    Please see the chapter "WHEEL BOLTS" on page 226.
  2. Insert wheel bolts and tighten by hand.
  3. Remove assembly aids, screw in remaining wheel bolts.
    Initially tighten bolts only slightly in diagonally opposite sequence so that the wheel is centred.
  4. Inflate the tire if necessary.
    Please see the chapter "TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)" on page 267.
  5. Lower the car fully and remove the jack.
  6. Tighten wheel bolts in diagonally opposite sequence.

Immediately after changing a wheel, use a torque wrench to check the prescribed tightening torque (96 ftlb./130 Nm).

Note on operation for vehicles with Tire Pressure Monitoring

  • On vehicles with Tire Pressure Monitoring, the settings on the on-board computer must be updated after the wheel change.
  • Please see the chapter "TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)" on page 267.

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.

Note on operation

  • 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.


  1. 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.
    Please see the chapter "TIRE PRESSURE FOR COLD TIRES (68 °F/ 20 °C)" on page 267.
  2. Remove the pressure gage.
  • Please see the chapter "TPM TIRE PRESSURE MONITORING" on page 151.
