All tire pressures (including the spare) should be checked when the tires are cold. “Cold Tires” means the vehicle has not been driven for at least three hours or driven less than 1.6 km (one mile).
Recommended pressures must be maintained for the best ride, top vehicle handling, and minimum tire wear.
For recommended inflation pressure refer to “Tire and wheels” in chapter 8.

All specifications (sizes and pressures) can be found on a label attached to the driver’s side center pillar.
WARNING - Checking the tire inflation pressure
Inflate your tires consistent with the instructions provided in this manual.
Regularly check the tire inflation pressure, and correct it as needed: at least twice a month and before a long trip.
If you fail to observe this precaution, you may be driving on tires with incorrect tire pressures, a condition that may not only compromise your vehicle's driving stability, but also lead to tire damage and the risk of an accident.
This risk is much higher on hot days and when driving for long periods at high speeds.
