(e) Discharge Warning Light
This light warns that the battery is being discharged.
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
charging system.
The engine ignition will continue to operate, however,
until the battery is discharged. Turn off the air
conditioning, blower, radio, etc., and drive directly to the
nearest Lexus dealer or repair shop.

vehicle checked/repaired by your Lexus dealer as soon

speeds. Have your Lexus checked by your Lexus dealer
as soon as possible.
Even if the abnormality of the electronic throttle control
system is corrected during low speed driving, the system
