Automatic headlamp control
Switch
position : the low beams are switched
on and off automatically, e.g., in tunnels, in twi‐
light 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 judgment
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 un‐
der 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

Roadside parking lamps 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. Switching off
Briefly press the lever to the resistance point in
the opposite direction.
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.
Controls
Activating
Switch position
with the ignition switched
on.
The turning lamps are automatically switched
on depending on the steering angle or the use
of turn signals.
To

avoid blinding oncoming traffic, the adaptive
light control directs light towards the front pas‐
senger side when the vehicle is at a standstill.
When driving in reverse, only the turning lamp is
active.
Self-leveling headlights
The self-leveling headlights feature adapts the
light distribution to the contours of the road.
The light distribution is lowered on hilltops to
avoid blinding oncoming traffic and tilted in de‐
pressions to increase visibility.

▷
Make sure that the front passenger is sitting
correctly, i.e., keeps his or her feet and legs
in the footwell; otherwise, leg injuries can
occur if the front airbag is triggered.
▷ Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.
▷ Do not hang pieces of clothing, such as jack‐
ets, over the backrests.
▷ Make sure that occupants keep their heads
away from the side airbag; otherwise, inju‐
ries can occur if the airbags are deployed.
▷ Do not remove the airbag restraint system.
▷ Do not remove the steering wheel.
▷ Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.
▷ Never modify either the individual compo‐
nents
or the wiring in the airbag system. This
also applies to steering wheel covers, the
dashboard, and the seats.◀
Even when all instructions are followed closely,
injury from contact with the airbags cannot be
ruled out in certain situations.
The ignition and inflation noise may lead to
short-term

and, in most cases, temporary hear‐
ing impairment in sensitive individuals.
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in injury.◀
Warnings and information on the airbags are
also found on the sun visors. Functional readiness of the airbag
system
When

the ignition is switch on, the warn‐
ing lamp in the instrument cluster lights
up briefly and thereby indicates the op‐
erational readiness of the entire airbag system
and the belt tensioner.
Airbag system malfunctioning
▷ In radio ready state, the warning lamp does
not come on.
▷ The warning lamp lights up continuously.
When there is a malfunction, have the air‐
bag system checked immediately
When there is a malfunction, have the airbag
system checked immediately; otherwise, there
is

a risk that the system does not function as ex‐
pected in the event of an accident despite cor‐
responding severity of the accident.◀
Automatic deactivation of the front
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body.
The front, knee, and side airbag on the front
passenger side are activated or deactivated ac‐
cordingly.
Leave feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, the front
passenger airbags may not function properly.◀
Child restraint fixing system in the front
passenger seat
Before transporting a child on the front passen‐

Rollover protection system
The concept
The
rollover protection system is activated dur‐
ing an accident or a critical driving situation,
when there is extreme tilt with respect to the
longitudinal axis or when there is loss of ground
contact. The safety frames located behind the
rear headrests extend within fractions of a sec‐
ond.
In addition to the rollover bracket integrated in
the front windshield frame, the rollover protec‐
tion system guarantees the required head clear‐
ance of all vehicle occupants.
Maintaining movement space
Always keep the movement space of the
rollover protection system clear. Otherwise,
there may be damage or injuries when the roll‐
over protection system is triggered.◀
In less severe accidents, the secured safety belt
and, depending on the severity of the accident,
the belt tensioner and airbag restraint system
provide protection.
Triggered rollover protection system
After deployment or damage
After deployment of the rollover protec‐
tion system or in the event of damage, have the
system checked and replaced.
Have this work performed only by your service
center; otherwise, it cannot be ensured that this
safety feature will function properly.◀
Do not move convertible top
When the rollover protection system is ex‐
tended, do not move the convertible top. Oth‐
erwise, damages or injuries may result.◀
If the rollover protection system was not placed
under any stress after an automatic triggering, it
can be pushed back by hand, e.g. to close the
convertible top. Three people are necessary for
this. 1.
Push the lever to the side and hold it in this
position. 2.
Push down the safety frame.
3. Release lever.
4. Hold down the safety frame.
5. Proceed likewise with the second safety
frame.
6. Close the convertible top
In the event of malfunctions, deactivation
or after deployment
Only have the airbags checked, repaired or dis‐
mantled

and the system scrapped by your serv‐
ice center. Non-professional attempts to service
the system could lead to failure in an emergency
or undesired triggering of the airbag, either of
which could result in injury.◀
Malfunction
A Check Control message is displayed
when there is a malfunction.
Tire Pressure Monitor TPM*
The concept
The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.
Functional requirements
The system must have been reset when the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured. Always use
wheels with TPM electronics to ensure that the Seite 91
