Maintenance and care
CAUTION
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.
●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 compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
■When working near the cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the cooling fan may automatically start to run if
the air conditioning is on and/or the coolant temperature is high.
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han-
dling characteristics, which may lead to an accident resulting in death or
serious injury.
●Do not mix tires of different makes, models or tread patterns. Also, do
not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and winter tires.
NOTICE
■Repairing or replacing tires, wheels and tire pressure warning
valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning 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.
■If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
Air conditioning filter
The air conditioning filter must be cleaned or changed regularly to
maintain air conditioning efficiency.
■Removal method
Turn the engine switch off.
Open the glove box.
Slide off the damper.
Push in each side of the glove
box to disconnect the claws.

320 4-3. Do-it-yourself maintenance
Remove the filter case.
■Cleaning method
If the filter is dirty, clean by
blowing compressed air
through the filter from the
downward side.
Hold the air gun 2 in. (5 cm)
from the filter and blow for
approximately 2 minutes at
72 psi (500 kPa, 5.0 kgf/cm
2
or bar).
If it is not available, have
the filter cleaned by your
Toyota dealer.
■Replacement method
Remove the air conditioning
filter and replace it with a new
one.
The“UP” marks shown on the
filter should be pointing up.

Maintenance and care
■Checking interval
Inspect, clean and replace the air conditioning filter according to the mainte-
nance schedule. In dusty areas or areas with heavy traffic flow, more fre-
quent cleaning or early replacement may be required. (For scheduled
maintenance information, please refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.)
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
■To prevent damage to the system
●When using the air conditioning system, make sure that a filter is always
installed.
●When cleaning the filter, do not clean the filter with water.
