Aero-acoustic deflector
An aero-acoustic deflector is available to
improve the acoustic comfort of occupants of
the vehicle in certain driving conditions (high
speed), by reducing the turbulence in the
passenger compartment resulting from the
displacement of air.
On opening the roof, the aero-acoustic
deflector may be deployed if it is not secured.
On closing the roof, the deflector folds away
automatically.
With the roof open, this deflector can be
folded away manually and secured at its
centre : press vertically down on the cross
member near the paddle at the top of the
deflector and clip this paddle in the cut-out.
To release and deploy the deflector
manually, press vertically down on the
cross member near the paddle to unclip it
from the cut-out and pull it gently towards
you.
Operating the roof when
driving
The roof opening and closing control
operates up to about 70 mph (120 km/h).
Above this speed, a message in the
screen informs you that operation of the
roof is not possible (speed too high).
If a roof operation is started before the vehicle's
speed is above about 70 mph (120 km/h),
exceeding this speed limitation leads to the
following situations, depending on the type of
roof operation in progress:
- an operation in progress in zone A is
