.
nTire inflation pressure check interval
You should check tire inflation pressu
re every 2 weeks, or at least once a
month.
Do not forget to check the spare.
nInspection and adjustment procedure
Ti r e va l v e
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the graduations of the gauge.
If the tire inflation pressure is not within the recommended
levels, adjust tire pressure.
If you add too much air, pres
s the center of the valve to
lower.
After completing the tire inflation pressure measurement
and adjustment, apply soapy water to the valve and check
for leakage.
Reinstall the tire valve cap.

Maintenance and care
nEffects of incorrect tire inflation pressure
Driving with incorrect ti
re inflation pressure may result in the following:
lReduced fuel efficiency
lReduced driving comfort and tire life
lReduced safety
lDamage to the drive train
If a tire needs frequent re
filling, have it checked by your Toyota dealer.
nInstructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
lCheck only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or
1.5 km, you will get an accurate cold
tire inflation pressure reading.
lAlways use a tire pressure gauge.
The appearance of the tire can be mi
sleading. In addition, tire infla−
tion pressures that are even just a few pounds off can degrade ride
and handling.
lDo not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.
lNever exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

CAUTION
n Proper 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
n When 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.

Maintenance and care
Wheels
If a wheel is bent, cracked or heavily corroded, it should be
replaced.
Otherwise, the tire may separate from the wheel or cause loss of
handling control.
nWheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and offset.
Replacement wheels are available at your Toyota dealer.
Toyota does not recommend using:
lWheels of different sizes or types
lUsed wheels
l
Bent wheels that have been straightened
n
Aluminum wheel precautions
l
Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
l
When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
lBe careful not to damage the aluminum wheels when using
tire chains.
lUse only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

406 4−3. Do−it−yourself maintenance
nWhen replacing wheels
The wheels of your Toyota are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advanced warning in the event of a loss in tire inflation pressure. Whenever
wheels are replaced, the tire pressure warning valves and transmitters must
be installed. (
P. 392)
CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in the
Owner ’s Manual, as this may result in loss of handling control.
lNever use an inner tube in a leaking wheel which is designed for a tube−
less tire. Doing so may result in an accident, causing death or serious
injury.
NOTICE
nReplacing tire pressure warning valves and transmitters
lBecause tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by your Toyota
dealer or other qualified service shop. In addition, make sure to purchase
your tire pressure warning valves and transmitters at your Toyota dealer.
l
Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with
non−genuine wheels.

Maintenance and care
Air conditioning filter
The air conditioning filter must be changed regularly to maintain air
conditioning efficiency.
nRemoval method

mode and switch to recirculated air mode, then turn the
“ENGINE START STOP” switch off.
Open the glove box and
remove the partition.
Remove the filter cover.

408 4−3. Do−it−yourself maintenance
Remove the filter case.
Remove the air conditioning
filter and replace it with a new
one.
The “UP” marks shown on
the filter should be pointing up.
nCleaning 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.

Maintenance and care
nChanging interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, read the “Sched−
uled Maintenance Guide”, “Owner ’s Manual Supplement”.)
nIf air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
nTo prevent damage to the system
lWhen using the air conditioning system, make sure that a filter is always
installed.
l
When cleaning the filter, do not clean the filter with water.
