(e) Malfunction Indicator Lamp
This lamp comes on when the ignition key is turned to the
“ON” 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 does not go off even after 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 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 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 “ACC” or “LOCK” 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)
programs” on page 489.

(f) “ABS” Warning Light
The light comes on when the ignition key is turned to the “ON”
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 “ABS” 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
When the “ABS” 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 “ON” 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 “ABS” 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 antilock 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 “ON” 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.

goes off. If the light goes off, you can start the vehicle again.

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.
(n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This 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.
Reset the light by following the procedure below:
1. Turn the ignition key to the “ACC” or “LOCK” position with
the odometer reading shown. (For details, see “Odometer and

(including the spare tire) is low. The light comes on when
the ignition key is turned to the “ON” position. It goes off after
a few seconds. This indicates that the tire pressure warning
system is functioning properly.

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
