Main parts of the HYbrid4 system
the HDi Diesel engine - 1, located at the front, drives the front wheels and provides most of the
power needed to drive the vehicle.
It is fitted with an alternator-starter motor (Stop & Star t ) - 5 which recharges the batteries and
provides additional power when needed (in 4x4 mode).
th

e electric motor - 2 , located at the rear, drives the rear wheels on its own, or supplements the
Diesel engine, according to the hybrid mode selected.
It recovers energy and charges the batteries during phases of deceleration of the vehicle and is
active up to 70 mph (120 km/h).
A 200 V NI-MH high voltage batter y - 3 , provides a source of energy for the rear electric motor.
Its charging rate is managed automatically by the vehicle during phases of deceleration.
It is located in a compartment in the boot, access to which is restricted to trained service
technicians.
th

e battery state of charge is indicated by 8 horizontal or vertical bars (depending on the screen).
th

e conventional battery , located under the bonnet, powers the vehicle's 12 V systems. It is
recharged automatically by the high voltage network.

the electronic power super visor - 4 automatically manages the operation of the two power units
(Diesel and electric) to provide the lowest consumption.
An inverter and a transformer are needed to manage the electric power.
th
e inverter acts on the torque of the electric motor, by regulating the current coming from the high
voltage battery pack. Its operating range is between 150 and 270 volts.
th

e transformer converts the 200 V of the battery pack to 12 V, to power the vehicle's ancillary
systems.
th

e alternator-starter motor - 5 assures the Stop & Star t function which allows the Diesel
engine to be put into standby during stops (traffic lights, a stop, or in a traffic jam, for example) or
during phases of running in all-electric mode.
th

e stopping and restarting of the Diesel engine is done in a way that is instantaneous and
transparent for the driver.
It also provides additional charging of the batteries (4x4 mode for example or under-charged high
voltage battery).
th

e electronic gearbox - 6 provides, in automatic mode, significant savings in fuel consumption
compared to a conventional manual gearbox, thanks to its electronic control system.
It also offers improved driving pleasure with the possibility at any time of choosing the gear
changing mode: automatic or manual, using the paddles located behind the steering wheel.

"SPORT" mode
(Diesel and
electric)
this mode allows more dynamic driving by
providing additional performance.
Vehicle acceleration and pick-up are
maximised by using the capacity of the electric
motor, supplementing the power of the Diesel
engine.
th

is mode manages the response of the
accelerator, the electronic gearbox and the use
of the electric motor.
In "SPOR
t" m

ode:
-
t
h
e electric motor can be used up to
75 mph (120 km/h).
"4WD" mode*
(Diesel and
electric)
this mode provides additional traction ** at
low speed by driving all 4 wheels of the vehicle
continuously: the Diesel engine (front wheel
drive) and the electric motor (rear wheel drive)
operate simultaneously and permanently.
th

eir coupling is managed electronically to
optimise traction when grip is poor.
In 4WD mode:
-

P
ower for the electric motor is provided, if
necessary, by the alternator-starter motor
of the front engine.
t
h
e Diesel engine
operates continuously.
-
t
h
e additional traction from the electric
motor is available up to 75 mph (120 km/h).th is mode should be used on snow
covered roads or difficult ground
(mud, sand, ...).
In this mode, in severe conditions
and if the circumstances allow, it is
recommended that you accelerate
strongly to facilitate moving off and
reduce the risk of getting stuck.
th

e addition of "4WD" traction is
available whatever:
-

t
he state of charge of the traction
battery,
-

t
he altitude.
Be aware of the ground clearance of
your vehicle: around 184 mm (with the
vehicle in working order: driver only and
the fuel tank full) in ideal conditions.
th

is value will vary with vehicle load,
the nature of the ground sur face and
the surroundings.
If the driver considers that the vehicle
can traverse an obstacle, they assume
entire responsibility for this.
* "4WD": 4 Wheel Drive.
**
t
h
is mode will be even more effective if tyres
more suitable for the conditions are fitted
("winter" tyres in particular). When driving on flooded roads or when
crossing a ford, drive at walking pace.

200 V high voltage battery
the 200 V high voltage battery cannot be
recharged from a mains supply.
th
e battery is Ni-MH (Nickel Metal Hydride)
and is located below the boot floor, close to the
electric motor.
Charging
the battery is charged when the vehicle
decelerates, the electric motor then becomes
a generator and converts kinetic energy into
electrical energy (except if the speed of the
vehicle is above 70 mph (120
km/h)).
th

e battery is not recharged from a mains
supply.
th

e battery may also be charged automatically
when required by the alternator-starter motor
(Stop & Start) of the Diesel engine.
th
is recovery allows the use of "free" energy.
th

e battery charging time is very short and is
continuous.
A discharged battery (following Z
eV r
unning
or high load, for example) will quickly return to
a state of charge sufficient for full operation of
the different hybrid modes.
The charging takes place automatically
when driving .
th
e energy recovery can be faster during
deceleration.th e average state of charge is 4 to 5 bars, so
preserving a margin for energy recovery when
deceleration of going downhill (free energy).
to p

reserve the service life of the
battery, the level of charge never falls
below 20 %, even if a level of 0 bars is
displayed after Z
eV r

unning.
Where the battery is close to maximum,
vehicle deceleration with your foot
off the accelerator pedal will be at a
lower


level.

underbonnet precautions / warnings
Always ensure that the
ignition is switched off
(Ready lamp off) before
opening the bonnet.
Before doing anything under the
bonnet, to avoid the risk of serious
injury switch off the ignition and verify
that the Ready lamp in the dashboard
is of f.
Also ensure that the ignition is switched
off when refuelling to avoid the engine
restarting.
th

e alternator-starter motor of your hybrid
vehicle is also supplied at high voltage. If the
vehicle ignition has not been switched off, there
is a risk of the engine restarting at any time.
