Headlight courtesy delay featureThe low beams stay lit for a short while after
the radio-ready state is switched off if the
lights are turned off and the headlight flasher is
switched on.
Setting the duration
On the Control Display:1."Settings"2."Lighting"3."Pathway lighting:"4.Set length of time.
Settings are stored for the profile currently in
use.
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
, or
. After the ignition is switched off, the park‐
ing 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.

Commission regulations. Operation is gov‐
erned by the following:
FCC ID:▷NBG009014A.
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Brake force display
The concept
▷During normal brake application, the outer
brake lights light up.▷During heavy brake application, the inner
brake lights light up in addition.
Active Protection
General information
The Active Protection safety package consists
of systems that are independent of each other:
▷Attentiveness assistant.▷PreCrash▷PostCrash
Attentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, e.g., on highways. In this situation, it is recommended that the driver
takes a break.
Note Personal responsibility
The system cannot act as a substitute for
the personal assessment of one's physical
state and may not detect an increasing lack of
alertness or fatigue or may not detect it cor‐
rectly. Therefore, make sure that the driver is
rested and alert; otherwise, risks may be de‐
tected too late and an accident be caused as a
result.◀
Function
The system is activated each time the engine
is started and cannot be switched off.
After travel has begun, the system is trained
about the driver, so that increasing lack of
alertness or fatigue can be detected.
This procedure takes the following criteria into
account:
▷Personal driving style, e.g., steering behav‐
ior.▷Driving conditions, e.g., length of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.

Caring for the convertible topThe appearance and life of the convertible top
depend on correct care and operation.
Note the following instructions:▷To prevent water stains, mildew spots, and
chafe marks, do not enclose the
convertible top in the convertible top well
for a long period and do not fold and stow
the convertible top in the convertible top
well while the top is wet or frozen.▷Remove water stains that may neverthe‐
less have appeared on the roofliner using a
microfiber cloth and an interior cleaner.▷When the vehicle is parked in enclosed
areas for lengthy periods, ensure that the
area is well ventilated.▷If possible, park the vehicle in the shade to
protect it from intensive solar radiation so
that color, rubber and fabric are not af‐
fected.▷Remove bird droppings immediately as
their corrosive effect will otherwise attack
the convertible top and damage the rubber
seals.▷Hard to remove tree sap or bird droppings
can be removed from the convertible top
with special tree sap remover and a soft
brush.
Do not use spot remover
Do not use spot remover, paint thinner,
solvent, gasoline, or similar products to re‐
move spots on the convertible top. These
products may destroy the rubber coating. In‐
correct care and cleaning may cause the
convertible top and its seams to become
leaky.◀
To remove heavy soiling, especially for light
colored convertible tops, use a special
convertible top cleaner.
Proceed as follows:
1.Spray the convertible top with the
convertible top cleaner.2.Make the convertible top cleaner foam up
using a well saturated sponge, moving it in
circular motions.3.Finish washing the vehicle in the car wash
or rinse with ample amounts of water.
Otherwise, follow the instructions for use from
the manufacturer.
Treat the convertible top with an impregnating
agent after it has been washed three to five
times.
Suitable cleaners and car products can be ob‐
tained from the service department.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.
Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every
two months.
Clean light-colored leather more frequently be‐
cause soiling on such surfaces is substantially
more visible.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.
Upholstery material care Vacuum regularly with a vacuum cleaner.
If upholstery is very dirty, e.g., with beverage
stains, use a soft sponge or microfiber cloth with a suitable interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the
material vigorously.
