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
In vehicles with a corresponding equipment level, main-beam control can be activated and
deactivated in the Infotainment system in the Vehicle settings menu ⇒ Operation and
display in the Infotainment system:

•OR: switch off the ignition.
•OR: push the turn signal and main beam lever forwards to switch on the manual main beam.
Advanced main-beam control (Dynamic Light Assist)
Advanced main-beam control provides maximum illumination for the road and the surrounding area.
At the same time, it prevents vehicles in front or oncoming vehicles from being dazzled. The system
uses a camera to detect other road users and their distance from your vehicle and covers part of
the headlights appropriately. If the system can no longer prevent other road users from being
dazzled, the main beams are switched off automatically.
System limits
The main beam must be switched off manually under the following conditions because it is not
switched off in time or not switched off at all by the main beam control:
•In poorly lit streets where there are highly-reflective signs.
•Other road users with insufficient lighting facilities, such as pedestrians, cyclists.
•In tight bends, brows of hills or depressions in the land or half-hidden oncoming traffic.
•With oncoming traffic on streets with a central barrier where the driver can see clearly over the
central barrier e.g. truck drivers.
•In fog, snow or heavy rain.
•In dusty or sandy areas.
•Damage to the windscreen in the camera's vision field.
•If the viewing field of the camera is misted up, dirty, covered by a sticker, snow or ice.
•If the camera is broken or the power supply is interrupted.
Light-emitting objects in the camera's field of operation, e.g. mobile navigation devices, could
impair the functions of the main-beam control system (Light Assist).
Parking light
Switching the parking lights on and off
Do not let the extra convenience afforded by main beam control tempt you into taking any
risks when driving – this can cause accidents. The system is not a substitute for the full
concentration of the driver.
•Always check the lights yourself and adjust them to the prevailing conditions for lights,
vision and road traffic.
•The main beam control may not be able to recognise all driving situations correctly and
may not work properly in certain situations.
•If the camera's field of view is dirty, covered or damaged, the function of the main
beam control may be impaired. This also applies if changes are made to the vehicle's
lighting system, for example if additional headlights are fitted.
WARNING
Please observe the following points in order to avoid impairing the proper function of the
system:
•Regularly clean the camera's field of view, and keep it free from snow and ice.
•Do not cover the camera's field of view.
•Regularly check the area of the windscreen that is in the camera's field of view for
damage.
NOTICE
•If the dynamic cornering light has been deactivated.
•If travel mode is activated ⇒ Switching over headlights for driving abroad (travel mode).
•When the Eco driving profile is selected in vehicles with driving profile selection ⇒ Driving
profile selection and 4MOTION Active Control.
Interior lighting
Instrument and switch lighting
The brightness of the instrument and switch lighting and the basic brightness level of the Head-up
Display ⇒ Instrument cluster can be adjusted in the Infotainment system in
the Vehicle settings menu ⇒ Operation and display in the Infotainment system.
The brightness setting is automatically adjusted to the changing light conditions in the vehicle.
When the light switch is in position , a sensor will switch the dipped beam and the lighting
in the instruments and switches on and off automatically depending on the ambient brightness
level.
When the light is switched off and the ignition switched on, the dash panel lighting (indicators
and scales) is switched on. As the ambient light becomes lower, the lighting of these scales is
automatically reduced and may be switched off entirely. This function is intended to remind the
driver to switch on the dipped beam in good time, i.e. when driving through tunnels.
Interior lights, reading lights, background lighting
Press the corresponding button:
Switches the front interior lights on or off.Switches the rear interior lights on or off.
The interior lights are switched on automatically when the vehicle is unlocked, a door is

off.
Stowage compartment and luggage compartment lights
A light will be switched on and off automatically when the stowage compartment on the front
passenger side, or the boot lid, is opened or closed.
Background lighting
Depending on the equipment level, the background lighting provides indirect light in the various
areas of the vehicle interior.
The footwell and, where applicable, the closed blind of the glass roof may also be illuminated.
The brightness of the background lighting can be adjusted in the Infotainment system in
the Vehicle settings menu ⇒ Operation and display in the Infotainment system.
The lights go out when the vehicle is locked or after a delay of a few minutes when the
vehicle key is removed from the ignition lock. This prevents the 12-volt battery from discharging.
Some settings can be stored in the user accounts of the personalisation function and
therefore change automatically when the user account changes ⇒ Personalisation.

Wipers
Operating the wiper lever
Fig. 101 On the steering column, right: operating the front windscreen wipers.
When parking the vehicle in cold weather, it may be helpful to leave the windscreen wipers in
the service position to make it easier to loosen the wiper blades ⇒ Wiper blades.
Wiper functions
Automatic activation of the rear window wiper
The rear window wiper is switched on automatically if the front windscreen wipers are switched on
and reverse gear is engaged. The automatic wipe function can be activated and deactivated in the
Infotainment system in the Vehicle settings menu ⇒ Operation and display in the
Infotainment system:
Heated washer jets
The heating defrosts frozen washer jets. The heating output is regulated automatically when the
ignition is switched on depending on the ambient temperature. Only the jets are heated and not the
hoses carrying the washer fluid.
Headlight washer system
The headlight washer system cleans the headlight lenses and only works when the vehicle lighting
is switched on.
Once the ignition has been switched on, the headlights will also be washed the first time the wash
and wipe system for the windscreen is used, and every tenth time thereafter. Hardened dirt, such
as insect remains, should be removed from the headlight lens at regular intervals.
In winter, you should remove any snow from the headlight washer system covers in the bumper
prior to use to keep the system in working order. Remove any ice with a de-icer spray.
Rain/light sensor
Fig. 103 On the right of the steering column: wiper lever.
When the rain/light sensor is activated, it automatically controls the frequency of the wiper intervals,
depending on the intensity of the rain.
Activating and deactivating the rain/light sensor
•Position Ⓐ - the rain/light sensor is deactivated.
•Position Ⓑ - the rain/light sensor is activated, automatic wipe when necessary.
The automatic wipe function can be activated and deactivated in the Infotainment system in
the Vehicle settings menu ⇒ Operation and display in the Infotainment system:
If the automatic wipe function is deactivated in the Infotainment system, the intervals are set at fixed
levels.
Setting the sensitivity of the rain/light sensor
The sensitivity of the rain/light sensor can be adjusted manually using the switch in the wiper lever
⇒ Fig. 103①⇒.
•Switch to the right – high sensitivity.
•Switch to the left – low sensitivity.
Some settings can be stored in the user accounts of the personalisation function and
therefore change automatically when the user account changes ⇒ Personalisation.
The rain/light sensor cannot always detect every rain shower and activate the windscreen
wipers.
•If necessary, switch on the windscreen wipers manually if the water on the windscreen
restricts the field of vision.
WARNING
Troubleshooting
Washer fluid level too low. Fill up the washer fluid reservoir as soon as possible ⇒ Washer
fluid.Fault in the rain/light sensor. Switch the ignition on and off. If the indicator lamp still lights
up permanently after you switch the ignition back on, seek expert assistance.Fault in
windscreen wipers. Switch the ignition on and off. If the indicator lamp still lights up permanently
after you switch the ignition back on, seek expert assistance.
Changes in the response of the rain/light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light
sensor ⇒ Vehicle overviews include:
•Damaged wiper blades: a film of water or smears caused by damaged wiper blades can
increase the time the wipers are switched on, can shorten the length of the intervals between
wipes or cause the wipers to run quickly and continuously.
•Insects: insects hitting the windscreen surface can cause the wipers to be activated.
•Salt deposits: in winter, salt deposits on the windscreen can cause the wipers to continue to
wipe the windscreen when it is almost dry.
•Soiling: dry dust, wax, windscreen coatings (lotus effect), or detergent deposits (from an
automatic car wash) can cause the rain/light sensor to become less sensitive and react too
slowly, or prevent it from reacting at all. Clean the sensitive surface of the rain/light sensor
⇒ Caring for and cleaning the vehicle exterior at regular intervals and inspect the wiper blades
for damage.
•Crack in the windscreen: a wipe cycle will be triggered if the rain/light sensor is on when the
windscreen is impacted by a stone. The rain/light sensor will then register the reduction in
sensitivity of the surfaces and adjust accordingly. The size of the crack can affect the way in
which the rain/light sensor activates the wipers.
We recommend that you use an alcohol-based glass cleaner to remove wax and polish.
The wipers will try to wipe away any obstacles that are on the windscreen. The wipers will
stop moving if the obstacle blocks their path. Remove the obstacle and switch the wipers back on
again.
Mirrors
Introduction
This chapter contains information on the followingsubjects:
⇒ Interior mirror
⇒ Exterior mirrors
You can use the exterior mirrors and the interior mirror to observe traffic behind you and adjust
driving style accordingly.
For safety reasons it is important that the driver positions the exterior and interior mirrors correctly
before starting a journey ⇒.
Looking in the exterior mirrors and the interior mirror does not allow the driver to see the entire side
and rear area of the vehicle. The area that cannot be seen is known as the blind spot. There may
be objects and other road users in the blind spot.
Adjusting the exterior and interior mirrors while driving may cause the driver to become
distracted. This can lead to accidents and serious injuries.
•Exterior and interior mirrors should only be adjusted when the vehicle is stationary.
•When parking, changing lane, or performing an overtaking or turning manoeuvre,
always pay careful attention to the area around the vehicle as objects and other road
users may be located in the blind spot.
•Always ensure that the mirrors are positioned correctly and that the rear view is not
restricted by ice, snow, condensation or any other objects.
WARNING
If you estimate the distance from traffic behind you incorrectly, you can cause accidents
and serious injuries.
•Curved mirrors (convex or aspheric) enlarge the field of vision and can make objects in
the mirror seem smaller and further away than they actually are.
•Using curved mirrors to estimate the distance from other vehicles behind you when
changing lanes can provide inaccurate results and can lead to accidents and severe
injuries.
•Whenever possible, use the interior mirror to check the exact distance between your
vehicle and following traffic or other objects.
•Ensure that you have a good view to the rear of the vehicle.
WARNING
The auxiliary heater runs on for a short time after it is switched off manually or automatically so that
the remaining fuel in the system can be burnt off.
When the vehicle is at a standstill, the auxiliary heater can be activated up to three times in
succession for the maximum operating duration.
Operating noises can be heard if the auxiliary heater is switched on.
The 12-volt battery will discharge if the auxiliary heater or ventilation is run several times
over an extended period. Drive the vehicle for an appropriate distance in order to recharge the 12-
volt vehicle battery.
When parked on an incline, the fuel gauge indication (just above the reserve quantity) may
be inaccurate and lead to functional restrictions of the auxiliary heater.
The auxiliary heater may switch on automatically as a supplementary heating measure when
the engine is started at temperatures below +5°C (+41°F). The supplementary heating function is
switched off again automatically after a short time.
