Maintenance and care
WARNING
The engine compartment contains many mechanisms 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. 483)
■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, fluid spray, etc. from getting in
your eyes.

■How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the engine switch to off.
Initialization cannot be performed while the vehicle is moved.
Adjust the tire inflation pressure to th e specified cold tire inflation pressure
level. ( P. 571)
Make sure to adjust the tire pressure to the specified cold tire inflation pressure
level. The tire pressure warning system will operate based on this pressure level.
Turn the engine switch to IGNITION ON mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.
“--” will be displayed for inflation
pressure of each tire on the multi-
information display while the tire
pressure warning system determines
the position of each tire.
When position of each tire is determined, the inflation pressure of each tire will be
displayed on the mult i-information display.
Drive the vehicle at approximately 25 mph (40 km/h) or more for approx-
imately 10 minutes.
When initialization is comple te, the inflation pressure of each tire will be displayed
on the multi-information display.
Initialization will take long er than approximately 10 minutes if the vehicle is
stopped for a long time, su ch as at traffic signals.
◆Registering ID codes
The tire pressure warning valve and tran smitter is equipped with a unique ID
code. When replacing a tire pressure warning valve and transmitter, it is nec-
essary to register the ID code of tire pressure warning valve and transmitter.
Have the ID code registered by your Lexus dealer.

■When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: P. 537
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 and perform initialization.
(  P. 491)
If the tire pressure wa rning light blinks for 1 minute then stay on
There may be a malfunction in the tire pressure warning system. Have the vehicle
inspected by your Lexus dealer immediately.
■The tire pressure warning light may 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 pressure 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 turn off after a few min-
utes.
■Conditions that the tire pressure wa rning system may not function properly
 P. 494
■Changing the engine oil
Make sure to reset oil change system
■Warning buzzer
