 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 any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
 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 pres-
sure 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 inflation
pressure to be higher after driving.
 Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
Tire inflation pressure
Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. (
