Light functions
Side lights
If the light switch is in position both headlights light up with side lights together with parts of
the tail light clusters, number plate lighting and the buttons in the centre console and the dash
panel. The daytime running lights also switch on when the ignition is switched on.
If the vehicle is not locked from outside (when the ignition is switched off) the continuous parking
light on both sides of the vehicle switches on automatically after ten minutes to reduce 12-volt
vehicle battery discharge ⇒ Switching the parking lights on and off.
Automatic headlights
When the light switch is in position , the vehicle lighting and the instrument and switch
lighting will switch on and off automatically depending on the light conditions. When the lights are
switched on, the indicator lamp in the light switch lights up yellow.
The automatic headlight control function is merely an aid and will not always be able to detect all
driving situations.
In vehicles with a corresponding equipment level, the switch-on time for automatic headlight control
can be adjusted in the Infotainment system in the Vehicle settings menu ⇒ Operation and
display in the Infotainment system.
Cornering light
When cornering slowly or travelling around very tight bends, a static cornering light is switched on
automatically.
Accidents and serious injuries can occur if roads are not sufficiently illuminated and other
road users have difficulty seeing the vehicle, or cannot see it at all.
•The light assist functions are designed to provide assistance only. The driver is
responsible for making sure that the vehicle lights are switched on correctly.
•Always switch the dipped beam headlights on if it is dark, raining or visibility is poor.
WARNING
The side lights or daytime running lights are not bright enough to illuminate the road
ahead and to ensure that other road users are able to see you.
•Always switch the dipped beam headlights on if it is dark, raining or visibility is poor.
•The rear lights will not be switched on with the daytime running lights. If the rear lights
are not switched on, the vehicle may not be visible to other road users if it is dark,
raining, or if visibility is poor.
WARNING
The automatic headlights function ( ) switches the dipped beam headlights on and
off only when there is a change to the level of brightness.
•Switch on the dipped beam headlights manually if this is necessary due to particular
weather conditions, e.g. fog.
WARNING

Dynamic cornering light (AFS)
Swivelling lamps automatically improve the lighting of the road when cornering, and even when you
are not driving round a corner. The dynamic cornering light only works at speeds above
approximately 10 km/h (6 mph) and when the dipped beam headlights are switched on.
In vehicles with a corresponding equipment level, the dynamic cornering light can be activated and
deactivated in the Infotainment system in the Vehicle settings menu ⇒ Operation and
display in the Infotainment system:
Signal tones if lights are not switched off
If the key is removed from the ignition lock and the driver door is opened, a signal tone will sound in
the following situations:
•If the parking light is switched on.
•The light switch is in position or .
When the Coming Home function is switched on, no signal tone will be given as a reminder that a
light is still switched on when leaving the vehicle.
Some settings can be stored in the user accounts of the personalisation function and

for as long as the lever is pulled.
When the main beam or headlight flasher are switched on, the blue indicator lamp in the
instrument cluster lights up.
Main-beam control
Depending on the vehicle equipment level, advanced main-beam control may also be available
⇒ Main-beam control.
Main-beam control
The main-beam control automatically dips the headlights when oncoming vehicles and/or vehicles
driving in front are detected. Main-beam control normally also recognises illuminated areas such as
towns and deactivates main beam while driving through them.
Within the limits of the system, main-beam control automatically switches the main beam on at
speeds of over approximately 60 km/h (37 mph), depending on ambient and traffic conditions, and
switches it off again at speeds under approximately 30 km/h (18 mph) ⇒.
There are two versions of the main-beam control system:
•Main-beam control (Light Assist). Main-beam control automatically switches main beam on and
off when other road users are detected.
•Advanced main-beam control (Dynamic Light Assist) ⇒ Advanced main-beam control (Dynamic
Light Assist).
Incorrect use of the main beam headlights can lead to accidents and serious injuries as
the main beam headlights can distract and dazzle other road users.
WARNING

light on both sides of the vehicle is switched on:
•With the ignition on, turn the light switch to the position .
•Switch off the ignition.
•Lock the vehicle from outside.
Automatic switch-off for side lights and parking lights
The side lights and parking lights drain the 12-volt vehicle battery when switched on. In order to
ensure that the engine can be started, the side lights and parking lights are automatically switched
off when the charge level of the 12 V vehicle battery is so low that there is a risk of no longer being
able to restart the vehicle. Switch-off takes place at the earliest after the side and parking lights
have been switched on for two hours.
The side lights and parking lights will not switch off automatically if there is insufficient battery
capacity for them to remain switched on for two hours. In this case, the side lights and parking lights
will remain switched on until the 12-volt vehicle battery is fully discharged. It will no longer be
possible to restart the engine ⇒.
Coming Home and Leaving Home function (orientation lighting)
The Coming home and Leaving home functions illuminate the area directly next to the vehicle when
getting into and leaving the vehicle in darkness.
m/k/a995MK Not in China: the Coming Home function is switched on manually. However,
the Leaving Home function is controlled automatically by a rain/light sensor.
m/k/a995MK Only in China: the Coming Home and Leaving Home function is controlled
automatically by a rain/light sensor.
The switch-off delay can be set and the function can also be activated and deactivated in
the Vehicle settings menu ⇒ Operation and display in the Infotainment system in the
Infotainment system:
Accidents and serious injuries can occur if the vehicle is parked without sufficient
illumination, as other road users might have difficulty seeing the vehicle, or may not see it
at all.
•Always park the vehicle securely and with sufficient lighting. Observe any applicable
local legislation.
•If the vehicle lighting is required for several hours, switch on the right or left parking
light if possible. The illumination time of the one-sided parking light is generally double
that of the continuous parking light on both sides.
WARNING

The following systems may be installed in the vehicle
The heating and fresh air system warms up and supplies fresh air to the vehicle interior. The
heating and fresh air system does not cool down the vehicle interior.
The manual air conditioning system or Climatronic cools down and dehumidifies the air. It
works most effectively when the windows and the glass roof are closed. If heat has built up in the
vehicle interior, opening the doors and windows can speed up the cooling process.
How the vehicle displays active functions
Lit up LEDs on rotary knobs and buttons indicate that a function has been switched on.
Some settings can be stored in the user accounts of the personalisation function and
therefore change when the user account changes ⇒ Personalisation.
Front controls
Fig. 109 In the upper section of the centre console: controls for the manual air conditioning system.
Poor visibility through the windows increases the risk of collisions and accidents, which
can cause serious injuries.
•Keep all windows free of ice, snow and misting to ensure good visibility.
•Set the heating, air conditioning and rear window heating controls to prevent the
windows from misting up.
•Only set off once all door windows, the windscreen and the rear window are clear.
•Use air recirculation mode only for short periods. If the cooling system is switched off,
the windows can mist up very quickly in air recirculation mode and reduce visibility
considerably.
•Switch off the air recirculation mode when it is no longer required.
WARNING
Stale air can quickly make the driver tired and affect their concentration, which in turn can
cause collisions, accidents and serious injuries.
•Never switch off the blowers or switch on the air recirculation mode for longer periods
as this prevents fresh air from entering the vehicle interior.
WARNING
Do not place any food, medicine or any other temperature-sensitive items in front of the
vents. Heat-sensitive food, medicine and other items could be either damaged or rendered
useless.
NOTICE
If the air conditioning system is not working, switch the air conditioning system off
immediately and have it checked by a qualified workshop. This can help to prevent
secondary damage.
