2.Move foot in the direction of travel under‐
neath the bumper and immediately back.
The trunk lid opens, regardless of whether it was
previously locked or unlocked.
Malfunction
Comfort Access may not function properly if it
experiences interference from external sources
such as mobile phones, metal objects, overhead
power lines, transmission towers, etc.
In this case, open or close the vehicle using the
buttons on the remote control or use the
integrated key in the door lock.
If there is a malfunction, open the trunk lid with
the remote control button or with the button on
the trunk lid.
Alarm system
The concept
The vehicle alarm system responds to:
▷Opening of a door, the hood or the trunk lid.
▷Movements in the vehicle.
▷Changes in the vehicle tilt, e.g., during at‐
tempts to steal a wheel or when towing the
car.
▷Interruptions in battery voltage.
The alarm system briefly indicates tampering:
▷By sounding an acoustic alarm.
▷By switching on the hazard warning system.
▷By flashing the daytime running lights.
Arming and disarming the alarm
system
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 and armed alarm system
The alarm system is triggered when the door is
opened, if the vehicle is unlocked via the door
lock.
In order to terminate this alarm, unlock vehicle
with the remote control or switch on the ignition,
if necessary, by emergency detection of the re‐
mote control.
Trunk lid and armed alarm system
The trunk lid can be opened using the remote
control, even if the alarm system is armed.
Press the button on the remote control
for approx. 1 second.
After the trunk lid is closed, it is locked and
monitored again by the alarm system. The haz‐
ard warning system flashes once.
In some vehicle equipment variants, the trunk lid
can only be opened using the remote control if
the vehicle was unlocked first.
Panic mode
Press the button on the remote control
for at least 3 seconds.
Switching off the alarm
▷Unlock the vehicle using the remote control.
▷With Comfort Access: if you are carrying the
remote control with you, pull on the door
handle.
