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.

Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
Optimise your use of the gearbox
With a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
With an automatic gearbox, favour automatic
mode. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift indicator prompts you to engage
the most suitable gear. Whenever this indication
is displayed on the instrument panel, follow it
straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of electrical equipment
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31
mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help keep
the temperature in the passenger compartment
down (e.g.
sunroof blind, window blinds).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat as soon as possible.
Adapt your use of the headlamps and/or
foglamps to the level of visibility, in accordance
with current legislation in the country in which
you are driving.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving.
As a passenger, avoid connecting your
multimedia devices (e.g.
film, music, video
game) to help reduce the consumption of energy.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle. Place the
heaviest items in the boot as close as possible to
the rear seats. Limit the loads carried in the vehicle and
minimise wind resistance (e.g.
roof bars, roof
rack, bicycle carrier, trailer). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Comply with the servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
–

before a long journey
.
–

at each change of season.
–


after a long period out of use.
Do not forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
has a fault, your vehicle will emit pollution. Visit
a CITROËN dealer or a qualified workshop
as soon as possible to restore your vehicle's
nitrogen oxide emissions to legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).

Eco-driving
Optimising the driving range (Electric)
The vehicle’s electrical consumption depends
heavily on the route, the vehicle speed and your
driving style.
Try to remain in the "ECO" zone on the power
indicator, by driving smoothly and maintaining a
steady speed.
Anticipate the need to slow down, and brake
smoothly, whenever possible using engine
braking with the regenerative braking function,
which will move the power indicator into the
"CHARGE" zone.
Use the air conditioning rather than the heating
to demist the passenger compartment.

23
Dashboard instruments
1control fault: starting prevented in X miles
(kms) "), indicating the driving range in miles or
kilometres.
While driving, the message is displayed every 30
seconds. The alert is repeated when switching
on the ignition.
You can continue driving for up to 685 miles
(1,100
km) before the engine starting
prevention system is triggered.
Have it checked by a CITROËN dealer or
a qualified workshop.
Starting prevented
Every time the ignition is switched on, the
message "Emissions control fault: Starting
prevented" is displayed.
To restart the engine
Contact a CITROËN dealer or a qualified
workshop.
Power indicator (Electric)

CHARGE
Traction battery charging during deceleration
and braking.
ECO
Moderate energy consumption and optimised
driving range.
POWER
Energy consumption by the drive train during
acceleration.
Charge level indicator
(Electric)


The traction battery's actual charge level and
the remaining range are displayed continuously
when the vehicle is started.
With the ignition off, opening the driver's
door activates the indicator.
Associated warning lamps
Two successive alert levels indicate that the
energy available has dropped to a low level:
1st level: Reserve
The state of charge of the traction battery is low.
Fixed, accompanied by an audible signal.
►

V

iew the remaining range on the instrument
panel.
►

Put the vehicle on charge as soon as
possible.
2nd level: Critical
The state of charge of the traction battery is critical.
Fixed, together with the reserve warning lamp,
accompanied by an audible signal.
►

Y

ou must put the vehicle on charge.
The remaining range is no longer calculated. The drive train power
gradually decreases.
The heating and air conditioning are switched
off (even if the thermal comfort consumption
indicator is not at the "ECO" level).
Flow indicator (Electric)
The flow indicator displays the energy flows in
the vehicle in real time.
With MyCitroën Play or MyCitroën Drive
It is available in the " Personal 1"/"Personal 2"
display modes of the instrument panel.

24
Dashboard instruments
With MyCitroën Drive Plus

The indicator changes colour depending on how
energy from the traction battery is being used:
–
Blue: energy consumption.
–


Green: energy recovery
.
This indicator does not represent the battery's actual level of charge.
Thermal comfort
consumption indicator
(Electric)
(Depending on version)
It is available in the display pages of the
instrument panel.


The gauge shows the consumption of the
traction battery's electrical energy by the thermal
comfort devices in the passenger compartment.
The devices in question are the heating and air
conditioning systems.
This equipment can be used:
–

If the vehicle is not plugged in, when the
READY

lamp is lit.
–

If the vehicle is plugged in, when the ignition is
switched on ("Lounge" mode).
Selecting ECO

mode limits the performance of
some of this equipment. The thermal comfort
consumption indicator then moves into the
"ECO" zone.
To quickly heat or cool the passenger compartment, feel free to temporarily
select the maximum heating or cooling
setting.
When the heating is on maximum, the gauge
on the thermal comfort consumption indicator
is in the MAX zone. When the air conditioning
is on maximum, it stays in the ECO zone.
Excessive use of thermal comfort equipment,
particularly at low speed, can significantly
decrease the vehicle's range.
Remember to optimise equipment settings
upon achieving the desired level of comfort,
and adjust them if necessary whenever you
start the vehicle.
After an extended period without using the
heating, you may notice a slight odour during
the first few minutes of use.
