Maintenance and care
Rotate the tires in the order shown.
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
When rotating front and rear tires which
have different tire inflation pressures,
do not fail to initialize the tire pressure
warning system afte r tire rotation.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a warning light.
( P. 4 7 5 )
■Routine tire inflation pressure
checks
The tire pressure warning system does
not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pres-
sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure warning system may not operate properly.
• If non-genuine Toyota wheels are
used. • A tire has been replaced with a tire
that is not an OE (Original Equipment)
tire. • A tire has been replaced with a tire
that is not of the specified size.
• Tire chains, etc. are equipped. • An auxiliary-supported run-flat tire is
equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the
vehicle, particularly around the wheels
NOTICE
●Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire
and wheel damage.
■If tire inflation pressure of each
tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
■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 addi-
tion, driving on rough roads may cause damage to the tires them-
selves, as well as the vehicle’s
wheels and body.

or wheel housings.
• If the tire inflation pressure is extremely higher than the specified
level.
• If tires not equipped with tire pressure warning valves and transmitters are
used.
• If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning
computer.
●Performance may be affected in the
following situations. • Near a TV tower, electric power plant,
gas station, radio station, large dis-
play, airport or other facility that gen- erates strong radio waves or electrical
noise.
• When carrying a portable radio, cellu- lar phone, cordless phone or other
wireless communication device.
●When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines
rapidly for example when a tire has burst, the warning may not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning system will change in accordance with
driving conditions. For this reason, the
system may give a warning even if the tire pressure does not reach a low
enough level, or if the pressure is higher
than the pressure th at was adjusted to when the system was initialized.
