ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESC. This
system includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Traction Control System (TCS),
Electronic Roll Mitigation (ERM), Electronic Stability
Control (ESC), and Trailer Sway Control (TSC). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as somerelated motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS is
working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into Anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•The clicking sound of solenoid valves,
•Brake pedal pulsations, and
•A slight drop or fall away of the brake pedal at the end
of the stop.
354 STARTING AND OPERATING

Anti-Lock Brake Light
The Anti-Lock Brake Light monitors the ABS.
The light will turn on when the ignition switch
is turned to the ON position and may stay on
for as long as four seconds.
If the ABS Light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the Brake System Warning Light is not on.
If the ABS Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock brakes. If the ABS Light does not come on
when the ignition switch is turned to the ON position,
have the light repaired as soon as possible. If both the Brake System Warning Light and the ABS
Light remain on, the ABS and Electronic Brake Force
Distribution (EBD) systems are not functioning. Immedi-
ate repair to the ABS system is required.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing 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
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.

•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
Electronic Stability Control (ESC) is off.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer. TSC activates automatically once
the excessively swaying trailer is recognized. When TSC
is functioning, the “ESC Activation/Malfunction Indica-
tor Light” will flash, the engine power will be reduced,
and you will feel the brake being applied to individual
wheels in an attempt to stop the trailer from swaying.
NOTE: The TSC is disabled when the ESC system is in
the “Partial Off” mode.
WARNING!
•TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
tongue weight recommendations. Refer to ”Ve-
hicle Loading” and “Trailer Towing” in “Starting
and Operating” for further information.
•If TSC activates while towing a trailer, stop the
vehicle at the nearest safe location and adjust the
trailer load to eliminate the trailer sway.
•Failure to follow these warnings can result in an
accident or serious personal injury.

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes, and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing, you should allow for ad-
ditional space between your vehicle and the ve-
hicle in front of you. Failure to do so could result
in a collision.
Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting or
riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Master Cylinder – Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the “Brake Warning Light” indicates system failure.Check the fluid level in the master cylinder when per-
forming underhood services.
Clean the top of the master cylinder area before removing
the cap. If necessary, add fluid to bring the fluid level up
to the requirements described on the brake fluid reser-
voir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Fluid level can be expected to fall as the brake pads wear.
Brake fluid level should be checked when pads are
replaced. However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
