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.<
Opening, closing
Ignition key in position 1 or higher:
>Press the switch downward to the resis-
tance point.
The window continues to open as long as 
you press the switch.
>Press the switch beyond the resistance 
point.
The window opens automatically. Press the 
switch again to stop the opening move-
ment.
You can close the window in the same manner 
by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After switching off the ignition
You can still open or close the windows for 
approx. 1 minute, as long as no one opens any 
of the doors.
For convenience operation via the remote con-
trol or the door lock, refer to page19 or20, 
respectively.
Pinch protection system
If the closing force exceeds a certain value while 
a window is being raised, the system responds 
by stopping the window and then retracting it a 
short distance.
Despite the pinch protection system 
check and clear the window's travel path 
prior to closing it, otherwise the safety system 
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window 
would continue closing. 
Do not install any accessories within the win-
dows' range of movement; otherwise the pinch 
protection system could be impaired.<
The closing force can change as a result 
of extreme temperature fluctuations. The 
window then opens slightly after closing even if 
there is no obstacle within the window's travel 
path. If this occurs, override the pinch protec-
tion system.<
Pulling the switch beyond the resistance point 
and holding it there overrides and deactivates 
the pinch protection system.
After a power supply interruption
After a power supply interruption, for instance 
after disconnecting the battery, the pinch pro-
tection system must be reinitialized.
Roadster: when the convertible top has 
been stored in the convertible top com-
partment for an extended period of time, e.g. in 
the winter months because the hardtop was 
being used, it may also be necessary to reinitial-
ize the pinch protection system.<
Ensure that the doors and the Roadster's con-
vertible top are closed before initializing. 

Lamps
56 You can have daytime running light acti-
vated/deactivated on your vehicle.<
Pathway lighting
If you activate the headlamp flasher after park-
ing the car, with the lights switched off, the low 
beams come on and remain on for a certain 
time.
You can have this function activated/
deactivated as well as the duration of the 
pathway lighting set.<
LIGHTS ON warning
Whenever you open the driver's door after hav-
ing turned the key to position 0, you will hear an 
acoustic signal for a few seconds to remind you 
that the lamps have not been switched off.

Roadside parking lamps, left or right*
When parking the vehicle, you have the option 
to switch on the lamps only on the side facing 
the road.
After parking the vehicle, press the lever up or 
down, arrow 3, until it engages.
The roadside parking lamps discharge 
the battery. Therefore, do not leave them 
on for unduly long periods of time, otherwise 
the battery might not have enough power to 
start the engine.<
Fog lamps*
Press the button to switch them on/off.
The parking lamps or low-beam headlamps 
must be switched on. A green indicator lamp 
comes on in the instrument cluster to indicate 
that the front fog lamps are on.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
Instrument lighting
Turn the rotary dial to adjust brightness.
Interior lamps 
The interior lamps operate automatically. 

Climate
62
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
78
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 
and cause an explosion or cause a fire in the 
event of an accident.<
Gas cap
Opening
1.Open the fuel filler door, arrow 1.
2.Turn the gas cap counterclockwise.
3.Place the gas cap in the bracket attached to 
the fuel filler door, arrow 2.
Closing
Fit the gas cap and turn it clockwise until you 
clearly hear a click.
Do not jam the strap between the gas cap 
and the vehicle.<
Warning lamp
* lights up.
The gas cap is not properly closed or is 
missing. Check if the gas cap is prop-
erly closed.
Manually releasing the fuel filler door
In the event of a malfunction, you can release 
the fuel filler door manually:1.Remove the cover for the right-hand rear 
lamps in the cargo bay by turning the lock, 
see arrow.
2.Pull the cargo bay trim panel slightly toward 
the interior. The green button with the fuel 
pump symbol becomes visible.
3.Undo the adhesive strip and pull off.
4.Pull the button. The fuel filler door is 
released.
Pull on the button slowly and care-
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.
