Wheels and tires
Mobility
This prevents leftover sealant from escap‐
ing from the container.
Snow chains
4. Wrap the empty sealant container in suita‐
ble material to avoid dirtying the cargo
area.
Fine-link snow chains
Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
5. Stow the Mobility System back in the vehi‐
cle.
Information about the approved snow chains
are available from the service center.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
Do not exceed a speed of 50 mph/80 km/h.
▷
▷
▷
225/55 R 17.
245/45 R 18.
245/40 R 19.
If possible, do not drive at speeds less than
12 mph/20 km/h.
Follow the snow chain manufacturer's instruc‐
tions.
To correct the tire inflation pressure
1. Stop at a suitable location.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
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.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
4. Correct the tire inflation pressure to
2.5 bar.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
▷
Increase pressure: with the ignition
turned on or the engine running, reel
on the compressor.
When driving with snow chains, briefly activate
Dynamic Traction Control if needed.
▷
To reduce the pressure: press the but‐
ton on the compressor.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h
when using snow chains.
Continuing the trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Snow chain detection
The concept
When using snow chains, settings should be
made via the iDrive for the snow chains being
applied.
Reinitialize the Tire Pressure Monitor.
Replace the defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.
The snow chain detection system supports
you by automatically showing the detected
state on the Control Display.
