(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the ºONº position. It goes off after about 6 seconds. This
means the SRS airbags and seat belt pretensioners are
operating properly.
The SRS warning light system monitors the airbag sensor
assembly, front airbag sensors, side airbag sensors, curtain
shield airbag sensors, occupant detection sensor, seat belt
buckle switch, front seat belt pretensioner assemblies,
inflators, warning light, interconnecting wiring and power
sources.
If either of the following conditions occurs, 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.
When the ignition key is turned to the ªONº position, the light
does not come on, remains on or flashes.
The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags fail. If the light flashes, the side and curtain
shield airbags and/or seat belt pretensioners fail.
(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) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.
The light may occasionally flicker when the engine is idling or
it may come on briefly after a hard stop. There is no cause for
concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low. It
is not designed to indicate low oil level, and the oil level must
be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on ± even
for one block. It may ruin the engine.
(g) Low Engine Oil Level Warning Light
This light warns that the engine oil level is too low. Add oil as
soon as possible. (For instructions, see ºChecking the engine
oil levelº on page 253.)
While driving on steep inclines or rough roads which causes
the vehicle to substantially sway or on curves, this light may
come on due to the movement of engine oil in the engine.
NOTICE
Continued engine operation with low engine oil will
damage the engine.

(h) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See ºFuel gaugeº on
page 38 for instructions.)
b. The fuel tank cap is not tightened securely. (See ºFuel tank
capº on page 69 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 ªcº., 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.
(i) ºABSº Warning Light
The light comes on when the ignition key is turned to the ªONº
position. If the anti±lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
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 either of the following conditions occurs, 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 when the ignition key is turned
to the ªONº position, or remains on.
The light comes on while you are driving.
