tire inflation pressure is actually normal.

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 or has not been driven for
more than 1.5 km or 1 mile, you will get an
accurate cold tire inflation pressure read-
ing.
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 gen-
erated in the tire. Do not reduce tire infla-
tion pressure after driving.
Passengers and luggage weight should
●
be placed so that the vehicle is balanced.
