tires
Do not drive with a tire tread depth of less than
0.12 inches/3 mm.
There is an increased risk of hydroplaning if the tire tread depth is less than 0.12 injches/3 mm.
Winter
tires
Do not drive with a tire tread depth of less than
0.16 inches/4 mm.
Below a tread depth of 0.16 inches/4 mm, tires are less suitable for winter operation.

They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire
damage
General
information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Driving over rough or damaged road surfaces, as well as debris, curbs and other obstaclescan cause serious damage to wheels, tires andsuspension parts. This is more likely to occurwith low-profile tires, which provide less cushj
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle malj functions:'yUnusual vibrations while driving.'yUnusual handling such as a strong tenjdency to pull to the left or right.
Damage can, e.g., be caused by driving over
curbs, road damage, or similar things.
Safety
information WARNING
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.'

about the correct wheel/tire combination andwheel rim versions for the vehicle.
Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle rej
sponse, use only tires with a single tread conj figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
WARNING
Wheels and tires which are not suitable
for your vehicle can damage parts of the vehij cle, e.g., due to contact with the body due to
tolerances despite the same official size rating.
There is a risk of an accident. The manufacj
turer of your vehicle strongly suggests that you use wheels and tires that have been recomjmended by the vehicle manufacturer for your
vehicle type.'

shop. After rotating, check the tire pressureand correct, if needed.
Rotating the tires between the axes is not perj missible on vehicles with different tire sizes orrim sizes on the front and rear axles.
Storage
Store 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 presj 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-supj porting, to a limited degree, and possibly spej
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 dealerss service center will be glad to answeradditional questions at any time.

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.'yTurn the steering wheel until the frontwheels are in the straight-ahead position
and engage the steering wheel lock.'yHave all vehicle occupants get out of the vehicle 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 at an
appropriate distance.
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.Seite 204MobilityWheels

'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 at the next opportujnity and have them replaced, if needed.
Storage
The Mobility System is located under thecargo floor panel.

the plug into a power socket inside the vej
hicle.7.With the ignition turned 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 carbon monoxide, an odorless and colorjless but highly toxic gas. In enclosed areas, exj
haust gases can also accumulate outside of
the vehicle. There is danger to life. Keep the
exhaust pipe free and ensure sufficient ventilaj tion.'

If a tire inflation pressure of 2 bar cannot be
reached, contact your dealerss service cenj ter or another qualified service center orrepair shop.
Stowing
the
Mobility
System
1.Remove the connection hose of the sealj
ant container from the wheel.2.Remove the connection hose from the sealant container.3.Wrap the empty sealant container and conj
nection hose in suitable material to avoid dirtying the cargo area.4.Stow the Mobility System back in the vehijcle.
Distributing
the
sealant
Immediately drive approx. 5 miles/10 km to enjsure that the sealant is evenly distributed in thetire.
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.
Correcting
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 the power socket
inside the vehicle.5.Correct the tire inflation pressure to
2.5 bar.'yIncrease pressure: with the ignition
turned 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 as soon as
possible.
