Functional requirements
The ignition or radio-ready state must be
switched on.
The following requirements must be fulfilled in
order to be able to move the hardtop.
▷The trunk partition is flipped down.▷The loading aid, refer to page 147, is shut
down.▷The trunk lid is closed.▷The external temperature is above
14 ℉/-10 ℃.▷The voltage of the vehicle electrical system
is sufficient.▷The hardtop drive is not overheating.▷The vehicle speed is not too high.▷The lateral tilt of the vehicle is not too
great.▷The windows can be lowered.
If this requirement is not met, a check control
message is displayed.
Safety information
Note the swivel range of the hardtop
The hardtop pivots back and up during
opening and closing. When the hardtop is
moved, e.g., in garages, make sure that the
space at the top is at least 79 inches/2 meters
and the space at the rear is at least 20 in‐
ches/50 centimeters; otherwise, damages may
result.◀
Do not place objects on the hardtop
Do not place any objects on the hardtop,
otherwise, they could fall and cause damage or
injuries.◀
No hardtop movement when rollover pro‐
tection is activated
Do not move the hardtop when rollover protec‐
tion is activated; otherwise, it may result in
damage to the hardtop.◀
Open and close hardtop completely
Always open or close the hardtop com‐
pletely. Hardtop and hardtop well storage
cover are locked in the final positions. Driving
with the hardtop or hardtop well storage cover
unlocked can result in damage.◀
Do not reach into the hardtop mecha‐
nism
Do not reach into the hardtop mechanism dur‐
ing the opening and closing operation. Keep
children away from the opening path of the
hardtop, otherwise, there is a risk of injury.◀
Observe traffic during operation
When the hardtop is opened while driv‐
ing, be alert to traffic; otherwise, it may result in
an accident. If possible, do not move the hard‐
top while driving in reverse because rearward
vision is severely impaired while the hardtop is
in motion. During windy conditions, do not op‐
erate the hardtop while driving.◀Seite 47Opening and closingControls47

cally:▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be

following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
If the engine is switched off and the ignition is
switched on, the system automatically
switches to the radio-ready state if the lights
are turned off or, if correspondingly equipped,
the daytime running lights are activated.
Starting the engine
Hints 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.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and engage trans‐
mission position P; otherwise, the vehicle may
begin to move.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the
fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving at
moderate engine speeds.

ometer signals that the Auto
Start/Stop function is ready to
start the engine automatically.
The display indicates that the
conditions for an automatic en‐
gine stop have not been met.
Functional limitations The engine is not switched off automatically in
the following situations:
▷External temperature too low.▷The external temperature is high and auto‐
matic climate control is running.▷The car's interior has not yet been heated
or cooled to the required level.Seite 65DrivingControls65

will not start again automatically if any one of
the following conditions are met.
▷The driver's safety belt is unbuckled and
the driver's door is open.▷The hood was unlocked.
Some indicator lights light up for a varied
length of time.
The engine can only be started via the Start/
Stop button.
Functional limitations
Even if driving off was not intended, the deacti‐
vated engine starts up automatically in the fol‐
lowing situations:
▷Excessive warming of the car's interior
when the cooling function is switched on.▷The steering wheel is turned.▷Double-clutch transmission: Change from
selector lever position D to N, R or D/S.▷M double-clutch transmission: Accelerat‐
ing while simultaneously applying the
brake.▷The vehicle begins rolling.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷Excessive cooling of the car's interior when
the heating is switched on.▷Low brake vacuum pressure; this can oc‐
cur, e.g., if the brake pedal is depressed a
number of times in succession.
Preventing an automatic engine stop with aM double-clutch transmission
The concept To make it possible to drive off very quickly,
such as at an intersection, the automatic en‐
gine stop can be actively prevented.
Preventing an engine stop using the
brake pedal
