GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

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
Ractivate the "Windshield defrosting" functionbriefly, if required
Climate control regulates the temperature andair humidity in the vehicle interior. The interiorfilter cleans the air, thus improving the interiorclimate.
The "Cooling with air dehumidification" functionis only available when the engine is running.Optimum climate control is only achieved withthe side windows and roof closed.
If you start the engine using your smartphone,the last selected climate control setting is reac-tivated (Ypage 134).
The integrated filter filters out most particles ofdust and soot and completely filters out pollen.It also reduces gaseous pollutants and odors. Aclogged filter reduces the amount of air suppliedto the vehicle interior. For this reason, youshould always observe the interval for replacingthe filter, which is specified in the MaintenanceBooklet. As it depends on environmental condi-tions, e.g. heavy air pollution, the interval maybe shorter than stated in the Maintenance Book-let.
iVentilate the vehicle for a brief period duringwarm weather, e.g. using the convenienceopening feature (Ypage 91). This will speedup the cooling process and the desired inte-rior temperature will be reached morequickly.
iIt is possible that the blower may be activa-ted automatically 60 minutes after the Smart-Key has been removed depending on variousfactors, e.g. the outside temperature. Thevehicle is then ventilated for 30 minutes to drythe automatic climate control.
Control panel for dual-zone automatic climate control
Example: control panel for dual-zone automatic climate control
CSets the temperature, left (Ypage 123)
DSets the air distribution (Ypage 124)

Vehicles with 3-zone automatic climate control:use the "Residual heat" function if you want toheat or ventilate the vehicle interior when theignition is switched off. The residual heat func-tion can only be activated or deactivated withthe ignition switched off. The residual heat func-tion is deactivated when the ignition is switchedon.
DYNAMIC SELECT switch (except
Mercedes-AMG GLC 63 4MATIC/
GLC 63 S 4MATIC)
You can choose between various drive programswith the DYNAMIC SELECT switch(Ypage 139).
If you have selected drive programE:
Rwhen heating, the electrical heater booster isdeactivated and heat output is reduced as aresult
Rthe rear window defroster running time isreduced
If you have selected drive programC,SorS+,the current climate settings are maintained.
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 137).

tems
Activating/deactivating climate con-
trol
General notes
When the climate control is switched off, the airsupply and air circulation are also switched off.The windows could fog up. Therefore, switch offclimate control only briefly
Switch on climate control primarily using theXrocker switch (Ypage 123).
Activating/deactivating
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 131).
XTo switch on:set the airflow to level1orhigher using theHrocker switch.
XTo switch off:set the airflow to level0usingtheHrocker switch.
i3-zone automatic climate control: when cli-mate control is switched off, "OFF" appears inthe rear-compartment display.
Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will notbe cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up morequickly. Therefore, only deactivate the "Cooling with air-dehumidification" function briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. The airinside 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 normaland not a sign that there is a malfunction.
Activating/deactivating
XPress theZrocker switch up or down.The indicator lamp above the rocker switch lights up or goes out.

Problems with the rear window defroster
ProblemPossible causes/consequences andPPSolutions
The rear windowdefroster has deactiva-ted prematurely or can-not be activated.
The battery has not been sufficiently charged.
XSwitch 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 defrostercan be activated again.
Switching air-recirculation mode
on/off
General notes
You can also temporarily deactivate the flow offresh air manually if unpleasant odors are enter-ing the vehicle from outside. The air alreadyinside the vehicle will then be recirculated.
If you switch on air-recirculation mode, the win-dows can fog up more quickly, in particular atlow temperatures. Only use air-recirculationmode briefly to prevent the windows from fog-ging up.
Activating/deactivating
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 131).
XTo activate:press therrocker switch upor down.The indicator lamp above therrockerswitch lights up.
Air-recirculation mode switches on automati-cally:
Rat high outside temperatures
Rat high levels of pollution (3-zone automaticclimate control only)
Rin a tunnel (vehicles with a navigation systemonly)
The indicator lamp above therrockerswitch is not lit when automatic air-recirculationmode is activated. Outside air is added afterabout 30 minutes.
XTo deactivate:press therrocker switchup or down.The indicator lamp above therrockerswitch goes out.
Air-recirculation mode deactivates automati-cally:
Rafter approximately five minutes at outsidetemperatures below approximately 41 ‡(5 †)
Rafter approximately five minutes if coolingwith air dehumidification is deactivated
Rafter approximately 30 minutes at outsidetemperatures above approximately 41 ‡(5 †) if the "Cooling with dehumidification"function is activated
Switching the residual heat on or off
General notes
The residual heat function is only available with3-zone automatic climate control.
Once the engine is switched off, it is possible tomake use of the residual heat of the engine tocontinue heating or ventilating the front com-partment of the vehicle for approximately30 minutes. The heating or ventilation timedepends on the interior temperature that hasbeen set.
Activating/deactivating
XTurn the SmartKey to position

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and drivingsafety systems adjusts automatically while acertain distance is being driven after the vehiclehas been delivered or after repairs. Full systemeffectiveness is not reached until the end of thisteach-in procedure.
New and replaced brake pads and discs onlyreach their optimum braking effect after severalhundred kilometers of driving. Compensate forthis by applying greater force to the brake pedal.
The first 1,000 miles (1,500 km)
The more you look after the engine when it isnew, the more satisfied you will be with its per-formance in the future.
RYou should therefore drive at varying vehicleand engine speeds for the first 1,000 miles(1,500 km).
RAvoid heavy loads, e.g. driving at full throttle,during this period.
RWhen changing gears manually, change up ingood time. Change gear before the tachome-ter needle is
