warning CITROEN C3 AIRCROSS 2022 Workshop Manual

145
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.
Using the camera, this function acts on the
vehicle's braking system.
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 according to the driving
actions from the driver, such as movement
of the steering wheel or pressing 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 gearbox, in the event
of automatic emergency braking until the
vehicle comes to a complete stop, keep
the brake pedal down to stop the vehicle
from starting off again.
Specific conditions for operation
The vehicle's speed must be between 3 mph
a nd 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 defective.
The ASR system must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
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.
The system can be deactivated or activated via
the vehicle settings menu. Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a message.

Malfunction
There may be interference in the operation
of the camera or it may not work at all in
the following situations:
-
p
oor visibility (inadequate street
lighting, 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.),
-

c
amera masked (mud, frost, snow,
condensation, etc.).
In these situations, detection performance
may be reduced.
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
mask the camera's view.
Fatigue detection system
Take a break as soon as you feel tired or at
least every two hours. 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.
Without audio system
F In the " DRIVE ASSIST " menu on the
instrument panel display, activate/deactivate
" VIGILANCE ALT " (Fatigue Detection
S yste m).
With audio system
F In the " Personalisation-
configuration " menu, activate/
deactivate " Fatigue Detection
System ".
With touch screen
F In the Driving/Vehicle menu,
select the " Vehicle settings "
tab, then " Security" and
activate/deactivate " Fatigue
Detection System ".
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).
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.
This alert takes the form of a display message
encouraging you to take a break, accompanied
by an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Driving

147
If the driver does not follow this advice, the
alert is repeated hourly until the vehicle is
stopped.
The system resets itself if one of the following
conditions is met:
-
e
ngine running, the vehicle has been
stationary for more than 15


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 speed of the vehicle drops
below 40
mph (65 km/h), the system goes
into standby.
The driving time is counted again once the
speed is above 40
mph (65 km/h).
Driver inattention alert
Depending on version, the "Driving time
warning" may be combined with the "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.
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, masked
(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.

Lane Departure Warning
System
System which uses a camera to recognise solid
or broken lines and detects the involuntary
crossing of longitudinal traffic lane markings on
the road.
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 driver’s
own vigilance.
Manual deactivation/
reactivation

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 driver’s
own vigilance.
Activation/Deactivation
The system can be activated or deactivated
from the vehicle configuration menu.
F

I
n the Driving/Vehicle menu,
select the " Vehicle settings "
tab, then " Security" and

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 towbar 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, cycle
– 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

front and behind are confused with a lorry or
a stationary object.
Malfunction
In the event of a fault with the
system, this warning lamp flashes
for a few moments in the instrument
panel, accompanied by the Ser vice
warning lamp coming on and the
display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet sur face or
the transition from a dry area to a wet area
can cause false alerts (e.g. the presence
of a cloud of water droplets in the blind
spot is interpreted as a vehicle).
In bad or wintry weather, 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.

Malfunctions
If a fault occurs, this warning lamp
comes on accompanied by a
message and an audible signal.
In the event of a fault with the
power steering, this warning lamp
flashes in the instrument panel,
accompanied by a message.
If the lateral distance between your vehicle
and the space is too great, the system may
not be able to measure the space.
Any object projecting beyond the dimensions
of the vehicle (e.g. a ladder on the roof or a
towball) will not be 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.High pressure jet washing
When washing your vehicle, keep the lance at
least 12 inches (30
cm) away from the sensors.
Contact a CITROËN dealer or a qualified
workshop.
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 ever y time the tyre
pressures are adjusted or a wheel changed .
The system triggers an alert as soon as it
detects a drop in the 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 worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
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.
