READY TO START
MANUAL MODE
IMPORTANT For correct use of the sys-
tem, it is advisable to use your right foot
only to operate the pedal.
❒Press the brake pedal.
❒Start the engine.
❒Push the gear lever towards + (shift up)
fig. 1to engage first gear (if starting
from Nor Rsimply move the lever to
the central position) or R fig. 2to en-
gage reverse.
❒Release the brake pedal and press the
accelerator pedal.
❒When driving, push the gear lever to-
wards (+)fig. 1to engage a higher gear
or towards (–)fig. 1to engage a low-
er gear.
COMFORT-MATIC
GEARBOX
Your vehicle is equipped with an elec-
tronically controlled manual gearbox
known as the “COMFORT-MATIC” that
is able to operate in two modes: MAN-
UALand AUTO.
The gearbox consists of a conventional
manual transmission equipped with a lever
A-fig. 1, to which has been added an elec-
tronically-controlled hydraulic device that
controls the clutch and gear shifts auto-
matically.

AUTOMATIC MODE
IMPORTANT For correct use of the sys-
tem, it is advisable to use your right foot
only to operate the pedal.
❒Press the brake pedal.
❒Start the engine.
❒Push the gear lever to A/M fig. 3, to
engage automatic mode +(higher gear)
fig. 1to engage the first gear, if start-
ing from Nor Rmove the lever to cen-
tral position R fig. 2to engage reverse.
❒Release the brake pedal and press the
accelerator pedal.
OPERATING MODE
The gearbox can operate in two operat-
ing modes:
❒the first is manual (MANUAL), where
the driver decides directly when to shift
gear;
❒the second fully automatic (AUTO),
where the system decides when to shift
gear. This mode allows you to use the
UPfunction (steep road function),
which allows you to shift gears at high-
er speeds to allow you to drive up very
steep roads easily with any load. To en-
gage this function, press the UPbut-
ton - fig. 4between the controls on the
dashboard. Select the gear and the op-
erating mode MANUALor AUTO)
by operating the control lever at any
speed.

CONTROL LEVER
Control lever A-fig. 1, on the central
tunnel is a floating multistable lever, i.e. it
can take up three stable positions and
three unstable positions.
The three stable positions correspond to
neutral N-fig. 2, reverse R-fig. 2and the
central position between the unstable po-
sitions (–) and (+)fig. 1.
The unstable positions, i.e. positions left
by the lever as soon as it is released, are
upshift request (+), downshift request (–)
and automatic mode request (A/M)
fig. 3.

The system is returned to manual mode
by returning the lever to A/Mposition.
With the vehicle at a standstill and the key
out, the lever may be moved with/without
the brake pedal pressed. The system does
not carry out any action after the lever has
been shifted and remains in the gear
stored before the key was removed.
IMPORTANT With the engine running, a
buzzer sounds to indicate errors between
the lever position and the gear effectively
engaged until the inconsistency is resolved.MANUAL OPERATION
(MANUAL)
In this operating mode, the driver is re-
sponsible for choosing the best gear ra-
tio to engage, depending on vehicle ser-
vice conditions.
Proceed as follows to shift gear:
❒shift the lever to (+) position fig. 1to
engage a higher gear;
or
❒shift the lever to (–) position fig. 1to
engage a lower gear.
The accelerator pedal need not be re-
leased during the gear change.
The system will not allow the gear change
if the gear shift request could impair cor-
rect operation of the engine and gearbox.
In this case, the system will notify the dri-
ver that it is not possible to change gear
by displaying a dedicated message on the
reconfigurable multifunction display (see
“Warning lights and messages” paragraph),
accompanied by a buzzer.
The system will shift down through the
gears automatically when the engine is
idling (e.g. during deceleration).Avoid keeping your hand on
the lever when you are not re-
questing a gear shift or an
Auto/Manual mode change.
AUTOMATIC OPERATION
(AUTO)
to engage/release automatic mode (AU-
TO) press the lever to A/M positionfig.
3; activation is indicated by the message
AUTO fig. 5and the gear engaged ap-
pearing on the reconfigurable multifunc-
tion display.

Avoid keeping your hand on
the lever when you are not re-
questing a gear shift or an
Auto/Manual mode change.Automatic operation
(AUTO with UP function engaged)
The UPcan only be activated with auto-
matic mode engaged.
The UPfunction is turned on by press-
ing the UP button fig. 4 located between
the controls in the dashboard. After this
function is activated the (green) warning
light
0in the instrument panel comes
on together with a confirmation message
in the reconfigurable multifunction display
(see next paragraph).
With the UPactive, the system will select
the most appropriate gear on the basis of
vehicle speed, engine rpm and pressure on
the accelerator pedal, with the aim of
overcoming steep gradients in the easiest,
most comfortable manner.
Where necessary (e.g. overtaking), the
system will react to the accelerator be-
ing pressed to the floor by shifting down
through one or more gears in order to de-
liver the power and torque required to
give the vehicle the acceleration required
by the driver (all this takes place in auto-
matic mode, irrespective of whether the
UPfunction is on or off).
In AUTO mode, the system will shift
gears on the basis of vehicle speed, engine
rpm and the pressure applied to the ac-
celerator pedal. A gear shift may be re-
quested by operating the gear lever, but
without necessarily disengaging this mode:
this function, known as ‘gear suggestion’,
suspends automatic mode for the time re-
quired to select the ratio requested by the
driver.INFORMATION ON DISPLAY
When the ignition key is turned to MAR,
after one second, the reconfigurable mul-
tifunction display shows the gear engaged
and the last mode used (AUTOor
MANUAL):
N= neutral;
1= first gear;
2= second gear;
3= third gear;
4= fourth gear;
5= fifth gear;
6= sixth gear;
R= reverse.

When the UPfunction is activated the
(green) warning light
0in the instru-
ment panel comes on together with a con-
firmation message in the reconfigurable
multifunction display.
IMPORTANT If the display does not show
the gear engaged after 10 seconds with the
ignition key on MAR, turn the ignition to
STOP, wait for the display to turn off and
then repeat the manoeuvre. If the prob-
lem persists, contact the Fiat Dealer-
ship.ENGINE STARTING
The system permits engine start-up with
a gear engaged and also with the gearbox
in neutral (N); the brake pedal must al-
ways be pressed with the gear engaged.
It is advisable to place the gear lever in
neutral (N) before starting the engine.
After start-up:
❒the gearbox automatically engages neu-
tral (N)
❒the lever remains in the same position
as the last time the engine was turned
off
❒the reconfigurable multifunction display
shows the message (N) and an acoustic
signal indicates any inconsistency be-
tween lever position and the gear en-
gaged
❒the gears that may be engaged are 1st,
2ndor reverse (R), with the brake ped-
al pressed.IMPORTANT If start-up is requested with
the gearbox is a position other than Nand
without the brake pedal pressed, the re-
configurable multifunction display shows a
dedicated message see “Warning lights
and messages”). In this case, repeat the
start-up manoeuvre, pressing the brake
pedal.
IMPORTANT If start-up is requested with
the gearbox faulty, run the “Delayed start-
up” procedure (see also associated mes-
sages): hold the key on AVVposition for
at least 7 seconds with the brake depressed
and the engine will start. The system will
remain in recovery mode (maximum speed
permitted: 3
rd, Auto mode not available).
If the engine does not start, contact a Fiat
dealership.
IMPORTANT When the driver’s door is
opened, the system activates the auto-
matic part to prepare it for subsequent en-
gine start-up.
If the engine does not start
with the gear engaged, a po-
tentially hazardous situation
because the gearbox has au-
tomatically shifted to neutral is indi-
cated by a buzzer.
