Precautions in case of a flat tire:
M Mobility System
Stop the vehicle as far as possible
from passing traffic. Switch on the
hazard warning flashers.
For repairing a flat tire, you will find an
M Mobility system in the BMW M5. With
the aid of this system, you can apply a
liquid sealant to the inside of the tire,
thereby sealing off the damaged area,
and then continue driving.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse and engage the parking
brake.
The M Mobility system makes the trans-
port of a spare wheel superfluous and
minimizes the curb weight.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
The M Mobility system is located in the
luggage compartment under the floor
mat;
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.<
1 Lift up the floormat and then raise the
front cover panel.
2 Loosen the M Mobility system from
its storage location.
Please note that the system's
sealant container must be re-
placed every three years by your BMW
center if the device is not used.<

Use the M Mobility System
If possible, leave the foreign
object in the tire.<
Do not exceed the maximum
speed limits described below,
otherwise it could lead to accidents.
Before you use the M Mobility System,
read the warnings and danger notices
on the device carefully.<
1 Remove the warning sticker 5 for
maximum speed that is located on
top of the device and affix it to the
steering wheel.

2 Take off the round cover and take out
hose 4. Unscrew the valve from the
defective wheel and screw the hose
to the valve.

2 Connection hose with pressure
gauge for connecting the compressor
with the sealant container or to con-
nect the compressor to the wheel
3 Pressure gauge for indicating the tire

7 Directly, afterward, drive at least
1.2 miles (2 km), so that the liquid
sealant distributes evenly throughout
the inside of the tire. If possible drive
at no less than 15 mph (20 km/h), but
not more than 40 mph (60 km/h).
Stop in a suitable spot.
3 Flip open the cover and pull out the
enclosed protective gloves. Take out
hose 2 with the pressure gauge and
screw it to the connection on the
sealant container, as shown in the
illustration.
5 Make sure that the screw on the rear
of the pressure gauge 3 is tightened
down. Turn on the M Mobility System
(position 1, refer to illustration) and
allow 3 minutes to elapse, to let the
sealant flow in. At this point, it is
insignificant what the tire pressure is.
6 Turn off the device.
4 Make sure that the system has been
switched off (Position 0). Take out
plug 6 and plug it into the cigarette
lighter socket in the passenger com-
partment (refer to page 110).
Disconnect the connector hose from
the sealant container and the tire
valve. Stow the M Mobility System in
the luggage compartment.

If the inflation pressure does not
hold, complete step 10 and then
repeat steps 7 through 10.
Replace the defective tire as soon as
possible and have the wheel and tire
balanced. Reactivate the tire pressure
warning system (RDW), refer to
The use of the M Mobility System may
be ineffective if the damaged area in
the tire is larger than approx.

nearest BMW center if the tire with the
M Mobility System cannot be made
roadworthy, or contact BMW Roadside
Assistance at 1-800-332-4269.<
10 Unscrew the hose from the valve
and stow the M Mobility System in
the luggage compartment.
8 Take out the hose with the pressure
gauge and screw it onto the valve.
Take out the plug and plug it into
the cigarette lighter socket in the
passenger compartment.
When you start driving again, do not
exceed the permissible maximum
speed of 50 mph (80 km/h).
9 Inflate the tire pressure:
> To increase the tire pressure: turn
on the M Mobility System (posi-
tion I). To check the new tire
pressure briefly turn off the
device.
You will find corresponding instructions
for using the M Mobility System on the
device.
To reduce the tire pressure: turn
the screw on the back of the
pressure gauge, this will open the
air release valve.
