40nAlarm system  
The concept  
To activate and deactivate the  
alarm system  
The vehicle alarm system responds:  
When the vehicle is locked or unlocked  
with the key or the remote control, the  
alarm system is also simultaneously  
armed or disarmed.  
> When a door, the hood or the  
luggage compartment lid is opened.  
> To movement inside the vehicle  
(interior motion sensor).  
The interior motion sensor is activated  
approx. 30 seconds after you have  
finished locking the vehicle.  
> to changing the vehicle's tilt if  
someone attempts to steal the  
wheels or tow the vehicle.  
> To an interruption in battery voltage.  
The system indicates that it has been  
correctly armed by switching on the  
hazard warning flashers for a single  
cycle and by emitting an acoustical  
signal.  
The system responds to unauthorized  
vehicle entry and attempted theft by  
simultaneously activating the following  
Indicator lamp displays  
> The indicator lamp below the interior  
rearview mirror flashes continuously:  
the system is armed.  
> Sounding an acoustical alarm for  
30 seconds.  
You can have various confirmation  
messages set to inform you that  
the alarm system has been armed or  
disarmed.<  
> The hazard warning flashers are acti-  
vated for approx. five minutes.  
> The high beams flash on and off in  
the same rhythm.  
> The indicator lamp flashes when it is  
armed: a door (or doors), the hood,  
luggage compartment lid or rear  
window is not completely closed.  
Even if you do not close the indicated  
area, the system begins to monitor  
the remaining areas, and the indi-  
cator lamp flashes continuously after  
10 seconds. However, the interior  
motion sensor is not activated.  
> The indicator lamp goes out when the  
system is disarmed: no manipulation  
or attempted intrusions have been  
detected in the period since the  
system was armed.  
You can still open the luggage compart-  
ment after the system has been armed  
by pressing button 3 of the remote  
control (refer to page 35). When you  
close the luggage compartment, the lid  
is secured again.  
 
Alarm system  
41n  
> The indicator lamp flashes for  
10 seconds when the system is  
disarmed: an attempted entry has  
been detected in the period since the  
system was armed.  
Following triggering of an alarm, the  
indicator lamp will flash continuously.  
Avoiding unintentional alarms  
The tilt alarm sensor and interior motion  
sensor may be switched off at the same  
time. You can do this to prevent a false  
alarm from being triggered (in garages  
with elevator ramps, for instance, or  
when the vehicle is transported by  
trailer or train):  
Interior motion sensor  
The illustration depicts the transmitter  
and receiver of the interior motion  
sensor.  
In order for the interior motion sensor to  
function properly, the windows and  
sliding/tilt sunroof must be completely  
closed.  
Actuate the lock (= arm the system)  
twice; in other words, press button 2 of  
the remote control twice in succession  
(refer to page 34). You may also actuate  
the lock twice with the key (refer to  
page 32).  
Nevertheless, you should deactivate  
the interior motion sensor (refer to the  
previous column) if the windows or  
sliding/tilt sunroof should be left open.  
The indicator lamp lights up briefly and  
then flashes continuously. The tilt alarm  
sensor and the interior motion sensor  
are deactivated as long as the system  
is armed.
