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.

(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 Checking the engine
oil levelº on page 329.)
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.In normal conditions, due to engine oil consumption, this light
may come on earlier than the specified service interval of the
scheduled maintenance. This is because the engine oil is
consumed to the low level within the scheduled maintenance
interval and does not indicate a problem. (For detailed
information, see Facts about engine oil consumptionº on page
327.)
NOTICE
Continued engine operation with low engine oil will
damage the engine.

(h) Engine Oil Replacement Reminder Light (for
vehicles sold in U.S.A.)
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to the
ONº position 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 the ONº position. If you continue driving
without replacing the engine oil, and if the distance driven
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to the 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 conditions. If the light comes on, replace it as soon as
possible.
The system must be reset after the engine oil replacement.
Reset the system by the following procedure:
1. Turn the ignition key to the OFFº position with the odometer
reading shown. (For details, see Odometer and trip meterº on
page 52.)
2. Turn the ignition key to the ONº position while holding down
the trip meter reset knob.
Hold down the knob for at least 5 seconds. The odometer
indicates 000000º and the light goes off.
If the system fails to reset, the light will continue flashing.
(i) 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 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 your
electronic throttle control system.

Finish
GAUGES, METERS AND SERVICE REMINDER INDICATORS
62At 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 the 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 311.
(j) ABSº Warning Light
Vehicles without vehicle stability control system Ð
The light comes on with the ignition key turned to the ONº
position. If the anti-lock brake system works properly, the light
turns off after a few seconds. Thereafter, if the system
malfunctions, the light comes on again.
When the ABSº warning light is on (and the brake system
warning light is off), the anti-lock brake system does not
operate, but the brake system still operates conventionally.
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 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 components monitored
by the warning light. 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.

NOTICE
A large amount of unburned gases flowing into the
three-way catalytic converter may cause it to overheat
and create a fire hazard. To prevent this and other
damage, observe the following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low fuel level; running
out of fuel could cause the engine to misfire, creating
an excessive load on the three-way catalytic
converter.
Do not allow the engine to run at idle speed for more
than 20 minutes.
Avoid racing the engine.
Do not push-start or pull-start your vehicle.
Do not turn off the ignition while the vehicle is
moving.
Keep your engine in good running order.
Malfunctions in the engine electrical system,
electronic ignition system/distributor ignition
system or fuel system could cause an extremely high
three-way catalytic converter temperature.
If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check-up as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its three-way catalytic
converter system best.
