WARNING
The car's audio system is not able to deter- mine when daylight is too weak or sufficientlystrong, e.g. in fog and rain, in all situations. The driver is always responsible for ensuring that the car is driven with a beam pattern suit-able for the traffic situation and in accordancewith applicable traffic regulations.
Thumbwheel in the instrument panel
Thumbwheel for adjusting interior brightness
Thumbwheel for headlamp levelling
A car with LED 21
headlamps * has automatic
headlamp levelling and therefore does not have the thumbwheel for headlamp levelling.
Adjusting the interior brightness
The lamps inside the car come on differently depending on the ignition position used. The thumbwheel adjusts the brightness of display lighting, control lighting, ambient light and ambi- ence light *.
Headlamp levelling
The load in the car changes the vertical align- ment of the headlamp beam, which could dazzleoncoming motorists. Avoid this by adjusting theheight of the beam. Lower the beam if the car isheavily laden. For different load cases and settings, see the section "Headlamp levelling".

is adjusted using one of
the thumbwheels in the instrument panel.
1. Leave the engine running, or have the car's
electrical system in ignition position I.
2. Roll the thumbwheel up/down to raise/lower beam alignment.

Position lamps
The position lamps are switched on with the rotating ring on the stalk switch.
Stalk switch rotating ring in position lamps position.
Turn the rotating ring to the position - the
position lamps are switched on (number plate lighting is switched on at the same time). If the car's electrical system is in ignition position II or the car is running then the daytime running
lights are switched on instead of the front posi-tion lamps. However, this does not apply at sta-
tionary when the car is running, if the rotating
ring is moved to position
from another
position . In this case, the position lamps are
switched on. If the tailgate is opened when it is dark outside, the rear position lamps come on (if not alreadyswitched on) to warn road users approaching from behind. This takes place irrespective of theposition of the rotating ring or the ignition posi-tion of the car's electrical system. When driving for more than 30 seconds at max. 10 km/h (approx. 6 mph), or if the speedexceeds 10 km/h (approx. 6 mph), the daytimerunning lights are switched on. The driver should turn to a position other than

Daytime running lights The daytime running lights are switched on when the rotating ring on the stalk switch is in position
, or as well as when
the car's electrical system is in ignition position II
or when the car is running. For the
posi-
tion, this only applies in daylight. In weak daylight or darkness, dipped beam is switched oninstead.
Daytime running lights during the day.
DRL
Stalk switch rotating ring in AUTO position.
If the stalk switch rotating ring is in the position, the daytime running lights (Daytime Running Lights - DRL) are switched on when thecar is driven in daylight. The car automaticallychanges lighting from daytime running light todipped beam in weak daylight or darkness. Changing to dipped beam also takes place if thefront fog lamp and/or rear fog lamp are activated. At
stationary when the car is running, the posi-
tion lamps are switched on instead of other light- ing, if the rotating ring is moved to the position for position lamps,
, from another position .
WARNING
This system help to save energy - it cannot determine in all situations when daylight is tooweak or sufficiently strong, e.g. in mist andrain. The driver is always responsible for ensuring that the car is driven with the correct beampattern for the traffic situation and in accord-ance with applicable traffic regulations.

automatically in weak daylight or darkness.
Stalk switch rotating ring in AUTO position.
With the stalk switch's rotating ring in the position, dipped beam is activated automatically in weak daylight or darkness, when the car's electrical system is in ignition position II or when
the car is running. With the stalk switch's rotating ring in
position, dipped beam is also activated automati- cally if:

Active main beamActive main beam is a function which uses a camera sensor at the top edge of the windscreento detect the headlamp beams from oncomingtraffic or the rear lights of vehicles in front, andthen switches from main beam to dipped beam.The function can also take streetlights intoaccount. Main beam is reactivated when the camera sen- sor no longer sees any oncoming vehicles orvehicles ahead.
Car with halogen headlamps
The lighting returns to main beam about a sec- ond after the camera sensor no longer detectsthe headlamp beams from oncoming traffic or therear lights from vehicles in front.

Cornering lightsThe front fog lamps include the cornering lights function, which temporarily illuminates the areadiagonally in front of the car in the direction thesteering wheel is turned on a sharp bend, or inthe direction shown by the direction indicators. The function is activated in weak daylight or dark- ness when the stalk switch's rotating ring is in the
or position and the speed of the
car is lower than approx. 30 km/h (20 mph). In addition, both cornering lights are switched on as a supplement to the reversing lamp duringreversing. The function is activated when the car is supplied from the factory and can be deactivated/acti-vated via the centre display.
