4. Screw dust cap off valve of defective wheel
and screw filling hose
2 of sealant bottle
onto valve.
5. Insert sealant bottle on compressor hous-
ing so that it is positioned upright.
6. Make sure that the device is switched off,
position 0.
7. Insert connector 3 into lighter socket in
vehicle interior, refer to page 108 .
8. With the ignition switched on:
Switch on the device and allow to run for
approx. 3 minutes to fill wheel with sealant.
It is not important what inflation pressure
the tire has after filling.
9. Switch off device.
10. Remove connecting hose 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
sealant is evenly distributed in tire.
Do not exceed a maximum speed of
35 mph/60 km/h. Do not drop below
12 mph/20 km/h if possible. <
Producing tire inflation pressure
1. After approx. 2 miles/3 km, stop at suitable
location.
2. Screw compressor hose 9 directly onto tire
valve.
3. Insert connector 3 in lighter socket in vehi-
cle interior.
4. Correct tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on:
> Increase inflation pressure: switch on
compressor, position I. To check cur-
rently set inflation pressure, briefly
switch off device.
Do not allow compressor to run
longer than 10 minutes, otherwise
the device will overheat and may be dam-
aged.
<
> Reduce inflation pressure: press
button
8 or turn screw 8 on pressure
gauge.
If the inflation pressure is not held, drive
the vehicle again, refer to Distributing
sealant. Then repeat steps 1 to 4 once.
Using the M Mobility System can be ineffective
with tire damage from a size of approx. 0.16 in/
4 mm. Please contact the nearest BMW center,
refer to page
224 , or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel if the tire can-
not 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. <
Continue driving
Do not exceed the permissible maximum
speed of 50 mph/80 km/h, otherwise
accidents can occur. <
Reinitialize the Flat Tire Monitor.
For details, refer to page
83 .
Have the defective tire and the sealant bottle of
the M Mobility System replaced as soon as
possible.
