D
Even though the anti−lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering
speeds, or in violent maneuvers.
D
Avoid high speeds on wet roads. The
anti−lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with
vehicles not fitted with an anti−lock brake
system, your vehicle may require a longer
stopping distance in the following cases:
D
Driving on rough, gravel or snow−cov-
ered roads.
D
Driving with tire chains installed.
D
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.

"ABS" warning light
The light comes on when the ignition key
is turned to the "ON" position. After a few
seconds, the light will go off.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
D
The light does not come on as de-
scribed above, or remains on.
D
The light comes on while driving.
Even if the anti−lock brake system should
fail, the brake system will still operate
conventionally. However, when the "ABS"
warning light is on (and the brake system
warning light is off), the anti−lock brake
system is not assisting brake performance
so that the wheels can lock−up during
sudden braking or braking on slippery
road surfaces. Have your vehicle checked
by your Toyota dealer as soon as pos-
sible.
