Maintenance and Care
Also, inspect them for uneven wear and damage. Abnormal wear is
usually caused by one or a combination of the following:• Incorrect tire pressure
• Improper wheel alignment
• Out-of-balance wheel
• Severe braking
After rotation, inflate all tire pressures to specification (
→P. 558) and
inspect the lug nu ts for tightness.
With tire pressure monitoring system:
After adjusting the tire pressure, init ialization of the tire pressure mon-
itoring system is necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on P. 221.
WARNING
■Rotate tires periodically
Irregular tire wear is dangerous. To equalize tire wear and extend tire
life, Toyota recommends that tire rotation is carried out at the same
interval as tire inspection.
For scheduled maintenance information, please refer to the “Owner’s
Manual Supplement/Scheduled Maintenance Guide”.
NOTICE
Rotate unidirectional tires and radial tires that have an asymmetrical
tread pattern or studs only from front to rear, not from side to side. Tire
performance will be reduced if rotated from side to side.

If a tire wears evenly, a wear indicator will appear as a solid band
across the tread.
Replace the tire when this happens.New tread

You should replace the tire before the band crosses the entire tread.
With tire pressure monitoring system:
After adjusting the tire pressure, init ialization of the tire pressure mon-
itoring system is necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on P. 221.
Tires degrade over time, even when they are not being used on the road.
It is recommended that tires generally be replaced when they are 6 years
or older. Heat caused by hot climates or frequent high loading conditions
can accelerate the aging process. You should replace the spare tire when
you replace the other road tires due to the aging of the spare tire. The
period in which the tire was manufactured (both week and year) is indi-
cated by a 4-digit number.
Refer to Tire Labeling on P. 530.

WARNING
■Always use tires that are in good condition
Driving with worn tires is dangerous. Reduced braking, steering, and
traction could result in an accident.
■Replace all four tires at the same time
Replacing just one tire is dangerous. It could cause poor handling and
poor braking resulting in loss of vehicle control. Toyota strongly recom-
mends that you replace all four tires at the same time. If you replace
only two tires, the new tires should be installed on the rear of the vehi-
cle.

Maintenance and Care
Inspect the temporary spare tire at least monthly to make sure it is
properly inflated and stored.
The temporary spare tire is easier to handle because of its construc-
tion which is lighter and smaller than a conventional tire. This tire
should be used only for an emergen cy and only for a short distance.
Use the temporary spare tire only until the conventional tire is
repaired, which should be as soon as possible.
Refer to Tires on P. 558.
●The temporary spare tire condition gradually deteriorates even if it has
not been used.
●Tires degrade over time, even when they are not being used on the
road. It is recommended that tires gen erally be replaced when they are
6 years or older. Heat caused by ho t climates or frequent high loading
conditions can accelerate the aging process. You should replace the
spare tire when you replace the other road tires due to the aging of the
spare tire. The period in which the tire was manufactured (both week
and year) is indicated by a 4-digit number.
Refer to Tire Labeling on P. 530.
Proper tire balancing provides the best riding comfort and helps
reduce tread wear. Out-of-balance tires can cause vibration and
uneven wear, such as cupping and flat spots.
When replacing a wheel, make sure the new one is the same as the orig-
inal factory wheel in diameter, rim width, and offset (inset/outset).
For details, contact your Toyota dealer.
Temporary Spare Tire
NOTICE
●Do not use your temporary spare tire rim with a snow tire or a conven-
tional tire. Neither will properly fit and could damage both tire and rim.
●The temporary spare tire has a tread life of less than 3,000 miles
(5,000 km). The tread life may be shorter depending on driving condi-
tions.
●The temporary spare tire is for limited use, however, if the tread wear
solid-band indicator appears, replace the tire with the same type of
temporary spare (→P. 443).

WARNING
■Always use wheels of the correct size on your vehicle
Using a wrong-sized wheel is dangerous. Braking and handling could
be affected, leading to loss of control and an accident.
NOTICE
A wrong-sized wheel may adversely affect:
●Tire fit
●Wheel and bearing life
●Ground clearance
●Snow-chain clearance
●Speedometer calibration
●Headlight aim
●Bumper height
●Tire Pressure Monitoring System (if equipped)

WARNING
■Never touch the glass portion of a halogen bulb with your bare hands
and always wear eye protection when handling or working around the
bulbs
When a halogen bulb breaks, it is dangerous. These bulbs contain pressur-
ized gas. If one is broken, it will explode and serious injuries could be
caused by the flying glass.
If the glass portion is touched with bare hands, body oil could cause the
bulb to overheat and explode when lit.
■ Always keep halogen bulbs out of the reach of children
Playing with a halogen bulb is dangerous. Serious injuries could be caused
by dropping a halogen bulb or breaking it some other way.
NOTICE
When removing the lens or lamp unit using a flathead screwdriver, make
sure that the flathead screwdriver does not contact the interior terminal. If
the flathead screwdriver contacts the terminal, a short circuit may occur.
