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: 
door(s) or luggage compartment lid are not 
completely 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.
>The indicator lamp goes out after unlocking: 
no manipulation or attempted intrusions 
have been detected in the period since the 
system was armed.
>After unlocking, the indicator lamp flashes 
until the key is inserted into the ignition 
lock, but will not do so for longer than 
roughly 5 minutes: an attempted entry has 
been detected in the period since the sys-
tem was armed.
Tilt alarm sensor and interior motion 
sensor
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
Coupe:
In order for the interior motion sensor to func-
tion properly, the windows and glass sunroof
* 
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 sensor, is armed 
even if the convertible top is open. Falling 
objects, e.g. leaves, can trigger false alarms, 
refer to Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor 
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following 
situations:
>In stacking garages
>When transporting on car-carrying trains
>When animals are to remain in the vehicle
Switching off the tilt alarm sensor and 
interior motion sensor
Press the   button on the remote control 
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 prevent chil-
dren from operating the power windows and 
injuring themselves.<

Wiper operation is controlled automatically as a 
function of the rain intensity. The rain sensor is 
located on the windshield, directly in front of the 
interior rearview mirror.
Activating rain sensor
Press button. The LED in the button lights up.

ired wiper activation.<
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 intervals.
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.
Do not use washers when the washer fluid res-
ervoir is empty, as otherwise the washer pump 
will be damaged.<
Windshield washer nozzles
The windshield washer nozzles are automati-
cally heated in ignition key position 2.
Washer fluid
Washer fluid antifreeze is flammable. 
Always keep it well away from sparks and 
open flames, and store it in tightly closed con-
tainers well out of the reach of children. Always 
observe the instructions for use provided on the 
containers.<
Washer fluid reservoir
Capacity approx. 5.3 US quarts/5 liters
Fill with water and – if required – with a washer 
antifreeze, according to manufacturer's recom-
mendations.
In order maintain the mixture ratio, mix 
the washer fluid before filling.<
Cruise control
The concept
The cruise control is available for use at speeds 
of approx. 20 mph/30 km/h and higher. The 
vehicle maintains and stores the speed that you 
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g.when driving on winding roads, 
in heavy traffic or in poor road conditions such 
as snow, rain, ice, and loose road surface.<
