daytime running lamps or low-beam head-lamps go out after 3 minutes.
When the engine is running, the vehicle is sta-tionary and in bright ambient light: if you turnthe light switch to the`position, the day-time running lamps and parking lamps turn on.
If the engine is running and you turn the lightswitch to theXposition, the manual set-tings take precedence over the daytime run-ning lamps.
USA only:
The daytime running lamps improve the visibil-ity of your vehicle during the day. To do this,the daytime running lamps function must beswitched on using the on-board computer(Ypage 199).
If the engine is running and you turn the lightswitch to the`orXposition, the man-ual settings take precedence over the daytimerunning lamps.
Low-beam headlamps

Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwisefog up.
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 tempera-ture and the humidity of the vehicle interiorand filters undesirable substances from theair.
The air-conditioning system or dual-zone auto-matic climate control can only be operatedwhen the engine is running. Optimum opera-tion is only achieved with the side windowsand panorama roof with power tilt/slidingpanel closed.
If you start the engine using your smartphone,the last selected climate control setting isreactivated (Ypage 84).
The residual heat function can only be activa-ted or deactivated with the ignition switchedoff (Ypage 122).
Always keep the ventilation flaps behind theside trim panel in the cargo compartmentclear (Ypage 108). Otherwise the vehicle willnot be ventilated correctly.
iVentilate the vehicle for a brief period dur-ing warm weather, e.g. using the conveni-ence opening feature (Ypage 84). This willspeed up the cooling process and thedesired interior temperature will be reachedmore quickly.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollu-tants and odors. A clogged filter reduces theamount of air supplied to the vehicle inte-rior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the Maintenance Book-let. As it depends on environmental condi-tions, e.g. heavy air pollution, the intervalmay be shorter than stated in the Mainte-nance Booklet.
iIt is possible that under certain circum-stances the residual heat function may beactivated automatically an hour after theSmartKey has been removed in order to drythe automatic climate control. The vehicle isthen ventilated for 30 minutes.
Overview of climate control systems113
Climate control

It is possible to make use of the residual heatof the engine to continue heating the vehiclefor approximately 30 minutes after the enginehas been switched off. The heating timedepends on the set interior temperature.
iThe blower will run at a low speed regard-less of the airflow setting.
iIf you activate the residual heat function athigh temperatures, only the ventilation willbe activated. The blower runs at mediumspeed.
iYou cannot use the ventilation to cool thevehicle interior to a temperature lower thanthe outside temperature.
Activating/deactivating
XTurn the SmartKey to positionZin the igni-tion lock or remove it (Ypage 125).
XPress theKbutton.The indicator lamp in theKbutton lightsup or goes out.
The indicator lamp in the button indicatesthat the respective function is activated.
iResidual heat is deactivated automatically:
Rafter approximately 30 minutes
Rwhen the ignition is switched on
Rif the battery voltage drops
Air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the
air vents. This could result in burns or frost-
bite 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 airthrough the air vents into the vehicle interior,please observe the following notes:
Rkeep the air inlet between the windshieldand the hood free of blockages, such as ice,snow or leaves.
Rnever cover the air vents or air intake grillesin the vehicle interior.
iFor optimal climate control in the vehicle,open the air vents completely and set theadjusters to the central position.

There is a risk of fire and an accident.
Release the parking brake fully before driv-
ing off.
!Do not warm up the engine while station-ary. Pull away immediately. Avoid highengine speeds and full throttle until theengine has reached its operating tempera-ture.
In vehicles with automatic transmission,engage positions P and R only when thevehicle is stationary.
Where possible, avoid spinning the drivewheels when pulling away on slippery roads.You could otherwise damage the drive train.
!Mercedes-AMG vehicles:avoid full-loadoperation and engine speeds greater than5000 rpm when the engine is cold. Thishelps to protect the engine and avoidsuncomfortable driving.

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped withSmartKeys featuring the integrated KEYLESS-GO function and a detachable Start/Stop but-ton.
A check which periodically establishes a radioconnection between the vehicle and theSmartKey determines whether a valid Smart-Key is in the vehicle. This occurs, for example,when starting the engine.
When you insert the Start/Stop button intothe ignition lock, the system needs approx-imately two seconds recognition time. You canthen use the Start/Stop button.
Pressing the Start/Stop button several timesin succession corresponds to the differentSmartKey positions in the ignition lock. This isonly the case if you are not depressing thebrake pedal.
If you depress the brake pedal and press theStart/Stop button, the engine starts immedi-ately.
To start the vehicle without actively using theSmartKey:
Rthe Start/Stop button must be inserted inthe ignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with theSmartKey or KEYLESS-GO (Ypage 70)
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile phoneor another SmartKey.
Rwith metallic objects, e.g. coins or metalfoil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKeyremote control or with KEYLESS-GO, after ashort time:
Ryou will not be able to switch on the ignitionwith the Start/Stop button.
Ryou will no longer be able to start the enginewith the Start/Stop button until the vehicleis unlocked again.
If you lock the vehicle centrally using the but-ton on the front door (Ypage 75), you cancontinue to start the engine with the Start/Stop button.
