When the anti − lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
!
You may hear the anti − lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
!
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.
Anti
− lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at the moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti
− lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
!
Driving on rough, gravel or snow −
covered roads.
!
Driving with tire chains installed.
!
Driving over the steps such as the
joints on the road.
!
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti − lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.
