Alarm system
The concept
The vehicle alarm system responds:
>When a door, the hood or the trunk lid is 
opened
> To movements inside the vehicle: Interior 
motion sensor, refer to page 37
> 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

Arming and disarming
General information
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.
Door lock with armed alarm system
In some national-market versions, unlocking via 
the door lock triggers the alarm.
To switch off this alarm, unlock the vehicle with 
the remote control or switch on the ignition.
Trunk lid with the alarm system armed
The trunk lid can be opened via the remote con-
trol even when the alarm system is armed.
Press the  button on the remote control for 
approx. 1 second.
The trunk lid is locked and monitored again as 
soon as it is closed.
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.
Switching off an alarm
>Unlock the car with the remote control, refer 
to page 32.
> Insert the remote control all the way into the 
ignition lock.
Indicator lamp on inside mirror
>The indicator lamp flashes continuously:
The system is armed.
> The indicator lamp flashes after locking:
The doors, hood, or trunk lid are not prop-
erly closed, the remaining components are 
secured.
Then the indicator lamp flashes continu-
ously after approx. 10 seconds. The interior 
motion sensor and tilt sensor are not active.
> The indicator lamp goes out after unlocking:
The vehicle has not been tampered with.
> If the indicator lamp flashes after unlocking 
until the remote control is inserted in the 
ignition, but for no  longer than approx. 
5minutes: 
The vehicle has been tampered with.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm 
system reacts, e.g. to attempts to steal a wheel 
or tow the vehicle.
Interior motion sensor
Coupe
For proper function, the windows and glass 
sunroof must be closed.
Convertible
The interior of the car is monitored up to the 
height of the seat cushions. Thus the alarm sys-
tem is activated together with the interior 
motion sensor even if the hardtop is open. The 
alarm can be triggered unintentionally by falling

ControlsOpening and closing
objects such as leaves, refer to Avoiding unin-
tentional alarms.
Avoiding unintentional alarms
The tilt sensor and interior motion sensor can 
be deactivated together, for example in the fol-
lowing situations:
>In car washes
> In stacking garages
> During transport on car-carrying trains, 
boats/ships or on a trailer
> When leaving animals in the vehicle
Switching off tilt alarm sensor and 
interior motion sensor
Once the vehicle is locked, press the   
button on the remote control again within 
approx. 10 seconds.
The indicator lamp lights up briefly and then 
flashes continuously. The tilt alarm sensor and 
the interior motion sensor are switched off until 
the next time the vehicle is unlocked and subse-
quently locked again.
Comfort Access
The concept
It is possible to access the vehicle without actu-
ating the remote control. It is sufficient to have 
the remote control with you, for example in your 
jacket pocket. The vehicle automatically 
detects the remote control in the vicinity or in 
the passenger compartment.
Comfort Access supports the following func-
tions:
>Unlocking/locking the vehicle
> Convenient closing
> Unlocking the trunk lid separately
> Engine starting
Functional  requirement
>There are no external sources of interfer-
ence in the vicinity.
> The remote control must be outside the 
vehicle to lock it.
> The next unlocking and locking cycle is not 
possible until after approx. 2 seconds.
> It is only possible to start the engine if the 
remote control is inside the vehicle.
Comparison to the standard remote 
control
The above functions can be controlled by 
pressing the remote control buttons or by using 
Comfort Access.
If you notice a brief delay while opening or 
closing windows, the glass roof or retract-
able hardtop, the system is checking whether a 
remote control is inside the vehicle. Please 
repeat the opening or closing procedure, if nec-
essary. <
Unlocking
Grasp the handle on the driver's or front pas-
senger door completely, arrow  1.
This corresponds to pressing the  button.
Locking
Touch the surface on the door handle, arrow  2, 
with your finger for approx. 1 second.
This corresponds to pressing the   but-
ton.

danger that the fluid will freeze on the 
windshield. If you do, your vision could be 
obscured. Antifreeze should therefore be 
added to the fluid, refer to Washer fluid. 
Do not use the washers when the washer fluid 
reservoir is empty; otherwise, you will damage 
the washer pump. <
Windshield washer nozzles
Both windshield washer nozzles are automati-
cally heated with the engine running or the igni-
tion switched on.
Washer fluid
Washer fluid antifreeze is flammable. 
Therefore, keep it away from ignition 
sources and only store it in the closed original 
container that is kept out of reach of children; 
otherwise, there is a risk of personal injury. 
Comply with the instructions on the con-
tainer.<
Washer fluid filler neck
Only refill washer fluid when the engine is 
cool to avoid contact with hot engine 
parts. Otherwise, fluid spills constitute a fire 
hazard and a risk to personal safety. <
