2021 CITROEN C4 CACTUS Owners Manual

119
If the camera has confirmed
the presence of a vehicle or a
pedestrian, this warning lamp
flashes once the function is acting
on the vehicle's brakes.
Important: if operation of the
automatic emergency braking is
triggered, you should take back
control of your vehicle and brake
with the pedal to add to or finish the
automatic braking action.
The driver can take back control of the vehicle
at any time by sharply turning the steering
wheel and/or pressing the accelerator pedal.
The point at which braking is triggered
may be adjusted depending on the driving
actions of the driver, such as movement
of the steering wheel or actions on the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained for 1
to 2 seconds. With a manual gearbox, in the event of
automatic emergency braking until the
vehicle comes to a complete stop, the
engine may stall.
With an automatic or electronic gearbox,
in the event of automatic emergency
braking until the vehicle comes to a
complete stop, keep the brake pedal
pressed down to prevent the vehicle from
starting off again.
Specific conditions for operation
The vehicle's speed must be between 3 mph
and 53 mph (5 km/h and 85 km/h) when a
moving vehicle is detected.
The vehicle's speed must not exceed 50 mph
(80 km/h) when a stopped vehicle is detected.
The vehicle's speed must not exceed 37 mph
(60 km/h) when a pedestrian is detected.
The ESC system must not be faulty.
The ASR system must not be deactivated.
All passenger seat belts must be fastened.
Sporty driving or driving on winding roads may
impede the function.
After an impact, the function automatically
stops operating. Consult a CITROËN
dealer or a qualified workshop to have the
system checked.
Deactivation/Activation
By default, the system is automatically
activated at every engine start-up. Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a message.

Malfunction
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
The system is automatically deactivated
after the use of the "space-saver" type
spare wheel is detected, or if a fault with
the side brake lamps is detected.Fatigue detection system
Take a break as soon as you feel tired or at
least every two hours.
The function has the "Driving time warning"
combined with the "Driver inattention alert".The system cannot in any circumstances
replace the need for vigilance on the part
of the driver.
Do not take the wheel if you are tired.
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
" Vehicle settings " tab then
" Safety " and activate/deactivate
" Fatigue detection ".
Driving time warning
The system triggers an alert once it
detects that the driver has not taken
a break after two hours of driving at
a speed above 40 mph (65 km/h). This alert is issued via the display of a
message encouraging you to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the
alert is repeated hourly until the vehicle is
stopped.
In the event of a fault with the
system, you are alerted by the
illumination of this warning lamp,
accompanied by the display of a
message and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked. The system resets itself if one of the following
conditions is met:
-

e
ngine running, the vehicle has been
stationary for more than fifteen minutes,
-
t
he ignition has been switched off for a few
minutes,
-
t
he driver's seat belt is unfastened and their
door is open.
As soon as the vehicle's speed drops
below 40 mph (65 km/h), the system goes
into standby.
Driving time monitoring resumes when the
vehicle travels at above 40 mph (65 km/h).
Driving

121
Driver inattention alert
Using a camera placed at the top
of the windscreen, the system
assesses the driver's level of
vigilance by identifying variations
in trajectory compared to the lane
markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65 km/h)).
When the system interprets the behaviour of
the vehicle as indicating a certain fatigue or
inattention threshold on the part of the driver, it
triggers the first level of alert. After three first level alerts, the system triggers
a new alert with the message "
Take a break!",
accompanied by a more pronounced audible
signal.
In certain driving conditions (poor road
sur face or strong winds), the system may
give alerts independent of the driver's
level of vigilance. The following situations may interfere with
the operation of the system or prevent it
working:
-

p
oor visibility (inadequate lighting of
the roadway, falling snow, heavy rain,
dense fog, etc.),
-
d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
-
w
indscreen area located in front of the
camera: dirty, misted up, frost-covered,
snow-covered, damaged or covered by
a s t i c ke r,
- l ane markings absent, worn, hidden
(snow, mud) or multiple (roadworks,
e t c .),
-

c
lose to the vehicle ahead (lane
markings not detected),
-

r
oads that are narrow, winding, etc.
The driver is then alerted by the message
"
Ta k e c a r e ! ", accompanied by an audible
signal.

Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
Lane Departure Warning
System
System which, using a camera which
recognises solid or broken lines, detects the
involuntary crossing of longitudinal traffic lane
markings on the ground.
The camera analyses the image then, if the
driver's attention drops and the speed is higher
than 37 mph (60 km/h), triggers a warning if
there is an unexpected change of direction.
This system is particularly useful on motor ways
and main roads.This system is a driving aid that cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
Activation/Deactivation
The system is activated and deactivated in the
vehicle configuration menu.
F

I
n the Driving/Vehicle menu
of the touch screen, select the
" Vehicle settings " tab then
" Safety " and activate/deactivate
" Lane depar ture warning
system".
Detection
You are alerted by the flashing of
this warning lamp in the instrument
panel, accompanied by an audible
signal.
No warning is transmitted while a direction
indicator is active.
Operating fault
The flashing and then constant illumination of
the warning lamp, accompanied by illumination
of the Ser vice warning lamp indicates a fault in
the system. Have the system checked by a CITROËN
dealer or a qualified workshop.
The detection may be impeded:
-
i
f the markings on the ground are worn,
-
i
f there is little contrast between the
markings on the road and the road
sur face,
-
i
f the windscreen is dirty,
-
i
n certain weather conditions: fog,
heavy rain, snow, shade, bright
sunlight or direct exposure to the sun
(low sun, leaving a tunnel, etc.).
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.

123
Blind spot monitoring
This system warns the driver of the presence of
another vehicle in the blind spot angle of their
vehicle (areas hidden from the driver's field
of vision), as soon as this presents a potential
danger.
A warning lamp appears in the door mirror on
the side in question:
-
i
mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a vehicle slowly. This driving aid system is designed to
improve safety when driving and is in no
circumstances a substitute for the use
of the interior rear view mirror and door
mirrors. It is the driver's responsibility to
constantly check the traffic, to assess the
distances and relative speeds of other
vehicles and to predict their movements
before deciding whether to change lane.
This system is a driving aid that cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
Activation/Deactivation
Activation and deactivation of the system is
done in the vehicle configuration menu.
F

I
n the Driving/Vehicle menu
of the touch screen, select the
" Vehicle settings " tab then
" Safety " and activate/deactivate
" Blind spot sensors ".
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The status of the system remains in memory
when the ignition is switched off. The system is automatically deactivated
when towing with a towing device
approved by CITROËN.
Operation
The alert is given by a warning lamp which
comes on in the door mirror on the side in
question as soon as a vehicle – car, lorry,
bicycle – is detected.
The following conditions must be met for this:
-

a
ll vehicles are moving in the same direction
and in adjacent lanes,
-

t
he speed of your vehicle must be between
7 and 87 mph (12 and 140 km/h),
-

y
ou overtake a vehicle with a speed
difference of less than 6 mph (10 km/h),
-

a v
ehicle overtakes you with a speed
difference of less than 16 mph (25 km/h),
-

t
raffic is flowing normally,
-

w
hen overtaking a vehicle over a certain
period of time and the vehicle being
overtaken remains in the blind spot,
-

y
ou are driving on a straight or slightly
curved road,
-

y
our vehicle is not pulling a trailer, a
caravan, etc.

Driving

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.

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.
