Tire age
DOT … 4314: the tire was manufactured in the
43th week of 2014.
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.
Treadwear
The 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‐
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.

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.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
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. You can obtain this sign from the
tire specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the respective winter tires; otherwise, tire dam‐
age and accidents can occur.◀
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. Your service center will be
glad to advise you.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. Your service
center will be glad to advise you. After rotating,
check the tire pressure and correct if needed.
Rotating the tires is not permissible on vehi‐
cles with different tire sizes on the front and
rear axles, i.e. when using different types of
tires.
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.

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.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
Information about the approved snow chains
are available from the service center.
Use

with the tires of the following size:▷225/50 R 17.▷225/45 R 18.
Follow the snow chain manufacturer's instruc‐
tions.
Make sure that the snow chains are always
sufficiently tight. Retighten as needed accord‐
ing 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/hwhen using snow chains.

washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
If the vehicle has a glass sunroof, ensure that a
distance of at least 31.5 inches/80 cm is main‐
tained. Holding them too close or using exces‐
sively high pressures or temperatures can
cause damage or preliminary damage that may
then lead to long-term damage.
Follow the user's manual for the high-pressure
washer.◀
Cleaning sensors/cameras with high-
pressure washers
When using high-pressure washers, do not
spray the exterior sensors and cameras, e.g.,
Park Distance Control, for extended periods oftime and only from a distance of at least
12 in/30 cm.◀
Automatic car washes
Hints Do not use high pressure washing sys‐
tems
With washing systems operating at high pres‐
sures and nozzle positions close to the win‐
dows, drops of water can penetrate.◀▷Give preference to cloth car washes or
those that use soft brushes in order to
avoid paint damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 69, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
of the alarm system. Follow the instruc‐
tions on avoiding an unintentional alarm,
refer to page 45.
