Starting the engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral or move the
selector lever to position P and forcefully apply
the parking brake to prevent the car from mov-
ing.<
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter.<

The automatic climate control goes into recir-
culated-air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open
them for maximum cooling.
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 influences as a result
of seasonal changes, e.g. sunlight or window
condensation.
The cooling is switched on automatically with
the AUTO program.
Convertible program
The Convertible program is active when the
convertible top is open. In the Convertible pro-
gram, the automatic climate control is opti-
mized for driving with the convertible top down.
In addition, the air flow rate is increased as vehi-
cle speed increases.
The effectiveness of the Convertible pro-
gram can be enhanced considerably by
installing the wind deflector.<
Adjusting air flow rate manually
Press the left side of the button to
reduce airflow. Press the right side
of the button to increase it. You can
reactivate the automatic mode for the air flow
rate with the AUTO button.
The air flow rate may be reduced or the blower
may be switched off entirely to save on battery
power. The display remains the same.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic climate control. All displays are cleared
except for the rear window defroster if it is
switched on.
Press any button except REST or rear window defroster to reactivate the automatic climate
control.
The recirculated-air mode is switched on
when you switch off the automatic cli-
mate control. If the air quality deteriorates or the
window fogs over, switch the system back on
and increase the air volume.<
Automatic recirculated-air control
AUC/Recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
>LED off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. The system then recirculates the
air currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air flow rate as
required.
The recirculated-air mode should not be used
continuously for lengthy periods, otherwise the
quality of the air inside the car will gradually
deteriorate.<
Via the button* on the steering wheel
You can use a button on the steering wheel,
refer to page11, to select between the different
modes.
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
