Overview
– Domestic charging in mode 2 using a
domestic socket and associated charging cable
7
.
–

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.

indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.

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.
