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 vehicle
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 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.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteering or understeering condi-
tion. Vehicle power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by
the driver and compares it to the actual path of the
vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or under-
steer condition.
• Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
