gether to enhance both vehicle stability and
control in various driving conditions.
Your vehicle may also be equipped with Trailer
Sway Control (TSC), Ready Alert Braking
(RAB), Rain Brake Support (RBS), Dynamic
Steering Torque (DST), Hill Descent Control
(HDC), and Selec-Speed Control (SSC).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the
braking torque between the front and rear axles
by limiting braking pressure to the rear axle. This
is done to prevent overslip of the rear wheels to
avoid vehicle instability, and to prevent the rear
axle from entering ABS before the front axle.
Brake System Warning Light
The red "Brake System Warning Light" will turn
on when the ignition is turned to the ON/RUN
mode and may stay on for as long as four
seconds.
If the "Brake System Warning Light" remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the "Brake
System Warning Light" does not come on when
the ignition is turned to the ON/RUN mode, have
the light repaired as soon as possible.
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 sensing the rate and
amount of brake application and then applies
optimum pressure to the brakes. This can help
reduce braking distances. The BAS comple-
ments the anti-lock brake system (ABS). Apply-
ing 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 pre-
vent 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 re-
sulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning.
The capabilities 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.
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.
• Park brake must be off.
• Driver door must be closed.
• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in for-
ward gear; vehicle backing uphill is in RE-
VERSE 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 trans-
mission, 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 roll-
ing 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 respon-
