Lancia THESIS. Service Manual - part 13

204

If a vehicle enters the same running

path as that of the car fitted with
Radar Cruise Control and sets too
close to it (fig. 147), the system could
not be able to detect it.

If two heavy-duty vehicles (e.g.:

trucks) overtake at low speed (fig.
148), the car fitted with Radar Cruise
Control could temporarily detect the
road as free.

When entering or leaving a curve

(fig. 149), a vehicle running ahead
could temporarily get out of the radar
detection range, or another vehicle
running in the adjacent lane could be
detected.

When cornering (average-sharp

curve), any vehicle picked by the
Radar Cruise Control could get out of
the radar detection range (fig. 150)
thus missing "picking".

At a slip-road (fig. 151-152), if fol-

lowing a vehicle running at a speed
lower than that set on the car fitted
with Radar Cruise Control, when
changing lane the path will result free
and therefore the system will acceler-
ate to restore the set speed.

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 à on the mul-
tifunction display, together with mes-
sage “RADAR CRUISE CONTROL
FAULT”. The fault indication re-
mains on even when system ring A is
turned to OFF.

Whatever the system's fault, the

Radar Cruise Control is fully switched
off.

206

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. 150 with 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.

IMPORTANT Failure 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.

fig. 154

L0A0330b

207

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.

IMPORTANT As 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.

IMPORTANT The 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).

IMPORTANT The 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

IMPORTANT Ring A can be con-

stantly left in a position other than
OFF without damaging the Radar
Cruise Control. The device should
however be switched off when not in
use by turning ring A to OFF to pre-
vent storing speeds accidentally.

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
B lights up on the button. To
switch the sensors off, press button
A again.

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.

SENSORS

The system detecting the distance

from obstacles uses 4 sensors housed
in the front bumper (fig. 156) and 4
sensors housed in the rear bumper
(fig. 157).

To ensure proper opera-

tion of the parking assist
system, it is essential that

the sensors placed on bumpers
are always free from mud, dirt,
snow or ice. 

When cleaning the sen-

sors, take the greatest
care not to scratch or

damage them; to this regard, do
not use dry, rough or hard cloths.
Sensors must be washed with
clean water, to which car sham-
poo can be added, if necessary. In
car-wash stations that use high-
pressure or steam-jet hydraulic
cleaning machines, clean the sen-
sors fast by keeping the nozzle at
a distance of at least 10 cm.

When the bumper needs

re-painting or the sensor
area needs touching-up

with paint, contact a Lancia
Dealership only. Incorrect appli-
cation of paint could adversely
affect the parking sensor opera-
tion.

Sensor operating range

The sensors allow the system to

monitor the car’s front and rear
parts.

Their position covers the middle

and side areas of the car’s front and
back (fig. 158).

Obstacles placed in the middle area

are detected at a distance of less
than approx. 0.9 m (front) and 1.50
m (rear).

211

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

212

If, on the contrary, the warning

lamp remains on, go to a Lancia
Dealership to have the system
checked even if the system keeps on
working. In fact, if the fault detected
by the control unit does not affect
the operation of the system, the lat-
ter keeps on working and the mal-
function is stored in the memory so
as to be detected by the Lancia
Dealership during a subsequent
check.

GENERAL NOTES 

When parking your car, always pay

the greatest attention to the obsta-
cles that could be situated above or
below the sensors. In fact, objects
situated at close range in the car’s
front or rear parts could, under cer-
tain circumstances, not be detected
by the system and, therefore, dam-
age your car or be damaged them-
selves.

Moreover, signals sent by the sen-

sors can be altered by damaged sen-
sors, by accumulation of dirt, snow
or ice on the sensors, or by ultra-
sound systems (e.g. truck air brakes
or pneumatic hammers) being oper-
ated nearby.
