Driving comfortVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
Cruise control The concept
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
The vehicle stores and maintains the speed
specified using the controls on the steering
wheel.
Do not use cruise control
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident. ◀

▷The transmission position D is disengaged.▷DSC intervenes.
Maintaining, storing the current speedPress button 1 or button 3.
The current speed is maintained and stored. It
is displayed briefly in the tachometer.
On downhill gradients, it may prove impossible
to maintain the set speed if the engine braking
power is insufficient. On uphill gradients, it may
prove impossible to maintain the set speed if
the engine power output is insufficient.
Increasing speed
▷Press button 1 repeatedly until the desired
speed is reached.
Each time the button is pressed, the speed
increases by approx. 1 mph/1 km/h.▷Press and hold button 1 until the desired
speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. After the button is
released, the achieved speed is maintained
and stored.
Decreasing speed
Press button 3 repeatedly or hold it until the
desired speed is reached.
The functions are the same those when the
speed is increased, only that the speed is re‐
duced.
Resuming a speed stored beforehand Press button 4.
The last stored speed is resumed and main‐
tained.
The stored speed is cleared when the ignition is
switched off.
Display in the tachometer
The selected speed is displayed briefly.
If the display --- mph or --- km/h appears
briefly, conditions may not be adequate to op‐
erate the system.
For better control The indicator lamp lights up in the
speedometer. Cruise control is ready to
operate and can be activated.
Malfunction The warning lamp in the tachometer
lights up. A message appears on the
Control Display. The system is malfunc‐
tioning or has failed.
Park Distance Control
PDC
The concept
PDC provides support when parking in reverse.
Signal tones and a visual display indicate that
the vehicle is approaching an object behind it.
Measurements are made by four ultrasound
sensors in the bumpers.
The range of these sensors is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the two corner sensors at ap‐
prox. 24 in/60 cm.Seite 106ControlsDriving comfort106
Online Edition for Part no. 01 40 2 911 498 - VI/13
Page 107 of 288

▷By the rear middle sensors at approx.
5 ft/1.50 m.
Avoid driving quickly with PDC
PDC is a parking aid that can display ob‐
jects when the vehicle approaches them slowly,
as is the case during parking maneuvers. Avoid
driving toward an object quickly as the system
may then be too late in issuing a warning for
technical reasons. ◀
Automatic operation
The system is activated after approx. one sec‐ ond when reverse gear or selector lever posi‐
tion R is engaged while the engine is running or
the ignition is switched on. Await this short pe‐
riod before setting the vehicle into motion.
Signal tones
The closer the vehicle is to the object, the
shorter the intervals become. If the distance to
a detected object is less than approx.
12 in/30 cm, a continuous tone is sounded.
If the distance remains constant, for example
when driving parallel to a wall, the signal tone
is stopped after approx. 3 seconds.
PDC with visual warning
Displaying the approach to an object on the
Control Display. The contours of distant objects
are displayed on the Control Display before a
signal tone is output. The display is shown on
the Control Display as soon as reverse gear or
selector lever position R is engaged.
System limits Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone. ◀
Malfunction The warning lamp lights up. A message
appears on the Control Display. PDC is
malfunctioning or has failed. Have the
system checked.
To ensure full functionality of the sensors, keep
the sensors clean and free of ice. When using
high-pressure washers, do not spray the sen‐
sors for long periods and maintain a distance of
at least 12 in/30 cm.Seite 107Driving comfortControls107

Cooling functionThe passenger compartment can
only be cooled with the engine
running.
The cooling function cools and
dehumidifies the incoming air
before reheating it as required, according to
the temperature setting.
The cooling function helps to prevent conden‐
sation on the windows or to remove it quickly.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
To cool the air faster and more intensively
when external temperatures are high, switch
on the recirculated air mode.
Recirculated air mode If the air outside the car has an
unpleasant odor or contains pol‐
lutants, shut off the supply to the
interior of the car temporarily.
The system then recirculates the
air currently within the vehicle.
Should the windows fog up in the recirculated-
air mode, press the AUTO button or switch off
the recirculated-air mode and increase the air
volume if necessary. Make sure that air can
flow onto the windshield.
Recirculated air mode is automatically deacti‐
vated at low external temperatures.
Only use recirculated air mode for a lim‐
ited period
The recirculated air mode should not be used
continuously for lengthy periods; otherwise, the
quality of the air inside the car will gradually
deteriorate. ◀Temperature
