WARNING! (Continued)
• The Anti-Lock Brake System (ABS) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can they increase
braking or steering efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
• The ABS cannot prevent collisions, includ-
ing those resulting from excessive speed
in turns, following another vehicle too
closely, or hydroplaning.
• The capabilities of an ABS-equipped ve-
hicle must never be exploited in a reckless
or dangerous manner which could jeopar-
dize the user's safety or the safety of others.
CAUTION!
The Anti-Lock Brake System is subject to
possible detrimental effects of electronic in-
terference caused by improperly installed
aftermarket radios or telephones.

NOTE:
During severe braking conditions, a pulsing
sensation may occur and a clicking noise
will be heard. This is normal, indicating that
the Anti-Lock Brake System is functioning.

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 slip-
ping 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 sys-
tem 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
either the "Partial Off" or "Full Off" modes. Refer
to "Electronic Stability Control (ESC)" in this
section for further information.

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 comple-
ments the anti-lock brake system (ABS). Apply-
ing 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
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 pre-
vent the natural laws of physics from acting
on the vehicle, nor can it increase the trac-
tion afforded by prevailing road conditions.
The BAS cannot prevent collisions, including
