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.
• The BAS cannot prevent collisions, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing.
• 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.
Traction Control System (TCS)
This system 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 acceleration 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. 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.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•
Vehicle must be stopped.
• Vehicle must be on a 2.5% (manual transmission) or
7% grade or greater (automatic transmission) hill.
