LampsVehicle equipmentThis 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.

General information
When the driver's door is opened with the igni‐
tion switched off, the exterior lighting is auto‐
matically switched off when the light switch is
in position 0, 2, or 3.
Switch on the parking lamps if necessary,
switch position 1.
Parking lamps Switch position 1: the vehicle lamps light up on
all sides.
Do not use the parking lamps for extended pe‐
riods; otherwise, the battery may become dis‐
charged and it would then be impossible to
start the engine.
When parking, it is preferable to switch on the
one-sided roadside parking lamps, refer to
page 86.
Low beams Switch position 2: the low beams are lit when
the ignition is switched on.
Automatic headlamp control Switch position 3: the low beams are switched
on and off automatically depending on the am‐
bient light, e.g., in tunnels, in twilight, or if
there is precipitation. Adaptive Light Control is
active.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain switched on independ‐
ent of the ambient lighting conditions when
you switch on the front fog lamps.
Personal responsibility
The automatic headlamp control cannot
serve as a substitute for your personal judg‐
ment in determining when the lamps should be
switched on in response to ambient lighting
conditions.
For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks, you
should always switch on the lamps manually
under these conditions. ◀Seite 85LampsControls85

▷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

Page 107 of 292
▷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
