INITIALISING THE ESP SYSTEM CONTROL UNIT
Whenever the battery is electrically connected again or it is reloaded after being completely flat or after replacing one of
the protection fuses, to restore the correct operation of the ESP system, of the door locking, and of the air conditioning, it
is necessary to perform the initialisation operations contained in the paragraph “If battery is to be disconnected” in the chap-
ter “In an emergency”.

CRUISE CONTROL
(CONSTANT SPEED
REGULATOR)
GENERAL
The electronic cruise control allows
to drive your car at the required
speed without pressing the accelera-
tor pedal. This reduces fatigue when
driving on motorways, especially
during long journeys, because the
set speed is automatically main-
tained.
IMPORTANTThe device can only
be set to speeds exceeding 30 km/h
(40 to 180 km/h for 2.4 JTD 20V
CAE version).The cruise control must
only be used when the
road and traffic condi-
tions allow to keep a constant
speed in total safety for an ade-
quately long time.CONTROLS (fig. 143)
The cruise control is operated by
means of switch A, ring Band but-
ton C(RCL).
Switch Ahas two positions:
– OFFin this position, the device is
off
– ONthis is the normal device
operating position. When the device
is ON, symbol Ülights up on the
multifunction display, together with
message “CRUISE CONTROL ON”.
Ring Bis used to set and maintain
the car speed or to increase or
decrease the set speed.
The device is automatically
switched off when:
– the brake pedal is pressed
– the clutch pedal is pressed
– the gear lever is unintentionally
shifted to N.
In versions with auto-
matic transmission, never
shift the lever to N when
the car is running.

The Radar Cruise Control
must only be used when
the road and traffic condi-
tions allow to keep a constant
speed in total safety for an ade-
quately long time. IMPORTANTThe system can only
be switched on when the car speed
ranges from 30 to 160 km/h and is
automatically switched off by press-
ing the brake pedal. If the car speed
falls below 30 km/h when the system
is on, a buzzer and a visual indication
warn the driver to take control of car
speed again. When the car speed ex-
ceeds 160 km/h after a slight acceler-
ation (“override” mode), a buzzer and
a visual indication will warn the dri-
ver that the system is off.
IMPORTANTThe Radar Cruise
Control cannot be activated when the
driver has switched the ASR system
off.CONTROLS (fig. 144)
The Radar Cruise Control is oper-
ated by three controls, as well as by
the accelerator (to increase speed)
and the brake pedal (to switch the
system off).
Controls are as follows:
– ring Ato switch the system on/off
and to set the distance from the
vehicle ahead, depending on its
speed
– ring B to increase/decrease the
set speed
– button Cto restore the stored
speed.

As long as the car speed exceeds
160 km/h, one of the following indi-
cations will warn the driver that themax. speed limit controlled by the
system is exceeded.
If the road in front of car fitted
with Radar Cruise Control is free.
If a vehicle is detected in front of
the car fitted with Radar Cruise
Control.

199
Ring Ahas four positions:
OFF: system off
x: greatest distance from the vehi-
cle ahead
x: intermediate distance from the
vehicle ahead
x: shortest distance from the vehi-
cle ahead.
The distance between the two vehi-
cles is gradually increased as the
speed is increased, set levels being
equal.
IMPORTANTTurn the ignition
key to STOPor ring Ato OFF, to
delete the stored speed and switch
the system off. To restore system
operation, turn the ring Ato OFF
and repeat the setting operations.When the system is on, that is, ring
Ais in any position other than OFF,
symbol úlights up on the multi-
function display, together with mes-
sage “RADAR CRUISE CONTROL
ON”. The warning light will remain
on until the system is switched off by
turning ring Ato OFF.
Ring Bis used to store the car
speed and keep it constant, or to
increase or decrease the stored
speed.
Turn ring Bto (+) to store the
speed reached or increase the stored
speed.
Turn ring Bto (–) to decrease the
stored speed. Slowing down can also
be obtained, when required, by
braking system automatic operation.
Every time ring Bis turned, the
speed is increased or decreased by
about 1 km/h. By keeping the ring
rotated, the stored speed will change
continuously at intervals of 10
km/h. The new speed reached will
be maintained automatically.
When ring Bis turned, the car’s
actual speed is considered as refer-
ence speed (cruise speed). This
speed can automatically decrease
depending on traffic conditions, and
the system can shift from the speed
control condition to the distance
control condition. The driver is
informed of the system’s operating
condition by the instrument panel
display.
Button C(RCL) allows to reset the
stored speed. In fact, when driving
the car with the system on, the dri-
ver can switch the system off by sim-
ply braking. In this case, the cruise
speed previously set is kept in the
memory and can be enabled again at
any time by pressing button RCL.

201
Deleting the stored speed
The stored speed is automatically
deleted when:
– the engine is stopped
– ring Ais turned to OFF.
When the system is switched off,
any information shown on the
instrument panel display will be
deleted.
Maintaining speed and distance
The system will maintain the
stored speed when no vehicle is
detected along the running path. If,
on the contrary, a vehicle is detected
which runs at a low speed, the sys-
tem will automatically perform the
operations (acceleration, decelera-
tion or slight braking) required to
keep the set distance from the vehi-
cle ahead.The maximum decelera-
tion performed by the sys-
tem automatically is lim-
ited compared to the actual brak-
ing power of the brake system;
therefore, emergency braking can
and must be performed only by
the driver. A buzzer will warn the
driver that the brakes shall be
applied.Detecting a vehicle with the
system active but not switched on
When the system is active (ring A
set to any position other than OFF),
it can detect the presence of a vehi-
cle only after it has been switched on
at least once (by turning ring Bto
(+).
Subsequently, the presence of a
running vehicle will always be indi-
cated, even when the system is off,
until deactivating the system (ring A
set to OFF).
Pressing the brake pedal will
switch the system off, whereas it will
always be possible to accelerate, (e.g
for overtaking), without switching
the system off; the system will auto-
matically bring the car back to the
stored speed when the accelerator
pedal is released (provided that 160
km/h speed has not been exceeded).
The multifunction display gives to
the driver concise information on the
stored speed, the presence of a run-
ning vehicle (if any) and the set dis-
tance.

205
When reaching a steep cat's back
(fig. 153), the picked vehicle could
get out of the radar detection range
(thus missing "picking").The Radar Cruise Control
features proper strategies
to keep adequate comfort
level when travelling on a road
with curves, e.g.: reducing the
cruising speed if required. The
Radar Cruise Control however
cannot detect the road turn; the
driver is therefore the only re-
sponsible for adjusting the car
speed to curves, slip-road or
sharp-curves, not necessarily on
highway sections.
Whenever the picked ve-
hicle gets out of the radar
detection range, the car
will accelerate to return to the set
cruising speed.FAULT INDICATION
System anomalies are signalled by
the lighting of symbol àon the mul-
tifunction display, together with mes-
sage “RADAR CRUISE CONTROL
FAULT”. The fault indication re-
mains on even when system ring Ais
turned to OFF.
Whatever the system's fault, the
Radar Cruise Control is fully switched
off.

PARKING SENSOR
The parking sensor provides dis-
tance information to the driver when
the car moves near obstacles placed
in front of and behind it.
The information on the presence
and distance of obstacles is sent to
the driver by means of sound sig-
nals, the frequency of which
depends on the obstacle distance.
By integrating the direct visual
information with the sound signal
emitted by the system, the driver can
therefore avoid possible collisions.
208
The responsibility for
parking manoeuvres and
other dangerous manoeu-
vres always rests with the driver.
When performing such manoeu-
vres, always make sure that no
persons or animals stand in the
area where the car is to be
parked. The parking assist sys-
tem should be considered as an
aid to the driver; in any case,
greatest attention must be paid
when performing dangerous
manoeuvres, even at low speed.
The system front and rear sensors
are activated automatically when
engaging reverse with the ignition
key at MAR. Disengaging the
reverse gear will turn the rear sen-
sors off; front sensors will stay on
until 15 km/h speed is exceeded to
allow concluding the parking
manoeuvre.Front sensors can be switched on
by pressing button A(fig. 155)
placed on the central console in
front of the gear lever; when the
front sensors are on, warning light
Blights up on the button. To
switch the sensors off, press button
Aagain.
When the sensors are on, the sys-
tem starts sending out sound sig-
nals from the front or rear buzzers
as soon as an obstacle is detected;
the signal frequency increases as
the obstacle gets nearer. When the
obstacle is at a distance of less than
30 cm, a continuous sound is emit-
ted. Depending on the position of
the obstacle (in front or behind),
the sound will be emitted from the
corresponding buzzer (front or
rear). The sound signal will imme-
diately stop if the distance from the
obstacles increases. The tone cycle
remains the same if the distance
measured by the central sensors
does not change; however, if this
condition occurs with side sensors,
the signal will be interrupted after
about 3 seconds, to avoid, for
instance, sending out signals in
case of parking manoeuvres along
walls.

Obstacles placed in side areas are
detected at a distance of less than
0.6 m.
Rear sensors are automatically
switched on by removing the trailer
cable plug.FAULT INDICATIONS
The system control unit checks all
the system components every time
the ignition key is turned to MAR.
Then, the sensors and their respec-
tive electrical connections are con-
stantly monitored during system
operation.
Parking assist system faults are sig-
nalled by the lighting of symbol t
on the multifunction display, togeth-
er with message “PARKING SEN-
SOR FAULT”.
In case of fault signals, stop the
car, shut the engine off, then try to
clean the sensors, making sure that
you are not close to ultrasound-
emitting sources (e.g. truck air
brakes or pneumatic hammers). If
the cause of the operation anomaly
has been remedied, the system fully
resumes its functions and the fault
symbol on the multifunction display
goes out, together with its respective
warning message. Rear sensors are auto-
matically switched off
when the trailer’s electric
cable plug is inserted into the car
tow hitch socket.TOWING A TRAILER
