PDC Park Distance Con‐
trol
The concept
PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is avail‐
able - then the object is reported through:
▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on obsta‐
cles and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given with the fol‐
lowing circumstances:
▷By the front middle sensors and the two
corner sensors at approx. 24 inches/60 cm.
▷By the rear middle sensors at approx.
5 ft/1.50 m.
▷When a collision is imminent
Information
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic and vehicle surroundings closely and ac‐
tively interfere in the respective situations.◀
WARNING
Due to high speeds when PDC is acti‐
vated, the warning can be delayed due to phys‐
ical circumstances. There is risk of injuries or
risk of property damage. Avoid approaching an
object too fast. Avoid driving off fast while PDC
is not yet active.◀

angle and are continuously adjusted to the
steering wheel movements.
Turning circle lines
Turning circle lines can be superimposed on the
image of the rearview camera.
Turning circle lines show the course of the

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 information
The 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, for example 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.
Pressure specifications
The tire inflation pressure table, refer to
page 183, 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:
▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to 100 mph/
160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 183, and adjust as necessary.

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 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 label 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. Further information is availa‐
ble from a dealer’s service center or another
qualified service center or repair shop.
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. Further infor‐
mation is available from a dealer’s service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure and
correct 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 109.
Continued driving with a damaged tire, refer to
page 106.
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 will be glad to answer
additional questions at any time.
Repairing a flat tire
Safety measures
▷Park the vehicle as far away as possible
from passing traffic and on solid ground.
▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.
▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.
Seite 188MOBILITYWheels and tires188
Online Edition for Part no. 01 40 2 964 571 - X/15
▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.
▷If necessary, set up a warning triangle at an
appropriate distance.
Mobility System
The 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.
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 inches/4 mm or more.
▷Contact a dealer’s service center or another
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 opportunity
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 ex‐
haust pipe free and ensure sufficient ventila‐
tion.◀
Storage
The Mobility System is in a bag in the front left
of the trunk.
