The antitheft alarm is automatically armed or disarmed
with the remote control or any of your vehicle’s keys by
locking or unlocking the vehicle.
The antitheft alarm is armed within approximately
10 seconds after locking the vehicle.
A blinking lamp (1) indicates that the alarm is armed.
Operation:
Once the alarm system has been armed, the exterior
vehicle lamps will flash and an alarm will sound when
someone:
•opens a door,
•opens the trunk,
•opens the hood,
•opens the glove box,
•attempts to raise the vehicle.The alarm will last approximately 3 minutes in form of
flashing exterior lamps. At the same time an alarm will
sound for 30 seconds. The alarm will stay on even if the
activating element (a door, for example) is immediately
closed. If the alarm stays on for more than 20 seconds,
an emergency call is initiated automatically. See Tele
Aid on page 130.

•do not permit luggage / cargo to raise the closed
luggage cover,
•do not load anything on top of the luggage cover,
•do not place anything on shelf behind roll bars.
Note:
To prevent the hardtop from being lowered
unintentionally while a roof luggage carrier is installed,
keep luggage cover in trunk in the open position.

Before operating the switch for the retractable
hardtop make sure that no persons due to
inattention are injured by the moving parts
(retractable roof, roof frame, and trunk lid).Hands must never be placed near the roof frame,
