2022 CITROEN C4 CACTUS warning

106
There is an audible signal upon
engagement of reverse.
If reverse gear is requested when moving, the
warning lamp N flashes and the gearbox goes
into neutral automatically.
To engage reverse, stop the vehicle then, with
your foot on the brake pedal, press control N ,
then R .
Stopping the vehicle
Before switching off the engine, you can:
-
p ress control N to be in neutral,
or
-

l
eave the vehicle in gear; in this case the
vehicle cannot be moved.
For all parking situations, you must apply
the parking brake to immobilise the
vehicle.
When immobilising the vehicle with the
engine running, you must select neutral N .Before doing anything under the bonnet,
ensure that control N has been pressed
and that the parking brake is applied.
Operating fault
With the ignition on, illumination of
this warning lamp, accompanied by
an audible signal and a message,
indicates a gearbox fault.
Have it checked by a CITROËN dealer or a
qualified workshop.
Gear efficiency indicator
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears. The system is only active on vehicles fitted
with a manual gearbox.
On certain BlueHDi Diesel versions with
manual gearbox, in certain driving conditions
the system may suggest changing into neutral
so that the engine can go into standby (STOP
mode with Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal.
-
T
he system may suggest that you engage a
higher gear.
Gear efficiency recommendations are for
information only. In fact, the road layout, the
traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued
by the system.
This function cannot be disabled.
The information appears in the instrument
panel in the form of an arrow.
Driving

107
The system adapts its gear change
recommendation according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e
ngaging first gear,
-
enga

ging reverse gear.
-
enga

ging a lower gear.
On vehicle fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
Hill start assist
System which keeps your vehicle stationary
for a short time (approximately two seconds)
when starting on a gradient, the time it takes
to move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain conditions of gradient are met,
-

t
he driver's door is closed.
The hill start assist system cannot be
deactivated. Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp is showing fixed on
the instrument panel.
Operating fault
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal.
With a manual gearbox
, if you are in first gear
or in neutral.
With an automatic gearbox , if you are in D
or M .
With an electronic gearbox , if you are in D.On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
If a fault in the system occurs, this warning
lamp comes on accompanied by a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.

Collision Risk Alert and
Active Safety Brake
Activation and operating
conditions
The system is activated from 3 mph (5 km/h).
It takes account of:
-
r
egistered vehicles running in the same
direction or stationary,
-

p
edestrians in the traffic lane (bicycles,
motorcycles, animals and objects on the
road are not necessarily detected).
This system is designed to assist the
driver and improve road safety.
It is the driver's responsibility to
continuously monitor the state of the
traffic, observing the driving regulations.
This system does not avoid the need for
vigilance on the part of the driver.
As soon as the system detects a potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This
may cause a slight noise and a slight
sensation of deceleration.
This system is a driving aid that includes three
functions.
Collision Risk Alert:
it warns the driver if their
vehicle is at risk of collision with the vehicle in
front or a pedestrian present in their traffic lane.
Intelligent emergency braking assistance :
it supplements the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it intervenes following
the alert if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, it contributes
towards avoiding a collision or limiting
its severity by reducing the speed of your
vehicle.
The vehicle has a camera located at the top of
the windscreen. In the following cases, deactivating the
system via the vehicle's configuration menu is
recommended:
-
w hen towing a trailer,
- w hen carrying long objects on roof bars or a
roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling stand
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-
fo

llowing impact damage to the windscreen
close to the detection camera,
-

i
f the brake lamps are not working.It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay alert and be
prepared to react at any time to avoid an
accident.

Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of
alert can be triggered and displayed in the
instrument panel.Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The message " Vehicle close" is
displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front. Level 2 (red) : visual and audible
alert, warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment. Where the speed of your vehicle is too
high approaching another vehicle, the first
level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important:
alert level 1 is never displayed
when the " Close" trigger threshold has
been selected.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or a
pedestrian present in your traffic lane.
The current threshold can be modified via the
vehicle configuration menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in the
memory when the ignition is switched off.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid
a collision, this system will supplement the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
Active Safety Brake
This function, also called automatic emergency
braking, aims to reduce the speed of impact or
avoid a frontal collision with your vehicle where
the driver fails to react.
Driving

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.

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
