Important safety notes G
WARNING
When retracting the AIRCAP, persons could
become caught in the moving mechanism.
There is a risk of injury.
Ensure that persons do not hold onto the
upper frame of the windscreen and do not
touch the AIRCAP wind deflector.
With AIRCAP, four people can travel comfortably with the soft top open. AIRCAP reduces the
draught for the driver and passengers in both
the front and the rear compartment in a vehicle
with the soft top down. 96
Convertible topOpening and closing

AIRCAP has the following components:
R a wind deflector above the windscreen
R a draught stop behind the two rear-seat head
restraints
When AIRCAP has been activated, the draught
stop extends up between the two rear-seat head
restraints. At the same time, the wind deflector
extends out along the front windscreen.
AIRCAP can be activated or deactivated up to
speeds of approximately 160 km/h.
Activating and deactivating AIRCAP X
Turn the key to position 2in the ignition lock.
X To activate: pull switch:.
The draught stop behind the rear-seat headr-
ests and the wind deflector in the roof frame
extend simultaneously. The indicator lamp in
switch :lights up.
X To deactivate: press switch:.
The draught stop behind the rear-seat headr-
ests and the wind deflector in the roof frame
retract simultaneously. The indicator lamp in
switch :goes out.
If you park your vehicle with the soft top down
and remove the key, the wind deflector and the
draught stop retract automatically. When you
restart your engine after having been parked,
the wind deflector and the draught stop extend
again automatically.
AIRCAP cannot be extended or retracted if the
vehicle speed exceeds approximately
160 km/h. Folding draught stop
Important safety notes G
WARNING
If you use the draught stop in darkness or in
other conditions offering poor visibility, your
view to the rear is further impaired. There is a
risk of an accident.
Only use the draught stop when visibility con- ditions are good. G
WARNING
If the draught stop is not fitted correctly, it
could come loose during the journey and
endanger other road users. There is a risk of
an accident and injury.
Fit the draught stop as described.
! Fit or remove the draught stop only when
the soft top is open. You could otherwise
damage the draught stop or the vehicle inte-
rior.
! Observe the backrest position of the front
seats if the draught stop is installed, since the
backrest could collide with the draught stop
here.
! Mercedes-Benz recommends that you only
use draught stops which have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the vehicle.
The folding draught stop protects against wind
when driving with the soft top open. It is secured
above the rear bench seats. For this reason, only the driver and the front passenger can travel in
the vehicle when the folding draught stop is fit-
ted.
The folding draught stop can be fitted or
removed from the driver's side or passenger
side.
You should preferably perform operations
involving the folding draught stop on the side
facing away from traffic, after you have stopped the vehicle, paying attention to road and traffic
conditions. Convertible top
