Manual Release of Fuel Filler Flap

If the central locking system does not
release the fuel filler flap autom ati­
cally, pull back the knob on the vacu­
um element on the right side of the
trunk while opening the filler flap.
Windshield Wipers
To release frozen windshield w iper
blades or to replace worn blades, the
windshield w iper arms can be pulled
out of their recess by hand. Sufficient
force m ust be applied to overcome
spring resistance. Be careful not to
tear rubber blades w hich are frozen
to the glass, as this will reduce the
effectiveness of the wipers.
To ensure operation of the windshield
wiper even when it is snowing heavily,
an overload protection has been
installed. It becom es effective if a cer­
tain wiping resistance is exceeded as
a result of snow accumulation. The
w indshield w iper arm will then no lon­
ger return com pletely to its initial posi­
tion, although the windshield w iper
m otor continues to run a full cycle. If
this condition is encountered, the
accumulated snow should be man­
ually removed when it is safe.
