container has to be changed every
3 years by your BMW center, if the unit
has not been used.<
This is part of the M Mobility
system1 On/Off switch
2 Connection hose with manometer for
connecting the compressor with the
sealant container or to connect the
compressor to the wheel
3 Manometer for indicating the tire
pressure
4 Connector hose from the sealant
container to the wheel
5 Sticker for maximum speed
6 Plug and cable for the cigarette
lighter socket
7 Protective gloves (not shown).
Filling with sealant1. Take the round cover off and hose 4

cap from the defective wheel and
screw the hose to the valve. Keep
the dust cap in a safe place.

Repairing a flat tire2. Flip open the cover and pull on the
enclosed protective gloves. Take out
hose 2 with the manometer and
screw it to the terminal for the
sealant container as shown in the
illustration
3. Make sure that the system has been
switched off (Position 0).
Take out plug 6 and insert it into the
cigarette lighter socket in the
passenger compartment (refer to
page 93)
4. Make sure that the screw on the rear
of manometer 3 is tightened down.
Turn on the M Mobility system (Posi-
tion I, refer to illustration) and allow
minutes to elapse, to let the sealant
flow in. It does not matter afterward,
what the tire's inflation pressure is
5. Turn the sealant off.
Disconnect the connector hose from
the sealant container and the wheel
valve. Stow the M Mobility system in
the luggage compartment
Distributing the sealantRight afterward, drive at least 1.2 miles
(2 km), so that the liquid sealant distrib-
utes evenly throughout the inside of the
tire.
Do not exceed a maximum speed
of 40 mph (60 km/h). If possible,
keep the vehicle speed above 10 mph
(20 km/h). Stop in a suitable spot.<

Repairing a flat tire Inflating tire to correct pressure1. Take the hose with the manometer
out and screw it onto the valve.
Take the plug out and plug it into the
cigarette lighter socket in the
passenger compartment
2. Reset the air pressure to 29 psi
(200 kilopascal), and:
>Increase tire pressure: turn on the
M Mobility system (Position I). Turn
the unit off while you check the
current setting for the tire pressure
>Decrease tire pressure: turn the
screw on the back of the mano-
meter, a valve located there will
open
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
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. 0.16 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,
otherwise it could lead to accidents.<
After the flat tire has been fixed and you
start driving again, do not exceed a
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
balanced. Reinitialize the Flat Tire
Monitor, and refer to page 78 for further
information. 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.

Towing the vehicleTow fittingThe tow fitting, which can be
unscrewed, is in the luggage compart-
ment under the floor panel and must
remain in the vehicle. This fitting
is designed for installation in the tow
sockets located at the front and rear of
the vehicle. It is intended for towing on
paved road surfaces only.
It should not be used to pull a vehicle
out of deep snow, mud, sand, etc.
Comply with all applicable towing laws
and regulations at all times.Access to tow socketsFront:
Press out the cover panel with a screw-
driver above on the recess.
Rear:
Press out the cover panel with a screw-
driver above on the recess.
Screw the tow fittings in until they
are tight. If you do not, the threads
could be damaged.
Do not tow the vehicle by any compo-
nents of the running gear, or lash them
down in any way. If you do, the compo-
nents could be damaged, leading to
possible accidents.<
Keep the vehicles in line and avoid
towing at an offset angle. Ensure
that the tow rope connecting the two
vehicles is tight, with no slack, before
starting off.<
Use only a nylon towing strap to tow
the vehicle, since the inherent resil-
ience of this material helps protect both
vehicles from sudden jerking move-
ments.
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it will not be
possible to control vehicle handling. to page 131.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
