Technology for driving comfort and
safety
Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. Equipment is also described
that is not available because of, for example,
selected options or coun try version. This also
applies to safety relate d functions and systems.
Park Distance Control
PDC
The concept
PDC assists you with parking in reverse. Acoustic
signals and a visual indi cator warn you of the
presence of an object behind the vehicle. To
measure the distance, there are four ultrasonic
sensors in either bumper.
These sensors have a range of approx.
6.5 ft/2 m. However, an acoustic warning
does not sound until an object is approx. 24 in/
60 cm from the rear corner sensors, or approx.
5 ft/1.50 m from the rear center sensors.PDC is a
parking aid that can indicate objects when they
are approached slowly, as is usually the case
when parking. Avoid appr oaching an object at
high speed; otherwise, physical circumstances
may lead to the system warning being issued
too late. <
Automatic mode
With the engine running or the ignition switched
on, the system is activated automatically after
approx. 1 second when you engage reverse
gear or move the automatic transmission selec-
tor lever to position R. Wait this short period
before driving.
Acoustic signals
As the distance between vehicle and object
decreases, the intervals between the tones
become shorter. If the distance to the nearest
object falls to below roughly 1 ft/30 cm, then a
continuous tone sounds.
If the distance remains co nstant, e.g. when driv-
ing parallel to a wall, the acoustic signal stops
after approx. 3 seconds.
Malfunction
Indicator lamp lights up. PDC has failed.
A message appears on the Control Dis-
play. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not direct the
jet toward the sensors for lengthy periods and
only spray from a distance of at least 4 in/10 cm.
PDC with visual warning
To have the system show distances to objects on
the Control Display. The contours of distant
objects are shown on the Control Display even
before the acoustic sign al sounds. The display
appears on the Control Display as soon as the
transmission is shifted into reverse or the selec-
tor lever is moved into the R position.
System limitations
Even with PDC, final responsibility for esti-
mating the distance between the vehicle
and any obstructions always remains with the
driver. Sensors, too, have blind spots in which
objects cannot be dete cted. Moreover, ultra-
sonic detection can reach its physical limits with
objects such as trailer tow bars and couplings,
thin and wedge-shaped objects, etc. Low
objects already indicated, such as curbs, may

ers or telephone antennas, if there is a pos-
sibility that they could be damaged.

Automatic transmission
Before driving into the car wash, make sure that
the vehicle can roll:
1.Place the remote control, even with Comfort
Access, in the ignition lock.
2. Move the selector lever to position N.
3. Release the parking brake.
4. Switch off the engine.
5. Insert the remote control in the ignition lock
so that the vehicle can roll.
Steam jets/high-pressure washers
When using steam jets or high-pressure
washers, make sure th at you maintain suf-
ficient distance from the vehicle and do not
exceed a maximum temperature of 140 7/
60 6 .
If the distance is too close, the pressure too high,
or the temperature too high, parts of the vehicle
can be damaged, or water can penetrate.
Observe the operating instructions for high-
pressure washers. <
Do not spray sensors such as Park Dis-
tance Control with high-pressure washers
for a long time or at a di stance of less than 1 ft/
30 cm. <
Manual washing
Use a great deal of water and, if necessary, car
shampoo when washing your car by hand. Clean
the vehicle with a sponge or a washing brush
applying a slight amount of pressure.
Before cleaning the windshield, deacti-
vate the rain sensor or turn off the ignition
to prevent unintentional wiping. <
Observe local regulations regarding wash-
ing vehicles by hand. <
Headlamps
Do not wipe dry and do not use abrasive or cor-
rosive cleaning agents. Remove dirt and con-
tamination, such as inse cts, by soaking with
shampoo and then washing with plenty of
water.
Do not remove accumulated ice and snow with
an ice scraper; use window deicers instead.
Windows
Clean the outside and inside of the windows and
mirrors with a window cleaner.
Do not clean the mirrors with cleaners
containing quartz. <
Wiper blades
Clean with soapy water and change regularly to
prevent the formation of streaks.
Wax, preservatives and dirt on the win-
dows cause streaks wh en the windshield
wipers are on, and can cause premature wear of
the wiper blades and interfere with the rain sen-
sor. <
Paintwork, care
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggressive substances.
Environmental influences in areas with
increased air pollution or natural contaminants,
such as tree sap or pollen, can affect the vehicle
paintwork. It is therefore important to adjust the
frequency and extent of vehicle care corre-
spondingly.
Immediately remove any pa rticularly aggressive
substances, such as fuel that has overflowed, oil,
grease, brake fluid, or bird droppings; otherwise,
paint damage can be caused.
Removing paintwork damage
Depending on the severity of the damage,
immediately repair stone damage or
scratches to prevent rusting. <
