Folding(fig. 31)
– In the event of need (for example when
the mirror causes difficulty in narrow spaces)
it is possible to fold the mirror moving it from
position (A) to position (B).Defrosting/demisting(fig. 32)
The electric mirrors are fitted with heat-
ing coils which come into operation with
rearscreen heating pressing the button (A)
thereby defrosting and/or demisting the mir-
rors.
IMPORTANTThe function is timed and
automatically switched off after a few min-
utes.

PRE-TENSIONING DEVICES
To increase the efficiency of the front seat
belts,Alfa 147 GTAis fitted with pre-
tensioning 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.IMPORTANTThe 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 Al-
fa 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.

wise or counter-clockwise, respectively high-
ers or lowers the temperature of the air re-
quired respectively in the left zone (knob 2)
or right zone (knob 6) of the passenger
compartment. The temperatures set are
shown on the displays (1) and (5) above
the knobs.
Separate operation of the temperatures set
is restored automatically using knob (6).

HI function
(highest heating power - fig. 79)
This is turned on setting on the display a
temperature above 32.5°C, and can be ac-
tivated independently from the driver’s or
passenger’s side or both; this setting brings
the system to the “monozone” mode and
is shown on both displays.
This function can be engaged when re-
quiring to heat the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
This function uses the maximum temper-
ature of the coolant fluid, while air distribu-
tion and fan speed are controlled according
to the system settings.
This function is unadvisable with
the engine cold to prevent admit-
ting air that is not warm enough to
the passenger compartment.
All manual settings are possible with this
function on.
To switch the system off, simply turn the
ring of knob (2) or (6) of the temperature
set to a value below 32.5°C; the opposite
display will show 32.5°C.

temperature below 16.5°C; this setting is
shown on both displays.
This function can be engaged when re-
quiring to cool the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
The function cuts off air heating, engages
inside air re-circulation (to prevent admitting
hot air to the passenger compartment) and
the climate control compressor, takes air dis-
tribution to
REand the fan speed as set by
the system.
All manual settings are possible with this
function on.
To switch the function off, simply turn the
ring of knob (2) or (6) of the temperature
set on a value above 16.5°C; the opposite
display will show 16.5°C.
Pressing key (13)

ADJUSTMENT KNOB
(fig. 82-83)
Turning the ring of knob (4), clockwise
or counter-clockwise, increases or decreas-
es the speed of the fan, thus the amount
of air admitted to the passenger compart-
ment; the 16 selectable speeds are shown
on a bar (in steps of 3) up to a maximum
of 6 bars lit:
- maximum fan speed = all bars lit;
- minimum fan speed = one bar lit.
The fan can be cut off (all bars off) only
if the climate control compressor has been
switched off pressing button (14)
√. To
restore automatic fan speed control, after a
manual adjustment, press button (13)
