(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 110 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.
(g) ºABSº Warning Light
This light warns that there is a problem somewhere in
your anti±lock brake system.
If the light comes on while you are driving, have your
vehicle checked by your Lexus dealer as soon as
possible.
The light will come on when the ignition key is turned to
ºONº, and will go off after about a few seconds.
When the ºABSº warning light is on (and the brake
system warning light is off), the brake system operates
conventionally but anti±lock brake system is not
assisting brake performance so that the wheels could
lock up during a sudden brake or braking on slippery

ºLOCKº ± Engine is off and the steering wheel is
locked. The ignition key can be removed only at this
position.
To turn the key from ºACCº to the ºLOCKº position, you
must put the transmission selector lever in the ºPº
position.
Once you remove the key, the engine immobiliser
system is automatically set. See ºEngine immobiliser
systemº on page 15.
When starting the engine, the key may seem stuck at the
ºLOCKº position. To free it, first be sure the key is
pushed all the way in, and then rock the steering wheel
slightly while turning the key gently.
If, in an emergency, you must turn the engine off while
the vehicle is moving, turn the key only to ºACCº.
