SAFETY 145
ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will
turn on when the ignition is placed in the ON/
RUN mode and may stay on for as long as four
seconds.
If the “Anti-Lock Brake Warning 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 “Anti-Lock
Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the
brake system should be serviced as soon as
possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning Light”
does not come on when the ignition is placed in
the ON/RUN mode, have the light repaired as
soon as possible.
Electronic Brake Control (EBC) System
Your vehicle is equipped with an advanced Elec-
tronic Brake Control (EBC) System. This system
includes Electronic Brake Force Distribution
(EBD), Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Hill Start Assist (HSA),
Traction Control System (TCS), Electronic
Stability Control (ESC), and Electronic Roll Miti-
gation (ERM). These systems work together 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), and Hill Descent
Control (HDC).
Brake System Warning Light
The red “Brake System Warning Light” will turn
on when the ignition is placed in 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 placed in the ON/RUN mode,
have the light repaired as soon as possible.
Brake Assist System (BAS)
The Brake Assist System (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 applica-
tion 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 stop-
ping 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 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.
