Mobility
System
Concept
With the Mobility System, minor tire damage can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the inside.
The compressor can be used to check the tire inflation pressure.
General
information
'yFollow the instructions on using the Mobij lity System found on the compressor and
sealant container.'yUse of the Mobility System may be ineffecj
tive if the tire puncture measures approx.
1/8 inches/4 mm or more.'yContact a dealerss service center or anj other qualified service center or repair
shop if the tire cannot be made drivable.'yIf possible, do not remove foreign bodies that have penetrated the tire.'yPull the speed limit sticker off the sealant
container and apply it to the steering
wheel.'yThe use of a sealant can damage the TPM wheel electronics. In this case, have theelectronics checked and replaced at the
next opportunity.
Storage
The Mobility System is located under thecargo floor panel.

5.Screw the connection hose onto the tirevalve of the nonworking wheel.6.With the compressor switched off, insert
the plug into a power socket inside the vej
hicle.7.With the ignition switched on or the engine running, switch on the compressor.
DANGER
If the exhaust pipe is blocked or ventilaj
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases conj tain pollutants which are colorless and odorj
less. In enclosed areas, exhaust gases can also
accumulate outside of the vehicle. There is
danger to life. Keep the exhaust pipe free and
ensure sufficient ventilation.'

If possible, do not drive at speeds less than12 mph/20 km/h.
Correcting

inflation
pressure1.Stop at a suitable location.2.Screw the connection hose onto the tire valve stem.3.Attach the connection hose directly to the
compressor.4.Insert the connector into the power socket
inside the vehicle.5.Correct the tire inflation pressure to
2.5 bar.'yIncrease pressure: with the ignition
switched on or the engine running,
switch on the compressor.'yTo reduce the pressure: press the butj ton on the compressor.
Continuing
the
trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Reinitialize the Tire Pressure Monitor.
Replace the nonworking tire and the sealant
container of the Mobility System promptly.
Snow

Fine-link
snow
chains
The manufacturer of your vehicle recommends use of fine-link snow chains. Certain types of
fine-link snow chains have been tested by the
manufacturer of the vehicle and recommended as road-safe and suitable.
Information regarding suitable snow chains is
available from a dealerss service center or anj other qualified service center or repair shop.
Use WARNING
With the mounting of snow chains on unj
suitable tires, the snow chains can come into

cidents or risk of property damage. Only mount
snow chains on tires that are designated by
their manufacturer as suitable for the use of
snow chains.'

cording to the snow chain manufacturer's inj
structions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result

in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control, if needed.
Maximum
speed

snow
chains
Do not exceed a speed of 30 mph/50 km/h when using snow chains.
Changing
wheels/tires General
information When using run-flat tires or tire sealants, a tire
does not always need to be changed immedij ately in the event of pressure loss due to a flattire.
If needed, the tools for changing wheels are available as accessories from a dealerss service
center or another qualified service center or rej pair shop.
Safety
information WARNING
The vehicle jack is provided by the vehij
cle manufacturer for changing wheels in the
event of a flat tire. The vehicle jack is not dej
signed for frequent use, for instance for changj
ing from summer to winter tires. Using the vej
hicle jack frequently may cause it to jam or
become damaged. There is a risk of injury and
risk of damage to property. Only use the vehij
cle jack to change an emergency wheel or a
spare tire in the event of a flat tire.'

Securing
the
vehicle
against
rolling
General
information
The vehicle manufacturer recommends to adj
ditionally secure the vehicle against rolling
away when changing a wheel.
On
a
level
surface
Place chocks or other suitable objects, for exjample a rock, in front of and behind the wheel
that is diagonally opposite to the wheel that you wish to change.
On
a
slight
downhill
gradient
If you need to change a wheel on a slight downhill grade, place chocks and other suitajble objects, for instance a rock, under the
wheels of both the front and rear axles against
the rolling direction.
Preparing
the
vehicle
'yChange the wheel as far away as possible
from passing traffic.'yPark the vehicle on solid, non-slip and level ground.'ySwitch on the hazard warning system.'ySet the parking brake.'yEngage a gear or selector lever position P.'yAs soon as permitted by the traffic flow,have all vehicle occupants get out of the
vehicle and ensure that they remain outj side the immediate area in a safe place,
such as behind a guardrail.'yDepending on the equipment version, get tools and the emergency wheel from the
vehicle.'yIf necessary, set up a warning triangle or
portable hazard warning lamp at an approj priate distance.'yDo not place wood blocks or similar itemsunder the vehicle jack; otherwise, it cannot
reach its carrying capacity because of the
restricted height.'ySecure the vehicle additionally against rollj
ing.'yLoosen the lug bolts a half turn.

area.
The nonworking wheel cannot be stored under the cargo floor panel because of its
size.3.Check tire inflation pressure at the next opj
portunity and correct as needed.4.Reinitialize the Flat Tire Monitor.
