Tire inflation pressure
■ Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
● Reduced fuel efficiency
● Reduced driving comfort and tire life
● Reduced safety
● Damage to the drive train
If a tire needs frequent inflating, have it checked by your Toyota dealer.
■ Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
● Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
● Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressure that is even just a few pounds off can affect ride quality and
handling.
● Do not reduce tire inflation pressure after driving. It is normal for tire infla-
tion pressure to be higher after driving.
● Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
Make sure to maintain proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (→P. 441)
