Maintenance and care
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 any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer as the tire press ure warning
valves and transmitters may be damaged if not handled correctly .
● Make sure to install the tire valve 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 other than those
specified.
The cap may become stuck.
■ 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, r educing 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.
■ To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant i s used, contact
any authorized Toyota retailer or Toyota authorized repairer, o r any reliable
repairer or other qualified service shop as soon as possible. A fter use of liq-
uid sealant, make sure to replace the tire pressure warning val ve and trans-
mitter when repairing or replacing the tire. ( P. 616)
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be rui ned.

Tire inflation pressure
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in th e following:
● Reduced fuel economy
● Reduced driving comfort and poor handling
● Reduced tire life due to wear
● Reduced safety
● Damage to the drivetrain
If a tire needs frequent inflating, have it checked by any auth orized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r.
■ 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 or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold t ire 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 pressure af ter driving.
● Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
Make sure to maintain proper tire inflation pressure. Tire infl a-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. ( P. 7 7 4 )

Maintenance and care
WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following condition s may occur
which could lead to an accident resulting in death or serious i njury:
● Excessive wear
● Uneven wear
● Poor handling
● Possibility of blowouts resulting from overheated 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 edges in the road, etc.)
NOTICE
■ When inspecting and adjusting 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.

Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim wid th and
inset*.
Replacement wheels are available at any authorized Toyota retai ler or
Toyota authorized repairer, or any reliable repairer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● 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 plas-
tic or rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

Maintenance and care
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing valves
and transmitters (except for compact spare tire) that allow the tire pressure
warning system to provide advance warning in the event of a los s in tire infla-
tion pressure. Whenever wheels are replaced, tire pressure warning valves
and transmitters must be installed. ( P. 616)
WARNING
■When replacing wheels
● Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may resu lt in a 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 ends facing inward.
( P. 736) Installing the nuts with the tapered ends facing outward can
cause the wheel to break and eventually cause the wheel to come off
while driving, which could lead to an accident resulting in dea th or serious
injury.
● Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight ened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, caus ing an acci-
dent and resulting in death or serious injury. Remove any oil o r grease
from the wheel bolts or wheel nuts.
■ Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possi bly causing an
accident.

NOTICE
■Replacing tire pressure warning valves and transmitters
● Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by an y autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer
or other qualified service shop. In addition, make sure to purc hase your
tire pressure warning valves and transmitters at any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r.
● Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work prop erly with
non-genuine wheels.
