Checking the tire pressures
Important safety notes
WARNING
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.
Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.
Check the tire pressure at least once a month.
Only check and correct tire pressures when the tires are cold
Checking tire pressure manually
To determine and set the correct tire pressure, proceed as follows:
•► Remove the valve cap of the tire that is to be checked.
•► Press the tire pressure gauge securely onto the valve.
•► Read the tire pressure and compare it with the recommended value on the Tire and Loading Information placard on the B-pillar on the driver's side of your vehicle.
•► If necessary, increase the tire pressure to the recommended value.
•► If the tire pressure is too high, release air by pressing down the metal pin in the valve using the tip of a pen, for example. Then check the tire pressure again using the tire pressure gauge.
•► Screw the valve cap onto the valve.
•► Repeat these steps for the other tires.
