Run-flat tires, refer to page 224, are labeled
with a circular symbol containing the letters RSC marked on the sidewall.
M+S Winter and all-season tires with better cold
weather performance than summer tires.
Tire
tread Summer
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.
Minimum
tread
depth
Wear indicators are distributed around the tire's circumference and have the legally rejquired minimum height of 0.063 inj
ches/1.6 mm.
The wear indicators are marked on the tire
sidewall with TWI, Tread Wear Indicator.
Tire
damage
General
information Inspect your tires regularly for damage, foreignobjects 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 occur
with 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.'

WARNING
Tires can become damaged by driving
over obstacles, e.g., curbs or road damage, at high speed. Larger wheels have a smaller tire
cross-section. The smaller the tire cross-secj
tion, the higher the risk of tire damage. There
is a danger of accidents and property damage. If possible, drive around obstacles, or drive
over them slowly and carefully.'

Maximum
speed
of
winter
tiresIf the maximum speed of the vehicle is higher
than the permissible speed for the winter tires, then attach a corresponding information label/
sticker in the field of view. The label is available from a dealerss service center or another qualij
fied service center or repair shop.
With mounted winter tires, observe and adhere
to the permissible maximum speed.
Run-flat
tires If you are already using run-flat tires, for your
own safety you should replace them only with the same kind. No spare tire is available in thecase of a flat tire. Further information is availaj
ble from a dealerss service center or another qualified service center or repair shop.
Rotating
wheels
between
axles Different wear patterns can occur on the frontand rear axles depending on individual driving
conditions. The tires can be rotated between the axles to achieve even wear. Further inforjmation is available from a dealerss service cenjter or another qualified service center or repair
shop. After rotating, check the tire pressure and 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 and dark
place.
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
Concept
Run-flat tires permit continued driving under
restricted conditions even in the event of a complete loss of tire inflation pressure.
General
information
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.
Label
RSC label on the tire sidewall.
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.

'ySecure the vehicle against rolling away bysetting 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.
