SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking condi-
tions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When the
light is illuminated, the ABS is not functioning. The system
reverts to standard non-anti-lock brakes. Turning the igni-
tion OFF and ON again may reset the ABS if the fault
detected was only momentary.
WARNING!
•The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference caused
(Continued)
WARNING! (Continued)
by improperly installed or high output radio trans-
mitting equipment. This interference can cause pos-
sible loss of anti-lock braking capability. Installation
of such equipment should be performed by qualified
professionals.
• Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
• The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase brak-
ing or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.
88 SAFETY

When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as the
vehicle comes to a stop. This is the result of the system
reverting to the base brake system.
Engagement of the ABS may be accompanied by a pulsing
sensation. You may also hear a clicking noise. These
occurrences are normal and indicate that the system is
functioning properly.
Electronic Brake Control System
Your vehicle is equipped with an advanced electronic
brake control system that includes the Traction Control
System (TCS), Brake Assist System (BAS) and Electronic
Stability Control (ESC), Trailer Sway Control (TSC), and
Hill Start Assist (HSA). These systems complement the
Anti-Lock Brake System (ABS) by optimizing the vehicle
braking capability during emergency braking maneuvers.
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, brake pressure is applied to the slipping wheel(s)
and engine power is reduced, to provide enhanced accel-
eration and stability. A feature of the TCS system, Brake
Limited Differential (BLD), functions similar to a limitedslip 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. This feature remains active
even if the ESC is in the “Partial Off” mode.
The “ESC Activation/Malfunction Indicator Light” (in the
instrument cluster) will start to flash as soon as the tires
lose traction and the wheels begin to spin. This indicates
that the TCS is active. If the indicator light flashes 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, and do not
switch off the ESC or TCS.
WARNING!
•
The TCS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.
• The TCS cannot prevent collisions, including those
resulting from excessive speed in turns, or hydro-
planing.

WARNING!(Continued)
•The capabilities of a TCS-equipped vehicle must
never be exploited in a reckless or dangerous man-
ner, which could jeopardize the user’s safety or the
safety of others.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The sys-
tem detects an emergency braking situation by sensing the
rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the anti-lock
brake system (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking pressure
during the stopping sequence, (do not “pump” the brakes).
Do not reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released, the BAS is
deactivated.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The capa-
bilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user’s safety or the safety of
others.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) enhances directional
control and stability of the vehicle under various driving
conditions. ESC corrects for over/under steering of the
vehicle by applying the brake of the appropriate wheel to
assist in counteracting the over/under steer condition.
Engine power may also be reduced to help the vehicle
maintain the desired path.
90 SAFETY

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 appropriate
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.
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 hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
(Continued)
WARNING! (Continued)
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities 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.
• Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly
worn tires may also degrade ESC performance. Any
vehicle modification or poor vehicle maintenance
that reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

SAFETY 91

ESC Operating Modes
The “ESC Off” switch is located in the center
switch bank, next to the hazard flasher switch.
ESC On
This mode is the normal operating mode for ESC equipped
vehicles. Whenever the vehicle is started, the ESC system
will be in this mode. This mode should be used for most
driving situations. ESC should only be turned off for
specific reasons as noted below.
ESC Partial Off
This mode is entered by momentarily pushing the “ESC
Off” switch.
When in the “Partial Off” mode, the TCS portion 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 the “Partial Off” mode,
ESC will operate without engine torque management. 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 push the “ESC Off” switch.
This will restore the normal “ESC On” mode of operation.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.
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 pushing the “ESC Off” switch. Once the situation
requiring ESC to be switched to the “Partial Off” mode is
overcome, turn ESC back on by momentarily pushing the
“ESC Off” switch. This may be done while the vehicle is in
motion.
92 SAFETY

ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition is turned to the ON mode. It should go
out with the engine running. If the ESC
Activation/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 Activation/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
Activation/Malfunction Indicator Light also flashes when
TCS is active. If the ESC Activation/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 Activation/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.
The ESC OFF Indicator Light indicates the Elec-
tronic Stability Control (ESC) is off.
Trailer Sway Control (TSC) — If Equipped
TSC uses sensors in the vehicle to recognize an excessively
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 appropriate wheel(s) to
counteract the sway of the trailer. TSC will become active
automatically once an excessively swaying trailer is recog-
nized.
5
SAFETY 93

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 Tow-
ing” 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” 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.
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
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.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
WARNING!
•
If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resum-
ing acceleration, manually activate the trailer brake
or apply more vehicle brake pressure prior to releas-
ing the brake pedal.
• HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle. Also,
be certain to place the transmission in PARK.
• Failure to follow these warnings can result in a
collision or serious personal injury.
