Tips about the convertible top:▷If possible, close the convertible top when
the vehicle is parked. A closed convertible
top protects it from weather-related dam‐
age and to some extent from theft.▷Event when the convertible top is closed,
only store valuables in the locked cargo area.▷At higher speeds, vacuum produced in the
passenger compartment cause the
convertible top to begin to flatten. Increase
the amount of air via the automatic climate
control so that no vacuum is produced in the
vehicle.
Notes
The trunk lid cannot be opened if the convertible
top is not fully opened or closed.
Safety information about the convertible
top
▷With temperatures below +14 ℉/-10 ℃ do
not open the convertible top; otherwise
damages could result.▷Do not leave the open convertible top in the
convertible top well longer than one day
while the top is still wet; otherwise, damage
could result due to moisture.▷The convertible top pivots up during open‐
ing and closing. When the top is moved, e.g.
in garages, make sure that there is a mini‐
mum height of 79 inches/2 meters; other‐
wise, it damages may result.▷Do not place any objects on the convertible
top, otherwise, they could fall and cause
damage or injuries.▷When the rollover protection system is ex‐
tended, do not under any circumstances
move the convertible top.▷Always open or close the convertible top
completely. Convertible top and convertible
top well storage cover are locked in the final
positions. Driving with the convertible tope
or convertible top well storage cover un‐
locked can result in damage.▷Do not reach into the convertible top mech‐
anism during the opening and closing oper‐
ation. Keep children away from the opening
path of the convertible top, otherwise, there
is a risk of injury.▷When the convertible top is opened during
driving, be alert to traffic; otherwise, it may
result in an accident. If possible, do not move
the convertible top while driving in reverse
because rearward vision is severely im‐
paired while the convertible top is in motion.
During windy conditions, do not operate the
convertible top while driving. Do not drive
faster than 30 mph/50 km/h; otherwise, ve‐
hicle damage may occur.▷Do not attach any roof carrier systems; oth‐
erwise, an accident may occur.◀

the convertible top simultaneously. When the
engine is started, the convertible top movement
is briefly interrupted.
Under the following conditions, the convertible
top movement cannot be moved and a Check
Control message is displayed.
▷Cargo area partition is flipped up.▷Trunk lid is open.▷External temperature is too low.▷Vehicle system too low.▷Convertible top drive is overheating.▷Movement of the convertible top not al‐
lowed because of national regulations.▷Vehicle speed is too high.
Before opening and closing
▷Follow the safety instructions for the

tours reduces muscular tension and fatigue to
help prevent lower back pain.
Press the button. The LED lights up.
Front seat heating
Switching on Press the button once for each temper‐
ature level.
The maximum temperature is reached when
three LEDs are lit.
If the drive is continued within approx. 15 mi‐
nutes, the seat heating is activated automati‐
cally with the temperature selected last.
When ECO PRO, refer to page 170, is activated,
the heater output is reduced.
Switching off Press the button longer.
The LEDs go out.
Temperature distribution
The heating action in the seat cushion and back‐
rest can be distributed in different ways.1."Climate"2."Seat heating distribution"3.Select the required seat.4.Turn the controller to set the temperature
distribution.
Active seat ventilation, front
The seat cushion and backrest surfaces are
cooled by means of integrated fans.
The ventilation rapidly cools the seat, e. g., if the
vehicle interior is overheated or for continuous
cooling at high temperatures.
