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

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).

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.

Setting climate control to automatic

General notes

The automatic function is only available in

conjunction with dual-zone automatic climate

control.

In automatic mode, the set temperature is

maintained automatically at a constant level.

The system automatically regulates the tem-

perature of the dispensed air, the airflow and

the air distribution.

The automatic mode functions optimally

when the "Cooling with air dehumidification"

function is activated. If necessary, cooling

with air dehumidification can be deactivated.

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 rear window defroster switches off auto-

matically after several minutes.

dow defroster may switch off.

Problems with the rear window defroster

Problem

Possible causes/consequences and MM Solutions

The rear window

defroster has deactiva-

ted prematurely or can-

not be activated.

The battery has not been sufficiently charged.

Switch off any consumers that are not required, e.g. reading

lamps, interior lighting or the seat heating.

When the battery is sufficiently charged, the rear window

defroster can be activated again.

Activating/deactivating air-recircula-

tion mode

General notes

You can deactivate the flow of fresh air if

unpleasant odors are entering the vehicle

from outside. The air already inside the vehi-

cle will then be recirculated.

If you switch on air-recirculation mode, the

windows can fog up more quickly, in particu-

lar at low temperatures. Only use air-recircu-

lation mode briefly to prevent the windows

from fogging up.

The operation of air-recirculation mode is the

same for all control panels.

Activating/deactivating

Turn the SmartKey to position 2 in the igni-

tion lock (Y page 143).

To activate: press the e button.

The indicator lamp in the e button lights

up.

Air-recirculation mode is activated auto-

matically at high outside temperatures.

When air-recirculation mode is activated

automatically, the indicator lamp in the

e button is not lit. Outside air is added

after about 30 minutes.

To deactivate: press the e button.

The indicator lamp in the e button goes

out.

i Air-recirculation mode deactivates auto-

matically:

after approximately five minutes at out-

side temperatures below approximately

41 ‡ (5 †)

after approximately five minutes if the

"Cooling with air dehumidification" func-

tion is deactivated

after approximately 30 minutes at out-

side temperatures above approximately

41 ‡ (5 †) if the "Cooling with air dehu-

midification" function is activated

Activating/deactivating the residual

heat function

General notes

The residual heat function is only available in

vehicles for Canada with dual-zone automatic

climate control.

It is possible to make use of the residual heat

of the engine to continue heating the vehicle

for approximately 30 minutes after the engine

has been switched off. The heating time

depends on the set interior temperature.

The blower will run at a low speed regard-

less of the airflow setting.

If you activate the residual heat function

at high temperatures, only the ventilation

will be activated. The blower runs at

medium speed.

You cannot use the ventilation to cool the

vehicle interior to a temperature lower than

the outside temperature.

Activating/deactivating

if the battery voltage drops

Setting the air vents

Important safety notes

WARNING

Very hot or very cold air can flow from the air

vents. This could result in burns or frostbite in

the immediate vicinity of the air vents. There

is a risk of injury.

Make sure that all vehicle occupants always

maintain a sufficient distance to the air out-

lets. If necessary, redirect the airflow to

another area of the vehicle interior.

In order to ensure the direct flow of fresh air

through the air vents into the vehicle interior,

please observe the following notes:

keep the air inlet between the windshield

and the hood free of blockages, such as ice,

snow or leaves.

never cover the air vents or air intake grilles

in the vehicle interior.

You can move the adjusters for the air

vents vertically or horizontally to set the

direction of the airflow.

For optimal climate control in the vehicle,

open the air vents completely and set the

adjusters to the central position.

Setting the center air vents

To open the center air vent: turn the

adjuster in one of center air vents : coun-

ter-clockwise to position 2.

To close the center air vent: turn the

adjuster in one of center air vents : clock-

wise as far as it will go to position 3.
