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.
Indicator lamps without text messages
The following indicator lamps notify you that 
certain functions are active:

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.

Sports Wagon: opening and closing the 
rear window
Small items can be loaded and unloaded 
quickly when the rear window is opened sepa-
rately.
When the button on the roller cover is 
pressed, refer to page115, the roller 
cover is raised. Before closing the rear window, 
press the roller cover downward until it 
engages.<
Press the button: the rear window opens 
slightly. It can now be swung upwards.
Press the window shut to close it.Make sure that the corners of any pointed 
or sharp-edged cargo are padded if they 
could bump against the rear window while the 
vehicle is in motion; otherwise, the heating ele-
ments of the rear window could be damaged.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the trunk lid/tail-
gate is opened
>To movements inside the vehicle: Interior 
motion sensor, refer to page34
>When the car's inclination changes, for 
instance if an attempt is made to jack it up 
and steal the wheels or to raise it prior to 
towing away
>When there has been an interruption of 
power supply from the battery
The alarm system signals unauthorized entry 
attempts for a short time by means of:
>An acoustic alarm
>Switching on the hazard warning flashers
>Flashing the high beams
Arming and disarming
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 trunk lid/tailgate even when 
the alarm system is armed, by pressing the 
button on the remote control, refer to 
page28. The lid is locked and monitored again 
as soon as you close it.
Panic mode*
You can trigger the alarm system if you find 
yourself in a dangerous situation:
Press the  button for at least three seconds.
To switch off the alarm: press any button.

1Parking lamps and daytime running lights
2Low-beam headlamps and welcome lamps
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.
