Indicator/warning lights
The principle

Several of the lights are checked for proper
functioning when the engine is started or the
ignition is switched on, and light up briefly.
Text messages
Text messages at the upper edge of the Control
Display explain the meaning of the displayed
indicator and warning lights.

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 lights if necessary, switch
position 1.
Parking lights
Switch position 1: the vehicle lights light up on
all sides.
Do not use the parking lights for extended peri‐
ods; 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 lights, refer to
page 79.
Low beams Switch position 2: the low beams are lit when
the ignition is switched on.
Automatic headlight 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 lights.Seite 78CONTROLSLamps78
Online Edition for Part no. 01 40 2 964 459 - VI/15
The exterior lighting goes out automatically af‐
ter the vehicle is switched off.
System limits
The automatic headlamp control cannot serve
as a substitute for your personal judgment of
lighting conditions.
For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks, you
should always switch on the lights manually un‐
der these conditions.

flasher
To assist in parking, the vehicle can be illumi‐
nated on one side; note the country-specific
regulations.
The roadside parking lights drain the battery.
Therefore, do not leave them on for unduly
long periods of time; otherwise, the battery
might not have enough power to start the en‐
gine.
Switching on the roadside parking light

ter the vehicle is switched off.
In switch position 1, the parking lights light up
after the ignition is switched off.
Activating/deactivating

ning lights is mandatory; for this reason, day‐
time running lights cannot be deactivated in
these cases.1."Settings"2."Lighting"3."Daytime running lamps"
Settings are stored for the remote control cur‐
rently in use.
Welcome lights If the light switch stays in switch position 2 or 3

Adaptive Light Control
The concept
Adaptive Light Control is a variable headlight
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐
rameters, the light from the headlight follows
the course of the road.
Activating
With the ignition switch on, turn the light switch
to position 3, refer to page 78.
To avoid blinding oncoming traffic, the Adap‐
tive Light Control does not swivel to the driver's
side when the vehicle is at a standstill.
When driving in reverse, Adaptive Light Control
is not active.
Malfunction The warning light lights up. A message
appears on the Control Display. Adap‐
tive Light Control is malfunctioning or
has failed. Have the system checked as soon as
possible.
Fog lights Overview
To switch on the front fog lights: press the
switch.
To switch off, press the respective switch up‐
ward or downward again.
Fog lights The parking lights or low beams must be
switched on. The green indicator lamp lights up
when the front fog lights are switched on.
Depending on the vehicle equipment, the front
fog lights are switched off when the headlight
flasher or the high-beams are activated.
If the automatic headlight control is activated,
refer to page 78, the low beams are switched
on automatically when the front fog lights are
switched on.
Instrument lighting The parking lights or low beams must be
switched on to adjust the brightness. The
brightness is increased to a certain limit and is then reduced again.

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.
WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible. ◀

tions. There is risk of an accident. Adjust the
driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀

DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the
work on the lighting system including bulb re‐
placement be performed by a dealer’s service
center or another qualified service center or re‐
pair shop. ◀
