▷When locking the vehicle, and when the
low beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available
when the low beams are turned off.▷When opening and closing the driver door,
if the driver's safety belt is unbuckled and
the low beams are turned off.▷While the driver's safety belt is unbuckled
with driver's door open and low beams off.
The low beams reel to parking lights after ap‐
prox. 15 minutes of no use.
When the ignition is switched off automatically
by opening or closing the driver's door, un‐
buckling the driver's safety belt or by the auto‐
matic switching of the low beams to parking
lights, the radio-ready state remains active.
Drive readiness
When drive readiness is activated, the vehicle
is operational. Activated drive readiness is the
equivalent of a running engine in conventional
vehicles. Deactivated engine readiness is
equivalent to switching the ignition off.
Drive readiness in detail
The concept
The following are the different drive readiness
variants:
▷Electric drive readiness, Silent Start, refer
to page 76
The vehicle is powered by the electric mo‐
tor.▷Starting the combustion engine, refer to
page 76
The vehicle is powered by the combustion
engine.Hints
Do not leave the vehicle unattended
Do not leave the vehicle unattended with
drive readiness active; otherwise, it may pose a
risk.◀
Awareness of vehicle reduced when
driven in electric mode
When driving in electric mode, note that due to
the lack of engine noise pedestrians and other traffic might pay less attention to the vehicle
due to missing engine noises. Please take spe‐
cial care when parking or leaving a parking
space.◀
Activating drive readiness1.Close the driver's door.2.Depress the brake pedal.3.Press the Start/Stop button.
Drive readiness is activated:
▷Electric drive readiness, Silent Start or▷Starting the combustion engine.
Electric drive readiness, Silent Start The vehicle is ready for driving without starting
the combustion engine.
Silent Start is possible if the requirements for
Electric driving, refer to page 78, are met.
Display READY indicates drive readi‐
ness.
Starting the combustion engine Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀

General information
Position of switch: 0,
,
If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these reel settings.
Parking lights
Position of switch
: the vehicle's lights
light up on all sides, e.g., for parking.
Do not use the parking lights for extended pe‐
riods; otherwise, they might drain the battery
and it would then be impossible to start the en‐
gine.
When parking, it is preferable to reel on the
one-sided roadside parking lights, refer to
page 108.
Low beams Position of switch
with the ignition
switched on: the low beams light up.
Welcome lights
When parking the vehicle, leave the reel in po‐
sition
or : the parking and interior
lights light up briefly when the vehicle is un‐
locked.

Automatic headlight control
Position of switch
: the low beams are acti‐
vated and off automatically, e.g., in tunnels, in
twilight or if there is precipitation. The indicator
lamp in the instrument cluster lights up.
When emerging from a tunnel during the day,
the low beams are not switched off immedi‐
ately but instead only after approx. 2 minutes.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams always stay on when the fog
lights are activated.
Personal responsibility
The automatic headlight control cannot
serve as a substitute for your personal judg‐
ment in determining when to turn the lights on
in response to ambient lighting conditions.
E. g. the sensors are unable to detect fog or
hazy weather. To avoid safety risks under
these conditions, you should always switch on
the lights manually.◀
Daytime running lights With the ignition switched on, the daytime run‐
ning lights light up in position 0,
or .
After the ignition is switched off, the parking
lights light up in position
.
Activating/deactivating
In some countries, daytime running lights are
mandatory, so it may not be possible to deacti‐
vate the daytime running lights.
On the Control Display:1."Settings"2."Lighting"3."Daytime running lamps"
Settings are stored for the profile currently in
use.
Roadside parking lights
The vehicle can be illuminated on one side.
Switching on With the ignition switched off, press the lever
either up or down past the resistance point for
approx. 2 seconds.
Switch off Briefly press the lever to the resistance point in
the opposite direction.
Adaptive Light Control The concept
Adaptive Light Control is a variable headlight
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐ rameters, the light from the headlight follows
the course of the road.
In tight curves, e.g., on mountainous roads or
when turning, an additional, corner-illuminating
lamp is switched on that lights up the inside of
the curve when the vehicle is moving below a certain speed.

ActivatingPosition of switch
with the ignition
switched on.
To avoid blinding oncoming traffic, the Adap‐
tive Light Control does not swivel to the driv‐
er's side when the vehicle is at a standstill.
The turning lights are automatically switched
on depending on the steering angle or the use
of turn signals.
When driving in reverse, the turning lights may
be automatically switched on regardless of the
steering angle.
Self-leveling headlights The self-leveling headlights compensate for
acceleration and braking operations in order
not to blind the oncoming traffic and to achieve
optimum illumination of the roadway.
Malfunction A Check Control message is displayed.
Adaptive Light Control is malfunctioning or has
failed. Have the system checked as soon as
possible.
High-beam Assistant
The concept When the low beams are activated, this system
automatically switches the high beams on and
off or suppresses the light in the areas that
blind oncoming traffic. The procedure is con‐
trolled by a camera on the front of the interior
rearview mirror. The assistant ensures that the
high beams are activated whenever the traffic
situation allows. The driver can intervene at
any time and reel the high beams on and off as
usual.
Activating1.Depending on the equipment, turn the light
switch into position
or .
2.Press button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster lights up.
When the low beams are on, the lights are au‐
tomatically brightened or dimmed.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams. Depend‐
ing on the version of the system in the vehicle, the high beams may not reel off for oncoming
vehicles, but may only be dimmed in the areas
that blind oncoming traffic. In this case, the blue indicator light will stay on.
