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 any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Make sure to maintain the 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. 550)
