When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
Tire life
Any tires over 6 years old must be checked by a qualified technician even if
they have seldom or never been used or damage is not obvious.
If the tread depth wears down to 4 mm (0.16 in.) or more on snow tires
The effectiveness of snow tires is lost.
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 handling 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.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.

Maintenance and care
iQ_WE_74014E
NOTICE
Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
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.

Tire inflation pressure
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 refilling, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
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 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
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.
Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 455)

Maintenance and care

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
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or moisture 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
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 inset
*.
Replacement wheels are available at any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
*: Conventionally referred to as “offset”.
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 wrenches designed for use
with your aluminum wheels.
When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
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.

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 tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
When installing the wheel nuts
Be sure to install the wheel nuts with the tapered end facing inward.

Cleaning method
If the filter is dirty, clean by
blowing compressed air
through the filter as shown in
the illustration.
Hold the air gun 5 cm (2 in.)
from the filter and blow for
approximately 2 minutes at
500 kPa (5.0 kgf/cm
2 or bar, 72
psi).
If it is not available, have the
filter cleaned by any authorized
Toyota dealer or repairer, or
another duly qualified and
equipped professional.
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.
