Note on operation for vehicles with Tire Pressure Monitoring

• On vehicles with Tire Pressure Monitoring, the settings on the multi-function display must be updated after the wheel change.
• Please see the chapter "TIRE PRESSURE MENU (TIRE PRESSURE MONITORING, TPM)" on page 104.

Checking tire pressure with a pressure gage

1. Remove the valve stem cap from the tire.
2. Press the pressure gage onto the valve stem.

Information

• Do not press too hard or force the valve stem sideways, or air will escape.
  If the sound of air escaping from the tire is heard, reposition the pressure gage.

3. Read the tire pressure on the gage stem and compare it to the permissble tire pressure. This information can be found on the tire pressure plate or in the chapter Technical Data.
4. Remove the pressure gage.
