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.
