(e) Malfunction Indicator Lamp
This lamp comes on when the ignition key is turned to the
ONº position and goes off after the engine starts. This
means that the warning light system is operating properly.
If the lamp remains on, or the lamp comes on while driving,
first check the followings.
Empty fuel tank
If the fuel tank is empty, refuel immediately.
Loose fuel tank cap
If the fuel tank cap is loose, securely tighten it.
These cases are temporary malfunctions. The malfunction
indicator lamp will go off after taking several driving trips.
If the lamp will not go off even after the several trips, contact
your Lexus dealer as soon as possible.
If the fuel tank is not empty or the fuel tank cap is not
loose...
There is a problem somewhere in the engine, emission
control system, electronic throttle control system, automatic
transmission electrical system or warning light system itself.
Contact your Lexus dealer as soon as possible to service the
vehicle.
If the engine speed does not increase with the accelerator
pedal depressed down, there may be a problem somewhere
in your 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 vehicle 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 ACCº or LOCKº position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.
Emissions inspection and maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle's emission control system and
OBD (On-Board Diagnostics) system before taking your
vehicle for the inspection.
For details, see Emissions inspection and maintenance (I/M)
programsº on page 519.

(f) ABSº Warning Light
The light comes on when the ignition key is turned to the ONº
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 ABSº warning light is on (and the brake system
warning light is off), the following systems do not operate, but
the brake system still operates conventionally.
Anti-lock brake system
Brake assist system
Active traction control system
Vehicle stability control system
Downhill assist control system
Hill-start assist control system
When the ABSº warning light is on (and the brake system
warning light is off), the anti-lock brake system does not
operate, so that the wheels will 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 components 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 ONº position, or remains on.
The light comes on while you are driving.A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the ABSº warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the anti-lock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Either of the following conditions may occur, but do not
indicate a malfunction:
The light may stay on for about 60 seconds after the ignition
key is turned to the ONº position. It is normal if it turns off
after a while.
Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.

This light warns that there is a problem somewhere in the
following.
Vehicle stability control system
Active traction control system
Downhill assist control system
Hill-start assist control system
The light will come on when the ignition key turned to ONº, and
will go off after a few seconds.
It is not a malfunction that the warning light may stay on for 60
seconds after the ignition key is turned to the ONº position.
Depressing the brake pedal repeatedly may turn on the lights.
It is normal if they go out after a few seconds.
There is no problem when the VSC TRACº warning light
comes on when the brake actuator temperature becomes high.
If the light comes on while driving, the above mentioned
systems do not work. However, as conventional braking
operates when applied, there is no problem to continue your
driving.
In the following cases, contact your Lexus dealer:
The warning light does not come on after the ignition key is
turned to ONº.
The warning light remains on after the ignition key is turned
to ONº.

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.

(n) Engine Oil Replacement Reminder Light
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to ONº
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 ONº 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 ONº 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.

1. Turn the ignition key to the OFFº position with the odometer
reading shown. (For details, see Odometer and trip meterº on

illuminates for 1 second.
If the system fails to reset, the light will remain flashing. In this
case, return to step 1 and try again.

system is functioning properly.
If the warning light comes on, stop your vehicle in a safe place
as soon as possible and check that the inflation pressure of all
tires (including the spare tire) is as specified on the tire and
loading information label. (See Checking tire inflation
pressureº on page 557.) The light should go off a few minutes
after the tire pressure is adjusted.
If the warning light blinks, the tire pressure warning system
may be malfunctioning. Contact your Lexus dealer.
For details, see Tire pressure warning systemº on page 417.

This light comes on when the fuel level in the tank becomes
very low. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.
