Turn ring Bto position (+) to set
the speed reached or to increase the
stored speed.
Turn ring Bto position (–) to
decrease the stored speed.
The speed will be increased or
decreased by approximately 1 km/h
each time ring Bis operated. Hold
the ring turned to set the speed con-
tinuously. The new set speed will be
automatically kept.
Button C(RCL) allows to reset the
stored speed.
IMPORTANTTurn the ignition
key to STOPor switch Ato OFFto
delete the stored speed and switch
the system off.Storing the speed
Move switch Ato ONand take the
car to the required speed normally.
Turn ring Bto (+) for at least three
seconds and release it. The car speed
will be stored and you can now
release your foot from the accelera-
tor.
The car will continue at the con-
stant speed until one of the following
events occur:
– the brake pedal is pressed
– the clutch pedal is pressed
– the automatic gear lever is unin-
tentionally shifted to N.
IMPORTANTIf required (e.g. for
overtaking) you can accelerate sim-
ply by pressing the accelerator. The
car will return to the previously set
speed when the accelerator pedal is
released.Resetting the stored speed
To reset the stored speed after
switching the device off, e.g. by
pressing the brake or the clutch ped-
als:
– accelerate progressively to reach
a speed which is close to the previ-
ously set speed
– engage the gear which was
engaged when the speed was set (4
th,
5thor 6th gear)
– press button C (RCL).
Increasing the stored speed
The stored speed can be increased
in two ways:
– by pressing the accelerator pedal
and storing the new speed (turning
ring Bfor longer than three seconds)

196
or
– by momentarily turning ring Bto
(+): each turn of the ring will corre-
spond to a small speed increase
(approximately 1 km/h), while a
continuous pressure will correspond
to a continuous speed increase.
Release ring B: the new speed will
automatically be stored.
Reducing the stored speed
The stored speed can be decreased
in two ways:
– by switching the device off (e.g.
by pressing the brake pedal) and
then storing the new speed (turning
ring Bto (+) for longer than three
seconds)
or
– by turning ring Bto (–) until the
new speed is reached. The new speed
will automatically be stored.Deleting the stored speed
The stored speed is automatically
deleted when:
– the engine is stopped
or
– switch Ais turned to OFF.
When driving with the
cruise control, do not
shift the gear lever to neu-
tral. You should only switch the
cruise control on when the traffic
and road conditions allow this in
complete safety, i.e. straight and
dry roads, motorways, fast mov-
ing traffic and smooth road sur-
face. Do not use the device in
cities or in heavy traffic.The cruise control can
be switched on at speeds
higher than 30 km/h (40
to 180 km/h for 2.4 JTD 20V CAE
version). The device can only be
switched on in 4th, 5th or 6th
gear, according to car speed. In
versions with automatic trans-
mission, the device must only be
switched on with the gear lever at
D during automatic operation
without shifting the lever subse-
quently, or with the 3
rdor 4thgear
engaged during manual sequen-
tial operation.
When travelling down-hill the
speed may increase with respect
to the stored value according to
the change in engine load.

RADAR CRUISE
CONTROL (RCC)
GENERAL
The Radar Cruise Control (RCC)
assists the driver by monitoring both
the cruise speed and the distance of
the vehicle ahead along the running
path: it allows to drive your car at
the required speed, without pressing
the accelerator pedal.
The system reduces fatigue when
driving on motorways, especially
during long journeys, since the
stored speed is maintained automat-
ically; moreover, the system con-
tributes to keeping a safe distance
from the vehicle ahead. Constant
speed driving also allows to cut
down fuel consumption and makes
traffic smoother.The Radar Cruise
Control is not an “auto-
matic pilot” but a driver-
assisting device; therefore, only
the driver is responsible for
his/her driving behaviour and
must comply with the highway
code regulations in force, as well
as with any other provision con-
cerning road traffic.
This system detects just
moving vehicles and
ignores whatever immo-
bile object.The Radar Cruise
Control is not an anti-col-
lision device: it cannot
detect the presence of obstacles
on the road or stop the car in case
of danger. Any action performed
by the driver on the brake or
accelerator pedals takes priority
over the cruise control system; for
this reason, the responsibility for
road safety always rests with the
driver.
The system is electronically con-
trolled, self-contained and, there-
fore, does not require communica-
tion with other vehicles or the pres-
ence of similar systems on the other
vehicles.
The system cannot actu-
ate emergency braking:
the maximum decelera-
tion automatically performed by
the system is limited compared to
the actual braking power of the
brake system; therefore, emer-
gency braking can and must be
performed only by the driver.

198
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.

Storing the speed
Move ring Ato any position other
than OFFand take the car to the
required speed.
Turn ring Bto (+), then release it.
The car speed will be stored and
shown on the instrument panel dis-
play; now, the accelerator pedal can
be released.
The car will continue at the con-
stant speed until one of the following
events occur:
– the brake pedal is pressed
– presence of a vehicle running
ahead more slowly along the run-
ning path, in the same running
direction.
IMPORTANTIf required (e.g. for
overtaking) you can accelerate sim-
ply by pressing the accelerator. The
car will return to the previously set
speed when the accelerator pedal is
released. If 160 km/h speed is
exceeded, restore the stored speed by
pressing C(RCL).Resetting the stored speed
If the system has been switched off
by pressing the brake pedal, the
stored speed can be resumed by
pressing button C(RCL).
Increasing the stored speed
The stored speed can be increased
in two ways:
– by pressing the accelerator and
storing the new speed (turning ring
Bto (+)
or
– by temporarily turning ring Bto
(+): each turn of the ring will corre-
spond to a 10 km/h speed increase,
while a continuous pressure will cor-
respond to a continuous speed
increase at intervals of 10 km/h.
Release ring B: the new speed will
automatically be stored.
The new set speed will be shown on
the display in place of the previous
one. Reducing the stored speed
The stored speed can be decreased
in two ways:
– by switching the device off (e.g.
by pressing the brake pedal) and
then storing the new speed (turning
ring Bto (+)
or
– by turning ring Bto (-) until the
new speed is reached. The new speed
will automatically be stored.
The new set speed will be shown on
the display in place of the previous
one.

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.

202
Detecting a vehicle with the
system switched on
When the system is switched on by
turning ring Bto (+),any vehicle run-
ning in front of the car (within 130
metres) and along the running path
will be signalled to the driver on the
instrument panel display, with the fol-
lowing icon:
set distancex
set distancexset distance
x
This icons indicate the engagement
of speed and distance control with de-
tection of a running vehicle along the
running path, “picked” by the system.
The three different icons indicate the
three distance levels the driver can se-
lect.
When the external temperature is
less than 3 °C, the system will auto-
matically be set to maintain a greater
distance from the vehicle ahead, re-
gardless of the distance set.
If the system is temporarily switched
off by pressing the accelerator pedal,
the stored speed will flash on the in-
strument panel and the distance con-
trol icon will disappear (if shown on
the instrument panel display). Theicon (if any) indicating the vehicle de-
tected on the traffic lane will, on the
contrary, remain visible.
With system active and car speed ex-
ceeding 80 km/h, switching the left
direction indicators on to signal over-
taking will cause the distance from
the vehicle ahead (already “picked”)
to be automatically decreased in or-
der to facilitate the manoeuvre. If the
driver does not overtake within a few
seconds, the car will return to the set
distance.
If the Radar Cruise Control is active
and the braking power enabled for
the function does not ensure the
maintenance of the set distance from
the vehicle ahead, a sound and visual
signal (together with message

Do not use the Radar
Cruise Control under poor
visibility conditions (e.g.:
fog, heavy rain, snow, etc.), since
the system performance could be
badly affected.
IMPORTANTAs you approach a
bend, it may be necessary to reduce
the stored speed or switch the system
off by pressing the brake pedal.
The brake pedal is oper-
ated by the Radar Cruise
Control system: do not po-
sition your foot under the brake
pedal.IMPORTANTThe Radar Cruise
Control can only be switched on when
the car speed ranges from 30 and 160
km/h. The Radar Cruise Control is
automatically switched off when any
of the ABS, ASR, MSR and ESP sys-
tems comes into operation. Moreover,
it is switched off when engaging re-
verse gear, neutral or the electronic
parking brake (EPB).
IMPORTANTThe Radar Cruise
Control cannot be activated when the
driver has switched the ASR system
off.In the device is faulty or
does not work, turn ring A
to OFF and contact a Lan-
cia Dealership
IMPORTANTRing Acan be con-
stantly left in a position other than
OFFwithout damaging the Radar
Cruise Control. The device should
however be switched off when not in
use by turning ring Ato OFFto pre-
vent storing speeds accidentally.
