PRE-TENSIONING DEVICESTo increase the efficiency of the front seat
belts, Alfa 156 is fitted with pre-tension-
ing devices.
These devices “feel” that the car is being
subject to a violent impact by way of a sen-
sor rewind the seat belts a few centimetres.
In this way they ensure that the seat belt
adheres to the wearer before the restraining
action begins.
The seat belt locks to indicate that the de-
vice has intervened; the seat belt cannot be
drawn back up even when guiding it man-
ually.
WARNINGThe pretensioner will give
maximum protection when the seat belt ad-
heres snugly to wearer’s chest and hips.
Front seat pretensioners activate only if
front seat belts are properly fitted into buck-
les. A small amount of smoke may be pro-
duced. This smoke is in no way toxic and
presents no fire hazard.
The emergency tensioning retractor needs
no maintenance or lubrication. Any modifi-
cation to its original features will nullify the
retractor’s effectiveness. If, due to unusual
natural events (floods, high waves, etc.),
the device has been affected by water and
mud, it must be replaced.Operations involving
banging, vibrations or
heating (above 100°C for
a maximum of 6 hours) in the area
of the pretensioners may damage
or trigger off the device. Vibrations
from rough road surfaces or acci-
dental jolting caused by mounting
pavements etc. do not have any ef-
fect on the pretensioner. If, how-
ever, you need assistance, go to
Alfa Romeo Authorized Services.
The pretensioner can only
be used once. After a col-
lision that has triggered it, have it
replaced at Alfa Romeo Authorized
Service. The validity of the device
is written on the plate located on
the front left door near the lock.
Contact Alfa Romeo Authorized
Services to have pretensioner re-
placed as this date approaches.
WARNING
After adjustment, always
check that the slider (B) is
anchored in one of the positions
provided. To do this, with the but-
ton (A-fig. 50) or (A-fig. 51) re-
leased, exert a further pressure to
allow the anchor device to catch if
release did not take place at one of
the preset positions.
WARNING
Make the height adjust-
ment when the car is sta-
tionary.

to turn the inside air
re-circulation function on.
When this function is on the relevant but-
ton led will come on.
It is advisable to turn on the inside air re-
circulation function in queues or tunnels to
avoid admitting polluted air from outside.
The prolonged use of this function should
however be avoided, especially with several
persons on board, to avoid the possibility of
the windows misting inside.WARNINGThe inside air re-circulation
function makes it possible to reach the re-
quired "heating" or "cooling" conditions
faster.
It is however inadvisable to use it on
rainy/cold days as it would considerably in-
crease the possibility of the windows mist-
ing inside, especially if the climate control
system is off.

– turn knob (1) as far as it will go coun-
terclockwise (blue led next to TEMPlit);
