SAFETY FEATURES

Anti-Lock Brake System (ABS)

The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock,
and enhances vehicle control during braking.

The ABS performs a self-check cycle to en-
sure that the ABS is working properly each
time the vehicle is started and driven. During
this self-check, you may hear a slight clicking
sound as well as some related motor noises.

ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow,
gravel, bumps, railroad tracks, loose debris,
or panic stops may increase the likelihood of
ABS activation(s).

You also may experience the following when
ABS activates:

• The ABS motor noise (it may continue to

run for a short time after the stop).

• The clicking sound of solenoid valves.

• Brake pedal pulsations.

• A slight drop of the brake pedal at the end

of the stop.

These are all normal characteristics of ABS.

WARNING!

• The ABS contains sophisticated elec-

tronic equipment that may be suscep-
tible to interference caused by improp-
erly installed or high output radio
transmitting equipment. This interfer-
ence can cause possible loss of anti-lock
braking capability. Installation of such
equipment should be performed by
qualified professionals.

WARNING!

• Pumping of the Anti-Lock Brakes will

diminish their effectiveness and may
lead to a collision. Pumping makes the
stopping distance longer. Just press
firmly on your brake pedal when you
need to slow down or stop.

• The ABS cannot prevent the natural laws

of physics from acting on the vehicle,
nor can it 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, in-

cluding those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.

• The capabilities of an ABS equipped

vehicle must never be exploited in a
reckless or dangerous manner that could
jeopardize the user’s safety or the safety
of others.

ABS is designed to function with the OEM
tires. Modification may result in degraded
ABS performance.
