Indicator lamp displays 
>The indicator lamp below the interior 
rearview mirror flashes continuously: 
the system is armed
>The indicator lamp flashes on locking: 
door(s) or luggage compartment lid are 
not completely closed. Even if you do 
not close the alerted area, the system 
begins to monitor the remaining areas, 
and the indicator lamp flashes continu-
ously after approx.10 seconds. How-
ever, the interior motion sensor is not 
activated
>The indicator lamp goes out on unlock-
ing: no manipulation or attempted intru-
sions have been detected in the period 
since the system was armed
>The indicator lamp flashes on unlocking 
before the remote control is inserted in 
the ignition lock, but for no more than 
roughly 5 minutes: an attempted entry 
has been detected in the period since 
the system was armed.
Following triggering of an alarm, the indica-
tor lamp will flash continuously.
Tilt alarm sensor and interior motion 
sensor 
Tilt alarm sensor
Monitors the inclination of the vehicle. The 
alarm system reacts, for example, if some-
one attempts to steal the wheels or tow the 
vehicle.
Interior motion sensor 
Coupe:
In order for the interior motion sensor to 
function properly, the windows and glass 
roof must be completely closed.
Convertible:
Monitors the interior up to the height of the 
seat cushions. This means that the alarm 
system, including the interior motion sen-
sor, is armed even if the convertible top is 
open. Falling objects, e.g. leaves, can trig-
ger false alarms, refer to Avoiding uninten-
tional alarms.
Avoiding unintentional alarms 
The tilt alarm sensor and interior motion 
sensor may be switched off at the same 
time. This is how you prevent unintentional 
alarms, e.g. in the following situations:
>In garages with elevator ramps
>During transport on automobile trans-
port trains
>If animals are to remain in the vehicle.
Switching off tilt alarm sensor and 
interior motion sensor 
Press the   button on the remote con-
trol once again directly after locking.
The indicator lamp lights up briefly and 
then flashes continuously. The tilt alarm 
sensor and the interior motion sensor are 
switched off until the vehicle is unlocked 
and locked again.
Windows 
To prevent injuries, exercise care 
when closing the windows and keep 
them in your field of vision until they are 
shut.
When leaving the vehicle, always remove 
the ignition key and close the doors to pre-
vent children from operating the windows 
and injuring themselves etc.<

4Cleaning windshield and headlamps 
5Adjusting rain sensor sensitivity level 
The lever automatically returns to its initial 
position when released. 
Cleaning windshield and headlamps 
The system sprays washer fluid against the 
windshield and activates the wipers for a 
brief period. 
When the vehicle lighting system is 
switched on, the headlamps are also cleaned at regular and appropriate inter-
vals. 
Do not use the washers if there is  any 
danger that the fluid will freeze on the 
windshield. If you do so, your vision could 
be obscured. To avoid freezing, use a 
washer fluid antifreeze, refer to Washer 
fluid. 
Avoid activating the washer when the res-
ervoir is empty, as damage to the pump 
could result.<
Windshield washer nozzles 
The windshield washer nozzles are auto-
matically heated in ignition key position 2. 
Rain sensor 
The rain sensor controls windshield wipe 
operation depending on the amount of rain. 
The rain sensor is located on the wind-
shield, directly in front of the interior rear-
view mirror. 
Activating rain sensor 
As of ignition key position 1, briefly press 
the button. The indicator lamp in the button 
lights up. The wipers will always respond 
by completing at least one sweep of the 
windshield. 
Adjusting rain sensor sensitivity level 
Turn the serrated dial 5. 
Deactivating rain sensor 
Press the button again. The indicator lamp 
goes out. 
The rain sensor is automatically deacti-
vated when you switch off the ignition.  

A congenial climate
90 rently within the vehicle. AUC executes this 
function automatically.
Press the button repeatedly to run through 
the following control sequence:
>Indicator lamps off: outside air flows 
into the vehicle continuously
>Right indicator lamp on, AUC mode: the 
system detects pollutants in the outside 
air and responds by blocking the supply 
of outside air when required.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air 
and recirculated-air modes
>Left indicator lamp on, recirculated-air 
mode: the supply of outside air into the 
vehicle is continuously blocked.
If condensation starts to form on the 
inside window surfaces during opera-
tion in the recirculated-air mode, you 
should switch it off while also increasing 
the air volume as required.
The recirculated-air mode should not be 
used over a longer period of time, as the air 
quality inside the vehicle deteriorates con-
tinuously.<
Residual heat mode 
If you press this button with the 
engine switched off, the system 
uses the warmth stored in the 
engine to heat the interior, for 
instance, while the vehicle is 
stationary at a school to pick up a child.
You can adjust the automatic climate con-
trol settings as of ignition key position 2.
Provided that the engine has warmed to its 
normal operating temperature and the bat-
tery is charged, you can use this function 
for up to 15 minutes after switching off the 
ignition. The LED within the button lights up 
to confirm compliance with both of these 
conditions.
Switching off automatic climate 
control 
The air volume, the heater and 
the cooling function are all 
switched off. You can restart 
the automatic climate control 
by pressing any of its buttons 
except the REST button.
