In very cold conditions (ice), applying the
parking brake is not recommended.
To immobilise the vehicle, engage a gear or
place the chocks against one of the wheels.
With an automatic gearbox or drive
selector, mode P is automatically
selected when the ignition is switched off. The
wheels are blocked.
For more information on Free-wheeling, refer
to the corresponding section.
With an automatic gearbox or drive
selector, while mode N is selected,
opening the driver’s door triggers an audible
signal. It stops when the driver's door closes
again.
Deactivating automatic
operation
In some situations, for example when it is
extremely cold or when towing (e.g. caravan,
breakdown), it may be necessary to deactivate
automatic operation of the system.
►

Start the engine.
►


Use the control to apply the parking brake, if
it is released.
►

functions, using the control, allow the parking
brake to be applied and released.
►
Follow this procedure again to reactivate
automatic operation (confirmed by the indicator
lamp on the instrument panel going out).
Emergency braking
If depressing the brake pedal fails to provide
effective braking or in exceptional circumstances
(e.g.
driver unwell, assisted driving), the vehicle
can be braked by sustained pulling on the
electric parking brake control. Braking continues
for as long as the control is kept pulled, and
ceases when the control is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If emergency braking malfunctions, the message
"Parking brake fault" will be displayed on the
instrument panel.
If the ABS and DSC systems
malfunction, indicated by lighting
one or both warning lamps on the instrument
panel, the vehicle’s stability is no longer ensured.
►

In this case, ensure the vehicle's stability by
successive and repeated "pull-release" actions
on the electric parking brake control until the
vehicle comes to a complete stop.
6-speed manual gearbox
Engaging 5th or 6th gear
► Move the gear selector fully to the right to
engage 5th or 6th gear.
Failure to follow this instruction could
cause permanent damage to the gearbox
(inadvertent engagement of 3
rd or 4th gear).
Engaging reverse gear

► Raise the ring under the knob and move the
gear selector to the left, then forwards.

Drive selector (Electric)

The drive selector is a pulse selector with a
regenerative braking function.
The drive selector provides traction control
based on the driving style, the road profile and
the vehicle load.
With regenerative braking activated, it also
manages engine braking when the accelerator
pedal is released.

Information displayed on
the instrument panel
When the ignition is switched on, the drive
selector status is displayed on the instrument
panel:
P : Park.
R : Reverse.
N : Neutral.
D : Drive (automatic forward gear).
B : Brake (automatic forward gear with
regenerative braking function activated).
Operation
► In mode N, with your foot on the brake pedal,
push without passing the point of resistance: •

Forwards, mode
R is selected.
•

Backwards, mode D

is selected.
Release the selector fully after each push; it
will then return to its initial position.

resistance, mode D is selected.
►

In mode
D, push forwards past the point of
resistance,
mode R is selected.
►

T
o return to mode N, push without passing
the point of resistance.
Regenerative braking
With the Brake function and when
decelerating
The Brake function emulates engine braking,
slowing the vehicle with no need to depress the
brake pedal. The vehicle slows more quickly
when the driver releases the accelerator pedal.
The energy recovered when the accelerator
pedal is released is then used to partially
recharge the traction battery, thereby increasing
the vehicle's driving range.
The resulting deceleration of the vehicle does not cause the brake lamps to come
on.
► From mode D, press button B to activate/
deactivate the function (the button lights up when
the function is activated).
B is displayed on the instrument panel.
The system status is not saved when the ignition
is switched off.
In some situations (e.g. battery full,
extreme temperatures), the amount of
regenerative braking may be temporarily
limited, resulting in less deceleration.
The driver must remain alert to traffic
conditions and must always be ready to use
the brake pedal.
With the brake pedal
When the brake pedal is depressed, the
intelligent braking system automatically recovers
some of the energy and uses it to recharge the
traction battery.
This energy recovery also reduces use of the
brake pads, thereby limiting their wear.
The driver may experience a different sensation when depressing the brake
pedal compared to a vehicle without
regenerative braking.
Driving modes
The driving modes available depend on the engine and equipment of the vehicle.

6Malfunction
If the event of a malfunction, these
warning lamps light up on the
instrument panel, accompanied by the display of
a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Gear shift indicator
(Depending on engine)
This system is designed to reduce fuel
consumption by recommending the most suitable
gear.
Operation
Depending on the driving situation and
the vehicle's equipment, the system may
recommend skipping one or more gears.
Gear engagement recommendations are
not to be considered mandatory. Indeed, the
configuration of the road, the traffic density and
safety remain determining factors when choosing
the best gear. Therefore, the driver remains
responsible for deciding whether or not to follow
the system’s advice.
The system cannot be deactivated.
With an automatic gearbox, the system is
only active in manual operation.
The information appears on the instrument panel, in the form of an arrow
and the recommended gear.
The system adapts the gear change instructions according to the driving
conditions (e.g.
slope, load) and driving style
(e.g.
power demand, acceleration, braking).
The system never suggests:
–

engaging first gear;
–


engaging reverse gear
.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
red
lights, traffic jams). The engine automatically
restarts - START mode - as soon as the driver
indicates the intention of moving off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
The settings are changed via the Driving/Vehicle touch screen menu.
A message on the instrument panel confirms the
change of status.
When the function is deactivated, if the engine
was in standby, it restarts immediately.
Associated indicator lamps
Function activated.
Function deactivated or malfunction.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
any risk of injury caused by the engine
restarting automatically.
Driving on flooded roads
Before entering into a flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving
recommendations, particularly on flooded
roads, refer to the corresponding section.
Operation
Main conditions for operation
– The driver ’s door must be closed.
– The driver's seat belt must be fastened.

Driving
6Tyre under-inflation detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
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.
It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.
The tyre under-inflation detection cannot, in any circumstances, 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), especially 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 energy 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 monthly
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 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.

100
Driving
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.
With the vehicle stationary, the system is
reinitialised via the Driving/V ehicle touch
screen menu.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have it checked by a CITROËN dealer or a
qualified workshop.
Non-standard or 'space-saver' spare
wheel
The use of this type of spare wheel may
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp
comes on and disappears once the wheel
has been replaced by one of uniform size (the
same as the others), the pressure readjusted
and the
reinitialisation carried out.

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,

104
Driving
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account to ensure
you observe the speed limit.
For the system to work properly when
changing countries, the speed unit of the
instrument panel must match that of the
country you are driving in.
Automatic sign reading is a driving aid system and does not always display the
correct speed limits.
The speed limit signs present on the road
always take priority over those displayed by
the system.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
Specific speed limits, such as those for
heavy goods vehicles, are not displayed.
The display of the speed limit on the
instrument panel is updated when passing
a speed limit sign intended for cars (light
vehicles).
Activation/Deactivation
By default, the system is automatically activated
at every engine start.
The settings are changed via the Driving/Vehicle touch screen menu.
Information displayed on
the instrument panel


1. Detected speed limit indication
or
2. End of speed limit indication


The system is active but is not detecting speed
limit information.


On detecting speed limit information, the system
displays the value.


For a suggested maximum speed, the first time
that the vehicle exceeds it
by more than 3 mph
(5
km/h) (e.g. 59 mph (95 km/h)), the speed is
displayed and flashes for 10 seconds (depending
on version).
Operating limits
The system does not take account of reduced
speed limits, especially those imposed in the
following cases:
–

Atmospheric pollution.
–

Towing.
–

Driving with a space-saver type spare wheel
or snow chains fitted.
–


T
yre repaired using the temporary puncture
repair kit.
–

oung drivers.
The system may not display the speed limit if it
does not detect a speed limit sign within a preset
period and in the following situations:
–

Road signs that are obstructed, non-standard,
damaged or bent.
–


Obsolete or incorrect maps.
Speed setting
recommendations
The driver can select the speed displayed by the
Road signs recognition system as the speed
setting for the speed limiter, cruise control or
adaptive cruise control using the OK button.
In the event of rain detection, the system offers
the driver a speed setting lower than the speed
read/from the map in order to adapt to weather
conditions (e.g.on motorways, the proposed
speed is 68 mph (110 km/h) instead of 81 mph
(130 km/h).
