Replacement of wheels and
tyres
Fitting Have fitting and balancing performed by a
Service Partner or a qualified specialist work‐
shop.
Wheel and tyre combination The correct wheel and tyre combination and
rim designs for the vehicle can be consulted at
a Service Partner or a qualified specialist work‐
shop.
Incorrect wheel and tyre combinations will in‐
terfere with the proper functioning of various
systems, such as ABS and DSC.
To maintain good vehicle handling, always fit
tyres of the same make and tread pattern to all
wheels.
After a tyre has been damaged, fit the original
wheel and tyre combination again.
WARNING
Wheels and tyres that are categorised as
unsuitable by the vehicle manufacturer can
damage parts of the vehicle, for example by
touching the bodywork as a result of toleran‐
ces, in spite of having the same nominal size.
Danger of accidents. Use wheels and tyres that
have been categorised as suitable for the re‐
spective vehicle type by the vehicle manufac‐
turer.◀Recommended makes of tyre
Certain makes of tyre are recommended by the
manufacturer of your vehicle depending on
tyre size. These can be seen by the asterisk on
the side wall of the tyre.
New tyres New tyres do not achieve their full road
grip immediately, for production reasons.
During the first 300 km, 200 miles, drive mod‐
erately.
Retreaded tyres The manufacturer of your vehicle advises
against the use of retreaded tyres.
WARNING
Retreaded tyres can have various tyre
carcasses. Their durability may be reduced
with increasing age. Danger of accidents. Do
not use retreaded tyres.◀
Winter tyres For operation on wintry carriageways, winter
tyres are recommended.
Although so-called all-season tyres with an M
+S label have better winter characteristics than
summer tyres, they do not normally match the
performance of winter tyres.
Maximum speed of winter tyres
If the vehicle is capable of speeds higher than
the speed permitted for the winter tyres, an in‐
formation sticker stating the maximum permit‐

ted speed for the tyres fitted must be dis‐
played in the driver's field of view. The sticker
is available from a Service Partner or a qualified
specialist workshop.
If winter tyres are fitted, observe and comply
with the respectively permitted maximum
speed.
Interchanging front and rear wheels
The manufacturer of your vehicle advises
against interchanging the front and rear
wheels. This could impair vehicle handling
Such a change is not permitted in vehicles with
different tyre or rim dimensions on the front
and rear axles.
Tyre storage
Store wheels and tyres in a cool, dry and pref‐
erably dark place when not in use.
Protect tyres against contamination from oil,
grease and fuel.
Do not exceed the maximum tyre pressure in‐
dicated on the tyre's side wall.
Remedying flat tyres Safety measures▷Park the vehicle on a solid surface and as
far away from moving traffic as possible.▷Switch on hazard warning lights.▷Protect the vehicle against rolling, by ap‐
plying the parking brake.▷Engage the steering wheel lock in the
straight ahead position of the wheels.▷Allow all vehicle occupants get out of the
vehicle and guide them out of the danger
area, for example behind the crash barrier.▷Set up warning triangle an appropriate dis‐
tance away.Mobility system
Principle With the mobility system, minor tyre damage
can be quickly sealed, to allow you to drive on.
To do that, liquid sealant is pumped into the
tyres which encloses the damage from the in‐ side when it hardens.
The compressor can be used to check the tyre
inflation pressure.
Notes▷Please observe the notes on the applica‐
tion of the Mobility system which are on
the compressor and the sealant container.▷Applying the Mobility system can be inef‐
fective for tyre damage as from a size of
approximately 4 mm.▷Contact a Service Partner or a qualified
specialist workshop if you are unable to put
the tyre back in operation.▷If possible, foreign matter that has penetra‐
ted the tyre should remain inside the tyre.▷Remove the speed limit sticker from the
sealant container and attach to the steer‐
ing wheel.▷Using sealants can damage the TPM wheel
electronics. If sealant is used, check the
electronics as soon as you get an opportu‐
nity and have them replaced if necessary.
DANGER
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust fumes to
penetrate the vehicle. The exhaust gas con‐
tains carbon monoxide, which is colourless and
odourless, but highly toxic. In enclosed spaces,
the exhaust fumes can also build up outside
the vehicle. Danger of fatal injury. Keep the ex‐
haust pipe clear and ensure sufficient ventila‐
tion.◀
Storage
Mobility system is located under boot floor.

4.Insert the upright sealant container into the
compressor housing.5.Screw the filler hose of the sealant con‐
tainer onto the tyre valve of the faulty
wheel.6.Insert the plug into the socket on the inside
of the vehicle while the compressor is
switched off.7.Switch on the compressor with the ignition
switched on or the engine running.
ATTENTION
The compressor can overheat if operated
for too long. Danger of damage to property. Do
not let the compressor run for longer than 10
minutes.◀
Let the compressor run for approximately
three to 8 minutes to fill the sealing compound
and achieve a tyre inflation pressure of approx‐
imately 2.5 bar.
The tyre inflation pressure may rise to approxi‐
mately 5 bar during the filling process of the
sealing compound. Do not switch off the com‐
pressor during this step.
If it does not reach a tyre inflation pressure of
2 bar:
1.Switch off compressor.2.Remove the filler hose from the wheel.3.Drive forwards and backwards by 10 m, ap‐
proximately 400 inches to distribute the
sealant in the tyre.4.Re-inflate the tyre with the compressor.
Contact a Service Partner or a qualified
specialist workshop if the device does not
reach a tyre inflation pressure of 2 bar.
Storing Mobility system
1.Remove the filler hose of the sealant con‐
tainer from the wheel.2.Remove the connecting hose of the com‐
pressor from the sealant container.Seite 180MobilityWheels and tyres180

3.Take the filler hose of the sealant container
that was previously connected to the tyre
valve and connect it to the free connection
on the sealant container.
This can prevent sealant residues from es‐
caping from the container.4.Pack empty sealant container to avoid soil‐
ing in the boot.5.Store Mobility system in the vehicle again.
Spreading sealant compound
Immediately drive for approximately
10 km/5 mi to evenly distribute the sealing
compound in the tyre.
Do not exceed a speed of 80 km/h/50 mph.
If possible, do not drive slower than
20 km/h/12 mph.
Correcting the tyre inflation pressure
1.Stop in a suitable area.2.Bolt the connecting hose of the compres‐
sor directly onto the tyre valve.3.Insert the plug into the socket on the inside
of the vehicle.4.Correct tyre inflation pressure to 2.5 bar.▷Increase pressure: switch on the com‐
pressor with the engine running or the
ignition switched on.▷Reduce pressure: press the button on
the compressor.
Continuing with journey
Do not exceed maximum permitted speed of
80 km/h, approximately 50 mph.
Reinitialise runflat indicator.
Reinitialise Tyre Pressure Monitor.
Have the punctured tyre and the sealant con‐
tainer of the Mobility system replaced as soon
as possible.
Snow chains
Fine-link snow chains Only certain fine-link snow chains have been
tested, found safe for use in traffic, and cate‐
gorised as suitable by the manufacturer of your
vehicle.
Information regarding suitable snow chains is
available from a Service Partner or a qualified
specialist workshop.
Using Snow chains may only be used in pairs on the
rear wheels with tyres of the following sizes:▷255/40 R 18.▷255/35 R 19.
Observe the snow chain manufacturer's notes.
Ensure that the snow chains are always ade‐
quately taut. Re-tighten them if necessary in
accordance with the chain manufacturer's in‐
structions.
Do not initialise the runflat indicator with snow
chains fitted, as the instrument might other‐
wise issue an incorrect reading.
Do not initialise the Tyre Pressure Monitor with
snow chains fitted, as the instrument might
otherwise issue an incorrect reading.
When driving with snow chains, activate M Dy‐
namic Mode briefly if necessary.
Maximum speed with snow chains
When snow chains are fitted, do not exceed
50 km/h, 30 mph.
