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.

200
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
“BRAKE SAFETY” shown on the

multifunction display) warn the dri-
ver and invite him to resume speed
control.
IMPORTANTIf the Radar Cruise
Control is active and the speed of the
vehicle ahead falls below 30 km/h, a
sound signal with message “RADAR
CRUISE CONTROL NOT ACTI-
VATED” on the multifunction display
warn the driver to resume speed con-
trolTherefore, the Radar Cruise Control
does not ensure control when you are
driving in a queue; the driver must
therefore halt the car and start it off
after stopping in a queue, and he
must also switch on the speed control
function every time
IMPORTANT NOTES
CONCERNING THE RADAR
CRUISE CONTROL
When driving with the Radar Cruise
Control on, its regular operation could
be affected by certain situations.
The system operation could be in-
fluenced in the following cases:If the vehicle picked by the car fit-
ted with Radar Cruise Control leaves
the radar sensor detection range, the
system could no longer be able to de-
tect it and therefore it will speed up
the car or pick another vehicle run-
ning ahead (fig. 145).
If a vehicle enters the area between
the car fitted with Radar Cruise Con-
trol and the picked vehicle (fig. 146),
the system could not be able to con-
trol braking and it will therefore warn
the driver to take control of the car.

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.

The driver will be warned by a spe-
cial display message when the system
is deactivated because the lens is
dirty.In this case, clean the sensor protec-
tion lens, shown in fig. 150with a wet
cloth; do not use dry, rough or hard
cloths. Should the dirty lens message
stay on after cleaning, contact a Lan-
cia Dealership.
If the Radar Cruise Con-
trol went off due to exces-
sive lens dirt, when
restarting the car a few km shall
be covered before switching the
system on again in order to let the
system check if previous condi-
tions (causing Radar Cruise Con-
trol turn off) have been removed.The sensor is built into
the front bumper: impacts
can therefore damage it.
IMPORTANTFailure to one of the
safety systems connected to the Radar
Cruise Control (ABS or ESP system)
will cause Radar Cruise Control fail-
ure indication.
The Radar Cruise Control
should be switched on
only when road and traffic
conditions allow the driver to drive
safely, that is, when the road is
straight and the surface is not slip-
pery, when the car is driven on a
freeway or motorway, and when
traffic flows smoothly. Do not use
the device when driving in urban
areas or when traffic is heavy.

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
