AIR TEMPERATURE
ADJUSTMENT KNOBS
(fig. 102)
Turning the rings of knobs (1or 6) clock-
wise or counterclockwise, respectively high-
ers or lowers the temperature of the air re-
quired in the left zone (knob 1) or right
zone (knob 6) of the passenger compart-
ment. The temperatures set are shown on
the displays (2) and (5) placed below the
respective knobs.
Separate operation of the temperatures set
is restored automatically using knob (6) is
actuated.
Turning the knob rings clockwise or coun-
terclockwise, until they reach the extreme
selection positions HIor LO, will cause the
maximum heating or cooling functions, re-
spectively, to be switched on:

HI function
(highest heating power - fig. 103)
It is switched on by setting a temperature
of more than 32.5°C on the display, and
can be switched on independently from the
driver’s or passenger’s side, or both of them;
this setting brings the system to the “one-
zone” mode and is shown by both displays.
This functions can be switched on when
you wish to heat the passenger compart-
ment as quickly as possible, by taking the
greatest advantage from the system po-
tential.
The function uses the maximum temper-
ature of the heating fluid, whereas air dis-
tribution to feet and 5
thfan speed.
With the function switched on, however,
all the manual settings can be made.
To switch the function off, you only need
to turn the ring of a knob (1) or (6) of the
temperature set to a value lower than
32.5°C; the opposite display will show
32.5°C.By pressing button (14)

LO function
(highest cooling power - fig. 104)
It is switched on by setting a temperature
lower than 16.5°C on the display; this set-
ting is shown by both displays.
This function can be switched on when you
wish to cool the passenger compartment as
quickly as possible, by taking the greatest
advantage from the system potential.
The function cuts off air heating, switches
on both internal air recirculation (to prevent
hot air from entering the compartment) and
the climate control compressor, brings air
distribution to E
and 5
thfan speed.
With the function switched on, however,
all the manual settings can be made.
To switch the function off, you only need
to turn the ring of a knob (1) or (6) of the
temperature set to a value greater than
16.5°C; the opposite display will show
16.5°C.

FAN SPEED ADJUSTMENT
KNOB
(fig. 106-107)
Turning the ring of knob (3), clockwise
or counterclockwise will cause the fan speed
- and, therefore, the amount of air flowing
into the passenger compartment - to in-
crease or decrease, respectively; the 16
speeds that can be selected are displayed
by a bar (every 3 clicks), up to a maximum
of 6 illuminated bars:
– max. fan speed = all bars lit;
– min. fan speed = one bar lit.
The fan can be cut off (all bars off) only
if the climate control compressor has been
switched off by pressing button (12)
√
.
To resume automatic fan speed control af-
ter a manual setting has been made, press
button (14)
AUTO
. By fully turning the ring
of knob (3) counterclockwise, the system
will be turned off, with the following situa-
tion: display (2) OFF; display (5) OFF; cen-
tral display (4) OFF and left-hand led avail-
able on internal air recirculation button (7)

When the climate control compressor is off,
it is not possible to admit air to the pas-
senger compartment with a temperature be-
low the outside temperature; in this case,
the value flashes on the display concerning
the temperature that cannot be reached
and the left led on button (14

The switching off of the climate control
compressor remains in storage even when
the engine has been stopped. To resume au-
tomatic control for switching on the climate

ing the air; it is advisable to keep
this function always on, to prevent
window misting problems.

Inspect the care carefully to make sure that
there are no fuel leaks, for instance in the
engine compartment, under the vehicle or
near the tank area.
If no leaks are found and the vehicle can
be restarted again, press button (A) to ac-
tivate the fuel supply system.
After a collision, remember to turn the ig-
nition key to STOP so as not to run the bat-
tery down.
INERTIAL FUEL CUT-OFF
SWITCH
(fig. 119)
This is an automatic safety switch which is
triggered in the event of crash to interrupt
the flow of fuel.
The intervention of the inertial switch is in-
dicated by a message + symbol on the In-
focenter display (see “Infocenter Display”
in this chapter) and by the door unlocking.

WARNING

Failures of Selespeed gearbox are signalled
to the driver through a warning light (B-fig.
126) accompanied by an acoustic signal. The gearbox can work in two operating
modes:
– the first is semiautomatic(then called
MANUAL), in which the driver directly re-
quests gearshifting through the lever on the
centre console or pressing the buttons at the
steering wheel;
– the second is automatic, calledCITY
(mode selectable with the specific button
B-fig. 124, the CITYsign appears on the
display fig. 126fitted on rev-counter), in
which the system decides directly when to
shift gear.With the gearbox in the CITYmode it is
still possible to carry out manual gearshift-
ing, both using the gear lever and the steer-
ing wheel controls. The gearbox remains in
the CITYmode.
The gear engaged (fig. 126) is always
signalled on the display regardless of the se-
lected mode.
N= neutral;
1= first gear;
2 = second gear;
3= third gear;
4= fourth gear;
5= fifth gear;
R= reverse.
