1.Read and comply with the preceding
safety precautions
2.Make sure that the convertible top com-
partment panel in the luggage compart-
ment is lowered; refer to page 22. Oth-
erwise the convertible top cannot be
opened
3.Ensure that the luggage compartment
lid is closed
4.Press and hold the corresponding but-
ton for convertible top operation.
If the convertible top should halt right
before the closing phase is completed,
press against the front part of the convert-
ible 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.
Indicator lamps
>The red indicator lamp will light up while
the convertible top is in motion. It goes
out as soon as the opening or closing
operation has been completed
>If the red indicator lamp flashes after
the button has been released, then the
opening or closing operation has not
yet been completed.
The sequence can be continued in the
desired direction by pressing this but-
ton
>If the yellow indicator lamp lights up
continuously with the button pressed,
then the convertible top compartment
panel is raised and the convertible top
cannot be moved.
The side windows will lower slightly when
you press the button for operating the con-
vertible top.
After the opening or closing operation, the
side windows will go back up if you keep
the button pressed for more than 2 sec-
onds after the indicator lamp has gone out.
The automatic sequence will be interrupted
immediately if you release the button that
operates the top. The sequence can be continued in the desired direction by press-
ing this button.
If the convertible top operation has
been interrupted, do not close the
side windows using the power window but-
tons. Otherwise the side windows may not
close properly against the rubber seal of
the convertible top.<
After the convertible top has been
stored for an extended period of time
in the convertible top compartment – e.g. in
the winter months because the hardtop
was being used – you may have to support
the convertible top by hand when closing it
for the first time.<
If the opening or closing procedure has
been interrupted due to an electrical mal-
function, the convertible top will remain in
that position for 15 minutes. The procedure
can be resumed in the desired direction by
pressing the button. After that, the convert-
ible top can be moved again and, if it is an
emergency situation, you may have to help
the top along manually. This can also be
done in ignition key position 0.

vided on the rollover bars.
The wind deflector panels inserted in the
rollover bars cannot be removed.
Clothes hooks

rollover bars.
Do not hang heavy objects on the

Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage
compartment lid is opened
>When attempts are made to start the
vehicle
>To movement inside the vehicle – inte-
rior motion sensor
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal
the wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the
event of unauthorized vehicle entry and
attempted theft depends on the country
version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flash-
ers for approx. five minutes.
Arming and disarming the alarm sys-
tem
When the vehicle is locked or unlocked
either via the driver's door lock or with the
remote control, the alarm system is simul-
taneously armed or disarmed.The hazard warning flashers blink once
when the alarm system has been properly
armed.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can open the luggage compartment lid
when the system is armed by pressing the
remote control button. Refer to page 19.
When it is closed, the lid is once again
secured.
Manual operation of the luggage
compartment lid triggers the alarm.
Refer to page 21.<
To cancel an alarm:
Press the button on the remote control,
refer to page 18, or turn the ignition key to
position 1. Refer to page 38.
Indicator lamp displays
>The indicator lamp beneath the interior
mirror flashes continuously:
The system is armed
>The indicator lamp flashes when it is
being armed:
A door, the hood or luggage compart-
ment lid is not completely closed. Even
if you do not close the area causing the
alert, the remaining areas are secured
and the indicator lamp flashes continu-
ously after 10 seconds.
However, the interior motion sensor is
not activated

If you make use of this method of
adjustment, be sure that the space
behind the driver's seat is unobstructed
before unlocking the vehicle. If you fail to
do so, objects behind the seat could be
damaged by a rearward movement of the
seat.<

Steering locked
This is the only position in which the igni-
tion key can be inserted or removed.
After removing the key, turn the steering
wheel slightly to the left or right until the
lock engages.
If the key is not removed, an acoustic signal
sounds when the driver's door is opened.
Once the ignition has been switched off –
ignition key in position 0 or removed – the
radio functions are still available for approx.
20 minutes. Turn the radio back on to use it.
Vehicles with automatic transmission:
do not move the selector lever from
position P until the engine is running – igni-
tion key in position 2.
In order to turn the key back to position 0 or
to remove it, move the selector level into
position P first – Interlock.<
Steering unlocked
You will often find that it is easier to turn the
ignition key from position 0 to 1 if you move
the steering wheel slightly to help disen-
gage the detent.
Individual electrical equipment and acces-
sories are available for use.
Engine
Do not allow the engine to warm up while
the vehicle is stationary. Instead, begin
driving immediately at a moderate engine
speed.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and should
decrease as the engine warms up. If engine
speed does not decrease, service is
required.
To prevent the battery from discharging,
always deactivate electrical devices that
are not in use. Switch the ignition off when
the vehicle is not being driven.
Do not allow the engine to run in
enclosed spaces. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas. Breathing
the exhaust gases poses an extreme health
risk, and can lead to unconsciousness and
death.
Do not leave the vehicle unattended with
the engine running. An unattended vehicle
with a running engine poses a safety haz-
ard.
When driving, standing at idle and parking
the vehicle, take care to avoid contact
between the hot exhaust system and flam-
mable materials – e.g. hay, leaves, grass,
etc. Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
Starting the engine
Do not press the accelerator pedal while
starting the engine.
Vehicles with manual transmission:
Step on the clutch when starting the
vehicle. A lockout prevents the engine from
starting if the clutch is not depressed.<
Do not actuate the starter for too
short a time, but do not actuate it for
more than approx. 20 seconds. Release

Tank capacity: approx. 14.5 gallons /
55 liters, of which approx. 2.1 gallons /
8 liters are reserve capacity.
Simple and environmentally friendly
When handling fuels, comply with all
of the applicable safety precautions
posted at the service station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Pulling the nozzle
out of the pipe during refueling
>results in premature shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full when the filler nozzle
shuts off the first time.
Fill the fuel tank before it is com-
pletely empty. Driving to the last drop
of fuel can prevent the engine from operat-
ing properly and result in damage.<
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index.
Do not use leaded fuels. The use of
leaded fuels will cause permanent
damage to the system's oxygen sensor and
the catalytic converter.<
