If tire 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 a 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.

"ABS" warning light
The light comes on with the ignition key
turned to the "ON" position. If the anti-
lock brake system works properly, the
light goes out after a few seconds. There-
after, if the system malfunctions, the light
comes on.
When the "ASS" warning light is on (and
the brake system warning light is off), the
anti-lock brake system does not operate,
but the brake system still operates con-
ventionally.
