NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not hand led
correctly.
●Make sure to install the tire val ve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves a nd the
tire pressure warning valves could be bound.
●When replacing tire valve caps, do not use tire valve caps othe r than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
When a tire is repaired with liqui d sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replac e the tire pressure warning valve and
transmitter when replacing the tire. ( P. 4 7 9 )
■Driving on rough roads
Take particular care when drivi ng on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the t ires. In addition, driving on ro ugh roads
may cause damage to the tires themselves, as well as the vehicl e’s
wheels and body.
■If tire inflation pressure of e ach tire becomes low while drivi ng
Do not continue driving, or your t ires and/or wheels may be ruined.

Maintenance and care
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has no t been
driven for more than 1 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based o nly on its appear-
ance.
●It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pre ssure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehi cle is
balanced.
WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly in flated, the following conditions may occur
which could lead to an accident r esulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overh eated tires
●Air leaking from between tire and wheel
●Wheel deformation and/ or tire damage
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp ed ges in the road, etc.)
NOTICE
■When inspecting and adjusti ng tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed , dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressu re.

Air conditioning filter
Turn the engine switch IGNITION ON mode and switch to recircu-
lated air mode, then turn the engine switch off.
Open the glove box and remo ve the separate tray. (P. 413)
Remove the filter cover.
Remove the filter case.
If the filter is dirty, clean by blow-
ing compressed air through the fil-
ter from the downward side.
Hold the air gun 2 in. (5 cm) from
the filter and blow for approxi-
mately 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.
The air conditioning filter must be cleaned or changed regularly
to maintain air condi tioning efficiency.

If you think something is wrong
●Fluid leaks un der the vehicle
(Water dripping from the air conditioning a fter use is normal.)
● Flat-looking tires or uneven tire wear
● Engine coolant temperature gauge needle continually points high er
than normal
● Engine oil pressure gauge contin ually points lower than normal.
● Voltmeter continually points higher or lower than normal.
● Changes in exhaust sound
● Excessive tire squeal when cornering
● Strange noises related to the suspension system
● Pinging or other noises related to the engine
● Engine missing, stumb ling or running roughly
● Appreciable loss of power
● Vehicle pulls heavily to one side when braking
● Vehicle pulls heavily to one s ide when driving on a level road
● Loss of brake effectiveness, spongy feeling, pedal almost touch es
the floor
If you notice any of the followi ng symptoms, your vehicle proba -
bly needs adjustment or repair. Contact your Toyota dealer as
soon as possible.

When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured:
P. 539
If none of the tires are punctured:
Turn the engine switch off then turn it to IGNITION ON mode. Ch eck if the
tire pressure warning light comes on or flashes.
If the tire pressure wa rning light comes on
After the temperature of the tires has lowered sufficiently, ch eck the
inflation pressure of each tire and adjust them to the specifie d level.
If the warning light does not turn off even after several minut es have
elapsed, check that the inflation pressure of each tire is at t he specified
level and perform initialization. (P. 4 7 9 )
If the warning light does not turn off even after several minut es have
elapsed, have the vehicle inspected by your Toyota dealer immed iately.
If the tire pressure warning light flashes for 1 minute then st ay on
There may be a malfunction in the tire pressure warning system. Have
the vehicle inspected by you r Toyota dealer immediately.
■The tire pressure warning light may turn on due to natural caus es
The tire pressure warning light may turn on due to natural caus es such as
natural air leaks or tire inflation pressure changes caused by tempera-
ture. In this case, adjusting the tire inflation pressure will turn off the warn-
ing light (after a few minutes).
■When a tire is replace d with a spare tire
The spare tire is also equipped with the tire pressure warning valve and
transmitter. The tire pressure warning light will turn on if the tire inflation
pressure of the spare tire is low. If a tire goes flat, even th ough 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 adj ust the proper
tire inflation pressure. The tire pressure warning light will t urn off after a
few minutes.
■Conditions that the tire pressure warning system may not functi on
properly
