Maintenance and care
Tire inflation pressure check interval
You should check tire pressure 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 efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent re
filling, have it checked by your Toyota dealer.
 Inspection 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 inflate the tire.
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.

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 not 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.
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.
Do not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.
CAUTION
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.
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards

Maintenance and care
NOTICE
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.

Wheels
When replacing wheels
The wheels of your Toyota are equipped with sensors that allow the tire
pressure warning system sensors to provide advanced warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced,
the tire pressure warning valve and transmitter must be switched over
from the old wheels. (
P. 288) 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.
 Wheel 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:

Wheels of different sizes or types
Used wheels

Bent wheels that have been straightened

Aluminum wheel precautions (if equipped)
Use only Toyota wheel nuts and wrench designed for use with
your aluminum wheels.
 When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).

Be careful not to damage the aluminum wheels when using
tire chains.
 Use only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Maintenance and care
CAUTION
When replacing wheels
Do 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.
Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri−
ous injury.
NOTICE
Replacing tire pressure warning valves and transmitters
Because tire repair or replacement may affect the tire pressure warn−
ing valves and transmitters, make su re 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.
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
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.

 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.
