4.Insert the sealant container on the com‐
pressor housing in an upright position.5.Screw the filling hose of the sealant con‐
tainer onto the tire valve of the nonworking
wheel.6.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.7.With the ignition turned on or the engine
running, switch on the compressor.
ATTENTION
The compressor can overheat during ex‐
tended operation. There is a risk of damage to
property. Do not run the compressor for more
than 10 min.◀
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the
tire inflation pressure may sporadically reach
approx. 5 bar. Do not switch off the compres‐
sor at this point.
If a tire inflation pressure of 2 bar is not
reached:
1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive 33 ft/10 m forward and back to dis‐
tribute the sealant in the tire.4.Inflate the tire again using the compressor.
If a tire inflation pressure of 2 bar cannot be
reached, contact your dealer’s service cen‐
ter or another qualified service center or
repair shop.
Stowing the Mobility System
1.Unscrew the filling hose of the sealant con‐
tainer from the wheel.2.Unscrew the connection hose of the com‐
pressor from the sealant container.3.Connect the filling hose of the sealant con‐
tainer previously connected to the tireSeite 214MobilityWheels and tires214

valve with the available connector on the
sealant container.
This prevents leftover sealant from escap‐
ing from the container.4.Wrap the empty sealant container in suita‐
ble material to avoid dirtying the cargo
area.5.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
To correct the tire inflation pressure
1.Stop at a suitable location.2.Screw the connection hose of the com‐
pressor directly onto the tire valve stem.3.Insert the connector into the power socket
inside the vehicle.4.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with the ignition
turned on or the engine running, switch
on the compressor.▷To reduce the pressure: press the but‐
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 as soon as
possible.
Snow chains
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 dealer’s service center or an‐
other qualified service center or repair shop.
Use WARNING
With the mounting of snow chains on un‐
suitable tires, the snow chains can come into
contact with vehicle parts. There is a risk of ac‐
cidents or a risk of property damage. Only
mount snow chains on tires that are desig‐
nated by their manufacturer as suitable for the
use of snow chains.◀
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷225/55 R 17.▷245/45 R 18.
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Re-tighten as needed ac‐
cording to the snow chain manufacturer's in‐
structions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure 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.
