Filling with sealant
Adhere strictly to the specified proce-
dure, otherwise sealant could escape
under high pressure. <
1. Shake the sealant cylinder.
2. Remove the connecting hose 9 fully from
the compressor housing and screw it onto
the sealant cylinder connection. Ensure that
there are no bends in the connecting hose.
3. Insert the sealant cylinder into the com-
pressor housing so that the cylinder is
upright.
4. Unscrew the dust cap from the valve of the
damaged wheel, and screw the filler hose
2
of the sealant cylinder onto the valve.
5. Make sure that the compressor is switched
off.
6. Insert the connector 3 into the socket inside
the vehicle, see page 92 .
7. With the engine running:
Switch on the compressor and let run for
approx. 3 to 8 minutes to fill the sealant and
achieve a tyre pressure of approx. 2.5 bar,
approx. 36.3 psi.
While you are filling the sealant, the
inflation pressure can briefly rise to
approx. 5 bar, approx. 72.5 psi. In this
phase, do not switch the compressor off.
<
Do not let the compressor run for
more than 10 minutes. Otherwise the
device will overheat and could be dam-
aged.
<
8. Switch off the compressor.
If a tyre pressure of 2 bar/29 psi is not achieved:
1. Unscrew and remove the filler hose 2 from
the wheel and drive forwards then reverse
for approx. 10 m, approx. 33 ft, each to allow
the sealant to be distributed in the tyre.
2. Pump up the tyre again with the compres-
sor.
If a tyre pressure of 2 bar/29 psi still can-
not be achieved, the tyre damage is too
severe. Consult the nearest BMW Service. <
Remove the connecting hose 9 and filler hose 2
from the connection to the sealant cylinder and
disconnect from the tyre valve.
To prevent soiling of the luggage area, wrap the
empty sealant cylinder. Stow away the Mobility
System again in the car.
Distributing the sealant
Immediately drive approx. 5 km or approx.
3 miles, so that the sealant is evenly distributed
inside the tyre.
Do not exceed a speed of 80 km/h or
50 mph. A minimum speed of 20 km/h or
12 mph should be observed where possible. <
Adjusting the tyre pressure
1. Stop in a suitable place after driving for
approx. 5 km, approx. 3 miles.
2. Screw the connecting hose 9 of the com-
pressor directly onto the tyre valve.
3. Insert the connector 3 into the socket inside
the vehicle.
4. Adjust the tyre pressure to 2.5 bar, approx.
36.3 psi. Additionally, with the engine run-
ning:
> To increase the tyre pressure: switch on
the compressor. Switch the compressor
off briefly to gauge the current tyre pres-
sure.
Do not allow the compressor to run
for longer than 10 minutes. Otherwise
the device will overheat and may be dam-
aged.
<
> To reduce the tyre pressure: press
deflating button
