ESP CITROEN C4 PICASSO 2022 Workshop Manual

176
Using a camera placed at the top
o f 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.
The driver is then alerted by the message
" Ta k e c a r e ! ", 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
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.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.
Clean the front bumper, especially around
the radar, removing mud, snow, etc.
Parking sensors
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.
Driving

178
The rear parking sensors system will
be deactivated automatically if a trailer
or bicycle carrier is connected to
a
towing device installed in line with the
manufacturer's recommendations.
In this case, the outline of a
trailer is
displayed at the rear of the image of the
vehicle.
The parking sensors are deactivated while the
Park Assist system is measuring a
space.
For more information on the Park Assist , refer
to the corresponding section.
Operating limits
- A front 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.).
Operating fault
If the system fails, when reverse
gear is engaged this warning lamp
flashes for a
few seconds before
lighting up continuously, together
with the Service warning lamp.
A message appears, accompanied by an
audible signal.
Contact a
CITROËN dealer or a qualified
workshop. In bad or wintry weather, ensure that the
sensors are not covered by 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.
High pressure jet wash
When washing your vehicle, direct the
lance at least 30
cm away from the
sensors.
-

C

ertain 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.
Reversing camera
The reversing camera is activated automatically
when reverse gear is engaged.
Driving

180
This system is a visual aid that cannot in
a ny circumstances replace the need for
vigilance on the part of the driver.
The images provided by the camera(s)
may be distorted by the relief. The
presence of areas in shadow, bright
sunlight, or poor lighting conditions may
make the image dark and reduce contrast.
Forward vision
The camera situated on the front bumper is
activated and the views of the area to the
front left and the area to the front right of your
vehicle appear simultaneously in the instrument
panel.
Rear vision
The camera situated on the tailgate is activated
and the view of the area behind your vehicle is
displayed in the instrument panel and behaves
as a
reversing camera, regardless of the
position of the gear selector.
The blue outline represents the width of
your vehicle (without mirrors): its orientation
depends on the position of the steering wheel.
The red line represents the distance of 30 cm)
from the rear bumper and the two green lines
the distances of 1 m and 2 m respectively from
the rear bumper.
The rear vision is displayed automatically
when reverse gear is engaged, regardless
of the state of the system.
Vision 360
The cameras situated on the front and rear
bumpers as well as those below the door
mirrors activate and a view from above of your
vehicle in its close environment is generated
and is displayed in the instrument panel.
Opening a door or the tailgate will disrupt the
3 60 and rear views.
Installation of the very cold climate screen will
alter the image transmitted by the front camera.

At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could result in an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a
garage or heated
workshop for a
little while.
Travelling abroad
Certain fuels could damage your vehicle's
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For any additional information, contact a

Brake fluid level
The fluid level should be close to the
"MA X" mark. If it is not, check the
brake pad wear.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
The check and top-up must only be done with
the engine cold.
A low coolant level presents a
risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up. To avoid the risk of scalding when you need to
top up in an emergency, wrap a
cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.

In the case of vehicles fitted with
headlamp washers, when the fluid
reser voir low level is reached this
warning lamp comes on in the
instrument panel, accompanied by
an audible signal and a


message.
The warning lamp comes on when the ignition
is switched on, or every time the stalk is
operated, until the reser voir is refilled.
The next time you stop, have the screenwash/
headlamp wash reser voir topped up.
Diesel fuel additive level
(Diesel with particle filter)
The additive reser voir low level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a
message that
the particle filter additive level is
too low.
To p p i n g u p
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Level of AdBlue
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue and the SCR
system, and, in particular, topping up the tank,
refer to the corresponding section.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
