Maintenance and care
NOTICE
nRepairing 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.
nTo avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
nDriving 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.
nIf tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
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 resu lting 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 reinstall the tire valve caps.
Without the valve caps, dirt or mo isture could get into the valve and
cause air leakage, which could result in an accident. If the caps have
been lost, replace them as soon as possible.

4-3. Do-it-yourself maintenance
Air conditioning filter (if equipped)
The air conditioning filter must be changed regularly to maintain air
conditioning efficiency.
n 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.

254 4-3. Do-it-yourself maintenance
nChecking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas wit h heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to
the “Scheduled Maintenance Guide” or “Owner’s Manual Supplement”.)
n If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
nWhen using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.

When trouble arises

5-2. Steps to take in an emergency
The engine has cooled down sufficiently.
Low engine coolant temperature indicator comes on.
Check the engine coolant level.
Look for obvious coolant leaks
from the radiator, hoses and
under the vehicle.
Note that water draining from the air conditioning is normal if it has
been used.
Add engine coolant if required.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( →P. 330)
Have the vehicle checked at your nearest Toyota dealer as soon as
possible.
