32 Corresponding information on using the
M Mobility System is also provided on the
device.<
Before using the M Mobility System, note
the information on the sealant bottle.<
Pull the sticker for the speed limit off the sealant
bottle and affix it to the steering wheel.
Please observe the expiry date on the
sealant bottle.<

When reinstalling the cover, make sure
that its tabs are inserted into the corre-
sponding cut-outs in the cargo bay trim panel.

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 hose9 onto connection of sealant
bottle.
3.Unscrew and remove dust cap from valve of
defective wheel and screw filler hose2 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 hose9 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. Switch off
the device briefly to check the tire's cur-
rent inflation pressure.
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.<
