Introduction
This chapter contains information on the followingsubjects:
Folding the backrests on the rear bench seat forwards and backwards
The following section describes the options for adjusting the rear seats. Always ensure that you
adjust the correct sitting position Sitting position
WARNING
Incorrect adjustment of the rear seat can cause accidents and serious injuries.
The rear seat should be adjusted only when the vehicle is stationary as the rear seat could otherwise
move unexpectedly while the vehicle is in motion. Furthermore, an incorrect seating position is
adopted while adjusting the seat.
Adjust the rear seat only when there is no one in the adjustment area of the rear seats.
WARNING
Cigarette lighters left in the vehicle can become damaged or may ignite unnoticed. This can cause
serious burns and vehicle damage.
Before adjusting the seats, always make sure that there is no lighter on or near the moveable parts
of the seat.
Before closing stowage areas or compartments, always make sure that there is no lighter in the way.
Never stow lighters in stowage areas, compartments or on other surfaces in the vehicle. Cigarette
lighters may self-ignite as a result of high surface temperatures, particularly in summer.
WARNING
In order to reduce the risk of injury while the vehicle is in motion, the centre armrest must always be
folded up and the stowage compartment must be closed.
The middle seat on the rear bench seat must never be used when the centre armrest is folded down
neither by adults nor children. An incorrect sitting position can cause serious injuries.
Never transport an adult or child on the centre armrest.
Close the stowage compartment only when there is no one in its closing path.
NOTICE
WARNING
Incorrect use of turn signals, a failure to use turn signals, or forgetting to switch off a turn signal can
confuse other road users. This could lead to accidents and serious injuries.
Always activate the turn signal in good time when changing lanes and performing overtaking or
turning manoeuvres.
Always switch off the turn signal once the lane change or overtaking or turning manoeuvre has been
completed.
The hazard warning lights also work when the ignition is switched off In an emergency
Some settings can be stored in the user accounts of the personalisation function and therefore

Daytime running lights
The daytime running lights (dependent on equipment level) can increase the visibility of your vehicle
in traffic during the day.
The daytime running lights are switched on every time the ignition is switched on when the light
switch is in position , or (when brightness is detected).
The daytime running lights cannot be switched on or off manually.
WARNING
Accidents and serious injuries can occur if the road is not sufficiently illuminated and other road
users have difficulty seeing the vehicle, or cannot see it at all.
The light assist systems are designed only to provide support; the driver is responsible for the
correct vehicle lights being switched on.
Always switch on the dipped beam headlights 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 on the dipped beam headlights if it is dark, raining or visibility is poor.
The tail light clusters are not switched on with the daytime running lights. If the tail light clusters 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

Switching main beam on and off
Fig. 80 On the left of the steering column: turn signal and main beam lever.
Switch on the ignition and dipped beam.
Move the turn signal and main beam lever from the centre position to the following position:
Main beam switched on.
Operate the headlight flasher or switch off the main beam. The headlight flasher comes on for as
long as the lever is pulled.
When the main beam or headlight flasher are switched on, the blue indicator lamp lights up in
the instrument cluster.
Main-beam control
Depending on the vehicle equipment level, advanced main-beam control may also be available
Main-beam control
WARNING
Incorrect use of the main beam headlights can lead to accidents and serious injuries as the main
beam headlights could distract and dazzle other road users.
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 also recognises illuminated areas such as towns
and deactivates the main beam while driving through them.
Within the limits of the system, main-beam control automatically switches 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)
With some equipment levels, the main-beam control can be activated and deactivated in the
Infotainment system in the Vehicle settings menu Infotainment system controls and displays
Switching on main-beam control
matic headlights .
Tap the turn signal and main beam lever forwards from the basic position.
When main-beam control is switched on, the indicator lamp lights up in the instrument cluster
display.
Switching off main-beam control
Pull back the turn signal and main beam lever.
OR: switch off the automatic headlights .
OR: switch off the ignition.
OR: push the turn signal and main beam lever forwards to switch on the manual main beam.
System limits
The main beam must be manually switched off under the following conditions, as it is not switched
off by the main-beam control in time or at all:
In poorly lit streets where there are highly-reflective signs.
Other road users with insufficient lighting facilities, such as pedestrians, cyclists.
In tight bends, with half-hidden oncoming traffic, on steep crests or in dips.
With oncoming traffic on roads 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 conditions with swirled-up dust and sand.
If the windscreen is damaged in the camera's field of vision.
If the camera's field of vision is covered by condensation, dirt, a sticker, or by snow or ice.
If the camera is faulty or the power supply is interrupted.
WARNING
Do not let the extra convenience afforded by main-beam control tempt you into taking any risks
when driving. The system is not a substitute for the full concentration of the driver.
Always check the vehicle lights yourself and adapt them to the prevailing conditions for light,
visibility 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.
Lock the vehicle from the outside.
Automatic switch-off of side lights and parking lights
If the battery capacity is not sufficient for the side lights or parking light to remain switched on for
two hours, the 12-volt vehicle battery can be discharged to such an extent that it is no longer
possible to start the engine
In the case of standing times of more than two hours, the vehicle will detect a weak 12-volt vehicle
battery and switch off the side lights or parking light so that the engine can still be started.
WARNING
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 safely and with sufficient lighting. Observe any applicable local regulations.
If the vehicle lighting is required for several hours, switch on the right or left parking light if possible.
The illumination time of the parking light on one side is generally twice as long as for continuous
parking light on both sides of the vehicle.
Coming Home and Leaving Home function (orientation lighting)
The Coming Home and Leaving Home function lights up the area immediately surrounding the
vehicle when you get in or out of the vehicle in darkness.
Not in China: the Coming Home function is switched on manually. In contrast, the Leaving
Home function is controlled automatically by a rain/light sensor.
Only in China: the Coming Home and Leaving Home function is controlled automatically by a
rain/light sensor.
The switch-off delay can be adjusted and the function activated or deactivated in the Vehicle
settings menu in the Infotainment system Infotainment system controls and displays

are switched on
WARNING
Heavy objects in the vehicle can cause the headlights to dazzle and distract other road users. This
could lead to accidents and serious injuries.
The light cone should always be adjusted to the load level of the vehicle to ensure that other road
users are not dazzled.
