Heating and cooling

The humidity of the air is automatically reduced when the system

cools the interior of the vehicle. This helps to prevent condensation

on the windows.

– Select the desired air conditioner settings using the

rotary pushbutton ⇒ page 98, fig. 112.

The following functions are available:

If the humidity and temperature outside the vehicle are high,

condensation can drip off the evaporator in the air cooling system

and form a pool underneath the vehicle. This is normal and does not

indicate a leak.

• Running time* ⇒ page 111

• Timer status* ⇒ page 110

• Timer 1* ⇒ page 110

• Timer 2* ⇒ page 110

• Timer 3* ⇒ page 110

If the outside temperature is low, the blower normally only switches

to a higher speed once the coolant has warmed up sufficiently (this

does not apply to the defrost setting).

In order to achieve maximum engine power, the air conditioner

compressor is temporarily switched off when pulling away from a

standstill with full throttle.

The compressor also switches off if the coolant temperature is

excessively high, to ensure adequate engine cooling under extreme

loads.

Pollution filter

Description

The pollution filter (a combined particle filter and activated charcoal

filter) serves as a barrier against impurities in the outside air,

including dust and pollen, and against unpleasant smells. The air is

also filtered when the air recirculation mode is activated.

The air conditioner is designed to keep the passenger

compartment at the temperature you find most comfort-

able at all times of the year.

For the air conditioner to work with maximum efficiency, the pollu-

tion filter element must be replaced at the intervals specified in the

Service Schedule.

The air conditioner provides heating and ventilation and also cools

and dehumidifies the air inside the vehicle.

The air conditioner is fully automatic, and will maintain the desired

temperature at a constant level. To achieve this, the temperature of

the air supplied to the interior, the blower speed (volume of air

delivery) and the air distribution are regulated automatically. The

system also allows for the effect of strong sunlight, so there is no

need for manual adjustment. For these reasons it is advisable to use

the automatic mode for the comfort of all the passengers in virtually

all conditions throughout the year ⇒ page 101.

If the vehicle is driven in areas with a high level of air pollution and

the filter is no longer fully effective, it may be necessary to change

the filter element more frequently.

Key-coded settings

The currently selected air conditioner settings are automatically

stored and assigned to the remote control key.

Heating and cooling

Power management

• The air conditioner operates most effectively with the windows

and the tilting panorama roof* closed. However, if the vehicle has

heated up after standing in the sun for some time, the air inside can

be cooled more quickly by opening the windows for a short time.

To prevent the battery from becoming discharged and to maintain

the necessary power level, the system will temporarily shut off the

electrical components that are using a lot of power, or reduce the

current they are consuming ⇒ page 192. Heating systems in partic-

ular use a large amount of electrical power. If you notice, for

instance, that the rear window heater is not working, it may have

been temporarily switched off by the power management function,

or regulated to a lower heat output. These systems will be available

again as soon as sufficient electrical power is available.

Applies to vehicles: with deluxe automatic air conditioner plus

Controls

WARNING

For safety reasons it is important that all the windows are kept

free of ice, snow and condensation. These can cause poor visibility

and lead to an accident. Please familiarise yourself with the oper-

ating controls for the air conditioner, including the demist/defrost

functions for the windows.

Caution

• If you suspect that the air conditioner is damaged, switch it off

to prevent further damage and have the system checked by a quali-

fied workshop.

• Repairs to the air conditioning system require specialist knowl-

edge and special tools. For this reason, please contact a qualified

workshop if the system is not working properly.

The left-hand display shows the temperature selected for the left-

hand side, the right-hand display the temperature for the right-hand

side.

Note

• Keep the air intake slots in front of the windscreen clear of snow,

ice and leaves to ensure unimpaired heating and cooling, and to

prevent the windows misting over.

The functions can be switched on and off by turning the controls or

briefly pressing the buttons. The LEDs in the buttons light up when

the function is switched on.

• The air from the outlets flows through the passenger compart-

ment and out through the slots at the rear of the vehicle. Do not

cover these slots with clothing or other objects.

this temperature. The system automatically compensates for any

variations in the outside temperature and for the effect of direct

sunlight.

The automatic temperature regulation only operates at temperature

settings between +16 °C and +28 °C. If a temperature below +16 °C

is selected, LO appears on the display. If a temperature above +28 °C

is selected, the display will show HI. In the two extreme settings the

air conditioner operates continuously with maximum cooling or

recirculation mode in the following circumstances:

The air conditioning system automatically regulates the blower

speed according to the interior temperature. However, you can also

adjust the blower speed manually.

heating is switched on, this setting will remain activated for 15

minutes after switching off the ignition.

Air outlets

The air distribution setting directs the air to the outlets

you select.

If the engine is started again during this period of 15 minutes, the

rear window heating will be switched on for about 10 to 20 minutes,

depending on the exterior temperature. This means you do not have

to manually switch on the rear window heating again if the vehicle

has only been parked for a short time.

For the sake of the environment

Switch off the heated rear window manually as soon as the rear

window is clear. By saving electrical power you can also save fuel.

adjusted horizontally and vertically using the adjuster in

the centre of each outlet grille.

Note

If the LED in the AC button should continue to light up when the AC

mode has been switched off (i.e. the air conditioner has been

switched off) this is due to a defect in one of the air conditioner

components. If a malfunction should occur, please contact a quali-

fied workshop.

The flow of air from the outlets is controlled either automatically or

manually, depending on the operating mode selected. Outlets A to

A can provide air which is either heated, unheated, or cooled.

Economical operation of the air conditioner

When the air conditioner is operating in the cooling mode, the air is

directed mainly to outlets A and A. To ensure an adequate cooling

effect, you should not close these outlets completely.

Economical operation of the air conditioner will help to

save fuel.

When the air conditioner is operating in the cooling mode it

reduces engine power and increases fuel consumption. To

ensure that the cooling mode is activated only when really

necessary, please note the following points:

Applies to vehicles: with deluxe automatic air conditioner plus

Air outlets for rear passengers

The air outlets for the rear cabin are located in the centre

console.

– Switch off the cooling mode by pressing the AC button

(LED off) if you wish to save fuel.

– The outlets can be opened and closed by turning the

thumbwheels.

– You should also switch off the cooling mode by pressing

the AC button (LED off) if you open the windows or the

tilting panorama roof* while driving.

– The direction of air delivery from these outlets can be

adjusted horizontally and vertically using the adjuster in

the centre of each outlet grille.

– If the vehicle has heated up after standing in the sun,

open the windows and doors for a short time to cool the

vehicle.

The flow of air from the outlets is controlled either automatically or

manually, depending on the operating mode selected. All the

outlets can provide air which is either heated, unheated, or cooled.

For the sake of the environment

By saving fuel you also reduce the amount of pollutants emitted

from your vehicle.

The heater outlets for the rear footwells are located under the front

seats.

Note

When the air conditioner is operating in the cooling mode the air is

directed mainly to the outlets in the centre console. To ensure an

adequate cooling effect, you should not close these outlets

completely.
