Antilock Brake System (ABS)
Warning Light
This light comes on briefly when the engine
control switch is turned to the ON position,
and then should go out after approximately
three seconds. If the light does not come on,
have it fixed so it will be ready to warn if
there is a problem.
If this warning light stays on more than
three seconds or comes on while driving, the
ABS has a problem. In this case, the ABS
stops working but the brakes still function
as ordinary service brakes.

Warning
If this warning light comes on while
driving, immediately stop your vehicle at
a safe place well clear of traffic and take
the following actions.
1. Stop the engine.
Warning (Continued)
2. Restart the engine. Check if the ABS
warning light comes on and then
goes out. If it does, there is no
problem. The ABS operates normally.
3. Move the vehicle slowly forward.
Gradually increase the speed to
15 km/h (9 mph). If the light goes
off, the ABS is normal.
If the light does not come on or go out,
or comes on frequently, contact your
dealer immediately and have the system
repaired.
Even if a problem has occurred in the
ABS, the brakes will still work as normal
brakes. In this case, the ABS has no
influence on the operation of the brake
system.
