cool air is ready to flow.
nUsing the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used for an extended
period.

Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
nWhen working on the engine compartment
lKeep hands, clothing and tools away from the moving fan and engine drive belt.
lBe careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
lDo not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
lDo not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
lBe extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
nWhen working near the electric cooling fan or radiator grille
Be sure the “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fan may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (→P. 4 7 2 )
nSafety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
nIf you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also a backfire could cause a fire in the engine compartment.

4-3. Do-it-yourself maintenance
NOTICE
nRepairing or replacing tires, wheels, tire pressure warning valves, transmitters
and tire valve caps
lWhen removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valves and
transmitter may be damaged if not handled correctly.
lWhen replacing tire valve caps, do not use tire valve caps other than those speci-
fied. The cap may become stuck.
nTo avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact your Lexus
dealer or other qualified service shop as soon as possible. Make sure to replace the
tire pressure warning valve and transmitter when replacing the tire. (→P. 4 7 9 )
nDriving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving on rough roads may cause damage to the
tires themselves, as well as the vehicle’s wheels and body.
nIf tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

4-3. Do-it-yourself maintenance
CAUTION
nProper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may occur
and result in an accident causing death or serious injury:
lExcessive wear
lUneven wear
lPoor handling
lPossibility of blowouts resulting from overheated tires
lPoor sealing of the tire bead
lWheel deformation and/or tire separation
lA greater possibility of tire damage from road hazards
NOTICE
nWhen inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and cause air leak-
age, which could result in an accident. If the caps are lost, replace them as soon as
possible.
