Get Climate control -> Overview of climate control systems Guide for Mercedes GLA SUV First Generation (2013-2019)

Useful information

This Operator's Manual describes all

models and all standard and optional equip-

ment of your vehicle available at the time of

publication of the Operator's Manual.

Country-specific differences are possible.

Please note that your vehicle may not be

equipped with all features described. This

also applies to safety-related systems and

functions.

Read the information on qualified special-

ist workshops (Y page 28).

Overview of climate control systems

General notes

Observe the settings recommended on the

following pages. The windows could other-

wise fog up.

To prevent the windows from fogging up:

switch off climate control only briefly

switch on air-recirculation mode only

briefly

switch on the cooling with air dehumidifi-

cation function

switch on the defrost windshield function

briefly, if required

The air-conditioning system/dual-zone auto-

matic climate control regulates the tempera-

ture and the humidity of the vehicle interior

and filters out undesirable substances from

the air.

The air-conditioning system/dual-zone auto-

matic climate control can only be operated

when the engine is running. Optimum opera-

tion is only achieved with the side windows

and panorama roof with power tilt/sliding

panel closed.

The residual heat function can only be acti-

vated or deactivated with the ignition

switched off (Y page 137).

Always keep the ventilation flaps behind the

side trim panel in the cargo compartment

clear (Y page 119). Otherwise the vehicle will

not be ventilated correctly.

Ventilate the vehicle for a brief period

during warm weather, e.g. using the con-

venience opening feature (Y page 88). This

will speed up the cooling process and the

desired interior temperature will be

reached more quickly.

The integrated filter filters out most par-

ticles of dust and soot and completely fil-

ters out pollen. It also reduces gaseous pol-

lutants and odors. A clogged filter reduces

the amount of air supplied to the vehicle

interior. For this reason, you should always

observe the interval for replacing the filter,

which is specified in the Maintenance

Booklet. As it depends on environmental

conditions, e.g. heavy air pollution, the

interval may be shorter than stated in the

Maintenance Booklet.

It is possible that the residual heat func-

tion may be activated automatically an hour

after the SmartKey has been removed in

order to dry the air-conditioning system.

The vehicle is then ventilated for

30 minutes.

Notes on using the air-conditioning

system

Air-conditioning system

Below, you can find a number of notes and

recommendations to help you use the air-

conditioning system optimally.

Switch on the air-conditioning system by

turning control knob A clockwise to the

desired position (except position 0).

Set the temperature to 72 ‡ (22 †).

Recommendation for avoiding misted

windows at low exterior temperatures

or in rain: switch on the ¿ cooling with

dehumidification function (Y page 131).

Set air distribution to ¯ and if possible

switch off P and O (Y page 134).

In air-recirculation mode, switch e off

(Y page 137).

Set airflow control A to a setting between

3 and 6 (Y page 134).

Recommendation for rapid cooling or

heating of the vehicle interior: briefly set

airflow control A to a setting between 3

and 6 (Y page 134).

Recommendation for a constant vehi-

cle interior temperature: set airflow con-

trol A to a setting between 1 and 3

(Y page 134).

Recommendation for air distribution in

the winter: set O and ¯

(Y page 134).

Recommendation for air distribution in

the summer: set P or P and ¯

(Y page 134).

Only use the "Windshield defrosting" func-

tion briefly until the windshield is clear

again.

Only use air-recirculation mode briefly, e.g.

if there are unpleasant outside odors or

when in a tunnel. The windows could oth-

erwise fog up, since no fresh air is drawn

into the vehicle in air-recirculation mode.

Vehicles with COMAND: if you change the

settings of the climate control system, the

climate status display appears for three

seconds at the bottom of the screen in the

COMAND display. See also the separate

COMAND operating instructions. You will

see the current settings of the various cli-

mate control functions.

ECO start/stop function

During automatic engine switch-off, the cli-

mate control system only operates at a

reduced capacity. If you require the full cli-

mate control output, you can switch off the

ECO start/stop function by pressing the ECO

button (Y page 146).

Optimum use of dual-zone automatic

climate control

Automatic climate control

The following contains instructions and rec-

ommendations to enable you to get the most

out of your dual-zone automatic climate con-

trol.

Activate climate control using the Ã and

¿ buttons. The indicator lamps in the

Ã and ¿ buttons light up.

Set the temperature to 72 ‡ (22 †).

Only use the "Windshield defrosting" func-

tion briefly until the windshield is clear

again.

Only use air-recirculation mode briefly, e.g.

if there are unpleasant outside odors or

when in a tunnel. The windows could oth-

erwise fog up, since no fresh air is drawn

into the vehicle in air-recirculation mode.

Use the ZONE function to adopt the tem-

perature settings on the driver's side for

the front-passenger side as well. The indi-

cator lamp in the á button goes out.

Overview of climate control systems

Climate control

Only available on vehicles for Canada:

use the residual heat function if you want to

heat or ventilate the vehicle interior when

the ignition is switched off. The residual

heat function can only be activated or deac-

tivated with the ignition switched off.

Vehicles with COMAND: if you change the

settings of the climate control system, the

climate status display appears for three

seconds at the bottom of the screen in the

COMAND display. See also the separate

COMAND operating instructions. You will

see the current settings of the various cli-

mate control functions.

ECO start/stop function

During automatic engine switch-off, the cli-

mate control system only operates at a

reduced capacity. If you require the full cli-

mate control output, you can switch off the

ECO start/stop function by pressing the ECO

button (Y page 146).

Operating the climate control sys-

tems

Switching climate control on/off

General notes

When the climate control is switched off, the

air supply and air circulation are also

switched off. The windows could fog up.

Therefore, switch off climate control only

briefly

Air-conditioning system

Turn the SmartKey to position 2 in the igni-

tion lock (Y page 143).

To switch on: turn control A clockwise to

the desired position (except position 0)

(Y page 127).

To switch off: turn control A counter-

clockwise to position 0 (Y page 127).

Dual-zone automatic climate control

Turn the SmartKey to position 2 in the igni-

tion lock (Y page 143).

To activate: press the Ã button.

The indicator lamp in the Ã button lights

up. Airflow and air distribution are set to

automatic mode.

Press the ^ button.

The indicator lamp in the ^ button goes

out. The previously selected settings are

restored.

To deactivate: press the ^ button.

The indicator lamp in the ^ button lights

up.

Dual-zone automatic climate control:

switch on climate control primarily using

the Ã button.

Activating/deactivating cooling with

air dehumidification

General notes

If you deactivate the "Cooling with air-dehu-

midification" function, the air inside the vehi-

cle will not be cooled. The air inside the vehi-

cle will also not be dehumidified. The win-

dows can fog up more quickly. Therefore, only

deactivate the "Cooling with air-dehumidifi-

cation" function briefly.

The "Cooling with air dehumidification" func-

tion is only available when the engine is run-

ning. The air inside the vehicle is cooled and

dehumidified according to the temperature

selected.

Condensation may drip from the underside of

the vehicle when it is in cooling mode. This is

normal and not a sign that there is a malfunc-

tion.
