Wheels and tires
Rotating wheels between axles
Changing run-flat tires
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Further infor‐
mation is available from a dealer’s service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure
and correct, if needed.
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 will be glad to answer
additional questions at any time.
Repairing a flat tire
Rotating the tires between the axes is not per‐
missible on vehicles with different tire sizes or
rim sizes on the front and rear axles.
Safety measures
▷
Park the vehicle as far away as possible
from passing traffic and on solid ground.
▷
▷
Switch on the hazard warning system.
Storage
Secure the vehicle against rolling away by
setting the parking brake.
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
▷
▷
Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.
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.
Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.
Run-flat tires
▷
If necessary, set up a warning triangle at an
appropriate distance.
Label
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.
RSC label on the tire sidewall.
The compressor can be used to check the tire
inflation pressure.
The wheels consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
General information
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 on using the Mobi‐
lity System found on the compressor and
sealant container.
Follow the instructions for continued driving
with a flat tire.

Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 inches/4 mm or more.
Compressor
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.

Filling the tire with sealant
1. Shake the sealant container.

3. Screw the connection hose onto the con‐
nector of the sealant container.
6. With the compressor switched off, insert
the plug into the power socket inside the
vehicle.
4. Insert the sealant container on the com‐
pressor housing in an upright position.
7. With the ignition turned on or the engine
running, switch on the compressor.
5. Screw the filling hose of the sealant con‐
tainer onto the tire valve of the nonworking
wheel.
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.◀
NOTE
The compressor can overheat during ex‐
tended operation. There is a risk of property
damage. 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.

Wheels and tires

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.
Correcting 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.
If a tire inflation pressure of 2 bar is not
reached:
3. Insert the connector into the power socket
inside the vehicle.
1. Switch off the compressor.
4. Correct the tire inflation pressure to
2.5 bar.
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.
▷
Increase pressure: with the ignition
turned on or the engine running, switch
on the compressor.
4. Inflate the tire again using the compressor.
▷
To reduce the pressure: press the but‐
ton on 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.
Continuing the trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Stowing the Mobility System
1. Unscrew the filling hose of the sealant con‐
tainer from the wheel.
Reinitialize the Flat Tire Monitor.
Reinitialize the Tire Pressure Monitor.
2. Unscrew the connection hose of the com‐
pressor from the sealant container.
Replace the nonworking tire and the sealant
container of the Mobility System as soon as
possible.
3. Connect the filling hose of the sealant con‐
tainer previously connected to the tire
valve with the available connector on the
sealant container.
Snow chains
This prevents leftover sealant from escap‐
ing from the container.
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.
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.
Information regarding suitable snow chains is
available from a dealer’s service center or an‐
other qualified service center or repair shop.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Use
WARNING
Do not exceed a speed of 50 mph/80 km/h.
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 risk of property damage. Only mount
If possible, do not drive at speeds less than
12 mph/20 km/h.
