29Hybrid system
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 i
s fitted with the Stop & Start
system - 5which 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 hi
gh voltage battery - 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 compar tment in the boot, access to which is restricted to trained servicetechnicians.
The batter
y state of charge
is indicated
by 8 horizontal or vertical bars (depending on
the screen).

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

The electronic power super visor - 4automatically manages the operation of the twopower units (Diesel and electric) to provide the
lowest consumption.
An inverter and a transformer are needed to manage the electric power.
The inver ter acts on the torque of the electric
motor, by regulating the current coming from
the high voltage battery pack. Its operatingrange is between 150 and 270 volts.
The transformer converts the 200 V of thebattery pack to 12 V, to power the vehicle'sancillary systems.
The Stop & Start system - 5allows the Dieselengine 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.
The stopping and restar ting of the Diesel engine is done in a way that is instantaneous
and transparent for the driver.
The electronic gearbox - 6
provides, in
automatic mode, significant savings in fuelconsumption 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.

ZEV mode *
(all electric)

Zero emissions vehicle operation is assured10 0 % by electric drive.
This mode forces silent running
at moderate speeds.
It
can be activated when therequired conditions are met, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).


Auto mode
It automatically manages the operation of theDiesel engine and the electric motor, according
to inherent vehicle parameters, traffic conditions and driving style so as to optimise
the vehicle's fuel consumption.
In particular, this mode activates "zero emissions" electric runningwhen theconditions allow.
In auto mode, the electric motor:

- can drive the vehicle on its own up to
around 36 mph (60 km/h) in "zero emissions" electric running,
depending on the state of charge of the
battery, if the conditions specific to the
vehicle are met and if acceleration is
moderate, -supplements the Diesel engine when
moving off and changing gear, duringacceleration and when traction from the front wheels is inadequate (it automatically adds4 wheel drive),

- is no longer active above 70 mph(120 km / h).



*
ZEV: Z
ero Emissions Vehicle.
This standardmode to use in preference
is activated automaticallyon starting the hybrid system.

Energy consumption / generation indicator
The indicator dial provides real time information
on the total power used, combining electric and
Diesel.
It comprises three main zones. Zone which indicates that the vehicle is optimising its energy consumption
, electric,Diesel or a combination of both.
This zone corresponds to phases of electric running as well as to phases of optimum use of
the Diesel engine, which are easily accessible
with a suitable driving style (smooth "eco-citizen"
driving). Z
one which indicates that the vehicle is in electrical energy recoveryphase: on
deceleration, braking (partially or par ticularly
with your foot off the accelerator (to use
in preference as this gives better energy
recovery).
This allows the high voltage battery to be
recharged using "free" energy which can then be reused
for future energy requirements.

Automatic restarting of the Diesel engine or ZEV mode NOT available

Maintaining the performance
of the system



- When the vehicle exceeds 18 mph(30 km/h) after moving off (if the internal
combustion engine has not already star ted since the vehicle was last star ted).

- If the high voltage battery is not sufficiently charged. A minimum of 4 barsin ZEV mode so as to ensure operationover a cer tain distance (in AUTO, electricoperation is accessible for a shor ter period with a lower level of charge).

- When the fuel level enters the reservezone (where rate of consumption of this reser ve is high, ZEV inhibition may continue for some time after refuelling).

- During regeneration of the particleemissions filter, which occursautomatically for 5 to 10 minutes,approximately every 300 miles (500 kms)(or less in extended urban running).

The internal combustion engine may restar t or
ZEV mode may not be available in the variousconditions presented below. The internal combustion engine can beswitched off automatically as soon as these
conditions are lifted. When the conditions described below causethe vehicle to come out of ZEV mode andthe Diesel engine to restar t, the vehicle automatically changes to AUTO mode.
Your vehicle is fitted with the most effective emissions control systems, in par ticular the Particle Emissions Filter (PEF).
At regular inter vals your Diesel engine will produce energy for the self-cleaning of this filter.During this PEF regeneration phase, electric running is purposely made unavailable andis accompanied by a message "Electricmode not available: PEF regeneration inprogress
".
Action by the driver
- Moving the gear selector to position M
. - Action on steering mounted control paddles to change gear.- Sustained and sharp acceleration. - Use of demisting.- Use of air conditioning.


Diffi cult weather conditions and
circumstances



- If cer tain conditions or engine temperature requirements make it necessary (such as an engine temperature that is too low for the ambient conditions).

- When the battery is close to maximumcharge (for example: when going down a long hill), because engine recoverybeing no longer possible, the internalcombustion engine restar ts automatically just to provide engine braking.

- If the vehicle encounters a steep slope(car park ramp, ...).

- If the vehicle has been parked in the sunfor a prolonged period.

- When driving in mountainous conditions(altitude).

200 V high voltage battery
The 200 V high voltage battery cannot berecharged from a mains supply.
The 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 conver ts kinetic energy intoelectrical energy (except if the speed of the
vehicle is above 70 mph (120 km/h)).
The battery is not recharged from a mains
supply.
The battery may also be charged automatically
when required b
y the Stop & Start system of
the Diesel engine.
This recover
y allows the use of "free" energy.
The battery charging time is very shor t and iscontinuous.
A discharged battery (following ZEV running or high load, for example) will quickly return to astate of charge sufficient for full operation of the
different hybrid modes.
The charging takes place automaticallywhen driving.
The energy recovery can be faster during deceleration.
The average state of charge is 4 to 5 bars, sopreserving a margin for energy recovery when
deceleration of going downhill (free energy).
To preser ve the ser vice life of thebattery, the level of charge never fallsbelow 20 %, even if a level of 0 bars is displayed after ZEV running. Where the battery is close to maximum, vehicle deceleration with your foot off the accelerator pedal will be at a lower level.

51Hybrid system

This system does not work continuously,
but adapts the force of the fan cooling to the
requirements of the battery.
Its operation can be heard at the rear, even if
the vehicle is stopped after a run.
If the air intake is blocked, the battery mayoverheat, damaging the battery and causing a
loss of performance of the hybrid system.







Fan cooling of the high voltage battery


For the best use of the high voltagebattery, please follow these recommendations:


- do not obstruct the air intake withloose articles, otherwise, the battery may overheat, causing aloss of performance of the hybridsystem

- do not spill fluids, as this may cause damage to the battery.


The high voltage battery has an air cooling system, comprising an air intake(located on the side of the left hand rear seat) and a fan (located behind the lefthand boot trim panel).
