WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
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.
ItemsParts and tools●Be careful not to touch the
engine, radiator, exhaust mani-
fold, 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 and
rags, in the engine compart-
ment.
●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 con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the engine switch is off.
With the engine switch in ON, the
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.416)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

Tire valve
Tire pressure gauge
1 Remove the tire valve cap. 2
Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 If the tire inflation pressure is
not at the recommended
level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back
on.
■Tire inflation pressure check
interval
You should check tire inflation pres-
sure every two weeks, or at least
once a month. Do not forget to
check the spare.
■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation
pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked by your Toyota
dealer.
