The electronic power super visor (4)
manages the operation of the two power units,
HDi Diesel and electric, giving priority to low
fuel consumption.
The alternator-star ter motor (5)
assures
the Stop & Start
function, which allows the
HDi Diesel engine to be put into standby when
the vehicle is at a standstill (traffic lights, a
stop, or in a traffic jam...) or during phases of
running in 100% electric mode.
The stopping and restarting of the HDi Diesel
engine is done automatically and instantly
without any action on the part of the driver.
This alternator-starter motor also provides
additional charging of the high-voltage battery
by the HDi Diesel engine, if this not sufficiently
charged, or in 4WD
mode for example.
The 12 V batter y
, located under the bonnet,
powers the vehicle's conventional electrical
system. It is used for starting the HDi Diesel
engine and the operation of the vehicle's
equipment, such as the lighting, wipers, audio
system...
This 12 V battery is recharged automatically by
the high voltage network.

7Hybrid4 system
Compared to a manual gearbox, the ETG6
electronic gearbox (6)
provides, in automatic
mode, significant savings in fuel consumption,
through the electronic management of gear
changes.
The mode selector (8)
allows selection of the
four operating modes offered by the Hybrid4
system:
- AUTO
mode, which optimises fuel
consumption by automatically managing
the alternate or simultaneous use of the
two motors,
- ZEV
(Zero Emissions Vehicle) mode, which
provides 100% electric drive, when the
driving conditions and the state of charge
of the battery permit,
- SPORT
mode, which provides more
dynamic driving with additional
performance,
- 4WD
(4 Wheel Drive) mode, which
improves traction at low speed when grip is
poor (snow, mud, sand...).

9Hybrid4 system
When the Hybrid4 system is
started, this indicator lamp
comes on to signal that the
vehicle is ready to move off.
Illumination of this indicator lamp is more or
less instant but may take a few seconds in
some cases (pre-heating the HDi Diesel engine
in cold weather or in energy economy mode...).
READY lamp
Never leave the Hybrid4 system on
when leaving the vehicle, or opening
the bonnet, refuelling...
Before leaving the vehicle, ensure that
the READY
lamp is off.
This allows the high voltage battery to be
recharged using "free" energy
which can then
be reused
for future energy requirements.
CHARGE zone
POWER zone
Indicates an increased cumulative power
demand
from your vehicle, taking account
of the combined power available from the
HDi Diesel engine and the electric motor.
Power indicator
The indicator dial displays information on the total power used in real time, combining electric and
Diesel.
It comprises three operating zones.
Indicates that the vehicle
is optimising its energy
consumption
, electric, Diesel
or a combination of both.
ECO zone
This zone corresponds to phases of electric
running as well as to phases of optimum use
of the HDi Diesel engine, which are easily
accessible with a suitable driving style (smooth
"eco-citizen" driving).
Indicates that the vehicle is in
an electrical energy recovery
phase: on deceleration, braking
(partially) or particularly with
your foot off the accelerator.

On starting and when stationary
There is no flow of energy; the Stop & Start alternator-starter
stops and restarts the HDi Diesel engine automatically,
whatever the operating mode selected.
Energy recovery
During this phase (deceleration, braking, foot off the
accelerator, … all modes), the high voltage battery is
recharged by the electric motor/generator, then being driven by
the rear wheels.
You can maximise this energy recovery by taking your foot off
the accelerator pedal; deceleration will be less marked than
with a conventional vehicle.
100% electric
In all electric running (AUTO or ZEV modes), only the electric
motor drives the vehicle, via the rear wheels, powered by the
high voltage battery.
The display of " Zero Emission
" indicates that the HDi Diesel
engine is stopped and the vehicle is producing no CO
2.

Starting the Hybrid4 system
Activation of the Hybrid4 system
On activation of the Hybrid4 system, the
instrument panel lights up, the power indicator
needle is placed at position " 0
". The steering
column automatically unlocks (perceptible
noise and movement of the steering column).
Depending on certain parameters, such as the
state of charge of the high voltage battery or
the ambient temperature, the Hybrid4 system
itself determines whether it is necessary to
start the HDi Diesel engine.
The mode selector is at the AUTO
position.
In wintry conditions with the
engine cold, the Diesel pre-
heating warning lamp can stay
on for a few seconds; wait until
it goes off before releasing the
brake pedal.
Starting - switching off the Hybrid4 system
Never leave children alone inside the
vehicle when the Hybrid4 system is
active.
)
Place the gear selector at position N
.
)
Insert the electronic key in the reader.
or
)
With Keyless Entry and Starting, simply
having the electronic key inside the vehicle
is sufficient.
)
Press the brake pedal firmly.
)
Make a single short press (about one
second) on the " START/STOP
" button.
)
Maintain pressure on the brake pedal until
the READY
lamp comes on, signalling
activation of the Hybrid4 system, confirmed
by an audible signal.
If the Hybrid4 system does not activate:
)
If N
is flashing in the instrument
panel, move the gear selector to
position A
then to position N
.
)
If the " Foot on the brake
" is
displayed, press the brake pedal
firmly.
The READY
lamp may come on after
a few seconds if there is a demand
for activation of the Hybrid4 system
after energy economy mode has been
entered.

Switching off the Hybrid4 system
)
Immobilise the vehicle.
)
Place the gear selector in position N
.
)
Make a short press (about one second) on
the " START/STOP
" button.
The Hybrid4 stops:
- the READY
lamp goes off,
- the steering column locks,
- the electric parking brake is applied
automatically, unless its automatic mode is
deactivated.
)
Check that the parking brake warning
lamps are on.
)
Remove the electronic key from the reader.
Before doing anything under the
bonnet, the Hybrid4 must be switched
off ( READY
lamp off) and the electric
parking brake must be applied.
Check that the READY
lamp is off
before leaving the vehicle.
Never leave the electronic key in the
vehicle in your absence.
For reasons of safety and theft protection,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it on
your person.
Switching the ignition on
With the electronic key in the reader or the
Keyless Entry and Starting key inside the
vehicle, pressing the " START/STOP
" button,
with no action on the brake pedal
, allows the
ignition to be switched on.
)
Press the " START/STOP
"
button, the instrument panel
comes on but the Hybrid4 system
does not start up.
With the ignition on, the system goes
into energy economy mode when
necessary to maintain the state of
charge of the battery.
)
Press this button again to switch off the
ignition and so allow the vehicle to be
locked.

19Hybrid4 system
Mode selector
The selector allows the driver to select one of the four operating modes offered by the Hybrid4
system.
)
Turn the dial to the right or left; the mode selected is confirmed by illumination of the
corresponding indicator lamp.
ZEV
mode: for 100% electric running.
SPORT
mode: to make use of the maximum
per formance of the vehicle.
4WD
mode: to force 4x4 drive in conditions of
poor grip.
AUTO
mode: for everyday use and optimised
fuel consumption.
By default, the selector is in the AUTO
position when starting the Hybrid4 system, whatever
position it was in when the ignition was switched off.
AUTO mode
This mode is designed to optimise the vehicle's
fuel consumption by managing the alternate
or simultaneous operation of the two motors
according to the conditions and driving style.
When conditions allow, an adequate battery
state of charge and moderate acceleration, the
alternator-starter motor stops the HDi Diesel
engine to provide 100% electric running.
