key is turned to the ªONº position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the

turned to ªONº.
 The warning light remains on after the ignition key is turned
to ªONº.

If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
