Opening and closing
24 Manual operation of the tailgate triggers 
the alarm. Refer to page21.<
Switching off an alarm
>Unlock the car with the remote control, refer 
to page19.
>Turn the master key in the ignition lock to 
position 1, refer to page40.
Indicator lamp displays
>The indicator lamp beneath the interior mir-
ror flashes continuously:
The system is armed.
>The indicator lamp flashes immediately 
after the vehicle is locked: 
Doors, hood or luggage compartment lid/
tailgate are not properly closed. Even if you 
do not close the alerted area, the system 
begins to monitor the remaining areas, and 
the indicator lamp flashes continuously 
after approx. 10 seconds. However, the 
interior motion sensor is not activated.
>If the indicator lamp goes out immediately 
after the vehicle is unlocked:
Your vehicle has not been disturbed while 
you were away.
>If the indicator lamp flashes for 10 seconds 
immediately after the vehicle is unlocked: 
Your vehicle has been disturbed while you 
were away.
After an alarm has been triggered, the indicator 
lamp will flash continuously.
Tilt alarm sensor
The inclination of the vehicle is monitored. The 
alarm system reacts e.g. to attempts to steal a 
wheel or tow the vehicle.
Interior motion sensor*
Coupe
All windows must be closed in order for the inte-
rior motion sensor to function optimally.
Roadster
The system monitors the footwells and the 
seating areas of the driver and passenger. Even 
when the convertible top is open, the alarm sys-
tem including the interior motion sensor is 
armed. Objects falling into the vehicle, e.g. 
leaves, can trigger unintentional alarms, refer to 
Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor 
can be deactivated at the same time. In this way 
you can avoid unintentional alarms, e.g. in the 
following situations:
>In duplex garages
>When transporting the vehicle on car-carry-
ing trains, by ship or on a trailer
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and 
interior motion sensor
>Press the   button on the remote 
control twice in a row.
The indicator lamp lights up briefly and then 
flashes continuously. The tilt alarm sensor and 
the interior motion sensor are deactivated until 
the vehicle is again unlocked and locked.
Windows
To prevent injuries, exercise care when 
closing the windows and keep them in 
your field of vision until they are shut.
Take the key with you when you leave the car, 
otherwise children could operate the windows 
and possibly injure themselves.< 

Climate
66
Comfortable interior climate
AUTO program 6 offers the ideal air distribution 
and air flow rate for almost all conditions, refer 
to AUTO program below. In addition, you can 
select an interior temperature you find pleasant.
The following sections inform you in detail 
about how to adjust the settings.
Air distribution, manual
Direct the flow of air to the windows 
, to the upper body area   and to 
the footwell  . Intermediate settings 
are possible. The arrow lights up.
The automatic air supply remains unchanged. 
You can switch the automatic air distribution 
back on by pressing the AUTO button.
Defrosting windows and removing 
condensation
Quickly removes ice and condensa-
tion from the windshield and side 
windows.
AUTO program
The AUTO program adjusts the air 
distribution to the windshield and 
side windows, towards the upper 
body area and into the footwell for 
you. The air flow rate and your temperature 
specifications will be adapted to outside influ-
ences as a result of seasonal changes, e.g. sun-
light or window condensation.
The cooling is switched on automatically with 
the AUTO program.
The AUTO program functions only to a 
limited extent when the convertible top is 
open.<
Air flow rate, manual
Adjust the air flow rate. The arrow 
lights up.
The automatic air distribution 
remains unchanged. You can reactivate the 
automatic mode for the air flow rate with the 
AUTO button.The higher the air flow rate, the more effective 
the air conditioning will be.
Switching the system on/off
Turn the rotary switch to 0. The automatic cli-
mate control is switched off and the air supply is 
cut off.
To switch on the automatic climate control, set 
any desired air flow rate.
Switching cooling function on/off
When the cooling function is on, the 
air is cooled, dehumidified, then 
reheated depending on the tempera-
ture setting.
Depending on the weather, the windshield may 
fog over briefly when the engine is started.
The cooling function is automatically switched 
on along with the AUTO program. The passen-
ger compartment can only be cooled while the 
engine is running.
Maximum cooling 
At outside temperatures above 
327/06 and when the engine is 
running, you obtain a maximum cool-
ing effect as soon as possible.
The automatic climate control switches to the 
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only 
from the vents for the upper body area. You 
should therefore open them for maximum cool-
ing.
Temperature 
Set the desired temperature.
The values on the dial are approxima-
tions of the respective temperature 
resulting in the passenger compartment.
The automatic climate control achieves this 
temperature as quickly as possible regardless 
of the season, using maximum cooling or heat-
ing power if necessary, and then maintains it.
If you switch between different tempera-
ture settings in quick succession, the  

Refueling

Refueling
Always switch off the engine before refu-
eling. Otherwise the tank cannot be 
refilled. The Service Engine Soon warning lamp 
will come on.<
Take all precautionary measures and 
observe all applicable regulations when 
handling fuel. Do not carry any spare fuel con-
tainers in your vehicle. They can develop a leak

fully; otherwise it could be torn off.<
Observe the following when refueling
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. Avoid lifting the filler 
nozzle while filling the tank, as it could other-
wise lead to:
>Premature pump shutoff
>A reduced efficiency of the fuel-vapor 
recovery system.
