between wipes depending on the intensity of the rainfall. The sensor is located on the wind‐
shield, directly behind the interior rearview mir‐
ror.
Activating/deactivating
Press the button on the wiper lever.
The LED in the wiper lever lights up and a wip‐
ing operation is started. At temperatures below
32 ℉/0 ℃, a wiping operation is not started.

Rain sensor, sensitivity
Turn the thumbwheel.
Clean the windshield, headlamps
Pull the wiper lever.
The system sprays washer fluid on the wind‐
shield and activates the wipers briefly.
In addition, the headlamps are cleaned at regu‐
lar intervals when the vehicle lights are
switched on.
Do not use the washer system at freezing
temperatures
Do not use the washers if there is any danger
that the fluid will freeze on the windshield; oth‐
erwise, your vision could be obscured. For this
reason, use antifreeze.
Avoid using the washer when the reservoir is
empty; otherwise, you could damage the
pump.◀
Windshield washer nozzles
The windshield washer nozzles are automati‐
cally heated while the ignition is switched on.

▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
Gears will only be shifted at appropriate engine
and road speeds, e.g., downshifting is not pos‐
sible if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
Shift lights in the instrument display
The concept Shift lights display the optimum shift point for
sport displays in the multifunction instrument
display. Thus, with a sporty driving style, the
best possible vehicle acceleration is achieved.
Display in the instrument display
▷Current engine speed is displayed in the
tachometer.▷Arrow 1: successive yellow illuminated
fields indicate the upcoming upshift mo‐
ment.▷Arrow 2: fields are illuminated in red. Do
not wait any further to shift.
When the maximum possible speed is
reached, the entire display flashes. When the
maximum speed is exceeded, the supply of
fuel is interrupted in order to protect the en‐
gine. Speeds in this range must be avoided.

A Check Control message is displayed as a
combination of indicator or warning lamps and
text messages in the instrument cluster and in
the Head-up Display.In addition, an acoustic signal may be output and a text message may appear on the Control
Display.

up on all sides, e.g., for parking.
Do not use the parking lamps for extended pe‐
riods; otherwise, the battery may become dis‐
charged and it would then be impossible to
start the engine.
When parking, it is preferable to switch on the
one-sided roadside parking lamps, refer to
page 92.

Automatic headlamp control
Switch position
: the low beams are
switched on and off automatically, e.g., in tun‐
nels, in twilight or if there is precipitation. The
indicator lamp in the instrument cluster lights
up.
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
lamps are switched on.
Personal responsibility
The automatic headlamp control cannot
serve as a substitute for your personal judg‐
ment in determining when the lamps should be
switched on in response to ambient lighting
conditions.
For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks, you
should always switch on the lamps manually
under these conditions.◀
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
lamps light up in position

Adaptive light control The concept Adaptive Light Control is a variable headlamp
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐ rameters, the light from the headlamp 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.

The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
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.
When driving in reverse, only the turning lamp
is active.
Self-leveling headlamps The self-leveling headlamps 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 switched on, this sys‐
tem automatically switches the high beams on
and off. The procedure is controlled by a sen‐
sor on the front of the interior rearview mirror.
The assistant ensures that the high beams are
switched on whenever the traffic situation al‐
lows. The driver can intervene at any time and
switch the high beams on and off as usual.Activating1.Turn the light switch to or .2.Press the button on the turn signal lever,

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.
