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 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 man-
ner, which could jeopardize the user’s safety or the
safety of others.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount of
wheel spin of each of the driven wheels. If wheel spin is
detected, brake pressure is applied to the slipping wheel(s)
and engine power is reduced to provide enhanced accel-
eration and stability. A feature of the TCS system, Brake
Limited Differential (BLD), functions similar to a limited
slip differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster than
the other, the system will apply the brake of the spinning
wheel. This will allow more engine torque to be applied to
the wheel that is not spinning. This feature remains active
even if TCS and ESC are in the Partial Off mode or Full Off
mode. Refer to “Electronic Stability Control (ESC)” in this
section for further information.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes his foot off the brake
pedal. If the driver does not apply the throttle during this
short period of time, the system will release brake pressure
and the vehicle will roll down the hill. The system will
release brake pressure in proportion to the amount of
throttle applied as the vehicle starts to move in the
intended direction of travel.
