Divide the tire load by 1.1. It must be greater than one-half of the vehicless Gross Axle
Weight Rating m GAWR. Note, front vs. rear GAWR and tire loads, respectively.

WARNING
The temperature grade for this tire is esj
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinflaj tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.'

Safety
informationWARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle control. There is a risk of an accident. If tiredamage is suspected while driving, immedijately reduce speed and stop. Have wheels andtires checked. For this purpose, drive carefully
to the nearest dealerss service center or anj
other qualified service center or repair shop.
Have vehicle towed or transported as
needed.'

Retreaded
tires
The manufacturer of your vehicle does not recj
ommend the use of retreaded tires.
WARNING
Retreaded tires can have different tire
casing structures. With advanced age the servj
ice life can be limited. There is a risk of an accij
dent. The manufacturer of your vehicle does not recommend the use of retreaded tires.'

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 dealerss service center will be glad to answer additional questions at any time.

Safety
measures'yPark the vehicle as far away as possible
from passing traffic and on solid ground.'ySwitch on the hazard warning system.'ySecure the vehicle against rolling away by setting the parking brake.'yHave all vehicle occupants get out of thevehicle and ensure that they remain outjside the immediate area in a safe place,
such as behind a guardrail.'yIf necessary, set up a warning triangle or
portable hazard warning light at a sufficient
distance.'yChange wheels only on a flat, solid and slip-resistant surface. On soft or slippery
ground, for example snow, ice, tiles, etc.,
the vehicle or the vehicle jack may slip
away sideways.'yDo not place wood blocks or similar items under the vehicle jack; otherwise, it cannot
reach its carrying capacity because of the
restricted height.'yIf the vehicle is raised, do not lie under the vehicle and do not start the engine, or else
there is a danger to life.
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.
The compressor can be used to check the tire inflation pressure.
General
information'yFollow the instructions on using the Mobij lity System found on the compressor and
sealant container.'yUse of the Mobility System may be ineffecj
tive if the tire puncture measures approx.
1/8 inches/4 mm or more.'yContact a dealerss service center or anj other qualified service center or repair
shop if the tire cannot be made drivable.'yIf possible, do not remove foreign bodies that have penetrated the tire.'yPull the speed limit sticker off the sealant
container and apply it to the steering
wheel.'yThe use of a sealant can damage the TPM wheel electronics. In this case, have theelectronics checked and replaced at the
next opportunity.
Storage
The Mobility System is located under thecargo floor panel.

5.Screw the connection hose onto the tirevalve of the nonworking wheel.6.With the compressor switched off, insert
the plug into a power socket inside the vej
hicle.7.With the ignition switched on or the engine running, switch on the compressor.
DANGER
If the exhaust pipe is blocked or ventilaj
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases conj tain pollutants which are colorless and odorj
less. In enclosed areas, exhaust gases can also
accumulate outside of the vehicle. There is
danger to life. Keep the exhaust pipe free and
ensure sufficient ventilation.'

If possible, do not drive at speeds less than12 mph/20 km/h.
Correcting
the
tire
inflation
pressure1.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 the power socket
inside the vehicle.5.Correct the tire inflation pressure to
2.5 bar.'yIncrease pressure: with the ignition
switched on or the engine running,
switch on the compressor.'yTo reduce the pressure: press the butj 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 promptly.
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 dealerss service center or anj other qualified service center or repair shop.
Use WARNING
With the mounting of snow chains on unj
suitable tires, the snow chains can come into
contact with vehicle parts. There is a risk of acj
cidents or risk of property damage. Only mount
snow chains on tires that are designated by
their manufacturer as suitable for the use of
snow chains.'
