Replacing components

Using the M Mobility System

To repair a flat tire with the M Mobility System,

proceed as follows:

> Fill the sealant, refer to page 132.

> Distribute the sealant, refer to page 132.

> Produce the tire inflation pressure, refer to

page 132.

Filling the sealant

Strictly follow the specified sequence,

otherwise the sealant may escape under

high pressure.<

1. Shake the sealant bottle.

2. Screw connection hose 9 onto the connec-

tor of the sealant bottle.

3. Ensure that screw 8 on the pressure gauge

is closed.

4. Unscrew the dust cap from the valve of the

defective wheel and screw filling hose 2 of

the sealant bottle onto the valve.

5. Insert the sealant bottle into the housing of

the compressor so that the bottle is upright.

6. Ensure that the compressor is switched off,

position 0.

7. Insert connector 3 into the cigarette lighter

socket in the interior of the vehicle, refer to

page 90.

8. With the ignition switched on:

Switch on the compressor and let it run for

approx. 3 minutes to fill the sealant. The

inflation pressure of the tire after filling is

unimportant.

9. Switch off the compressor.

10. Detach the hoses from the sealant bottle

connector and from the tire valve.

Return the M Mobility System to its storage

location in the vehicle.

Distributing the sealant

Immediately drive approx. 2 miles/3 km to

evenly distribute the sealant in the tire.

Do not exceed a speed of 35 mph/

60 km/h. If possible, do not fall below a

speed of 12 mph/20 km/h.<

Producing the tire inflation pressure

1. After driving approx. 2 miles/3 km, stop at a

suitable location.

2. Connect connection hose 9 of the com-

pressor directly to the tire valve.

3. Insert connector 3 into the cigarette lighter

socket in the interior of the vehicle.

4. Adjust the tire inflation pressure to 29 psi/

200 kPa. With the ignition switched on, pro-

ceed as follows:

> To increase the inflation pressure:

Switch on the compressor, position I. To

check the current inflation pressure set-

ting, briefly switch off the compressor.

Do not let the compressor run for

more than 10 minutes, otherwise the

device will overheat and may be dam-

aged.<

> To reduce the inflation pressure: turn

screw 8 on the pressure gauge.

If the inflation pressure is not maintained,

drive the vehicle a second time, refer to

Distributing the sealant. Then repeat steps 1 to

4.

Use of the M Mobility System may be ineffec-

tual for tire damage larger than approx. 0.16 in/

4 mm. Please contact the nearest BMW center,

refer to page 135, or a workshop that works

according to BMW repair procedures with cor-

respondingly trained personnel if the tire can-

not be made roadworthy with the M Mobility

System.<

The tire inflation pressure must be at least

29 psi/200 kPa. If it is not, do not continue

driving.<
