Maintenance and care WARNING
The engine compartment contains many mechan isms and fluids that may move suddenly,
become hot, or become electrically energize d. To avoid death or serious injury, observe
the following precautions: ■
When working on the engine compartment ●
Keep hands, clothing and tools away from the moving fan and engine drive belt.●
Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driving
as they may be hot. Oil and other fluids may also be hot. ●
Do not leave anything that may burn easily, such as paper or rags, in the engine com-
partment. ●
Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel and
battery fumes are flammable. ●
Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid. ■
When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the
electric cooling fans may auto matically start to run if the air conditioning is on and/or
the coolant temperature is high. (  P. 481) ■
When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports. ■
Safety glasses
Wear safety glasses to prevent flying or falling material, flui d spray, etc. from getting in
your eyes.
NOTICE ■
If you remove the air cleaner filter
Driving with the air cleaner f ilter removed may cause excessive engine wear due to dirt
in the air.

When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured:  P. 535
If none of the tires are punctured:
Turn the engine switch off then turn it to IGNITION ON mode. Check if the tire pressure
warning light comes on or flashes. 
If the tire pressure warning light comes on
After the temperature of the tires has lowere d sufficiently, check the inflation pressure
of each tire and adjust th em to the specified level.
If the warning light does not turn off even after several minutes have elapsed, check
that the inflation pressure of each tire is at the specified level an d perform initialization.
(  P. 489)
If the warning light does not turn off even after several minutes have elapsed, have the
vehicle inspected by your Lexus dealer immediately. 
If the tire pressure wa rning light flashes for 1 minute then stay on
There may be a malfunction in the tire pressure warnin g system. Have the vehicle
inspected by your Lexus dealer immediately. ■
The tire pressure warning light ma y turn on due to natural causes
The tire pressure warning light may turn on du e to natural causes such as natural air leaks
or tire inflation pressure changes caused by temperature. In this case, adjusting the tire
inflation pressure will turn off the warning light (after a few minutes).■
When a tire is replaced with a spare tire
The spare tire is also equipped with the tire pressure warning valve and transmitter. The
tire pressure warning light will tu rn on if the tire inflation pressu re of the spare tire is low. If
a tire goes flat, even though the flat tire is replaced with the spare tire, the tire pressure
warning light does not turn off. Replace the spare tire with the repaired tire and adjust the
proper tire inflation pressure. The tire pressu re warning light will tu rn off after a few min-
utes. ■
Conditions that the tire pressure wa rning system may not function properly
 P. 492 ■
Changing the engine oil
Make sure to reset oil change system ■
Warning buzzer
In some cases, the buzzer ma y not be heard due to being in a noisy location or audio
sound. 1
