■
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 pressure
that is even just a few pounds off can degrade ride and handling.
Do not reduce tire inflation pressure after driving. It is normal for tire inflation

Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
