ANTI–LOCK BRAKE SYSTEM
(with "ABS" warning light)
The anti–lock brake system is designed
to automatically help prevent lock–up of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti–lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti–lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking perfor-
mance.
The anti–lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).

Depressing the brake pedal on slippery
road surfaces such as on the manhole
cover, the steel plate under the construc-
tion, joints in the bridge, etc. on a rainy
day tends to activate the anti–lock brake
system.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle is started. This means that the
anti–lock brake system is in the self
check mode, and does not indicate a mal-
function.
When the anti–lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
D
You may hear the anti–lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the body
and steering wheel. You may also hear
the motor sound in the engine compart-
ment even after the vehicle is stopped.
D
At the end of the anti–lock brake sys-
tem activation, the brake pedal may
move a little forward.

CAUTION
Do not overestimate the anti–lock
brake system: Although the anti–lock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti–
lock brake system on.
If tires grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the anti–lock brake system does not
provide vehicle control.
