(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 ± evenfor 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 ªChecking the engine
oil levelº on page 333.)
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 ªFacts about engine oil consumptionº on page
331.)
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 acts as a reminder to replace the engine oil.
This light will come on when the ignition key is turned to the
ªONº 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 ªONº position. If you continue driving
without replacing the engine oil, and if the distance driven
exceeds 8000 km (5
000 miles), the light will come on after the
ignition key is turned to the ªONº 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 ªOFFº position with the odometer
reading shown. (For details, see ªOdometer and trip meterº on
page 48.)
2. Turn the ignition key to the ªONº position while holding down
the ªODO/TRIPº button.
Hold down the button for at least 5 seconds. The odometer
indicates ª000000º and the light goes off.
If the system fails to reset, the system will revert to the state
before resetting operation. In this case, return to step 1 and try
again.

3. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the wheel nuts counterclockwise to loosen them. To
get maximum leverage, fit the wrench to the nut so that
the handle is on the right side, as shown above. Grab the
wrench near the end of the handle and pull up on the
handle. Be careful that the wrench does not slip off the
nut.
Do not remove the nuts yet ± just unscrew them about
one±half turn.
CAUTION
Never use oil or grease on the bolts or nuts. The
nuts may loosen and the wheels may fall off, which
could cause a serious accident.

4. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid
surface.
