2019 MERCEDES-BENZ CLA climate settings

Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwise fogup.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-tion function
Rswitch on the defrost windshield functionbriefly, if required
The air-conditioning system or dual-zone auto-matic climate control regulates the temperatureand the humidity of the vehicle interior and fil-ters undesirable substances from the air.
The air-conditioning system or dual-zone auto-matic climate control can only be operatedwhen the engine is running. Optimum operationis only achieved with the side windows and pan-orama roof with power tilt/sliding panel closed.
If you start the engine using your smartphone,the last selected climate control setting is reac-tivated (Ypage 83).
The residual heat function can only be activatedor deactivated with the ignition switched off(Ypage 120).
Always keep the ventilation flaps behind theside trim panel in the cargo compartment clear(Ypage 107). Otherwise the vehicle will not beventilated correctly.
iVentilate the vehicle for a brief period duringwarm weather, e.g. using the convenienceopening feature (Ypage 83). This will speedup the cooling process and the desired inte-rior temperature will be reached morequickly.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollutantsand odors. A clogged filter reduces theamount of air supplied to the vehicle interior.For this reason, you should always observethe interval for replacing the filter, which isspecified in the Maintenance Booklet. As itdepends on environmental conditions, e.g.heavy air pollution, the interval may beshorter than stated in the Maintenance Book-let.
iIt is possible that under certain circumstan-ces the residual heat function may be activa-ted automatically an hour after the SmartKeyhas been removed in order to dry the auto-matic climate control. The vehicle is then ven-tilated for 30 minutes.

ual. You will see the current settings of thevarious climate control functions.
DYNAMIC SELECT button (except
Mercedes-AMG vehicles)
You can choose between various drive programswith the DYNAMIC SELECT button(Ypage 129).
If you have selected drive programE:
Rwhen heating, the electrical heater booster isdeactivated and in the warming-up phaseheat output is reduced
Rthe rear window defroster running time isreduced
Depending on the configuration, climate set-tings may also be influenced in the drive pro-gramI.
If you have selected drive programCorS, cli-mate settings are not influenced.
ECO start/stop function
During automatic engine switch-off, the climatecontrol system only operates at a reduced capa-city. If you require the full climate control output,you can switch off the ECO start/stop functionby pressing the ECO button (Ypage 128).

Drive program I (Individual)
In drive programIthe following properties of thedrive program can be selected:
Rthe drive (engine and transmission manage-ment)
Rthe suspension (vehicles with damping sys-tem or AMG adaptive sport suspension sys-tem)
Rthe steering
Rthe availability of the ECO start/stop function
Rthe climate control
Information about configuring drive programIwith the multimedia system can be found in theDigital Operator's Manual.
iTo permanently select the gears in driveprogramIusing the steering wheel paddleshifters, select theM(manual) setting for thedrive.
Drive program E (Economy)
Drive programEis characterized by the follow-ing:
Rcomfort-oriented engine settings.
Roptimal fuel consumption resulting from theautomatic transmission shifting up sooner.
Rthe vehicle pulls away more gently in forwardand reverse gears, unless the acceleratorpedal is depressed fully.
Rthe vehicle has improved driving stability, forexample on slippery road surfaces.
Rthe automatic transmission shifting upsooner. This results in the vehicle being drivenat lower engine speeds and the wheels beingless likely to spin.
Rgliding mode is activated automatically whenengine-internal conditions are fulfilled andthe accelerator is not depressed. At the sametime the transmission’s clutch opens and thevehicle rolls freely using its kinetic energy. Asa result great distances can be completedwithout the engine brake and fuel consump-tion reduced.
iThe availability of gliding mode depends onvarious factors, including the following:
Rthe engine and transmission temperature
Rthe downhill gradient
Rthe vehicle speed
Rperforming regular adaptation functions
When you depress the brake pedal, glidingmode is deactivated, depending on pedalpressure.
When you activate cruise control or ActiveDistance Assist DISTRONIC, gliding mode isnot available.

Drive program S (Sport)
Drive programSis characterized by the follow-ing:
Rthe vehicle exhibits sporty driving character-istics.
Rthe automatic transmission shifts up later.The fuel consumption possibly being higheras a result of the later automatic transmissionshift points.
Rthe suspension exhibits stiff springing anddamping settings (vehicles with AIR adaptivesport suspension system).

Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle when driving, you may be distracted from
the traffic situation. You could also lose con-
trol of the vehicle. There is a risk of an acci-
dent.
Only operate this equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for thecountry in which you are currently driving whenoperating the navigation system.
General notes
Among other things, correct functioning of thenavigation system depends on GPS reception. Incertain situations, GPS reception may beimpaired, there may be interference or theremay be no reception at all, e.g. in tunnels orparking garages.
Audio 20 is equipped with Garmin®MAP PILOT(see the manufacturer's operating instructions).
The Garmin®MAP PILOT operating instructionsare stored on the SD card as a PDF file. The SDcard box contains a quick guide.
