306 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 position, 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 transmis-
sion, if the clutch is pressed, HSA will remain
active.
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 involve-
ment. 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 vehi-
cle. Failure to follow these warnings can
result in a collision or serious personal injury.
