWD LOW
range, or the transfer case (if equipped) is shifted from
AWD AUTO range or NEUTRAL to AWD LOW range,
the ESC system will be in the “Partial Off” mode.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. Note that 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 “Startingand Operating” for further information. When TSC is
functioning, the “ESC 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” mode.
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.
•TSC is disabled when the ESC system is in the
“Partial Off” mode.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
474 STARTING AND OPERATING

brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to the
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
•Vehicle must be on a 6% (approximate) grade or
greater hill.
•Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).HSA will work in REVERSE and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.

STARTING AND OPERATING 475

HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.
WARNING!
•If you use a trailer brake controller with your
trailer, your trailer brakes may be activated and
deactivated with the brake switch. If so, when the
brake pedal is released, there may not be enough
brake pressure to hold the vehicle and trailer on a
hill and this could cause a collision with another
vehicle or object behind you. In order to avoid
rolling down the hill while resuming acceleration,
manually activate the trailer brake prior to releas-
ing the brake pedal. Always remember the driver
is responsible for braking the vehicle.(Continued)
WARNING! (Continued)
•HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, it can be done
using the Customer Programmable Features in the Elec-
tronic Vehicle Information Center (EVIC). Refer to “Elec-
tronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.
476 STARTING AND OPERATING

Ready Alert Braking
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.
It anticipates when an emergency braking situation may
occur by monitoring how fast the throttle is released by
the driver. When the throttle is released very quickly,
Ready Alert Braking applies a small amount of brake
pressure. This brake pressure will not be noticed by the
driver. The brake system uses this brake pressure to allow
a fast brake response if the driver applies the brakes.
Rain Brake Support
Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It only functions when the
windshield wipers are in the slow or fast mode, it does
not function in the intermittent mode. When Rain Brake
Support is active, there is no notification to the driver and
the driver should not notice it.
ESC Malfunction Indicator Light And ESC OFF
Indicator Light
The “ESC Malfunction Indicator Light” in the
instrument cluster will come on when the
ignition switch is turned to the ON position. It
should go out with the engine running. If the
“ESC Malfunction Indicator Light” comes on continu-
ously with the engine running, a malfunction has been
detected in the ESC system. If this light remains on after
several ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is off.
5
STARTING AND OPERATING 477

The “ESC Malfunction Indicator Light” (located in the
instrument cluster) starts to flash as soon as the tires lose
traction and the ESC system becomes active. The “ESC
Malfunction Indicator Light” also flashes when TCS is
active. If the “ESC Malfunction Indicator Light” begins to
flash during acceleration, ease up on the accelerator and
apply as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
NOTE:
•The “ESC Malfunction Indicator Light” and the “ESC
OFF Indicator Light” come on momentarily each time
the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
