Any of the following conditions may occur, but do not
indicate the malfunction:

The light may stay on for about 60 seconds after the ignition
key is turned to the “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.
 You may hear a small sound in the engine compartment
after the engine is started or the brake pedal is depressed
repeatedly. This is a pump pulsating sound of the brake
system, and it is not a malfunction.
(b) Driver’s Seat Belt Reminder Light and
Buzzer
The light and buzzer act as a reminder to buckle up the driver’s
seat belt.
Once the ignition key is turned to “ON” or “START”, the
reminder light flashes and buzzer sounds if the driver’s seat
belt is not fastened. Unless the driver fastens the belt, the light
continues flashing and the buzzer stops after about 4 to 8
seconds.
(c) Front Passenger’s Seat Belt ReminderLight
The light acts as a reminder to have the front passenger buckle
up the seat belt.
Once the ignition key is turned to “ON” or “START”, the
reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt. Unless the front
passenger fastens the belt, the light continues flashing.
If luggage or other load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built−in sensors in the seat cushion may detect the pressure,
causing the reminder light to flash.

(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the “ON” 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 and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front passenger occupant cassification system and indicator
light, front passenger seat belt buckle switch, inflators, seat
belt pretensioners, roll sensing of curtain shield airbags off
indicator light, interconnecting wiring and power sources.
If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.

to the “ON” position or remains on for more than 6 seconds
or flashes.

(e) Engine Oil Replacement Reminder Light (U.S.A. only)
The light acts as a reminder to replace the engine oil.
This light will come on when the ignition key is turned to “ON”
and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to “ON” position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to “ON” position. The light will remain on\
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible.
You need to reset the light after the engine oil replacement.

 Empty fuel tank
If the fuel tank is empty, refuel immediately.

control system, electronic throttle control system, automatic
transmission electrical system or warning light system itself.

If engine speed does not increase when the accelerator pedal
is depressed, there may be a problem somewhere in the
electronic throttle control system. At this time, vibration may occur. However, 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 “ACC” or “LOCK” position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.
Emissions inspection and maintenance (I/M) programs
