Indicator and warning lamps
The concept
Indicator and warning lamps can light up in a 
variety of combinations and colors.
Several of the lamps are checked for proper 
functioning and light up temporarily when the 
engine is started or the ignition is switched on.
Text messages
Text messages at the top edge of the Control 
Display describe the meanings of the indicator 
and warning lamps.
Supplementary text messages
You can call up more information on the Control 
Display, e.g. on the cause of a malfunction and 
on how to respond, via Check Control, refer to 
page80.
In urgent cases, this information will be shown 
as soon as the corresponding lamp comes on.

Central locking system
The concept
The central locking system functions when the 
driver's door is closed.
The system simultaneously engages and 
releases the locks on the following:
>Doors
>Trunk lid/tailgate
>Fuel filler flap
Operating from outside
>Via the remote control
>Via the door lock
*
>In cars with Comfort Access*, via the 
handles on the driver's and front passenger 
doors
In addition, if the remote control is used, the 
interior lamps and the door's courtesy lamps
* 
are also switched on or off. The alarm system* 
is also armed or disarmed.
For further details of the alarm system,
 refer to 
page33.
Operating from inside
By means of the button for central locking, 
refer to page30.
In the event of a sufficiently severe accident, 
the central locking system unlocks automati-
cally. In addition, the hazard warning flashers 
and interior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle 
could lock the doors from the inside. You 
should therefore take the remote control with 
you when you leave the vehicle so that the latter 
can be opened from outside.<
Unlocking
Press the  button.
The interior lamps, the courtesy lamps
* and the 
welcome lamps come on.

3Automatic headlamp control
*, daytime run-
ning lights, welcome lamps, high-beam 
assistant
* and adaptive light control*
When you open the driver's door with the igni-
tion switched off, the exterior lighting is auto-
matically switched off if the light switch is in 
position 0, 2 or 3.
Switch on the parking lamps if necessary, 
switch position 1.
Parking lamps
In switch position1, the front, rear and side 
vehicle lighting is switched on. You can use the 
parking lamps for parking.
When the ignition is switched off and the switch 
is in position 1, only the outside sections of the 
rear lamps are illuminated, refer to page241.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for 
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the 
engine. It is preferable to switch on the left-
hand or right-hand roadside parking lamps, 
refer to page99.<
Low beams
The low beams light up when the light switch is 
in position 2 and the ignition is on.
Automatic headlamp control*
When the switch is in position3, the low beams 
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel, 
in twilight, or if there is precipitation. The adap-
tive light control
* is active. The LED next to the 
symbol is illuminated when the low beams are 
on. You can also activate the daytime running 
lights, refer to page98. In the situations 
described above, the lamps then automatically 
switch from daytime running lights to low 
beams.
The headlamps may also come on when the 
sun is sitting low on a blue sky.
The low beams remain switched on 
regardless 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 system 
cannot detect fog or hazy weather. To avoid 
safety risks, you should always switch on the 
low-beam headlamps manually under these 
conditions.<
Welcome lamps
If you leave the light switch in position 2 or 3 
when you park the car, the parking lamps and 
the interior lamps light up briefly when you 
unlock the vehicle.

Adaptive light control*
The concept
Adaptive light control 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 Light Control
With the ignition switched on, turn the light 
switch to position 3, refer to page97. 
Standstill function
*: to avoid blinding oncoming 
traffic, the adaptive light control directs light 
towards the front passenger side when the 
vehicle is at a standstill.
Adaptive light control is not active when revers-
ing.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive light control is 
malfunctioning or has failed. Have the system 
checked as soon as possible.

High beams/roadside parking 
lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
*
Roadside parking lamps, left or right*
There is an additional option of switching on the 
lamps on the side of the car facing the road 
when parked.
Switching on
After parking the vehicle, press the lever up or 
down beyond the pressure point for a longer 
period, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for 
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the 
engine.<
Switching off
Press the lever in the opposite direction to the 
pressure point, arrow 3.
High-beam assistant*
The concept
This system automatically switches the high 
beams on and off. The procedure is controlled 
by a sensor on the front of the interior rearview 
mirror. The assistant ensures that the high 
beams are switched on whenever the traffic sit-
uation allows. It handles this task for you and 
gives you the benefit of the best possible view. You can intervene at any time and switch the 
high beams on and off as usual.
Activating the system
1.Turn the light switch to position3, refer to 
page97.
2.With the low beams switched on, briefly 
push the turn indicator lever in the direction 
of the high beam.
The indicator lamp in the instrument 
cluster lights up when the high beams 
are activated. The system automati-
cally switches from high beams to low beams 
and vice versa in response to oncoming traffic, 
traffic ahead of you, and adequate ambient 
lighting, e.g. on city streets.
Switching the high beams on and off 
manually
Whenever you wish, or when the situation 
requires, you can intervene:
>If the high-beam assistant switches on the 
high beams, but you would like to drive with 
the low beams, simply switch off the high 
beams using the turn indicator lever. This 
deactivates the high-beam assistant. 
To reactivate the system, briefly push the 
turn indicator lever toward the high beams 
again.
>If the high-beam assistant switches on the 
low beams, but you would like to drive with 
the high beams, switch on the high beams 
as usual. This deactivates the system and 
the high beams need to be switched off 
manually, if necessary.
To reactivate the system, briefly push the 
turn indicator lever toward the high beams 
again.
>Use the headlamp flasher as usual with the 
low beams switched on.

System limitations
The high-beam assistant cannot serve as 
a substitute for the driver's personal judg-
ment of when to use the high beams. Therefore, 
manually switch off the high beams in situations 
where this is required to avoid a safety risk.<
The system is not fully functional in situations 
such as the following, and driver intervention 
may be necessary:
>In very unfavorable weather conditions, 
such as fog or heavy precipitation
>In detecting poorly-lit road users, such as 
pedestrians, cyclists, horseback riders and 
wagons; when driving close to train or ship 
traffic; and at animal crossings
>In tight curves, on hilltops or in depressions, 
in cross traffic or half-obscured oncoming 
traffic on highways
>In poorly lit towns and cities and in the pres-
ence of highly reflective signs
>At low speeds
>When the windshield in front of the interior 
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
>If the sensor is dirty. Clean the sensor on 
the front of the interior rearview mirror using 
a cloth moistened with a small amount of 
glass cleaner.

Fog lamps
The parking lamps or low beams must 
be switched on for the fog lamps to 
operate. The green indicator lamp in 
the instrument cluster lights up whenever the 
fog lamps are on.
The fog lamps are switched off while you acti-
vate the headlamp flasher or switch on the high 
beams.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
