M Mobility System
Repairing a flat tire
To repair a flat tire, an M Mobility System is pro-
vided in your BMW Z4 M Roadster/Z4 M Coupe.
Using this system you can apply a sealant to the
inside of the tire, seal off the damaged area,
restore the tire inflation pressure and then con-
tinue driving.
Safety measures in the event of a flat:
Park the vehicle as far as possible from
passing traffic and on solid ground. Switch on
the hazard warning flashers.
Lock the steering wheel so that the wheels are
facing straight ahead. Apply the parking brake
and engage first or reve rse gear. Have all vehi-
cle occupants get out of the vehicle and ensure
that they remain outside the immediate area in a
safe place, such as behind a guardrail.
If a warning triangle
* or portable hazard warning
lamp
* is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all national safety guidelines
and regulations. <
Preparation
If possible, do not remove foreign bodies which
have penetrated the tire.

Pull the sticker for the sp eed limit off the sealant
bottle and affix it to the steering wheel.
Please observe the expiry date on the
sealant bottle. <
Roadster
The M Mobility System is located on the right-
hand side of the cargo bay on the battery cover.
With the convertible top closed, fold the

remove the Mobility Set. <
To avoid any damage when opening the
convertible top, make sure that the con-
vertible top compartment panel in the cargo bay
has been folded down. <
Coupe: access to the Mobility Set
1.Turn the quick-release fastener counter-
clockwise.
2. Pull out the cover. When reinstalling the cover, make sure
that its tabs are inserted into the corre-
sponding cut-outs in the cargo bay trim panel. <
The M Mobility System is located on the right-
hand side of the cargo bay in a compartment on
top of the battery.

1 Sealant bottle and sticker with speed limit
2 Filler hose from sealant bottle to wheel
3 Cable and connector to cigarette lighter
socket

9Connecting hose for connecting compres-
sor and sealant bottle or compressor and

Connector, cable and connecting hose are
attached to the bottom of the compressor.
Using the M Mobility System
To repair a flat tire with the M Mobility System,
proceed as follows:
> Fill sealant into wheel
> Distribute sealant
> Restore tire inflation pressure
Filling sealant into wheel
Strictly adhere to the specified order, oth-
erwise highly pressurized sealant could
escape. <
1. Shake sealant bottle.
2. Screw hose 9 onto connection of sealant
bottle.
3. Unscrew and remove dust cap from valve of
defective wheel and screw filler hose 2 of
sealant bottle onto valve.
4. Insert sealant bottle on compressor hous-
ing so that the bottle is in an upright posi-
tion.
5. Make sure that the device is switched off,
position 0.
6. Insert connector 3 into cigarette lighter
socket inside the vehicle.
7. With the ignition switched on:
Switch on the device and allow it to run for
approx. 3 minutes to fill the wheel with seal-
ant. It is not important what inflation pres-
sure the tire has after this. 8.
Switch off device.
9. Remove connecting hoses from connection
of sealant bottle and tire valve.
Stow the M Mobility System in the vehicle
again.
Distributing sealant
Immediately drive approx. 2 miles/3 km so that
the sealant is evenly distributed in the tire.
Do not exceed a speed of 35 mph or
60 km/h. Do not drive slower than 12 mph
or 20 km/h if possible. <
Restoring tire inflation pressure
1.After approx. 2 miles/3 km, pull over at a
suitable location.
2. Screw compressor hose 9 directly onto tire
valve.
3. Insert connector 3 into cigarette lighter
socket inside the vehicle.
4. Correct tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on:
>To increase inflation pressure: switch on
the compressor, position I. To check the
current pressure setting, briefly switch
off the device.
Do not allow the compressor to run
for more than 10 minutes, otherwise
the device will overheat and may be dam-
aged. <
> To reduce inflation pressure: press but-
ton 8.
If the inflation pressure is not maintained,
drive the vehicle again, refer to Distribut-
ing sealant. Then repeat steps 1 to 4 once.
Using the M Mobility System can be ineffective
with tire punctures larger than approx. 1/6 in/
4 mm. Please contact the nearest BMW center
or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel if the tire cannot be made ready for
driving with the M Mobility System. <
The tire inflation pressure must be at least
29 psi/200 kPa. Otherwise do not con-
tinue driving. <

Continued driving
Do not exceed the permissible maximum
speed of 50 mph or 80 km/h, otherwise
accidents could result. <
Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*. For more

ual.
Have the defective tire and the sealant bottle of
the M Mobility System replaced as soon as
