Recommendation
Regardless of wear and tear, replace tires at
least every 6 years.
Uniform Tire Quality Grading Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire
graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐Seite 199Wheels and tiresMobility199
Online Edition for Part no. 01 40 2 964 144 - VI/15

cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B, and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired by law.
WARNING
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.◀RSC – Run-flat tires
Run-flat tires, refer to page 202, 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 in/3 mm.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in/3 mm.
Winter tires Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/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 re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.

Tire damage
General information Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Information Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
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 mal‐
functions:▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. If tire dam‐
age is suspected while driving, immediately re‐
duce speed and stop. Have wheels and tires
checked. For this purpose, drive carefully to
the nearest dealer’s service center or another
qualified service center or repair shop. Have
vehicle towed or transported as needed.◀
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. Do not re‐
pair damaged tires, but have them replaced.◀
Changing wheels and tires
Mounting Have mounting and wheel balancing carried
out by a dealer’s service center or another
qualified service center or repair shop.
Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the right wheel/tire combination and
wheel 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 re‐
sponse, use only tires with a single tread con‐ 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 vehi‐
cle, e. g. due to contact with the body due to
tolerances despite the same official size rating.
There is risk of an accident.◀
Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.

Online Edition for Part no. 01 40 2 964 144 - VI/15

New tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
WARNING
Retreated tires can have different tire
casing structures. With advanced age the serv‐
ice life can be limited. There is risk of an acci‐
dent. Do not use retreated tires.◀
Winter tires
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
Maximum speed of winter tires If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then a respective symbol is displayed in your
field of vision. The plate is available from a
dealer’s service center or another qualified
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 the
case of a flat tire. A dealer’s service center or
another qualified service center or repair shop
will be glad to answer additional questions at
any time.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. A dealer’s
service center or another qualified service cen‐
ter or repair shop will be glad to answer addi‐
tional questions at any time. After rotating,
check the tire pressure and correct if needed.
Rotating the tires is not permissible on vehi‐
cles with different tire sizes or rim 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 pres‐
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-sup‐
porting, to a limited degree, and possibly spe‐
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.
Seite 202MobilityWheels and tires202
Online Edition for Part no. 01 40 2 964 144 - VI/15

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
dealer’s service center or another qualified
service center or repair shop will be glad to an‐
swer additional questions at any time.
Mobility System The conceptWith 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.
Information▷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 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.
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.◀
Storage
The Mobility System is located under the cargo floor panel.

Filling the tire with sealant1.Shake the sealant container.2.Pull the connection hose fully out of the
compressor housing. Do not kink the hose.3.Screw the connection hose onto the con‐
nector of the sealant container.4.Insert the sealant container on the com‐
pressor housing in an upright position.5.Screw the filling hose of the sealant con‐
tainer onto the tire valve of the nonworking
wheel.6.With the compressor switched off, insert
the plug into the power socket inside the
vehicle.Seite 204MobilityWheels and tires204
Online Edition for Part no. 01 40 2 964 144 - VI/15

7.With the ignition turned on or the engine
running, switch on the compressor.
CAUTION
The compressor can overheat during ex‐
tended operation. There is 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.
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.
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 33 ft/10 m forward and back to dis‐
tribute 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 dealer’s service cen‐
ter or another qualified service center or
repair shop.
Stowing the Mobility System
1.Unscrew the filling hose of the sealant con‐
tainer from the wheel.2.Unscrew the connection hose of the com‐
pressor from the sealant container.3.Connect the filling hose of the sealant con‐
tainer previously connected to the tirevalve with the available connector on the
sealant container.
This prevents leftover sealant from escap‐
ing from the container.4.Wrap the empty sealant container in suita‐
ble material to avoid dirtying the trunk.5.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure 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 of the com‐
pressor directly onto the tire valve stem.3.Insert the connector into the power socket
inside the vehicle.4.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with the ignition
turned on or the engine running, switch
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.
Reinitialize the Tire Pressure Monitor.
Replace the nonworking tire and the sealant
container of the Mobility System as soon as
possible.
