Driving
6partially recharge the traction battery, without
affecting the charge level indicator.
Progressive Hydraulic
Cushions
This suspension system with progressive hydraulic cushions improves driving comfort by
filtering out the imperfections and demands of
the road surface.
Each shock absorber is equipped with a
hydraulic compression stop (at the base) and a
hydraulic rebound stop (at the top).
Depending on the intensity of the shock to be
absorbed, these stops provide the vehicle with a
greater freedom of movement or gradually slow
down the amount of movement in order to avoid
any sudden jolts at the end of travel.
Unlike conventional suspension which absorbs
the energy but then partially returns some of it,
this active suspension absorbs and dissipates
this energy, without producing any rebound.
Driving modes
The number and type of driving modes available depend on the vehicle’s engine and equipment.
Driving modes are selected using one of the
following controls, depending on version:




1. Pressing the control activates Eco mode. The
indicator lamp comes on.
2. Pressing the control activates Sport mode.
The indicator lamp comes on.
3. Pressing the control displays the modes on
the instrument panel.
The selected mode is activated immediately.
With petrol / Diesel engines
Each time the ignition is switched on, Normal
mode is selected by default.
Eco
Reduces energy consumption by restricting the
performance of the heating and air conditioning
systems, although it does not deactivate them.
Normal
Restores the vehicle’s original settings.
Sport
Enables more dynamic driving with action on the
power steering, accelerator and gear changes
(with an automatic gearbox).
Depending on version, with an EAT8
gearbox and the selector in position D
(except Sport mode), fully releasing the
accelerator pedal allows free-wheeling which
can save fuel.
A drop in engine speed is normal (rev counter
at idle, drop in engine noise).
With rechargeable hybrid
engine
Each time the ignition is switched on, Electric
mode is selected by default.
Electric
Allows driving using 100% electrical energy.
The maximum speed is approximately 84 mph
(135
km/h).
When starting the vehicle, if the conditions do
not allow the activation or retention of Electric
mode, the message "Electric mode currently
unavailable" is displayed on the instrument
panel. The vehicle automatically changes to
Hybrid mode.
If a blue LED comes on under the interior rear
view mirror, visible from outside the vehicle, this
confirms that you are driving in Electric mode.

6Malfunction
These warning lamps come on in the event of a malfunction,
accompanied by the display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Gear shift indicator
(Depending on engine.)
System which reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and the
vehicle's equipment, the system may advise to
skip one or more gears.
Gear shift recommendations should not be
considered compulsory. 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 operation.
The information appears in the instrument panel, in the form of an arrow and the
recommended gear.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (request for power, acceleration,
braking, etc.).
The system never suggests:
–

engaging first gear
.
–

engaging reverse.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move 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.
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.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
To deactivate/reactivate the function:




► Press the button.
A message in the instrument panel confirms the
change of status.
When the function is deactivated, the orange
indicator lamp is lit; if the engine was in standby,
it restarts immediately.
Associated indicator lamps
Function activated.
Function deactivated or malfunction.

Driving
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
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.
Tyre 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 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

value in steps of + or - 1 mph (km/h).
► Press and hold button 2 or 3 to change the
value in steps of + or - 5 mph (km/h).
Pressing and holding button 2 or
3 results in a rapid change in the speed
of the vehicle.
As a precaution, we recommend setting a cruise speed fairly close to the current
speed of your vehicle, to avoid any sudden
acceleration or deceleration of the vehicle.
To change the cruise speed setting using memorised speed settings and from the touch
screen:
► Press button 5 to display the memorised
speed settings.
► Press the touch screen button for the desired
speed setting.
Programmable cruise
control

Highway Driver Assist
Only available on versions with automatic
gearbox.
This system automatically adjusts the speed and
corrects the trajectory of the vehicle, using the
Adaptive Cruise Control with Stop&Go function
in conjunction with the Lane Positioning Assist.
These two functions must be activated and in
operation.
This system is especially suitable for driving on
motorways and main roads.
For more information on Adaptive Cruise
Control and Lane Positioning Assist, refer to
the corresponding sections.
The system assists the driver by acting on the steering, acceleration and braking,
within the limits of the laws of physics and the
capabilities of the vehicle. Certain road
infrastructure elements or vehicles present on
the road may not be properly seen or may be
poorly interpreted by the camera and radar,
resulting in an unexpected change in
direction, a lack of steering correction and/or
inappropriate management of acceleration or
braking.
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
automatically manages the acceleration and
deceleration of the vehicle.
With the Stop function , the system manages
the braking until the vehicle comes to a complete
stop.
With the Stop
& Go function, the system
manages the braking until the vehicle comes to a
complete stop and the restarting of the vehicle.
The brake lamps come on if the vehicle is slowed down by the system.
It can be dangerous to drive if the brake
lamps are not in perfect working order.


To do so, it has a camera located at the top of
the windscreen and, depending on version, 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 poorly
interpreted by the camera and/or radar (e.g. a
lorry), which may lead to a poor assessment
of the distances and lead to the vehicle
inappropriately accelerating or braking.

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 the driver
presses the brake pedal.
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.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.

switch or at least two brake lamps is detected.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
It is possible that 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.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
Collision Risk Alert
This function warns the driver that their vehicle
is at risk of a collision with the vehicle in front, or
with a pedestrian or cyclist present in their traffic
lane.
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 Driving /
Vehicle touch screen menu.
►

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 degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
the instrument panel.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
steering wheel, etc.) to trigger the alert at the
most relevant moment.
Level 1 (orange): visual alert only,
warning that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
warning that a collision is imminent.
The message "Brake! " is displayed.
Where the speed of your vehicle is too
high approaching another vehicle, the
