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.
