8.With the ignition switch ed on or the engine
running, switch on the compressor.
Let the compressor ru n for approx. 3 to
8 minutes to fill the ti re with sealant and
achieve a tire inflation pressure of approx.
36 PSI/250 kPa.
9. Switch off the compressor.
While the tire is being f illed with sealant, the dis-
played inflation pressu re may briefly reach
approx. 73 PSI/500 kPa. Do not switch off the
compressor in this phase.
Do not run the engine in enclosed areas;
otherwise, the inhalati on of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon
monoxide, an odorless and colorless, but highly
toxic gas. <
Do not let the compre ssor run for more
than 10 minutes, otherwise the device will
overheat and may be damaged. <
If an inflation pressure of 29 PSI/2 bar cannot be
reached:
1. Switch off the compressor.
2. Unscrew the filler hose from the tire valve.
3. Drive 33 ft/10 m forward and in reverse to
distribute the sealing compound in the tire.
4. Inflate the tire again with the compressor.
If an inflation pressure of 29 PSI/200 kPa
still cannot be reached, the tire is too heavily
damaged. Contact your BMW center.Stowing Mobility System
1. Unscrew the filler hose of the sealant bottle
from the tire valve.
2. Unscrew the connecting hose of the
compressor from the sealant bottle.
3. Connect the filler hose of the sealant bottle
to the unoccupied connection on the
sealant bottle.
This prevents the rest of the sealant from
escaping from the bottle.
4. Wrap the empty sealant bottle in suitable
material to avoid dirtying the cargo area.
5. Stow Mobility System back in the vehicle.
Distributing the sealant
Immediately drive approx. 3 miles/5 km to
evenly distribute the sealant in the tire.
Do not exceed a speed of 50 mph/
80 km/h. If possible, do not fall below a
speed of 12 mph/20 km/h. <
Correcting the tire inflation pressure
1.Stop at a suitable location.
2. Connect connecting hose of the compres-
sor directly to the tire valve.
3. Insert the plug into th e power socket in the
vehicle interior.
4. Adjust the tire inflation pressure to 36 PSI/
250 kPa. With the engine running:
>To increase the inflation pressure: With
the ignition switched on or the engine
running, switch on the compressor.
To check the inflatio n pressure, switch
off the compressor.
> To reduce the inflation pressure: Press
the discharge button on the compres-
sor.
If the inflation pressure is not maintained,
drive the vehicle a second time, refer to
Distributing the sealant. Then repeat steps 1
to 4.
