BMW 3: Mobility System

Concept

With the Mobility System, minor tire damage can be sealed temporarily to enable continued travel.

To accomplish this, sealant is pumped into the tires, which seals the damage from the inside.

General information

• Follow the instructions on using the Mobility System found on the compressor and sealant container.
• Use of the Mobility System may be ineffective if the tire puncture measures approx. 1/8 inches/4 mm or more.
• Contact a dealer's service center or another qualified service center or repair shop if the tire cannot be made drivable.
• Do not remove foreign bodies that have penetrated the tire. Only remove foreign objects if they are visibly protruding from the tire.
• Pull the speed limit sticker off the sealant container and apply it to the steering wheel.
• The use of a sealant can damage the TPM wheel electronics. In this case, have the electronics checked and replaced at the next opportunity.
• The compressor can be used to check the tire inflation pressure.

Overview

Storage

The Mobility System is located in a bag in the left storage compartment of the cargo area. Release the tensioning strap to remove.

Sealant container

• Filling hose, arrow 2.

Observe use-by date on the sealant container.

Compressor

1. Sealant container unlocking
2. Sealant container holder
3. Tire pressure gage
4. Reduce tire inflation pressure button
5. On/off switch
6. Compressor
7. Connector/cable for socket
8. Connection hose

Safety measures

• Park the vehicle as far away as possible from passing traffic and on solid ground.
• Switch on the hazard warning system.
• Secure the vehicle against rolling away by setting the parking brake.
• Turn the steering wheel until the front wheels are in the straight-ahead position and engage the steering wheel lock.
• Have all vehicle occupants get out of the vehicle and ensure that they remain outside the immediate area in a safe place, such as behind a guardrail.
• If necessary, set up a warning triangle at an appropriate distance.

Filling the tire with sealant

Safety information

DANGER If the exhaust pipe is blocked or ventilation is insufficient, harmful exhaust gases can enter into the vehicle. The exhaust gases contain pollutants which are colorless and odorless. In enclosed areas, exhaust gases can also accumulate outside of the vehicle. There is danger to life. Keep the exhaust pipe free and ensure sufficient ventilation.

NOTICE The compressor can overheat during extended operation. There is a risk of damage to property.

Do not run the compressor for more than 10 minutes.

Filling

1. Shake the sealant container.

2. Pull filling hose completely out of the cover of the sealant container. Do not kink the hose.

3. Slide the sealant container into the holder on the compressor housing, ensuring that it engages audibly.

4. Screw the filling hose of the sealant container onto the tire valve of the nonworking wheel.

5. With the compressor switched off, insert the plug into the power socket inside the vehicle.

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

Let the compressor run for max. 10 minutes to fill the tire with sealant and achieve a tire inflation pressure of approx. 2.0 bar.

While the tire is being filled with sealant, the tire inflation pressure may sporadically reach approx. 5 bar. Do not switch off the compressor at this point.

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.

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

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

If a tire inflation pressure of at least 2 bar cannot be reached, contact your dealer's service center or another qualified service center or repair shop.

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

6. Unscrew the connection hose of the compressor from the tire valve.

7. Pull the connector out of the power socket inside the vehicle.

8. 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.

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

4. 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.

5. Unscrew the connection hose of the compressor from the tire valve.

6. Pull the connector out of the power socket inside the vehicle.

7. 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 run-flat tires.

Reset the Tire Pressure Monitor TPM.

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