Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
Your service center will be glad to advise you.
Mobility System
The concept With the Mobility System, minor tire damagecan be sealed quickly 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.
Hints▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact the nearest service center if the
tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if needed.
Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Storage
The Mobility System is located under the
cargo floor panel.

7.With the ignition turned on or the engine
running, reel on the compressor.
Switch off the compressor after 10 mi‐
nutes
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
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 reel off the compressor 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 service center.
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 tire
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, reel
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 defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.

Snow chains
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.
Information about the approved snow chains
are available from the service center.
Use Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷245/50 R 18.▷245/45 R 19.
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing to the chain manufacturer's instructions.
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.
Maximum speed with snow chains Do not exceed a speed of 30 mph/50 km/hwhen using snow chains.
Snow chain detection
The concept When using snow chains, settings should bemade via the iDrive for the snow chains being
applied.
The snow chain detection system supports
you by automatically showing the detected
state on the Control Display.
When snow chains are in use, the rear axle
steering of the Integral Active Steering is deac‐
tivated automatically.
At speeds above the maximum permitted
speed with snow chains of 30 mph/50 km/h,
the rear axle steering is activated again auto‐
matically.
Activating the status1."Settings"2."Tire chains"3."Tire chains installed"
Automatic detection If functioning properly:
▷Snow chains are mounted. Settings are not
activated
.
After you drive a short distance, a Check
Control message is shown and the state is
activated automatically.
Confirm the automatic activation.
▷Snow chains are not mounted. Settings are
activated
.
At speeds above 30 mph/50 km/h, a Check
Control message is displayed. Deactivate
the status manually.
If not functioning properly:
▷Snow chains are mounted. Settings are not
activated
.
A Check Control message is not displayed.
The automatic detection system is mal‐
functioning. Activate the status manually.
Activating/deactivating rear axle
steering
If the status indicating that snow chains are in
use is activated, the rear axle steering is deac‐
tivated automatically.
At speeds above 30 mph/50 km/h, the rear axle
steering is activated again, even though snow
chains are in use.

Changing wheels
Hints
When using run-flat tires or sealants, a tire
does not need to be changed immediately in
the event of pressure loss due to a flat tire.
Which is why no spare tire is available.
The tools for changing wheels are available as
accessories from your service center.
Jacking points for the vehicle jack
The jacking points for the vehicle jack are lo‐
cated at the positions shown.
Vehicle battery Maintenance
The battery is maintenance-free.
The added amount of acid is sufficient for the
service life of the battery.

CareVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Car washes General information
Regularly remove foreign objects such as
leaves in the area below the windshield when
the hood is raised.
Wash your vehicle frequently, particularly in
winter. Intense soiling and road salt can dam‐
age the vehicle.
Hints Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
If the vehicle has a glass sunroof, ensure that a
distance of at least 31.5 inches/80 cm is main‐
tained. Holding them too close or using exces‐
sively high pressures or temperatures can
cause damage or preliminary damage that may
then lead to long-term damage.
Follow the user's manual for the high-pressure
washer.◀Cleaning sensors/camera lenses with
high-pressure washers
When using high-pressure washers, do not
spray the sensors and camera lenses on the
outside of the vehicle for long periods and
maintain a distance of at least 12 in/30 cm.◀
Automatic car washes
Hints Do not use high pressure washing sys‐
tems
With washing systems operating at high pres‐
sures and nozzle positions close to the win‐
dows, drops of water can penetrate.◀
Note the following:▷Give preference to cloth car washes or
those that use soft brushes in order to
avoid paint damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 79, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
of the alarm system. Follow the instruc‐
tions on avoiding an unintentional alarm,
refer to page 49.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.◀
