Even if the tire fails to hold the
pressure, you should still carry out
Step 3 before proceeding to drive the
vehicle again, refer to Distributing the
sealant for more information. Then
repeat Steps 1 through 3.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 1/8 in /
4 mm. Please consult the nearest BMW
center if the tire cannot be temporarily
repaired with the M Mobility system.<
3. Unscrew the hose from the valve and
stow the M Mobility system in the
luggage compartment. Screw the
dust cap onto the valve again.
Do not exceed the maximum
speed limit described below, oth-
erwise it could lead to accidents.<
When you start driving again, do not
exceed the permissible maximum
speed of 45 mph / 80 km/h.
You will find corresponding
instructions for using the
M Mobility system on the device.
Replace the defective tire as soon as
possible and have the new wheel bal-
anced. Reinitialize the Flat Tire Monitor,
and refer to page 85 for further informa-
tion. Have the M Mobility system
refilled. Contact your BMW center for
this.<
Protect valve stems against dirt using
screw-on dust caps. Dirty valve stems
frequently lead to slow pressure loss.

Jump-startingWhen your battery is discharged, you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Use only jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal.
Carefully observe the following instruc-
tions to avoid personal injury and/or
damage to one or both vehicles.<Preparations1. Check whether the battery of the
support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery
2. Stop the engine of the support vehi-
cle
3. Switch off all electrical components
in both vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles, otherwise
there is a short circuit hazard.<
Connecting the jumper cables
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
