Indicator and warning lamps
The concept
Indicator and warning lamps can light up both in
the display area1 and in the display2 in various
combinations and colors.
When the engine is started or the ignition is
switched on, some lamps are checked for
proper operation and light up briefly in the pro-
cess.
Explanatory text messages
Text messages at the bottom edge of the Con-
trol Display explain the meaning of the indicator
and warning lamps displayed.
You can consult Check Control for additional
information, e.g. regarding the cause of a mal-function or the appropriate actions to take, refer
to page64.
In cases of corresponding urgency, this infor-
mation is immediately displayed when the
associated lamps light up.

Alarm system
The concept
The vehicle alarm system responds:
>To the opening of a door, the hood, or the
luggage compartment lid
>To movements in the vehicle interior: inte-
rior motion sensor, refer to page35
>To changes in the vehicle's tilt if someone
attempts to steal the wheels or tow the
vehicle
>To interruptions in battery voltage
Unauthorized operations are briefly signaled by
the alarm system:
>by triggering an acoustic alarm
>by switching on
the hazard warning flashers
>by flashing the high beams
Arming and disarming alarm system
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
You can open the luggage compartment lid,
even with the system armed, by using the
button of the remote control, refer to page31.
When the luggage compartment lid is closed,
it is once again locked and monitored.
Switching off alarm
>Unlock the vehicle using the remote control,
refer to page30, or
>insert the remote control all the way into the
ignition lock.
Indicator lamp displays
>The indicator lamp below the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking: the
doors, hood or luggage compartment lid are
not properly closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx.
10 seconds. However, the interior motion
sensor is not activated.
>After the vehicle is unlocked, the indicator
lamp goes out: no manipulation or
attempted intrusions have been detected in
the period since the system was armed.
>The indicator lamp flashes after unlocking
until the remote control is inserted into the
ignition lock, however for a maximum of
approx. 5 minutes: an attempted entry has
been detected in the period since the sys-
tem was armed.
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if someone
attempts to steal the wheels or tow the vehicle.
Interior motion sensor
The condition for proper operation of the inte-
rior motion sensor is closed windows.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time.
This prevents unintentional alarms, e.g. in the
following situations:

Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking. For lighting on one
side for parking as an additional feature, refer to
page81.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, as otherwise it may no longer be
possible to start the engine.<
Low beams
The low beams light up in switch position2 only
with the engine running. Otherwise the parking
lamps are lit.
Automatic headlamp control
In the 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 is
illuminated when the low beams are on.When driving into a tunnel with bright overhead
lighting, switching on of the lights may be
delayed.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
If desired, the light switch can be left in
the position3. The exterior lighting is
automatically switched off after switching off
the vehicle.
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 system
cannot detect fog. To avoid safety risks, you
should always switch on the lamps manually
under these conditions.<
Pathway lighting
When you activate the headlamp flasher after
parking the vehicle and switching off the lamps,
the low beams will come on for a brief period.
You can set the duration or deactivate the func-
tion via iDrive.
iDrive, for explanation of principle, refer to
page16.

Daytime running lamps*
If desired, the light switch can remain in posi-
tion0, 1 or 3.
In position0 and 3 the exterior lighting is auto-
matically switched off after the vehicle is
switched off. In position1 the parking lamps
light up after the ignition is switched off.
Switch on the parking lamps if required as
described under Parking lamps.
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
In switch position3, the Adaptive Head Light is
active and the automatic headlamp control is
switched on, refer to page80.
To avoid blinding oncoming traffic, the Adaptive
Head Light is not active when driving in reverse
and points toward the passenger side when the
vehicle is stopped.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. The Adaptive Head Light
is malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps

2Headlamp flasher
3Roadside parking lamps
Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking. When using
this function, comply with national regulations.
Switching on
After parking the vehicle, press the lever in the
desired direction3, past the resistance point.
The roadside parking lamps drain the bat-
tery. Do not leave them switched on for
long periods of time, as otherwise it may no
longer be possible to start the engine.<
Switching off
Briefly press the lever in the opposite
direction3 up to the resistance point.
High-beam assistant*
The concept
This system automatically switches the high
beams on and off again. A sensor on the front of
the interior rearview mirror controls the pro-
cess. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. This reduces the strain on you
while at the same time providing you with the
best possible visibility. Of course, you can inter-
Lamps
82 vene at any time and switch the high beams on
and off in the accustomed manner.
Activating high-beam assistant
1.Turn the light switch to switch position3,
refer to page80.
2.Press the turn signal lever in the high beam
direction with the low beams switched on.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The assistant
automatically switches between high and low
beams, reacting to oncoming traffic and traffic
ahead and to well-lit areas such as towns and
cities.
Manually switching between high and
low beams
You can intervene at any time if you wish or the
situation requires.
>If the high-beam assistant has switched on
the high beams, but you want to use the low
beams, simply switch to the low beams with
the turn signal lever. This also deactivates
the high-beam assistant.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>If the high-beam assistant has switched on
the low beams, but you want to use the high
beams, switch to the high beams in the
accustomed manner. The system is deacti-
vated in the process and you must switch to
the low beams manually.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.>You use the headlamp flasher in the usual
way when the low beams are on.
System limits
The high-beam assistant cannot replace
personal decisions about the benefits of
using high beams. In situations that require
them, you should switch to the low beams man-
ually to avoid a safety risk.<
In the following sample situations, the system
either does not function or functions only in a
limited way and a personal reaction may be
required:
>Under extremely unfavorable weather con-
ditions, such as fog or heavy precipitation
>To make out poorly-lit road users such as
pedestrians, cyclists, people on horseback,
horse-drawn vehicles, train or ship traffic
close to the road and wild animals crossing
the road
>In tight curves, on steep hilltops or in
depressions, with cross traffic or partially
concealed oncoming traffic on the freeway
>In poorly lit places and with highly reflective
signs
>In the low speed range
>When the windshield is fogged up, dirty or
covered with stickers, decals, etc. in the
area of the interior rearview mirror
>When the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth moistened with a small
amount of glass cleaner
