Mobility
SystemPrinciple
With the Mobility System, minor tyre damage can be quickly sealed, to allow you to drive on.
For this purpose, liquid sealant is pumped into the tyres which encloses the damage from the
inside when it hardens.
General'yPlease observe the notes on the applicaj tion of the Mobility System which are on
the compressor and the sealant container.'yApplying the Mobility System can be inefj
fective for tyre damage larger than approxij
mately 4 mm.'yContact a Service Partner of the manufacj turer or another qualified Service Partner or
a specialist workshop if you are unable to
put the tyre back in operation.'yIf possible, foreign matter that has penetraj ted the tyre should remain inside the tyre.
Only remove foreign objects if they are
visibly protruding from the tyre.'yRemove the speed limit sticker from the sealant container and attach to the steerj
ing wheel.'yUsing sealants can damage the TPM wheel
electronics. In this case, have the TPM wheel electronics replaced at the next opj
portunity.'yThe compressor can be used to check the
tyre inflation pressure.
Storage
The Mobility System is located under the boot
floor.

container onto the tyre valve of the faulty
wheel.6.Insert the plug into the socket in the vehij
cle interior while the compressor is switched off.7.Switch on the compressor with the ignition
switched on or the engine running.
Let the compressor run for approximately 10 minutes to fill the sealing compound andachieve a tyre inflation pressure of approxij
mately 2.5 bar.
The tyre inflation pressure may rise to approxij
mately 5 bar during the filling process of the
sealing compound. Do not switch off the comj pressor during this step.
If it does not reach a tyre inflation pressure of
2 bar:1.Switch off compressor.2.Unplug the connector from the socket in the vehicle interior.3.Unscrew the filler hose from the tyre valve.4.Drive forwards and backwards by 10 m, apj
proximately 400 inches, to distribute the sealant in the tyre.5.Re-inflate the tyre with the compressor.
Contact a Service Partner of the manufacjturer or another qualified Service Partner or
a specialist workshop if the device does not reach a tyre inflation pressure of 2 bar.
Storing
Mobility
system
1.Unscrew the filler hose of the sealant conjtainer from the tyre valve.2.Unplug the compressor connector from
the socket in the vehicle interior.3.Remove the connecting hose of the comj pressor from the sealant container.4.Take the filler hose of the sealant containerthat was previously connected to the tyre
valve and connect it to the free connection on the sealant container.
This can prevent sealant residues escapj ing from the sealant container.5.Pack and store the sealant container to
avoid soiling the boot.6.Stow the Mobility System in the boot
again.
Spreading
sealant
compound
Immediately drive for approximately 10 km/5 miles to evenly distribute the sealing
compound in the tyre.
Do not exceed the permissible maximum speed of 80 km/h/50 mph.
If possible, do not drive slower than
20 km/h/12 mph.

pressure1.Stop in a suitable area.2.Screw the connecting hose of the comjpressor directly onto the tyre valve.3.Insert the plug into the socket in the vehij
cle interior.4.Correct tyre inflation pressure to 2.5 bar.'yTo increase the tyre inflation pressure:
switch on the compressor with the enj gine running or the ignition switched
on.'yTo reduce tyre inflation pressure: press the button on the compressor.
Resuming
with
journey
Do not exceed maximum permitted speed of 80 km/h, approximately 50 mph.
Reinitialise the runflat indicator RPA.

of the Mobility System replaced at the next opj
portunity.
Snow
chains
Fine-link
snow
chains
The manufacturer of your vehicle recommends
using fine-link snow chains. Certain fine-link
snow chains have been tested, found safe for
use in traffic, and categorised as suitable by
the manufacturer of the vehicle.
Information regarding suitable snow chains is available from a Service Partner of the manuj
facturer or another qualified Service Partner or
a specialist workshop.
