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.
It is difficult to judge if a tire is properly inflated based only on its appearance.
●
It is normal for the tire inflation pressure to be higher after driving as heat is generated
in the tire. Do not reduce tire inflation pressure after driving.
●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.
