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.Seite 202MobilityWheels and tires202

Approved wheels and tires
You should only use wheels and tires
that have been approved by the vehicle manu‐
facturer for your vehicle type; otherwise, e.g.,
despite having the same official size ratings,
variations can lead to chassis contact and with
it, the risk of severe accidents
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot guarantee the operating safety of the
vehicle.◀
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.
With proper use, these tires meet the highest
standards for safety and handling.
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 axlesDifferent 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.Seite 205Wheels and tiresMobility205
Online Edition for Part no. 01 40 2 956 336 - X/14
StorageStore 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
Use only in pairs on the rear wheels, equipped
with the tires of the following size:▷225/55 R 17.▷245/45 R 18.▷245/40 R 19.
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.
Snow chain detection
The concept When using snow chains, settings should bemade via the iDrive for the snow chains being
applied.
The snow chain detection system supports
you by automatically showing the detected
state on the Control Display.
When snow chains are in use, the rear axle
steering of the Integral Active Steering is deac‐
tivated automatically.
At speeds above the maximum permitted
speed with snow chains of 30 mph/50 km/h,
the rear axle steering is activated again auto‐
matically.

Changing wheels
Hints
When using run-flat tires or sealants, a tire
does not need to be changed immediately in
the event of pressure loss due to a flat tire.
Which is why no spare tire is available.
The tools for changing wheels are available as
accessories from your service center.

CareVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Car washes
General information
Regularly remove foreign objects such as
leaves in the area below the windshield when
the hood is raised.
Wash your vehicle frequently, particularly in
winter. Intense soiling and road salt can dam‐
age the vehicle.
Hints Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
Holding them too close or using excessively
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 of
time 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.◀
Note the following:▷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 75, to avoid unintentional wiper acti‐
vation.▷Do not treat the convertible top with wax.
Ensure that a cycle without wax or a spe‐
cial cycle for convertibles is available.▷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.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.◀
Before driving into a car wash In order to ensure that the vehicle can roll in a
car wash, take the following steps:
