Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwisefog up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-tion function
Rswitch on the defrost windshield functionbriefly, if required
Climate control regulates the temperature andthe humidity in the vehicle interior and filtersundesirable substances out of the air.
Climate control can only be operated when theengine is running. Optimum operation is only
achieved with the side windows and roofclosed.
iWhen the weather is warm, ventilate thevehicle for a brief period. This will speed upthe cooling process and the desired vehicleinterior temperature will be reached morequickly.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollu-tants and odors. A clogged filter reduces theamount of air supplied to the vehicle inte-rior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the Maintenance Book-let. As it depends on environmental condi-tions, e.g. heavy air pollution, the intervalmay be shorter than stated in the Mainte-nance Booklet.

Setting climate control to automatic
General notes
Automatic mode is only available with 3-zoneautomatic climate control.
In automatic mode, the set temperature ismaintained automatically at a constant level.The system automatically regulates the tem-perature of the dispensed air, the airflow andthe air distribution.
The automatic mode functions optimally whenthe "Cooling with air dehumidification" func-tion is activated. If necessary, cooling with airdehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-midification" function, the air inside the vehiclewill not be cooled. The air inside the vehiclewill also not be dehumidified. The windows canfog up more quickly. Therefore, deactivate thecooling with air-dehumidification function onlybriefly.

a risk of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in

During a cold start, the engine runs at higherspeeds to enable the catalytic converter toreach its operating temperature. The sound ofthe engine may change during this time.
Automatic transmission

Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position:
orF, the vehicle could pull away sud-
denly. There is a risk of an accident.
When engaging transmission position:
orF, always firmly depress the brake
pedal and do not simultaneously accelerate.
!Change gear in good time and avoid spin-ning the wheels. You could otherwise dam-age the vehicle.
Depress the accelerator carefully when pullingaway.
The vehicle locks centrally once you havepulled away. The locking knobs in the doorsdrop down.
You can open the doors from the inside at anytime.
You can also deactivate the automatic lockingfeature (Ypage 178).
It is only possible to shift the transmissionfrom position]to the desired position if youdepress the brake pedal. Only then is the shiftlock released.
iUpshifts take place at higher enginespeeds after a cold start. This helps the cat-alytic converter to reach its operating tem-perature more quickly.
Information on the automatic release of theelectric parking brake (Ypage 136).
Hill start assist
Hill start assist helps you when pulling awayforward or in reverse on an uphill gradient. Itholds the vehicle for a short time after youhave removed your foot from the brake pedal.This gives you enough time to move your footfrom the brake pedal to the accelerator pedaland to depress it before the vehicle begins toroll.
