Indicator and warning lamps
The concept
The indicator and warning lamps can light up in
different combinations and colors.
Some lamps are tested for proper function by
briefly lighting up during starting of the engine
or when the ignition is switched on.
Explanatory text messages
Text messages at the upper edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
Additional information, e.g. on the cause of a
malfunction and on the corresponding need to
take action can be displayed via the Check Con-
trol, refer to page77.In the case of corresponding urgency, this infor-
mation is displayed immediately when the
related lamp lights up.

* and high-beam assistant*
If you open the driver's door with the ignition
switched off, the exterior lighting is automati-
cally switched off when the light switch is in
position0, 2 or 3.
If necessary, switch on the parking lamps,
switch position1.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine. It is better to switch on
the roadside parking lamps on one side, refer to
page104.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control*
In switch position3, the system activates the
low beams and switches them on or off in response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol
lights up when the low beams are on. You can
activate the daytime driving lamps, refer to
page103. In the situations named above, the
system then automatically switches over to the
low beams.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
low beams manually under these conditions.<
Welcome lamps
When parking the vehicle, if you leave the light
switch in position2 or3, the parking lamps and
the interior lamps light up briefly when the vehi-
cle is unlocked.

>Use the headlamp flasher as usual when the

System limits
The high-beam assistant cannot replace
personal judgment about the use of high
beams. In situations that require it, you should
therefore switch to low beams manually; failure
to do so can constitute a safety hazard.<
In the following sample situations, the system
will not function or will only function to a limited
degree, possibly requiring the driver to react
personally:
>in extremely unfavorable weather condi-
tions such as fog or heavy precipitation
>when you perceive poorly illuminated road
users such as pedestrians, cyclists, horse-
back riders, carriages, when rail or shipping
traffic is close to the road, or at deer cross-
ings
>in sharp curves, on steep hilltops or dips,
when there cross-traffic, or in the presence
of half-concealed oncoming traffic on the
highway
>in poorly lit areas and in the presence of
highly reflective signs
>in the low speed range
>when the windshield in the region of the
interior rearview mirror is fogged, dirty, or
covered by stickers, decals, etc.
>when the sensor is dirty. Clean the sensor
on the front side of the interior rearview mir-
ror with a cloth moistened with a little glass
cleaner.

stored for the remote control currently in use.
Fog lamps*
First, switch on the parking lamps or the low
beams. The green indicator lamp in the instru-
ment panel lights up whenever the fog lamps
are on.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
Instrument lighting
You can control the lighting intensity by using
the thumbwheel.
