once every two weeks. (P. 607)

Reduced driving comfort and poor handling

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 reading.
● Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
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.
