264 SAFETY
The ESC Activation/Malfunction Indicator Light 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 the Traction Control System (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 is placed in the ON/RUN mode.

Each time the ignition is placed in the ON/RUN posi -
tion, 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 that the
Electronic Stability Control (ESC) is in a reduced
mode.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases
the brake while stopped on an incline, HSA will continue to
hold the brake pressure for a short period. If the driver
does not apply the throttle before this time expires, the
system will release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for HSA to
activate:

The feature must be enabled.

The vehicle must be stopped.

The parking brake must be off.
 The driver door must be closed. (If the doors are
attached, then the door must be closed. If the doors
are detached then the driver's seat belt must be
buckled.)

The vehicle must be on a sufficient grade.

The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).

HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK or NEUTRAL. For vehicles equipped with a
manual transmission, if the clutch is pressed, HSA will
remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, see
Ú
page 199 for further information.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
Rain Brake Support (RBS)
RBS 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
functions when the windshield wipers are in LO or HI
speed. When RBS is active, there is no notification to the
driver and no driver interaction is required.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur, such
as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active driving
involvement. It is always the driver’s responsibility to be
attentive to distance to other vehicles, people, and
objects, and most importantly brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
or serious personal injury.
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 resuming
acceleration, manually activate the trailer brake or
apply more vehicle brake pressure prior to releasing
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 colli -
sion or serious personal injury.
