Maintenance and Care
Tires
Inspect all tire pressures monthly (including the spare) when the tires
are cold. Maintain recommended pressures for the best ride, han-
dling, and minimum tire wear.
Refer to the spec ification charts
(→P. 5 6 0).
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.
For reasons of proper performance, safety, and better fuel econ-
omy, always maintain recommended tire inflation pressures and
stay within the recommended load limits and weight distribu-
tion.
WARNING
■Using Different Tire Types
Driving your vehicle with different ty pes of tires is dangerous. It could
cause poor handling and poor braking; leading to loss of control.
Except for the limited use of the temporary spare tire, use only the same
type tires (radial, bias-belted, bias-type) on all four wheels.
■Using Wrong-Sized Tires
Using any other tire size than what is specified for the vehicle (→P. 560)
is dangerous. It could seriously affect ride, handling, ground clearance,
tire clearance, and speedometer ca libration. This could cause you to
have an accident. Use only tires that are the correct size specified for
the vehicle.

NOTICE
●When using the temporary spare tire, driving stability may decrease
compared to when using only the conventional tire. Drive carefully.
●To avoid damage to the temporary s pare tire or to the vehicle, observe
the following precautions:
• Do not exceed 50 mph (80 km/h).
• Avoid driving over obstacles. Also, do not drive through an auto- matic car wash. This tire’s diameter is smaller than a conventional
tire, so the ground clearance is reduced.
• Do not use a tire chain on this ti re because it will not fit properly.
• Do not use your temporary spare tire on any other vehicle, it has been designed only for your Toyota.
• Use only one temporary spare tire on your vehicle at the same time.
