ACTIVE SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically prevents
wheel lock, and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure 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 begins to lock. Road conditions such
as ice, snow, gravel, bumps, railroad tracks, loose debris,
or panic stops may increase the likelihood of ABS activa-
tion(s).
You also may experience the following when ABS acti-
vates:
•
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 electronic equip-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa-
bility. Installation of such equipment should be
performed by qualified professionals.
