centration of fine particulate matter and pollen

and neutralises odours in the vehicle interior.

Heating and cooling

Air conditioner

Introduction

Depending on your vehicle’s equipment, one of

the following options is available:

Information on the air conditioner for the

European Union

– A two-zone deluxe automatic air conditioner

which can be used to individually adjust the

temperature and air distribution at the front

left and right. The air output can be set central-

ly for the entire vehicle using the controls for

the front seats.

The air conditioner contains the fluorinated

greenhouse gas known as R-1234yf.

Further information on the quantity of this

greenhouse gas, the CO equivalent and the

2

global warming potential (GWP) is provided on a

sticker in the engine compartment.

– A four-zone deluxe automatic air conditioner

which can be used to individually adjust the

temperature, air distribution and blower speed

settings for all the seats.

Overview of air conditioner displays

The air conditioner heats, cools, dehumidifies

and filters the air inside the vehicle. It operates

most effectively with the windows and the sun-

roof (if fitted) closed. If the vehicle has been

standing in the sun, it may cool down faster if

you open the windows briefly to let the hot air es-

cape.

Fig. 68 Centre display: Deluxe air conditioner control bar

The deluxe automatic air conditioner will main-

tain the desired temperature at a constant level.

When the heater is on, the blower normally only

switches to a higher setting once the heater has

warmed up sufficiently (this does not apply to

the defrost setting).

All of the air conditioner settings are available on

the centre display; for the rear seats, only certain

functions are available.

Adjusting the air conditioner control bar

You can replace certain air conditioner functions

in the lower control bar 1 with an air conditioner

function from the air conditioner menu.
