The 400
V traction battery 2 uses Lithium-Ion
technology. It stores and supplies the energy
required for the operation of the electric motor,
air conditioning and heating. Its charge level is
represented by an indicator and a reserve power
warning lamp on the instrument panel.
The 12
V accessory battery 3 powers the
vehicle’s conventional electrical system. It is
recharged automatically by the traction battery
via the on-board charger.
The heat pump
4 provides passenger
compartment heating and regulates traction
battery and on-board charger cooling.
The on-board charger 5 manages the domestic
charging
(mode 2) and accelerated charging
(mode 3) of the traction battery as well as the
recharging of the 12
V accessory battery.
The electric motor
6 provides propulsion in
accordance with the selected driving mode and
driving conditions. It recovers energy during
vehicle braking and deceleration
phases.

Dashboard instruments
1If a low oil level is confirmed by a check using
the dipstick, the level must be topped up to avoid
damage to the engine.
For more information on Checking levels, refer
to the corresponding section.
Oil gauge malfunction
This is indicated by the display of " OIL_ _"
or by the message "Oil level measurement
invalid " (depending on the instrument panel),
accompanied by the lighting of the Service
warning lamp and an audible signal.
Contact a CITROËN dealer or a qualified
workshop.
In the event of a malfunction of the
electric gauge, the oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located in the engine compartment.
For more information on Checking levels,
refer to the corresponding section.
Coolant temperature
indicator
Depending on the type of instrument panel, this
information is only available in the instrument
panel's personalisable area.


With the engine running:
– In zone A, the temperature is correct.
–

In zone
B, the temperature is too high. The
associated warning lamp and the STOP
warning
lamp light up in red on the instrument panel,
accompanied by the display of a message and
an audible signal.
You must stop the vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine.
After switching off the ignition, carefully open the bonnet and check the coolant
level.
For more information on Checking
levels, refer to the corresponding
section.
AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
When the level of AdBlue® falls below the
reserve level (between 1,500 and 0 miles (2,400
and 0

km)), a warning lamp lights up when
the ignition is switched on and an estimate
of the distance that can be travelled before
engine starting is prevented is displayed in the
instrument panel.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the
engine until the minimum level of AdBlue
® has
been topped up.
Manual display of driving range
While the driving range is greater than
1,500 miles (2,400 km), it is not displayed
automatically.

opened within 30 seconds of unlocking), the
monitoring system is automatically activated.
Locking the vehicle
with exterior perimeter
monitoring only
Deactivate the interior volumetric monitoring to
avoid the unwanted triggering of the alarm, in
certain cases such as:
–

Slightly open window

Lighting and visibility
4Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
obstruct the camera.
Automatic headlamp dipping
For more information, refer to the
General recommendations for
automatic lighting systems.
With the ring of the lighting control stalk in the
"AUTO" position and the function activated on
the touch screen, this system automatically
switches between dipped and main beam
headlamps, according to lighting and traffic
conditions, using a camera located at the top of
the windscreen.


This system is a driving aid. The driver remains responsible for
the vehicle's lighting, its correct use in the
prevailing light, visibility and traffic conditions,
and for compliance with driving and vehicle
regulations.
The system becomes operational when the vehicle exceeds 16 mph (25 km/h).
When the speed falls below 9 mph (15 km/h),
the function is no longer operational.
Activation/Deactivation
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The settings are changed via the Driving
touch screen menu.
With MyCitroën Drive
The settings are changed via the Vehicle
touch screen menu.
With MyCitroën Drive Plus
The settings are changed via the Settings > Vehicle touch screen
application.
The state of the system is stored when the
ignition is switched off.
When the system detects thick fog, it
temporarily deactivates the function.
Operation
If the ambient light level is very low and traffic
conditions permit:
– The main beam headla mps
come on automatically. These
indicator lamps light up on the instrument panel.
If the ambient light level is sufficient and/or the
traffic conditions do not allow the main beam
headlamps to be lit:
– The dipped beam head lamps
remain lit. These indicator lamps
light up on the instrument panel.

106
Driving
Malfunction
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
By default, the function is activated when the
ignition is switched on.
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The settings are changed via the Driving
touch screen menu.
With MyCitroën Drive
The settings are changed via the Vehicle
touch screen menu.
With MyCitroën Drive Plus
The settings are changed via the ADAS
touch screen application or via the
Shortcuts for driving aids .
The display of a message on the instrument
panel confirms the change of state.
If the function is deactivated while the engine is
in STOP mode, it will restart immediately.
Associated indicator lamps
Function activated: engine on standby
(STOP mode)
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.
