complete when the tire pressure warn-
ing light turns off and the inflation pres -
sure of each tire is displayed on the
multi-information display.
■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres -
sure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it
checked by any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
■Instructions for checking tire infla -
tion 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.
It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the tire inflation pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pre ssure after driving.
●Passengers and luggage weight
Tire inflation pressure
Make sure to maintain the
proper tire inflation pressure.
Tire inflation pressure should
be checked at least once per
month. However, Toyota rec -
ommends that tire inflation
pressure be checked once
every two weeks. ( →P.624)
