Checking vent frame

– Check the air ducts to both vent frames -A- in the luggage
compartment for blockage (left and right).
♦ The sealing lips -B- in the vent frame -A- must move freely and
close automatically.
♦ Clogged ducts or gummed sealing lips could cause the win‐
dows to mist up.
Note
This Fig. shows the vent frame with the rear bumper removed.
♦
One vent frame each is installed on the left and right for forced
♦
air extraction.
The sealing lips -B- only close properly if the vent frame -A-
♦
has been installed correctly (smaller radius -C- at top).
To ensure proper functioning of the passenger compartment
♦
ventilation, the vent openings -C- in the left and right luggage
compartment lining are never to be sealed off.
The air from the passenger compartment flows via vent slits in
♦
the rear shelf and through slits incorporated into the upper lin‐
ing -B- into the luggage compartment.
