Wheels and tiresVehicle features and op‐
tions
This 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 sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Tire inflation pressure Safety informationThe tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pressure,
and correct it as needed, e.g. twice a month
and before a long trip. ◀
Tires have a natural, consistent loss of tire infla‐ tion pressure.
Tires heat up while driving, and the tire inflation
pressure increases along with the tire's temper‐
ature. The tire inflation pressure specifications
relate to cold tires or tires with the ambient
temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 0.1 bar.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire Moni‐
tor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.
Checking the inflation pressure of the
emergency wheel
Located behind the bumper on the underside
of the vehicle is an opening for checking the
tire inflation pressure.
Pressure specifications
The tire inflation pressure table, refer to
page 179, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
To identify the correct tire inflation pressure,
please note the following:

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 provide
better winter traction than summer tires, they
do not provide the same level of performance
as winter tires.
Maximum speed of winter tiresIf 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 front
and 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 center or repair shop
will be glad to answer additional questions at
any time.
After rotating, check the tire pressure and cor‐
rect if needed.
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 are composed of tires that are self-
supporting to a limited degree.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the
event of a tire inflation pressure loss.
Continued driving with a damaged tire, refer to
page 89.

The concept
The engine oil level is monitored electronically
while driving and shown on the radio display.
If the engine oil level reaches the minimum
level, a check control message is displayed.
RequirementsA current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip is
displayed.
With frequent short-distance trips, perform a
detailed measurement.
