StorageStore wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires Label
RSC label on the tire sidewall.
The wheels consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a tire inflation pressure loss.
Follow the instructions for continued driving
with a flat tire.
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. A
dealer’s service center or another qualified
service center or repair shop will be glad to an‐
swer additional questions at any time.
Mobility System
The concept
With the Mobility System, minor tire damage
can 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.
Information▷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 a dealer’s service center or an‐
other qualified service center or repair
shop 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.
DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of
the vehicle. There is danger to life. Keep the
exhaust pipe free and ensure sufficient ventila‐
tion.◀

3.Wrap the empty sealant container and con‐
nection hose in suitable material to avoid
dirtying the trunk.4.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 onto the tire
valve stem.3.Attach the connection hose directly to the
compressor.4.Insert the connector into a power socket
inside the vehicle.5.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.

A spare lamp box is available from a dealer’s
service center or another qualified service cen‐
ter or repair shop.
WARNING
Bulbs can get hot during operation. Con‐
tact with the bulbs can cause burns. There is
risk of injuries. Only change bulbs after they
have cooled off.◀
WARNING
Work on switched-on lighting systems
can cause short circuits. There is risk of inju‐
ries or risk of property damage. When working
on the lighting system, switch off the lamps in
question. If necessary, heed the bulb manufac‐
turer's instructions.◀
CAUTION
Contaminated bulbs reduce their service
life. There is risk of property damage. Do not
hold new bulbs with your bare hands. Use a
clean cloth or something similar, or hold the
bulb by its base.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
WARNING
Too intensive brightness can irritate or
damage the retina of the eye. There is risk of
injuries. Do not look directly into the headlights
or other light sources for an extended period of
time. Do not remove the LED covers.◀
Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐
densation evaporates after a short time. The
headlight glass does not need to be changed.If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Headlight setting
The headlight adjustments can be affected by
changing lights and bulbs. After the headlight
adjustment was changed, have it checked and,
if necessary, corrected by a dealer’s service
center or another qualified service center or re‐
pair shop.

Driving with emergency wheel
WARNING
The emergency wheel has particular di‐
mensions. When driving with an emergency
wheel, changed driving properties may occur
at higher speeds, e.g. reduced lane stability
when braking, longer braking distance and
changed self-steering properties in the limit
area. There is risk of an accident. Drive moder‐
ately and do not exceed a speed of
50 mph/80 km/h.◀
