Controls in detail

Climate control

The climate control is operational when-

ever the engine is running. You can oper-

ate the climate control system in either the

automatic or manual mode. The system

cools or heats the interior depending on

the selected interior temperature and the

current outside temperature.

Nearly all dust particles, pollutants and

odors are filtered out before outside air en-

ters the passenger compartment through

the air distribution system.

The air conditioning will not engage (no

cooling) if the mode AC

OFF

is selected

(컄 page 181).

Warning! G

When operating the climate control, the air

that enters the passenger compartment

through the air vents in the footwell can be

very hot or very cold (depending on the set

temperature). This may cause burns or frost-

bite on unprotected skin in the immediate

area of the air vents. Always keep sufficient

distance between unprotected parts of the

body and the footwell air vents. If necessary,

change the air flow using the air distribution

controls to direct the air away from the foot-

well air vents (

컄 page 178).

Warning! G

Follow the recommended settings for heat-

ing and cooling given on the following pag-

es. Otherwise the windows could fog up,

impairing visibility and endangering you and

others.

Severe conditions (e.g. strong air

pollution) may require replacement of

the filter before its scheduled interval.

A clogged filter will reduce the air

volume to the interior.

If the vehicle interior is hot, ventilate

the interior before driving off, see

“Opening (Summer opening feature)”

(

컄 page 229).

Keep the air intake grille in front of the

windshield free of snow and debris.

Do not obstruct air flow by placing

objects on the air flow-through exhaust

slots below the rear window.

Deactivating the climate control

system

Deactivating

왘 Set air volume control 1 (컄 page 175)

to position 0.

Reactivating

왘 Set air volume control 1 (컄 page 175)

to any speed.

Setting the temperature

Use temperature controls 2 and 3

(컄 page 175) to separately adjust the air

temperature on each side of the passenger

compartment. You should raise or lower

the temperature setting in small incre-

ments, preferably starting at 72°F (22°C).

Increasing

왘 Turn temperature control 2 or 3

slightly to the right.

The climate control system will corre-

spondingly adjust the interior air tem-

perature.

Decreasing

왘 Turn temperature control 2 or 3

slightly to the left.

The climate control system will corre-

spondingly adjust the interior air tem-

perature.

When the air conditioning is switched

off, the outside air supply and circula-

tion are also switched off. Only choose

this setting for a short time. Otherwise

the windows could fog up.

When operating the climate control

system in automatic mode, you will

only rarely need to adjust the tempera-

ture, air volume and air distribution.

Adjusting air distribution and volume

Use air distribution control 4

(컄 page 175) to adjust the air distribution.

The following symbols are found on the

controls:

Use the air volume control 1

(컄 page 175) to adjust the air volume. You

The indicator lamp on the button goes

out.

왘 Select any of the six air volume speeds

and the air distribution.

왘 Press button U (컄 page 175).

The indicator lamp on the button

comes on. The temperature, air distri-

bution and volume are adjusted auto-

matically.

Windshield fogged on the outside

왘 Switch the windshield wipers on

(컄 page 51).

왘 Switch to manual mode.

왘 Turn the air distribution control

to a or Y.

Defrosting

Activating

왘 Press button P (컄 page 175).

The indicator lamp on the button

comes on.

The air conditioning switches

automatically to the following functions:

Symbol Function

Z Directs air to the windshield

and the side defroster vents

b Directs air into the entire

vehicle interior

Y Directs air to the footwells

a Directs air through the center,

side and rear passenger

compartment air vents

These settings should only be selected

for a short time.

Climate control

Deactivating

왘 Press button P (컄 page 175).

The indicator lamp on the button goes

out. Defrosting is turned off.

Air recirculation mode

Switch to air recirculation mode to prevent

unpleasant odors from entering the vehicle

from the outside. This setting cuts off the

intake of outside air and recirculates the

air in the passenger compartment.

Activating

왘 Press button , (컄 page 175).

The indicator lamp on the button

comes on.

Warning! G

When the outside temperature is

below 41°F (5°C), only switch to air

recirculation mode for short periods to

prevent window fogging.

Window fogging may impair visibility and

endanger you and others.

If you keep button , pressed the

side windows and tilt/sliding sunroof*

will close.

Warning! G

Never operate the side windows and the

tilt/sliding sunroof* if there is the possibility

of anyone being harmed by the closing pro-

cedure.

In the event that the closing procedure

causes potential danger, the closing of the

side windows can be immediately halted by

pressing or pulling the respective window

switch. The closing of the tilt/sliding

sunroof* can be immediately halted by

moving the tilt/sliding sunroof* switch in

the overhead control panel in any direction.

Deactivating

왘 Press button , (컄 page 175).

The indicator lamp on the button goes

out.

The air recirculation mode is deactivated

automatically:

앫 after five minutes if the outside

temperature is below

approximately 41°F (5°C)

앫 after five minutes if the air conditioning

is turned off

앫 after 30 minutes if the outside

temperature is above

approximately 41°F (5°C)

At outside temperatures above 79°F

(26°C) the system will not automatically

switch back to outside air. A quantity of

outside air is added after approximately

30 minutes.

The air recirculation mode is activated

automatically at high outside tempera-

tures.

The indicator lamp on the , button

is not lit when the air recirculation

mode is automatically switched on.

After approx. 30 minutes, outside air is

added to the air inside the vehicle.

If you have turned off the air condi-

tioning (

컄 page 181) or the outside

temperature is below 41°F (5°C), the

air recirculation mode will not switch

on automatically.

If you keep button , pressed the

side windows and tilt/sliding sunroof*

will return to their previous position.

Air conditioning

The air conditioning is operational while

the engine is running and cools the interior

air to the temperature set by the operator.

Deactivating

It is possible to deactivate the air condi-

tioning (cooling) function of the climate

control system. The air in the vehicle will

then no longer be cooled or dehumidified.

왘 Press button ± (컄 page 175).

The indicator lamp on the button

comes on.

The cooling function switches off after

a short delay.

Activating

Moist air can fog up the windows. You can

dehumidify the air with the air condition-

ing.

왘 Press button ± (컄 page 175).

The indicator lamp on the button goes

out.

The air conditioning uses the

refrigerant R134a. This refrigerant is free

of CFCs which are harmful to the ozone

layer.

Condensation may drip out from under-

neath the vehicle. This is normal and

not an indication of a malfunction.

Warning! G

If you turn off the cooling function, the

vehicle will not be cooled when weather

conditions are warm. The windows can fog

up more quickly. Window fogging may

impair visibility and endanger you and

others.

If the air conditioning cannot be turned

on again, this indicates that the air

conditioning is losing refrigerant. The

compressor has turned itself off.

Have the air conditioning checked at

the nearest authorized Mercedes-Benz

Center.
