Maintenance and care
■ 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 refilling, have it checked by your Lexus 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 and has not been driven for
more than 1 mile or 1.5 km, 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 pressures
that are even just a few pounds off can degrade ride and handling.
● Do not bleed or reduce tire inflation pressure after driving. It is normal for the
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.
