9 Connecting hose for connecting compres-

sor and sealant bottle or compressor and

wheel

Connector, cable and connecting hose are

attached to the bottom of the compressor.

Using the M Mobility System

To repair a flat tire with the M Mobility System,

proceed as follows:

> Fill sealant into wheel

> Distribute sealant

> Restore tire inflation pressure

Filling sealant into wheel

Strictly adhere to the specified order, oth-

erwise highly pressurized sealant could

escape.<

1. Shake sealant bottle.

2. Screw hose 9 onto connection of sealant

bottle.

3. Unscrew and remove dust cap from valve of

defective wheel and screw filler hose 2 of

sealant bottle onto valve.

4. Insert sealant bottle on compressor hous-

ing so that the bottle is in an upright posi-

tion.

5. Make sure that the device is switched off,

position 0.

6. Insert connector 3 into cigarette lighter

socket inside the vehicle.

7. With the ignition switched on:

Switch on the device and allow it to run for

approx. 3 minutes to fill the wheel with seal-

ant. It is not important what inflation pres-

sure the tire has after this.

8. Switch off device.

9. Remove connecting hoses from connection

of sealant bottle and tire valve.

Stow the M Mobility System in the vehicle

again.

Distributing sealant

Immediately drive approx. 2 miles/3 km so that

the sealant is evenly distributed in the tire.

Do not exceed a speed of 35 mph or

60 km/h. Do not drive slower than 12 mph

or 20 km/h if possible.<

Restoring tire inflation pressure

1. After approx. 2 miles/3 km, pull over at a

suitable location.

2. Screw compressor hose 9 directly onto tire

valve.

3. Insert connector 3 into cigarette lighter

socket inside the vehicle.

4. Correct tire inflation pressure to 29 psi/

200 kPa. With the ignition switched on:

> To increase inflation pressure: switch on

the compressor, position I. To check the

current pressure setting, briefly switch

off the device.

Do not allow the compressor to run

for more than 10 minutes, otherwise

the device will overheat and may be dam-

aged.<

> To reduce inflation pressure: press but-

ton 8.

If the inflation pressure is not maintained,

drive the vehicle again, refer to Distribut-

ing sealant. Then repeat steps 1 to 4 once.

Using the M Mobility System can be ineffective

with tire punctures larger than approx. 1/6 in/

4 mm. Please contact the nearest BMW center

or a workshop that works according to BMW

repair procedures with correspondingly trained

personnel if the tire cannot be made ready for

driving with the M Mobility System.<

The tire inflation pressure must be at least

29 psi/200 kPa. Otherwise do not con-

tinue driving.<
