Driving
6The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–
worsens road-holding,
–
lengthens braking distances,
–
causes premature wear of the tyres,
–
increases fuel consumption.
The inflation pressures specified for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
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.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►
Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►
Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected may not always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►
Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►
If it is not possible to carry out this check
immediately
, drive carefully at reduced speed.
►
In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre
blow-out. This is because analysis of the
values read by the wheel's speed sensors
can take several minutes.
The alert may be delayed at speeds below
25 mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is reinitialised.
Reinitialisation
► The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
152
Driving
With dashboard button
► With the vehicle stationary , press this
button for about 3 seconds then release it.
Reinitialisation is confirmed by an audible signal.
Without dashboard button
With the vehicle stationary, the
system is reinitialised via the
vehicle configuration menu.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have it checked by a CITROËN dealer or a
qualified workshop.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climatic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
monitor traffic conditions, assess the distance
and relative speed of other vehicles, and
anticipate their manoeuvres before using the
direction indicator and changing lanes.
These systems do not make it possible to
exceed the laws of physics.
Driving aids
You should hold the steering wheel with
both hands, always use the door and interior
mirrors, always leave your feet close to the
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar(s)
The operation of the radar(s), along with
any associated functions, may be affected
by the accumulation of dirt (e.g.
mud, ice),
in poor weather conditions (e.g.
heavy rain,
snow), or if the bumpers are damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar(s).
Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.

Cruise control - Specific
recommendations.
This system automatically maintains the vehicle’s speed at the value programmed
by the driver (speed setting), without the use of
the accelerator pedal.
Cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph
(40
km/h).
With a manual gearbox, third gear or higher must
be engaged.
With an automatic gearbox, mode
D
or second
gear or higher in mode
M
must be engaged.
With a drive selector, mode
D or B must be
engaged.
Cruise control remains active after
changing gear, regardless of the gearbox
type, on engines fitted with the Stop & Start
function.

Adaptive cruise control
Refer to the General recommendations
on the use of driving and
manoeuvring aids and to Cruise control
- particular recommendations.
This system automatically maintains the speed of your vehicle at a value which
you set (speed setting), while keeping a safe
distance from the vehicle in front (target vehicle),
and which has been set beforehand by the
driver. The system controls the vehicle's
acceleration and deceleration automatically
using only engine braking (as if the driver had
pressed the "-" minus button).
To do this, it uses a radar located in the front
bumper.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
If the driver operates a direction indicator
to overtake a slower vehicle, the cruise
control allows the vehicle to temporarily
approach the vehicle in front to assist the
overtaking manoeuvre, without ever
exceeding the speed setting.
Some vehicles present on the road may
not be properly seen or may be
misinterpreted by the radar (e.g. a lorry),
which may lead to a poor assessment of
distance and lead to the vehicle accelerating
or braking inappropriately.

166
Driving
Brake system operational.
Seat belts fastened for all passengers.
Stabilised speed on roads with no or low
curvature.
This warning lamp lights up on the instrument panel without any additional
message, to indicate that the automatic braking
system is not available.
This is a normal behavior indicating that a
condition is not fulfilled and which does not
request the support of a workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the
system via the vehicle's configuration menu is
recommended, for instance:
–
T
owing a trailer (particularly a trailer without its
own braking system).
–
Carrying long objects on roof bars or roof rack.
–
Driving with snow chains.
–
Using an automatic car wash.
–
Performing any maintenance (e.g.
changing a
wheel, working inside the engine compartment).
–
Placing the vehicle on a rolling bench in a
workshop.
–
T
owing the vehicle.
–
Following a front bumper deformation.
–
Following
an impact to the windscreen close to
the detection camera.
The system diagnoses permanently its capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions
(e.g. sensor initialization, board voltage out of
regular range, activation of stability system).
Therefore, the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle (keep within the GVW limit and load
height limits for roof bars).
Following an impact (e.g. a collision), the
system is automatically deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the vehicle configuration menu with the audio
system or touch screen.
►
Select one of the three pre-defined
thresholds: "Far", "Normal" or "Close".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own
vehicle and the object identified for the
collision risk, and the operation of the vehicle
(e.g.
actions on the pedals, steering wheel) to
trigger the alert at the most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake! " is displayed.
While approaching a vehicle too quickly,
the level 2 alert may be displayed
directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically
at lower speed.
167
Driving
6It is possible that collision warnings are
not given, are given too late or seem
unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
Intelligent emergency
braking assistance (iEBA)
This function supplements braking in the event
that the driver brakes, but not enough to avoid a
collision.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake
This function, also called "automatic emergency
braking", intervenes after the acoustic alert if the
driver does not operate the brake pedal quickly
enough.
The system aims at reducing the speed of
impact or avoiding a collision if the driver fails to
react.
The speed will be reduced by a maximum of 16 mph (25 km/h) (versions
with camera only) or by a maximum of 31
mph (50
km/h) (versions with camera and
radar).
Operation
The system operates subject to the following
conditions:
–
At reduced speed in an urban environment,
when a stationary vehicle, pedestrian or cyclist
is detected.
–
The vehicle's speed is between 6 mph and
53 mph (10
km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle
is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
During the flashing time, the function is not
available.
With an automatic gearbox, in the event of
automatic emergency braking, keep the brake
pedal depressed, also after a complete stop is
reached, to prevent the vehicle from rolling away.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can override the automatic emergency braking at any time by firmly
turning the steering wheel and/or firmly
depressing the accelerator pedal.
