(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.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(f) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See ºFuel gaugeº
on page 57 for instructions.)
b. The fuel tank cap is not tightened securely. (See
ºFuel tank capº on page 114 for instructions.)
c. There is a problem somewhere in your engine
electrical system, automatic transmission electrical
system or electronic throttle control system.
If it comes on while you are driving in case ªc.º, have your
vehicle checked/repaired by your Lexus dealer as soon
as possible.
If this lamp comes on and the engine speed does not
increase with the accelerator pedal depressed down to
about the middle position, there may be a problem
somewhere in your electronic throttle control system.
At this time, if you depress the accelerator pedal more
firmly and slowly, you can drive your vehicle at low
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
may not be recovered until the engine is stopped and the
ignition key is turned to ªACCº or ªLOCKº position.

(g) ºABSº Warning Light
The light comes on with the ignition key turned to ªONº.
If the anti±lock brake system and the brake assist
system work properly, the light goes out after a few
seconds. Thereafter, if either of the systems
malfunctions, the light comes on.
When the ªABSº warning light is on (and the brake
system warning light is off), the anti±lock brake system,
the brake assist system, the traction control system
and/or the vehicle skid control system do/does not
operate, but the brake system still operates
conventionally.
When the ªABSº warning light is on (and the brake
system warning light is off), the anti±lock brake system
does not operate so that the wheels could lock up during
a sudden braking or braking on slippery road surfaces.
If the following conditions occur, this indicates a
malfunction somewhere in the parts monitored by
the warning light system. Contact your Lexus
dealer as soon as possible to service the vehicle.
 The light does not come on with the ignition key
turned to ªONº, or remains on.
 The light comes on while driving.
If the light lit during driving goes out and does not come
on again, it is a normal operation.

closed.
(i) Low Fuel Level Warning Light

than usual.
