sensor CITROEN C4 CACTUS 2020 User Guide

124
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
No alert will be given in the following situations:
-

i

n the presence of non-moving objects
(parked vehicles, barriers, street lamps,
road signs, etc.),
-
on

coming traffic,
-

d

riving on a winding road or a sharp corner,
-
w
hen overtaking or being overtaken by a
very long vehicle (lorry, bus, etc.) that is
detected in the rear blind spot but is also
present in the driver's front field of vision,
-
w
hen overtaking quickly,
-
i
n very heavy traffic: vehicles detected in
front and behind are confused with a lorry or
a stationary object.
Operating fault
The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet sur face
or moving from a dry area to a wet area
can cause false alerts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad weather or in winter, ensure that
the sensors are not covered with mud, ice
or snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on
the front and rear bumpers with adhesive
labels or other objects; they may hamper
the correct operation of the system.
High pressure jet wash
When washing your vehicle, direct the
lance at least 30 cm away from the
sensors.
In the event of a malfunction, you are warned
by the display of a message.
Driving

125
Parking sensors
This function is a manoeuvring aid which
cannot, in any circumstances, replace the
need for vigilance on the part of the driver.
The driver must remain attentive and stay
in control of their vehicle.
They must always check the vehicle's
surroundings before undertaking a
manoeuvre.
During the entire manoeuvre, the driver
must ensure that the space remains clear.
Rear parking sensors
The system is switched on by engaging reverse
g e a r.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.
Audible assistance
The function signals the presence of obstacles
both within the sensor detection zone and in
the vehicle path defined by the orientation of
the steering wheel.
In the example shown, only the obstacles
present in the shaded area will be signalled by
the audible assistance.The information on proximity is given by an
intermittent sound signal, the frequency of which
becomes more rapid as the vehicle approaches
the obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the sound signal becomes
continuous.
The sound emitted by the speaker (right or left)
allows you to identify which side the obstacle is on.
Adjusting the audible signal
Visual assistance
Using sensors located in the bumper, this
function warns of the proximity of obstacles
(e.g. pedestrian, vehicle, tree, barrier) entering
their field of detection. On versions equipped with
CITROËN Connect Radio,
pressing this button opens
the audible signal volume
adjustment window.
6
Driving

126
It supplements the audible assistance,
regardless of the vehicle's path, by displaying
on the screen those whose location represents
the distance between the obstacle and the
vehicle (white: more distant obstacles, orange:
close obstacles, red: very close obstacles).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle is still below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).The sound emitted by the speaker (front or
rear) locates the obstacle in relation to the
vehicle – in the vehicle trajectory, in front
or behind.
Activation/Deactivation
The system is activated or deactivated via the
vehicle configuration menu. F

I
n the Driving/Vehicle
menu
of the touch screen, select the
" Driving functions " tab, then
deactivate/activate " Parking
sensors ".
The system will be deactivated
automatically if a trailer is attached or a
bicycle carrier is fitted on a towbar (vehicle
fitted with a towbar installed in line with
the manufacturer's recommendations).
The parking sensors are deactivated while
the Park Assist system is measuring a
space.
For more information on Park Assist ,
refer to the corresponding section.
Operating limits
- Certain obstacles located in the sensors' blind spots may not be detected or no
longer be detected during the manoeuvre.
-

S
ounds such as those emitted by noisy
vehicles and machinery (e.g. lorries,
pneumatic drills, etc.) may inter fere with the
vehicle's sensors. -

C
ertain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
-
A
ccumulated snow or dead leaves on the
road sur face can inter fere with the vehicle's
sensors.
-
A f
ront or rear impact to the vehicle can
distort the settings of the sensors, which is
not always detected by the system: distance
measurements may be incorrect.
-
T
he tilting of the vehicle if the boot is
very loaded can affect the distance
measurements.
-
T
he sensors may be affected by poor
weather conditions (heavy rain, thick fog,
snowfall, etc.).
Recommendations on care
In bad or wintry weather, ensure that the
sensors are not covered with mud, ice or
snow. When reverse gear is engaged, an
audible signal (long beep) indicates that
the sensors may be dirty.
Driving

127
Operating fault
If a fault occurs when shifting
to reverse, this warning lamp
comes on in the instrument panel,
accompanied by a message and an
audible signal (short beep).
Contact a CITROËN dealer or a qualified
workshop
to have the system checked.
Reversing camera
The reversing camera function may be
supplemented with parking sensors.
The reversing camera cannot, in any
circumstances, replace the need for vigilance
on the part of the driver.
They are represented by lines marked "on
the ground" and do not allow the position
of the vehicle to be determined relative to
tall obstacles (for example: other vehicles,
e t c .) .
Some distortion of the image is normal.
It is normal to have part of the number
plate showing in the bottom of the screen. The green lines 3 represent distances of about
one and two metres beyond the edge of your
vehicle's rear bumper.
The turquoise blue curves 4 represent the
maximum turning circle.
Opening the tailgate causes the display to
disappear.
Clean the reversing camera regularly
using a soft, dry cloth.
High pressure washing
When washing your vehicle, keep the
lance at least 30 cm away from the
camera lens.
High pressure washing
When washing your vehicle, direct the
lance at least 30 cm away from the
sensors.
The reversing camera is activated automatically
when reverse gear is engaged.
The image is displayed on the touch screen. The superimposed representation of guide
lines helps with the manoeuvre.
The blue lines 1 represent the general direction
of the vehicle (the gap represents the width of
your vehicle except for the door mirrors).
The red line 2 represents a distance of about
30 cm beyond the edge of your vehicle's rear
b u m p e r.
Park Assist
This system provides active parking
assistance: it detects a parking space and then
steers in the appropriate direction to park in
this space while the driver controls the driving
direction, engagement of gears, acceleration
and braking.
To assist the driver in monitoring the
correct manoeuvring operation, the system
automatically triggers the display of the rear
view camera and the activation of the parking
sensors.
6
Driving

128
This system is a manoeuvring aid that
cannot under any circumstances replace
the vigilance of the driver.
The driver must remain in control of
their vehicle. They must always check
the surroundings of the vehicle before
undertaking a manoeuvre and ensure that
the space remains clear during the entire
manoeuvre.
The system per forms the measurements of
available parking spaces and calculations of
distances to obstacles using ultrasonic sensors
built in the front and rear bumpers of the
vehicle.
The system assists with the following
manoeuvres:Operation
F When approaching a parking area, reduce the speed of your vehicle to 19 mph
(30 km/h) or less.
Function activation
F Press this button to activate the function.
Activating the function deactivates the
blind spot sensors.
A. Parking when entering a "parallel" parking
space.

coming on.
Driving

129
Parking space search
F You should drive at a distance of between 0.50 m and 1.50 m from the row of parked
vehicles, without ever exceeding 19 mph
(30 km/h), until the system finds an available
space.
The parking space search stops over this limit.
The function automatically deactivates once
the vehicle speed exceeds 31 mph (50 km/h).
For "parallel" parking, the space must at
a minimum be equal to the length of your
vehicle plus 0.60 m.
For "bay" parking, the width of the space
must be equal to the width of your vehicle
plus 0.70 m.
If the parking sensors function has been
deactivated in the Driving/Vehicle menu
of the touch screen, it will be automatically
reactivated when the system is activated. When the system finds an available space,
"
OK " is displayed on the parking view,
accompanied by an audible signal.
Preparing for the manoeuvre
F Move very slowly until the request to stop the vehicle is displayed: " Stop the vehicle"
and the "STOP" panel accompanied by an
audible signal. Once the vehicle has stopped, an instructions
page is displayed on the screen.
F

132
Recommendations on care
- Regularly check that the sensors and cameras are clean.
If necessary, clean the camera lenses with
a soft, dry cloth.
-

I
f using a high-pressure washer, do not
direct the lance less than 30 cm from the
sensors and cameras.
-

I
n bad weather, or during the winter, ensure
that the sensors and cameras are not

Operating faults
When the function is not activated,
the button warning lamp flashing
and an audible signal indicates a
system fault.
If the fault occurs during the use of the system,
the warning lamp goes off.
If the fault in the parking sensors,
indicated by this warning lamp
coming on, occurs during use, it
causes the function to deactivate.
In the event of a fault, have the system checked
by a CITROËN dealer or a qualified workshop. In the event of a fault with the
power steering, this warning lamp
flashes in the instrument panel,
accompanied by a message.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure in all four
tyres, as soon as the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a drop in the pressure of one or more
tyres. The tyre under-inflation detection system
does not replace the need for vigilance on
the part of the driver.
This system still requires you to check the
tyre inflation pressure (including the spare
wheel) every month as well as before a
long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes premature tyre wear, particularly
in adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section.
