–

Accelerated charging in mode 3 using an
accelerated charging unit (W

allbox).
–

Superfast charging in mode 4 using a fast
public charger

.
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
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.

regulation (ASR)
Fixed.
The system is deactivated.
The DSC/ASR system is reactivated
automatically when the vehicle is restarted,
and at speeds above approximately 31 mph
(50

km/h).
At speeds below 31
mph (50 km/h), it can be
reactivated manually.
Under-inflationFixed.
The pressure in one or more tyres is too
low.
Check the pressure of the tyres as soon as
possible.
Reinitialise the detection system after adjusting
the pressure.
Under-inflation warning lamp
flashing then fixed and Service
warning lamp fixed.
The tyre pressure monitoring system is faulty.
Under-inflation detection is no longer monitored. Check the tyre pressures as soon as possible
and carry out (3).
Engine pre-heating (Diesel)Temporarily on
(up to approximately 30 seconds in
severe weather conditions).
When switching on the ignition, if the weather
conditions and the engine temperature make it
necessary.
Wait until the warning lamp goes off before
starting.
When the warning lamp goes off, starting will
occur immediately if you press and hold:
–

the clutch pedal with a manual gearbox.
–


the brake pedal with an automatic gearbox.
If the engine does not start, make the engine
starting request again, while keeping your foot
on the pedal.
Particle filter (Diesel)Fixed, accompanied by an audible signal
and a message about the risk of particle
filter blockage.
The particle filter is nearing saturation.
As soon as traffic conditions permit, regenerate
the filter by driving at a speed of at least 37
mph
(60

km/h) until the warning lamp goes off.
Fuel filter (Diesel)Fixed.
The Diesel fuel filter contains water.
Carry out (2) without delay. Risk of damaging the
fuel injection system!
AirbagsFixed.
One of the airbags or seat belt
pyrotechnic pretensioners is faulty.
Carry out (3).
Front passenger airbag (ON)Fixed.
The front passenger airbag is activated.
The control is in the "ON" position.
In this case, do NOT install a "rearward
facing" child seat on the front passenger seat
- risk of serious injury!
Front passenger airbag (OFF)Fixed.
The front passenger airbag is deactivated.
The control is set to the “OFF ” position.
A "rearward facing" child seat can be installed,
unless there is a fault with the airbags (Airbags
warning lamp on).
Low fuel level (Petrol or Diesel)Fixed, with the reserve level shown in red,
accompanied by an audible signal and
the display of a message.
When it first comes on, you have approximately
6 litres of fuel remaining in the tank (reserve).
Until the fuel level is topped up, this alert will
be repeated every time the ignition is switched
on, with increasing frequency as the fuel level
decreases and approaches zero.
Refuel without delay to avoid running out of fuel.

Instruments
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.
It is available in the " Personal 1"/"Personal 2"
display modes of the instrument panel.
For more information on the Display modes,
refer to the corresponding section.


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 " Personal 1"/"Personal 2"
display modes of the instrument panel.
For more information on the Display modes,
refer to the corresponding section.


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.
Manual test
This function allows you to check certain
indicators and display the alerts log.
It can be accessed via the "Check" button
in the Driving/Vehicle touch screen
menu.
