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. <
