Fatigue detection system

Depending on version, the "Driving time
warning" may be combined with the "Fatigue
detection system".

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)).

Once the system considers that the behaviour
of the vehicle suggests a certain level of fatigue
or inattention by the driver, it triggers the first
level of alert.
The driver is then alerted by the message
"Take care!

", accompanied by an audible

signal.

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
surface 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:
- poor visibility (inadequate lighting

of the roadway, falling snow, heavy
rain, dense fog, ...),

- dazzle (headlamps of an oncoming

vehicle, low sun, reflections on
a damp road, leaving a tunnel,
alternating shade and light, ...),

- windscreen area located in front

of the camera: dirty, misted, frost-
covered, snow-covered, damaged
or covered by a sticker,

- lane markings absent, worn,

masked (snow, mud) or multiple
(roadworks, ...),

- close to the vehicle ahead (lane

markings not detected),

- roads that are narrow, winding, ...

This system indicates the proximity of an
obstacle (e.g. pedestrian, vehicle, tree, gate)
which comes within the field of detection of
sensors located in the bumper.
Certain types of obstacle (e.g. stake,
roadworks cone) detected initially will no longer
be detected at the end of the manoeuvre, if
they are located in blind spots in the sensors'
field of detection.

Parking sensors

This system cannot in any
circumstances replace the need for
vigilance on the part of the driver.

The system is switched on by engaging reverse
gear.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.

The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
The sound emitted by the speaker (right-hand
or left-hand) indicates the side on which the
obstacle is located.
When the distance between the vehicle and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.

Rear parking sensors

This supplements the audible signal by
displaying bars in the screen or the instrument
panel which move progressively nearer to
the vehicle. When the obstacle is near, the
"Danger" symbol is displayed.

Front parking sensors

The sound emitted by the speaker (front
or rear) indicates whether the obstacle
is in front or behind.

The system will be deactivated
automatically if a trailer is being
towed or a bicycle carrier is fitted on
a towbar (vehicle fitted with a towbar
installed in line with the manufacturer's
recommendations).

In bad weather or in winter, 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.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking
sensor system.

As an 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 remains below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in forward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).

The parking sensors can be deactivated in the
touch screen.
F In the Driving

menu, select the "Driving

functions" tab, then "Parking sensors

".

Operating fault

In the event of a malfunction of
the system, when reverse gear is
engaged, this warning lamp flashes
for a few moments then stays on
continuously.

This indicator comes on in the
instrument panel.
A new selection reactivates the function.

High pressure jet wash
When washing your vehicle, do not
direct the lance within 30 cm of the
sensors.

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.

Reversing camera

Clean the reversing camera regularly
using a soft, dry cloth.

The reversing camera is activated automatically
when reverse gear is engaged.
Depending on version, the image is displayed
in the touch screen or the instrument panel.

The superimposed representation of guide
lines helps with the manoeuvre.

The blue lines represent the general direction
of the vehicle (the difference corresponds to
the width of your vehicle without the mirrors).
The red lines represent a distance of about
30 cm beyond the edge of your vehicle's rear
bumper.
The green lines represent distances of
about 1 and 2 metres beyond the edge of your
vehicle's rear bumper.
The turquoise blue curves represent the
maximum turning circle.

The reversing camera cannot in any
circumstances replace the need for
vigilance on the part of the driver.

Opening the tailgate causes the display
to disappear.

The reversing camera function may be
supplemented by parking sensors.

High pressure jet washing
When washing your vehicle, do not
direct the lance within 30 cm of the
camera lens.

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 (e.g. other
vehicles).
Some deformation of the image is normal.
It is normal to be able to see part of the
number plate at the bottom of the screen.

360 Vision

This system provides a view in the instrument
panel of the near surroundings of your vehicle,
using cameras mounted at the front and rear of
your vehicle and under the door mirrors.
Depending on the angle of view chosen (front
view, rear view or 360° panoramic view),
360 Vision provides special visual assistance
in particular driving conditions such as when
entering a blind junction or manoeuvring in
areas of reduced visibility.
Once activated, this function operates up to
9 mph (15 km/h). Above 18 mph (30 km/h), the
function is deactivated automatically.

This system is a visual aid which in no
circumstances can replace the need for
vigilance on the part of the driver.
The images provided by the cameras
may be deformed by the relief. The
presence of areas in shade, in sunny
conditions, or of low ambient light may
darken the image and reduce contrast.

Forward vision

The camera located in the front bumper is
activated and views of the areas located at
front left and front right appear simultaneously
in the instrument panel.

Rear vision

The camera located in the tailgate is activated
and the view of the area behind your vehicle is
displayed in the instrument panel and behaves
like a reversing camera, whatever the position
of the gear selector lever.
The blue lines represent the width of your
vehicle (excluding mirrors): they move
according to the position of the steering wheel.
The red line represents a distance of 30 cm
from the rear bumper, and the two green
lines, 1 m and 2 m from the rear bumper,
respectively.

Rear vision is displayed automatically
when engaging reverse, regardless of
the state of the system.

Park Assist

This system provides active assistance with
parking. It detects a parking space then
operates the steering to park in the space.
It operates the steering while the driver
manages the accelerator, brakes, gears and
clutch (manual gearbox). During phases of
entry into and exit from a parking space, the
system provides visual and audible information
to the driver in order to make the manoeuvres
safe. It may be necessary to move forwards
and backwards more than once.

During a manoeuvre, the steering
wheel turns quickly: do not hold the
steering wheel, do not place your
hands between the spokes of the
steering wheel and take care with
loose and bulky clothing (scarves, ties,
handbags...) - Risk of injury!

When Park Assist is activated, it
prevents a change to STOP mode of
Stop & Start. In STOP mode, activation
of Park Assist restarts the engine.

This manoeuvring assistance system
cannot, in any circumstances, replace
the need for vigilance on the part of the
driver.
The driver must remain in control of their
vehicle ensuring that the space remains
clear throughout the manoeuvre.
In some circumstances, the sensors may
not detect small obstacles located in
their blind spots.

The driver can take control at any time by
gripping the steering wheel.

The Park Assist system provides assistance for
the following manoeuvres:

A.

Entry into a parallel parking space

B.

Exit from a parallel parking space

C.

Bay parking

The Park Assist system takes control
of the power steering for a maximum
of 4 manoeuvre cycles. The function
is deactivated after these 4 cycles.
If you think that your vehicle is not
positioned correctly, you should then
take control of the steering to carry out
the manoeuvre.

The Park Assist system cannot work
with the engine off.

198

Driving

C4-Picasso-II_en_Chap04_conduite_ed02-2016

The sequence of manoeuvres and the
driving instructions are displayed in the
instrument panel.

You should always check the
surroundings of your vehicle before
starting a manoeuvre.

The assistance is
deactivated: the display of
this symbol indicates that
the steering manoeuvres
are no longer controlled by
the system: you must take
control of the steering.

The assistance is
activated: the display of this
symbol and a speed limit
indicate that the steering
manoeuvres are controlled
by the system: do not touch
the steering wheel.

The parking sensors function is
not available during parking space
measurement. It intervenes later when
manoeuvring to warn you that your
vehicle is approaching an obstacle: the
audible signal becomes continuous
when the obstacle is less than thirty
centimetres away.
If you have deactivated the parking
sensors, they are automatically
reactivated during assisted parking
manoeuvres.

Activation of Park Assist deactivates the
Blind Spot Monitoring System.

Anything projecting beyond the envelope
of the vehicle (a ladder on the roof, for
example) is not taken into account by the
Park Assist system during a manoeuvre.

In bad weather or in winter, ensure that
the sensors are not covered by road
dirt, ice or snow.
In the event of a fault, have the system
checked by a CITROËN dealer or a
qualified workshop.

If the system is deactivated during a
manoeuvre, the drive should reactivate
it to repeat the measurement.

In the event of a fault, this warning

Driving

C4-Picasso-II_en_Chap04_conduite_ed02-2016

Under-inflation detection

The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised every time the
tyre pressures are adjusted or a wheel
changed

.

The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres.

The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous conditions
(high loading, high speed, long journey).

System which automatically checks the pressures of the tyres while driving.

The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
For more information on the
Identification markings, refer to the
corresponding section.

Driving with under-inflated tyres
increases fuel consumption.

Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than
6 miles (10 km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.

206

Driving

C4-Picasso-II_en_Chap04_conduite_ed02-2016

Under-inflation alert

Reinitialisation

This is given by fixed illumination of
this warning lamp, accompanied by
an audible signal and, depending on
equipment, the display of a message.

It is necessary to reinitialise the system every
time one or more tyre pressures are adjusted,
and after changing one or more wheels.

F

Reduce speed immediately, avoid

excessive steering movements and sudden
braking.

F Stop the vehicle as soon as it is safe to

do so.

F

If you have a compressor, such as the one

in the temporary puncture repair kit, check
the pressures of the four tyres when cold.

F

If it is not possible to make this check

immediately, drive carefully at reduced
speed.

or
F In the event of a puncture, use the

temporary puncture repair kit or the spare
wheel (depending on equipment).

The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check.

The alert is maintained until the system
is reinitialised.

Snow chains

The system does not have to be
reinitialised after fitting or removing
snow chains.

Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
The under-inflation alert can only
be relied on if the reinitialisation of
the system has been done with the
pressures in the four tyres correctly
adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
