SAFETY 239
NOTE:
In the event of a DDD system failure, a dedi-
cated message will appear in the instrument
cluster display.
DDD Warning Message
REAR SEAT REMINDER ALERT (RSRA)
RSRA will consider the presence of an object in
the rear seat when a rear entry/exit door is
opened at the beginning of each key cycle. To
activate, the rear door must be open for more
than one second and the vehicle must be
placed in the ON/RUN position within
10 minutes. When the potential presence of an
object is determined and/or otherwise inferred,
a message will appear in the instrument cluster
display reminding driver to check the rear
seat(s) immediately after key off accompanied
by an alert upon exiting the vehicle.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced EBC
system. This system includes the Anti-Lock
Brake System (ABS), Brake Assist System (BAS),
Electronic Brake Force Distribution (EBD),
Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), Hill Start Assist (HSA),
and Traction Control System (TCS). These
systems work together to enhance both vehicle
stability and control in various driving
conditions.
Your vehicle may also be equipped with
Dynamic Steering Torque (DST), Rain Brake
Support (RBS), Ready Alert Braking (RAB), and
Trailer Sway Control (TSC).
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
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
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
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.
