Run-flat tiresLabel
RSC label on the tire sidewall.
The wheels are composed of tires that are self-
supporting to a limited degree.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the
event of a tire inflation pressure loss.
Continued driving with a damaged tire, refer to
page 101.
Continued driving with a damaged tire, refer to
page 98.
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.
Repairing a flat tire Safety measures in case of a breakdown
Park the vehicle as far away as possible
from passing traffic and on solid ground.
Switch on the hazard warning system.
Turn the steering wheel until the front wheels
are in the straight-ahead position and engage
the steering wheel lock.
Secure the vehicle against rolling away by set‐
ting the parking brake.
Have all vehicle occupants get out of the vehi‐
cle and ensure that they remain outside the im‐
mediate area in a safe place, such as behind a
guardrail.
If necessary, set up a warning triangle at an ap‐
propriate distance.
Comply with all safety guidelines and regula‐
tions. ◀
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.
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 opportunity
and have them replaced if needed.
Storage
The Mobility System is located under the cargo
floor panel.

4.Slide the sealant container upright into the
holder on the compressor housing, ensur‐
ing that it engages audibly.5.Screw the connection hose onto the tire
valve of the defective wheel.6.With the compressor switched off, insert
the plug into a power socket inside the ve‐
hicle.7.With the ignition turned on or the engine
running, reel on the compressor.
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.
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. ◀
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. ◀
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 forward and back to distribute 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.Seite 183Wheels and tiresMOBILITY183

Stowing the Mobility System1.Remove the connection hose of the sealant
container from the wheel.2.Remove the connection hose from the seal‐
ant container.3.Wrap the empty sealant container and con‐
nection hose in suitable material to avoid
dirtying the cargo area.4.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 mls/10 km/h to
ensure 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 in‐
side the vehicle.5.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, refer to
page 100.
Reinitialize the Tire Pressure Monitor, refer to
page 96.
Replace the defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.

Snow chainsFine-link snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehi‐
cle, 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 front wheels, equipped
with the tires of the following size:▷175/65 R 15.▷175/60 R 16.
Follow the chain manufacturer's instructions.
Make sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according
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/h
when using snow chains.

General information
The engine oil consumption is dependent on
the driving style and driving conditions.
The engine oil consumption can increase in
case of, for example:▷Sporty driving.▷Break-in the engine.▷Idling of the engine.▷Usage of non-approved engine oil grades.
Therefore, regularly check the engine oil level
after refueling.
The vehicle is equipped with electronic oil
measurement.
The electronic oil measurement has two meas‐
uring principles.
▷Status display▷Detailed measurementElectronic oil measure‐
ment
Status display
The concept
The engine oil level is monitored electronically
while driving and shown on the Control Display.
If the engine oil level reaches the minimum
level, a check control message is displayed.
RequirementsA current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip is
displayed.
With frequent short-distance trips, perform a
detailed measurement.

Engine oil level display messages Different messages appear on the display de‐
pending on the engine oil level. Pay attention
to these messages.
If the engine oil level is too low within the next
125 miles/200 km, add engine oil, refer to
page 189.
Engine oil level too low
Add engine oil immediately; otherwise,
an insufficient amount of engine oil could result
in engine damage. ◀
