4. Make sure that the screw on the rear
of the pressure gauge 3 is tightened
down. Turn on the M Mobility sys-
tem, position 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 system 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 1/4 miles / 2 km, so that the liquid
sealant distributes 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.<
Inflating tire to correct pressure1. Take out the hose with the pressure
gauge and screw it onto the valve.
Take the plug out and plug it into the
cigarette lighter socket in the pas-
senger compartment
2. Reset the air pressure to
29 psi/200 kilopascal, and:
>Increase tire pressure: switch on
the M Mobility System, position I.
Switch off the unit briefly to check
the current tire pressure
>Decrease tire pressure: turn the
screw on the back of the manome-
ter, 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 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 88 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.
Battery
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
MaintenanceThe battery is completely maintenance-
free. That means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions.
Please consult your BMW center
whenever you have any questions
concerning the battery. when the engine is not running. Use the
connections provided in the engine
compartment. For information on the
connections, see Jump-starting,
page 147.Disposal

FusesYou will find the fuses and information
on their respective allocation in the
glove compartment behind a panel with
two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<

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. 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.<
The auxiliary jump-starting terminal
located in your BMW's engine compart-
ment acts as the positive battery termi-
nal. Refer to the engine compartment
overview on page 124. The cover of this
auxiliary terminal is marked with a +.
1. Open the cover of the BMW auxiliary
jump-starting terminal. Do so by pull-
ing the tab – see arrow 1
2. Connect one terminal clamp of the
plus/+ jumper cable to the positive
terminal of the battery or to an auxil-
iary jump-starting terminal of the
support vehicle
3. Connect the second terminal clamp
of the plus/+ jumper cable to the
positive terminal of the battery or to
an auxiliary jump-starting terminal of
the vehicle to be started
4. Your BMW is equipped with a special
nut – see arrow 2 – to serve as the
ground or negative terminal.
Attach a terminal clamp of the
minus/– jumper cable to the negative
terminal of the support vehicle's bat-
tery or to a suitable ground on its
engine or bodywork
5. Attach the second terminal clamp of
the minus/– jumper cable to the neg-
ative terminal of the battery or to a
suitable ground on the engine or
bodywork of the vehicle to be
started.Starting the engine1. Start the engine of the support vehi-
cle and let it run for several minutes
at a slightly elevated engine idle
speed
