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

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.
NOTICE
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.
Light-emitting objects in the camera's field of operation, e.g. mobile navigation devices, can impair
the functions of the main-beam control system.

Lit up or flashing
orangeThe button cell (battery) in the remote control is weak. Replace the button cell.
Range
The remote control has a range of a few hundred metres when the button cell is fully charged.
Maintain a distanced of at least 2 metres between the remote control and the vehicle.
Avoid any obstacles between the remote control and the vehicle.
Hold the remote control with the aerial Fig. 93pointing vertically upwards.
Do not cover the aerial.
Adverse weather or a weak battery cell will significantly reduce the range.
Renewing the button cell in the remote control
The button cell in the remote control must be replaced if the indicator lamp does not light up.
Insert a suitable object, e.g. a screwdriver, in the recess on the side in the direction of the arrow
Fig. 93
Use the object to lever off the battery cover.
Slide the battery cover forwards slightly in the direction of the arrow.

Ignition switched on warning
A warning message appears in the instrument cluster display if the driver door is opened while the
ignition is switched on. A signal tone may also be given.
The warning is a reminder that the ignition must be switched off before leaving the vehicle.
WARNING
Improper or unsupervised use of the vehicle keys can cause accidents or serious injuries.
Always take all vehicle keys with you every time you leave the vehicle. The engine can be started and
electrical equipment such as the window controls can be operated. This can cause serious injury.
Never leave children or people requiring assistance alone in the vehicle when the vehicle is locked.
They could become trapped in the vehicle in an emergency and may not be able to get themselves
to safety. For example, locked vehicles may be subjected to very high or very low temperatures
depending on the season. This can cause serious injuries and illness or fatalities, especially in the
case of small children.
Never remove the vehicle key from the ignition if the vehicle is in motion. The steering column lock
may be activated and you will no longer be able to steer the vehicle.
