Alarm systemThe conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened,
>To movement inside the vehicle
(interior motion sensor)
>To variations in the vehicle tilt sensor
such as those occuring during at-
tempts to steal the wheels or tow
the vehicle
>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
>Activating the hazard warning flash-
ers for approx. five minutes
>Flashing the high beams on and off in
sync with the hazard warning flashers.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
via a door lock or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.
The interior motion sensor and tilt alarm
sensor are activated approx. 30 sec-
onds after you have finished locking the
vehicle.
The system indicates that it has been
correctly armed by switching on the haz-
ard warning flashers for a single cycle
and by emitting an acoustical signal.
You can have different signals set
as acknowledgment messages for
arming and disarming.<
Indicator lamp displaysThe indicator lamp is located in the
inside rear view mirror's rotary knob.
>When the indicator lamp flashes con-
tinuously, the system is armed
>The indicator lamp flashes during
arming: the door(s), the hood or lug-
gage compartment lid are not com-
pletely closed. Even if you do not
close the alerted area, the remaining
areas are deadlocked, and the indi-
cator lamp flashes continuously after
10 seconds. However, the interior
motion sensor is not activated
>The indicator lamp goes out during
disarming: no manipulation or
attempted intrusions have been
detected in the period since the
system was armed520de014

Alarm system>If the indicator lamp flashes for
10 seconds when the system is dis-
armed, an attempted entry has been
detected in the period since the sys-
tem 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 to prevent a false alarm from being
triggered (in garages with elevator
ramps, for instance), or when the vehi-
cle is transported by trailer or train:
Lock the vehicle twice (= arm the sys-
tem) by pressing button 2 on the re-
mote control twice in succession (refer
to page 32), or lock the vehicle twice
with the key (refer to page 30).
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.
Interior motion sensorIn order for the interior motion sensor
to function properly, the windows and
the luggage compartment lid must be
closed.
Nevertheless, you should deactivate
the interior motion sensor (refer to the
previous column) if
>children or animals are left in the
vehicle
>windows should remain open.
For US vehicles only:
The interior motion sensor is not
installed on US models as it has not re-
ceived FCC (Federal Communications
Comission) approval.<

Electric power windowsTo open and close the windowsFrom ignition key position 1:
>Press the switch up to but not past
the pressure point:
As long as you continue to hold the
switch down, the window will either
lower or raise
>Press the switch briefly past the pres-
sure point:
The window moves automatically.
Tapping it again stops the opening
or closing action.
The window on the passenger
side cannot be closed with the
one-touch mode function.<520de015
Using switch number 2, you determine
which window is to be opened or
closed:
>Window on the driver side,
push the switch all the way to the left
>Window on the passenger side,
push the switch all the way to the
right
>To move both windows at the same
time, keep the switch in the center
position.
The switch on the passenger-side door
activates the window for that side
alone.
After the ignition has been switched off:
You can still operate the electric win-
dows for up to 15 minutes, provided
that no door has been opened. Because the power windows are
sealed at high pressure to prevent
wind noise when closed, a powerful
motor is required for efficient closing.
When closing the windows, always
ensure that they are not obstructed in
any way. Unsupervised use of these
systems can result in serious personal
injury. Remove the ignition key to deac-
tivate the electric power windows when-
ever you leave the vehicle. Never leave
the keys in the vehicle with unsuper-
vised children.
Never place anything that could obstruct
the driver's vision on or next to the
windows.<
To use the convenience mode via the
door lock or the remote control, refer to
pages 30 or 32.

The automatic convertible topWeather protectionThe fabric convertible top combines re-
liable protection from the elements with
simple, convenient operation. Here are
a few tips to ensure that you enjoy your
roadster.
It is advisable to close the convertible
top when the vehicle is parked. The
closed convertible top not only protects
the passenger compartment from un-
foreseeable damage from the weather,
it also provides a certain degree of theft
protection. Even if the convertible top is
closed, store your valuables only in the
locked luggage compartment.
To prevent damage, do not operate the
convertible top at temperatures at the
freezing point.Operate the convertible top only
when the vehicle is stationary,
otherwise the procedure will be inter-
rupted. Driving before the opening or
closing procedure has been properly
concluded can lead to either damage
or injury.
Make sure that no objects or people get
in the way while the convertible top is
opening or closing, so that no damage
or injuries occur.
The automatic operating procedure is
interrupted immediately if the button for
actuating the top is released. The pro-
cedure can be continued in the desired
direction by pressing this button.<
To open from insideFrom ignition key position 1:
If at all possible, only operate the con-
vertible top if the engine is running in
order to save on the battery.
Press and hold the switch in the "Open"
(1) direction until the opening procedure
has ended with the convertible top
being stored in the convertible top com-
partment and the indicator lamp on the
instrument cluster has gone out (refer to
page 16).
While the convertible top is in motion,
the indicator lamp will stay on. If the
opening procedure is not complete, the
indicator lamp will flash after you re-
lease the button.520de055

For maximum safety when adjusting the
seating position, please observe the
following:
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 passenger to remember). If you
do so, there is a risk that you will slide
under the safety belt in an accident,
thus reducing the protection provided
by the safety belt.<
Correct sitting postureTo 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 steer-
ing wheel at its highest point with your
arms slightly bent.
1 Backward/Forward adjustment
2 Cushion height
3 Backrest angle
Adjust the head restraint manually.
Move the seat backward only if
the backrest is first locked into
place. Whenever the backrest has been
flipped forward, moved back and sub-
sequently folded back into place, it
cannot lock, which can damage the
back of the backrest and the rear trim
panel.
Do not move a seat whose backrest has
been tilted too far back, otherwise, the
back of the backrest and the rear trim
panel could be damaged.<

Head restraints Seat backrest Belt guideAdjustments Upward: by pulling.
Downward: unlock by first pressing the
button located on the right under the
leather (arrow 1).
Head restraints reduce the risk
of spinal injury in the event of an
accident.
Adjust the head restraint so that its
center is approximately level with your
ears.<520de016
To unlockPull on the outermost edge of the strap
and tip the backrest forward.
The straps are located on the outer
sides of the backrests. On the passen-
ger seat straps are also located on the
inner side of the backrest.
Lock both backrests while driving,
otherwise there is a danger of an
unexpected movement causing an
accident.
Do not use the strap as a holder, e. g.
for newspapers or other items. This
could cause the backrests to unlock.<520de098
The strap for the belt guide can be
opened: release the push button.
Should it be necessary, this can relieve
the load or the access to the equipment
in the rear well.
For further information regarding load-
ing, refer to page 81.
Before each trip, insert the safety
belt into the strap for the belt
guide, otherwise, it will not hold
securely and become ineffective due
to a loosely worn safety belt.<520de099
