Maintenance and care
■Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restrictions. Snow tires
should be installed on all wheels. ( P. 173)
■Initializing the tire pressure warning system
Initialize the tire pressure warning sy stem with the tire inflation pressure
adjusted to the specified level.

Maintenance and care
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 ma kes, 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.
■When initializing the tire pressure warning system
Do not press the tire pressure warnin g reset switch without first adjusting
the tire inflation pressure to the spec ified level. Otherwise, the tire pres-
sure warning light may not come on ev en if the tire inflation pressure is
low, or it may come on when the tire inflation pressure is actually normal.

NOTICE
■Repairing or replacing tires, wheels and tire pressure warning
valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire air 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.

Maintenance and care
Wheels
■When 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. 353)
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 wheel that have been straightened
■ Aluminum wheel precautions
●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 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine bal ance weights or equivalent and
use 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
tubeless tire. Doing so may result in an accident, causing serious
injury or death.
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.
