Safety



► To select the system, at speeds below 31 mph (50 km/h), press this button until its indicator lights up; this lamp appears in green
in the instrument panel.
The system becomes active at speeds below 19
mph (30 km/h).► When the vehicle begins its descent, you can release the accelerator and brake pedals; the
system regulates the speed:
– if the gearbox is in first or second gear, the speed decreases and the indicator lamp flashes rapidly,– if the gearbox is in neutral or if the clutch pedal is depressed, the speed decreases and the
indicator lamp flashes slowly; in this case, the maintained descent speed is lower.
On a descent, with the vehicle stationary, if you
release the accelerator and brake pedals, the
system will release the brakes to set the vehicle
gradually in motion.
The brake lamps light up automatically when the
system is regulating.
If the speed exceeds 19 mph (30 km/h), regulation is paused automatically, the
indicator lamp goes back to grey in the instrument panel, but the green indicator lamp in
the button remains on.
Regulation resumes automatically when the
speed falls below 19 mph (30 km/h) again, if the slope and pedal release conditions are met.
You can depress the accelerator or brake pedal
again at any time.
Switching off


► Press this button until its indicator lamp goes off; the indicator goes off in the instrument panel.
Above 45 mph (70 km/h), the system is
automatically deactivated; the indicator lamp in
the button goes off.
Malfunction
In the event of a system malfunction, this warning lamp comes on on the instrument
panel, accompanied by an onscreen message.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
Front seat belts

The front seat belts are fitted with a pyrotechnic
pretensioning system and a force limiting
system.

Driving
6• With the selector in position P and the brake
pedal depressed: with the selector at R, N,
D or M.
• Reverse gear engaged.
Special cases
The engine will restart automatically if all
conditions for operation are met again and in the
following cases.
– Vehicle speed exceeds 2 mph (3 km/h).– Some specific conditions (braking assistance, air conditioning setting, etc.).In these cases, this indicator lamp flashes for a few seconds, then goes off.
Malfunctions
In the event of a malfunction, the button’s
indicator lamp flashes briefly, then remains on.
Have the vehicle checked by a CITROËN dealer
or a qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
► Switch off the ignition then start the engine again with the key or the "START/STOP" button.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a CITROËN dealer or a
qualified workshop.
Under-inflation detection
This system automatically checks the pressures of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The 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 defined 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.
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 does not
always cause visible bulging 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 the four tyres when cold.
► If it is not possible to make this check immediately, drive carefully at reduced speed.

Driving
6Activating the function deactivates the Blind Spot Monitoring System.
You can deactivate the function at any time until the parking space entry or exit
manoeuvre begins, by pressing the arrow
located in the top left-hand corner of the
display page.
Selecting the type of manoeuvre

A manoeuvre selection page is displayed on the
touch screen: by default, the "Entry" page if the
vehicle has been running since the ignition was
switched on, otherwise, the "Exit" page.
► Select the type and side of the manoeuvre to activate the parking space search.
The selected manoeuvre can be changed at
any time, even while searching for an available
space.
Parking space search
► You should drive at a distance of between 0.50 m and 1.50 m from the row of parked vehicles, without ever exceeding 19 mph (30 km/h), until the system finds an available space.
The parking space search is suspended at
higher speeds. The function is automatically
deactivated if the vehicle speed exceeds 31 mph
(50 km/h).
For "parallel" parking, the space must
measure at least the length of your
vehicle plus 0.60 m.
For "bay" parking, the space must be at least
as wide as your vehicle plus 0.70 m.
If the parking sensors function has been
deactivated in the Driving/Vehicle touch
screen menu, it will be automatically
reactivated when the system is activated.


When the system finds an available space, " OK"
is displayed on the parking view, accompanied
by an audible signal.
Preparing for the manoeuvre
► Move very slowly until the request to stop the vehicle is displayed: " Stop the vehicle“,
accompanied by the “ STOP” sign and an audible
signal.
Once the vehicle has stopped, an instructions
page is displayed on the screen.
► To prepare for the manoeuvre, follow the instructions.
The start of the manoeuvre is indicated by the
"Manoeuvre under way" onscreen message
and an accompanying audible signal.
Reversing is indicated by this message:
“Release the steering wheel, reverse ”.
The Top Rear Vision and the parking sensors
are automatically activated to help you monitor
the area immediately surrounding your vehicle
during the manoeuvre.
During the manoeuvre
The system controls the vehicle’s steering. It gives instructions on the manoeuvring direction
when starting "parallel" entry and exit parking
manoeuvres, and for all "bay" entry manoeuvres.
These instructions are displayed as a symbol
accompanied by a message:
"Reverse".
