■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 restriction. Snow tires
should be installed on all wheels. ( P. 173)
■Initializing the tire pressure warning system
Initialize the tires with the tire inflation pressure adjusted to the specified
level.

■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire in flation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■When the initialization of the tire pressure warning system has
failed
Initialization can be completed in a few minutes. However, in the follow-
ing cases, the settings have not b een recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
●When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not flash 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving 20 minutes.
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.

CAUTION
■Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately
if a tire bursts or if sudden air leakage occurs.
■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 han-
dling characteristics, which may le ad to fatal or injury accidents.
●Do not mix tires of different makes, models, tread patterns or tread-
wear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix 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.
■When initializing the tire pressure warning system
Do not push 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 cor-
rectly.
●When replacing tires, make sure also to replace the tire pressure
warning valve and transmitter grommets.
■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 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.

■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. 376)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re sult 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. 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.
