Park Distance Control PDC
Principle PDC supports you with parking. Slowly ap‐
proaching an object in behind, or with front
PDC, in front of, your vehicle is signalled by
means of:
▷Acoustic signals.▷Visual display.
General
Ultrasonic sensors in each bumper measure
the distance.
The range is approximately 2 m, 6 ft depending on obstacle and environment.
An acoustic warning is only issued under the
following circumstances:
▷At the front sensors and at the two corner
sensors at the rear at approx. 60 cm, 24 in.▷At the central sensors at the rear at ap‐
prox. 1.5 m, 5 ft.▷If there is a collision risk.
Notes
WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing the traffic situation. Due to limits of the sys‐
tem, it cannot respond independently in a rea‐
sonable way in all traffic conditions. Danger of accidents. Adapt driving style to the driving
conditions. Observe the traffic situation and in‐
tervene actively if the situation warrants it.◀
WARNING
If the vehicle is travelling at high speed
when PDC is activated, there may be a delayed
warning because of physical conditions. Dan‐
ger of injury or damage to property. Avoid ap‐
proaching an object at speed. Avoid moving off at speed while PDC is not yet active.◀

Audible warning signals An intermittent sound indicates position of an
object as the vehicle approaches it. For in‐
stance, if an object is identified to the rear left of the vehicle, the warning signal sounds from
the rear left loudspeaker.
The shorter the distance to an object be‐
comes, the shorter the intervals become.
If the distance to a detected object is less than
approximately 25 cm, 10 in, a continuous tone
sounds.
With front PDC: if there are objects in front of
and behind the vehicle, an alternating continu‐
ous tone sounds.

ample a coat.▷With external disruption to the ultrasound,
for example by passing vehicles or loud
machines.▷If the sensors are dirty, iced-up, damaged
or incorrectly adjusted.▷In certain weather conditions, for example
high humidity, rain, snowfall, extreme heat
or strong wind.▷With trailer noses and tow hitches of other
vehicles.▷With thin or wedge-shaped objects.▷With moving objects.▷For higher, protruding objects, for example
projecting walls or loads.▷For objects with corners and sharp edges.▷For objects with fine surfaces or struc‐
tures, for example fences.▷For objects with porous surfaces.
Low objects already indicated, such as kerbs,
may enter the sensors' blind areas before or
after a continuous tone is given.
False alarms
Under the following conditions, PDC can issue
a warning although there is no obstacle in the
detection range:
▷In heavy rain.▷If the sensors are very dirty or covered with
ice.▷If the sensors are covered with snow.▷On rough road surfaces.▷On uneven ground, for example speed
bumps.▷In large, rectangular buildings with smooth
walls, for example underground car parks.▷In car washes.▷Due to dense exhaust gas.▷Due to other ultrasonic sources, for exam‐
ple sweeping machines, steam-jet cleaners
or neon lights.

Air conditioning functions in detailSwitching system on/off
Switching on
Press any key, except▷Heated rear window.▷Seat heating
Switching off
In the lowest setting, press the left of
the button.
Temperature Turn the wheel to select the de‐
sired temperature.
The automatic air conditioning sets this tem‐ perature as quickly as possible, using higher
cooling or heating power if necessary. The
temperature is then maintained.
Avoid switching between different temperature
settings in rapid succession. The automatic air
conditioning will not then have sufficient time
to establish the temperature selected.
Cooling function
The interior can only be cooled when the en‐
gine is running.
Press the button.
Air is cooled and dried, then reheated
to suit the temperature setting.
Depending on weather conditions, the wind‐
screen and side windows may mist over mo‐
mentarily when the engine is started.
The cooling function is switched on automati‐
cally in the AUTO program.
When using the automatic air conditioning,
condensation water, see page 165, develops
that exits underneath the vehicle.
Maximum cooling effect Press the button.
System is set to lowest temperature,
optimum air flow and recirculated-air mode.
The air flows from the outlets for the upper
body area. Therefore open the ventilation vents.
The function is available through an outside
temperature of approximately 0 ℃/32 ℉ and
with the engine running.
The air flow can be adapted when the program
is active.
AUTO program Press the button.
The air flow, air distribution and tem‐
perature are automatically regulated.
Depending on the selected temperature, inten‐
sity AUTO program and external influences,
the air is directed towards the windscreen, side
windows, upper body, and into the footwell.
The cooling function, see page 145, is
switched on automatically in the AUTO pro‐
gram.
A condensation sensor also controls the pro‐
gram so that condensation is avoided as much
as possible.

inside the vehicle is then recirculated.
Press button repeatedly to call up an
operating mode:▷LEDs off: ambient air is constantly entering
the car.▷Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
shuts it out automatically.▷Right-hand LED on, recirculated-air mode:
the ambient air supply is permanently shut
off.
The recirculated-air mode automatically
switches off at low outside temperatures after
a given time, to avoid condensation.
Continuous recirculated-air mode deteriorates
the air quality in the interior and condensation
on the windows increases.
If there is condensation on the window, switch
off recirculated-air mode and press the AUTO
button to use the condensation sensor. Ensure
that air can flow towards the windscreen.
Adjusting the air flow manually To be able to adjust the air flow manually, first
