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.
