In sequential mode, it is not necessary to
release the accelerator pedal when changing
g e a r.
Changing from one gear to another only
occurs if the vehicle speed and engine speed
conditions allow; other wise the gearbox will
operate temporarily in automatic mode.
If the engine speed is too low or too high, the
gear selected flashes for a few seconds, then
the gear actually engaged is displayed.
Invalid value during manual operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).
You can change mode at any time by
moving the gear selector from D to M or
vice versa.
Stopping the vehicle
door is opened or approximately 45 seconds
a fter the ignition is switched off, an audible
signal sounds and a


message appears:

eposition the lever to position P ; the
audible signal stops and the message
disappears.
Whatever the parking circumstances, you must
apply the parking brake manually to immobilise
the vehicle if automatic operation has been
deactivated.
In all circumstances, ensure that the
selector is in position P before leaving
your vehicle.
Before switching off the engine, you can
engage position P or N to place the gearbox
in neutral. In both cases, apply the parking
brake to immobilise the vehicle, unless it is
programmed to automatic mode.
If the lever is not in position P , when the driver's In the event of a
battery failure, use the
chock to immobilise your vehicle.
Operating fault
If the gearbox malfunctions, the
Ser vice warning lamp comes on in
the instrument panel, accompanied
by a
message and an audible signal. Do not exceed 62
mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or
a

qualified workshop.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may then
feel a

substantial jolt when changing from P to
R and from N to R . This jolt will not cause any
damage to the gearbox.
Gear efficiency indicator
This system reduces 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.
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 deactivated.
With an automatic gearbox, the system is
only active in manual mode.

Have it checked by a CITROËN dealer or
a qualified workshop.
If a
fault occurs in STOP mode, the engine may
stall.
All of the instrument panel warning lamps come
on.
Depending on version, an alert message may also
be displayed, asking you to place the gear lever in
position N and press the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
The Stop & Start requires the use of
a 12 V battery of special specification and
technology.
All work on this type of battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
For more information on the 12
V batter y,
refer to the corresponding section.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
the risk of injury related to an automatic
change to START mode. Driving on flooded roads
Before driving in a
flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure of the four
tyres when the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
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.
Driving

143
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).
Other wise, add 0.3
bar (30 kPa) to the
values indicated on the label.
Under-inflation alert

n case of a puncture, use the temporary
puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is
reinitialised.Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to 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. Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Reinitialisation of the system is done on the
touch screen, with the ignition on and the
vehicle stationary.

Malfunction
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. In this case, under-inflation monitoring of the
tyres is no longer provided.
Have the system checked by a
CITROËN
dealer or a
qualified workshop.
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied
by illumination of the Ser vice warning lamp
indicates a
fault with the system.
A message appears, accompanied by an
audible signal.

If a vehicle presence is detected by the
r adar and if the speed selected is much
higher than the speed of that vehicle,
the system does not activate and the
alert message "Activation not possible,
conditions unsuitable" is displayed until
the driving conditions are safe to allow
activation of the system.
Exceeding the programmed
setting
It is possible to exceed the speed setting
temporarily by depressing the accelerator
pedal.
Then simply release the accelerator pedal to
return to the programmed speed.
If the programmed setting is unintentionally
exceeded, descending a
steep hill for example,
the speed setting in the instrument panel
flashes as a


warning.
Driving situations and
associated alerts
The table below describes the alerts and
messages displayed depending on the driving
situation.
The display of these alerts is not sequential.

Clean the front bumper regularly.
If the front bumper is to be repainted or
retouched, contact a CITROËN dealer
or a
qualified workshop. Certain types of
paint could inter fere with the operation of
the radar.
Malfunction
If the cruise control
malfunctions, dashes are
displayed instead of the
cruise control speed setting.
If this warning lamp comes
on, accompanied by an
alert message and an
audible signal, this confirms
a


malfunction.
The adaptive cruise control deactivates
automatically if the use of a "space-saver"
type spare wheel is detected or if there is
a

malfunction on the lateral brake lamps or
trailer brake lamps (for approved trailers).
The following situations may interfere with
the operation of the system or prevent it
from working:
-
p

snow, condensation, etc.).
In these situations, detection performance
may be reduced.
The message "SYSTEM INACTIVE:
Reduced visibility". is displayed to indicate
that the function is in standby. Have the system checked by a
CITROËN
dealer or a

qualified workshop.

fault with
the lateral brake lamps is detected.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of
your vehicle and be prepared to react at
any time to avoid an accident.
After an impact, the function automatically
stops operating. Contact a
CITROËN
dealer or a
qualified workshop to have the
system checked.
If the front bumper is to be repainted or

the radar.
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.
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 only be
modified via the touch screen's
Driving menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Operation
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.
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.

Driving

168
These levels of alert are based on the inter-
vehicle time between your vehicle and the
vehicle in front.
They take 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.Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The message " Vehicle close" is
displayed.
Level 2 (red) : visual and audible
alert, warning you that a
collision is
imminent.
The message " Brake!" is displayed.
Where the speed of your vehicle is too fast
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.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, inter venes following the alert if the
driver does not react quickly enough and does
not operate the vehicle's brakes. It aims to reduce the speed of impact or avoid
a
frontal collision by your vehicle where the
driver fails to react.
Operation
The system operates under the following
conditions:
-

T
he vehicle's speed does not exceed
37
mph (60 km/h) when a pedestrian is
detected.
-

T
he vehicle's speed does not exceed
50
mph (80 km/h) when a stationary vehicle
is detected.
-

T
he vehicle's speed is between 6 mph and
53
mph (10 km/h and 85 km/h) (versions
with camera alone) or 87
mph (140 km/h)
(versions with camera and radar) when
a
moving vehicle is detected.If the camera and/or radar have
confirmed the presence of a
vehicle
or a
pedestrian, this warning lamp
flashes once the function is acting
on the vehicle's brakes.
With an automatic 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.
With a
manual gearbox, in the event of
automatic emergency braking until the vehicle
comes to a
complete stop, the engine may stall.
