BMW 7 Series: Mobility System- Checking and adjusting the tire inflation pressure

Checking

  1. Switch off the compressor.
  2.  Read the tire inflation pressure on the tire pressure gage.

To continue the trip, a tire inflation pressure of at least 2 bar must be reached.

Removing and stowing the sealant container

  1. Unscrew the filling hose of the sealant container from the tire valve.
  2.  Press the red unlocking device.
  3.  Remove the sealant container from the compressor.
  4. Wrap and store the sealant container in suitable material to avoid dirtying the cargo area.

Minimum tire inflation pressure is not reached

  1. Pull the connector out of the power socket inside the vehicle.
  2.  Drive 33 ft/10 m forward and back to distribute the sealant in the tire.
  3. Screw the connection hose of the compressor directly onto the tire valve stem.

Minimum tire inflation pressure is not reached


  1. Insert the connector into the power socket inside the vehicle.

Minimum tire inflation pressure is not reached


  1. With standby state switched on or the engine running, switch on the compressor.

    When the tire pressure does not reach at least 2 bar, contact a manufacturer service center or another qualified service center or repair shop.

    When a tire pressure of at least 2 bar is reached, see Minimum tire inflation pressure is reached.

  2.  Unscrew the connection hose of the compressor from the tire valve.
  3. Pull the connector out of the power socket inside the vehicle.
  4. Stow the Mobility System in the vehicle.

Minimum tire inflation pressure is reached

  1. Unscrew the connection hose of the compressor from the tire valve.
  2.  Pull the connector out of the power socket inside the vehicle.
  3. Stow the Mobility System in the vehicle.
  4. Immediately drive approx. 5 miles/10 km to ensure that the sealant is evenly distributed in the tire.

    Do not exceed a speed of 50 mph/80 km/h.

    If possible, do not drive at speeds less than 12 mph/20 km/h.

Adjustment

  1. Stop at a suitable location.
  2. Screw the connection hose of the compressor directly onto the tire valve stem.

Minimum tire inflation pressure is reached


  1. Insert the connector into the power socket inside the vehicle.

Minimum tire inflation pressure is reached


  1. Correct the tire inflation pressure to at least 2.0 bar:
  • Increase tire inflation pressure: with standby state switched on or the engine running, switch on the compressor.
  • Reduce tire inflation pressure: press the button on the compressor.
  1. Unscrew the connection hose of the compressor from the tire valve.
  2. Pull the connector out of the power socket inside the vehicle.
  3. Stow the Mobility System in the vehicle.

Continuing the trip

Do not exceed the maximum permissible speed of 50 mph/80 km/h.

Reinitialize the Flat Tire Monitor.

Reset the Tire Pressure Monitor again.

Replace the nonworking tire and the sealant container of the Mobility System promptly.
