Luggage compartment Alarm system
*
When opening the convertible top,
refer to page 45, make sure that
the luggage compartment is set up
properly, as otherwise damage may
occur.<
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid is opened
>To movement inside the vehicle (inte-
rior motion sensor)
>Altering the vehicle tilt angle, e. g. as
would occur while attempting to steal
the wheels or tow the vehicle (tilt
alarm sensor)
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
the same rhythm.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or with the remote
control, the alarm system is also simul-
taneously armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have
locked the vehicle.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both setting
and deactivating the alarm.<
You can also open the luggage
compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 37). When
it is closed, the lid is once again
secured.

Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed
>If the indicator lamp flashes while the
system is being set: the door(s), the
hood or luggage compartment lid are
not completely closed. Even if you do
not close the alerted area, the
remaining areas are deadlocked, and
the indicator lamp flashes continu-
ously after 10 seconds. However, the
interior motion sensor is not activated
>If the indicator lamp goes out when
the system is disarmed: no manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed
>If 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 any
unwanted alarm, e. g. in garages with
elevator ramps or when the vehicle is
being transported on car trains:
Lock the vehicle twice (= setting the
alarm): press button 2 on the remote
control twice in succession or lock the
vehicle twice with the key. Refer to
page 36.
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. Reset the alarm to reactivate
the tilt alarm sensor and the interior
motion sensor.
Interior motion sensorTransmitter and receiver for the interior
motion sensor are located in the front
part of the center console, invisible to
the driver, and in the back part of the
center console under a rack.
However, be sure to deactivate the
interior motion sensor (see previous
column) if children or animals are to
remain in the vehicle.

The fully automatic convertible top
combines assured protection from the
weather together with simple and easy
handling.
So that you will get the most out of your
convertible, here are a few tips:
>It is advisable to close the convertible
top when the vehicle is being parked.
The closed convertible top not only
protects the passenger compartment
from unforeseeable damage from the
weather, it also provides a certain
degree of theft protection. In addi-
tion, keep valuables only in the
locked luggage compartment, even
with the convertible top closed.
>Never mount a roof-mounted luggage
rack on the convertible top.
>At temperatures below 15 7
(–10 6) do not open or close the
convertible top to prevent damage.
Never store the convertible top
while it is wet to avoid permanent
damage from moisture.<
Driving the vehicle before the top
has opened or closed completely
can lead to vehicle damage and/or
personal injury.
Whenever possible, always ensure that
the vehicle remains stationary for the
entire duration of the opening/closing
process. Setting the vehicle in motion
before the process is completed may
cause the top to stop moving prema-
turely.
If you initiated convertible top operation
while the vehicle was standing still, and
then started to drive off, at a traffic light,
for example, you can complete the
process while traveling at a moderate
rate of speed. To do this, keep pressing
the proper button.
Traffic laws applicable in your area take
precedence when you operate the
convertible top, however, otherwise
you may be breaking the law.
Before closing the convertible top,
remove any objects from the windshield
frame that could keep the convertible
top from closing properly.
Do not lay objects on the convertible
top, since they would fall off when the
convertible top is operated and cause
damage or injuries.
Do not reach into the convertible top
mechanism during opening and closing.

Convertible topKeep children away from the travel path
of the convertible top while it is in
motion.<
To close the electric power
windows while driving, always be
sure to first close either the rear
windows, or all 4 windows at the same
time, otherwise, at high speed, the
windows may not close tightly.<
At higher speeds, the ensuing
vacuum in the passenger
compartment can cause the convertible
top to begin fluttering. Increase the air
supply via the ventilation controls so
that a vacuum does not occur in the
vehicle.<

Convertible top
During convertible top operation
the rear window moves toward the
passenger compartment and presses
the heads of the rear passengers
slightly forward. As a rule, this is not
dangerous. To avoid possibly being
pinched, passengers in the back seat
should lean their heads slightly forward
while the convertible top is in motion.<
The side windows move downward
somewhat when the button for convert-
ible top operation is pressed, and then
up again after the opening or closing
operation is completed if you continue
to hold the button for longer than
2 seconds after the indicator lamp goes
out.
During convertible top operation the
luggage compartment lid cannot be
opened.
Do not close the side power
windows using the buttons if the
convertible top has been interrupted
while in motion. <
If the convertible top has been
stored in the convertible top
compartment for longer periods, e.g.
during the winter months while the
hardtop is being used, it may be neces-
sary to manually support the first auto-
matic closing operation: if the
convertible top should halt just before
the closing phase is completed, press
against the front part of the convertible
top frame from the outside to help the
closing process along. Keep pressing
the button while doing so until the top
starts up again on its own.<
If the opening or closing operation
is interrupted, the convertible top
remains in the respective position for
15 minutes, and the process can be
continued in the desired direction with
the button. Then the convertible top
can be moved and operated manually,
refer to page 162. This is also possible
in ignition key position 0.
In certain cases, the luggage compart-
ment lid cannot be opened if the
opening or closing operation has been
interrupted.<
One-touch operation from the
driver side door lockRefer to page 34.

For your personal safety when adjusting
the seat position, please follow the
instructions below carefully:
Never try to adjust your seat while
driving the vehicle. The seat could
respond with an unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident.
Be sure that the safety belt remains
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over the hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced
if the belt is worn loosely.
Never ride with the backrest reclined to
an extreme angle (especially important
for the front passenger to remember). If
you do so, there is a risk that you will
slide under the safety belt in an acci-
dent, thus reducing the protection
provided by the safety belt.<
Correct sitting posture To reduce strain on the spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
The ideal sitting posture is achieved
with your head extending from your
spine in a straight line.
For long-distance driving, you may wish
to increase the backrest tilt angle
slightly to reduce muscular tension. You
should be able to grasp the steering
wheel at its highest point with your
arms slightly bent.
