PRESENTATION
The HYbrid4 technology allows two
sources of energy to be associated in
an effective manner: the Diesel HDi en-
gine, which drives the front wheels and
the electric motor, which drives the rear
wheels.
These two motors can operate alter-
nately or simultaneously, according to
the hybrid mode selected and the driv-
ing conditions.
The electric motor alone provides power
for the vehicle in "ZEV" (Zero Emissions
Vehicle) mode, and in "Auto" mode for
running at slow speed and low load. It
also assists the Diesel engine when
moving off, accelerating and changing
gear.
The battery that powers the electric motor
is recharged during phases of deceleration
and stores the energy for subsequent use.

Main parts of the HYbrid4 system
The HDi Diesel engine - 1
, located at the front, drives the front wheels and pro-
vides most of the power needed to drive the vehicle.
It is fi tted with the Stop & Start
system - 5
which recharges the batteries and pro-
vides additional power when needed (in 4x4 mode).
The 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 battery - 3
, provides a source of energy for the rear
electric motor.
Its charging rate is managed automatically by the vehicle during phases of decel-
eration.
It is located in a compartment in the boot, access to which is restricted to trained
service technicians.
The battery state of charge
is indicated by 8 horizontal or vertical bars (depending
on the screen).
The 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 supervisor - 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.
The inverter acts on the torque of the electric motor, by regulating the current com-
ing from the high voltage battery pack. Its operating range is between 150 and
270 volts.
The transformer converts the 200 V of the battery pack to 12 V, to power the
vehicle's ancillary systems.
The Stop & Start system - 5
allows the Diesel engine to be put into standby dur-
ing stops (traffi c lights, a stop, or in a traffi c jam, for example) or during phases of
running in all-electric mode.
The stopping and restarting of the Diesel engine is done in a way that is instanta-
neous and transparent for the driver.
The electronic gearbox - 6
provides, in automatic mode, signifi cant savings in
fuel consumption compared to a conventional manual gearbox, thanks to its elec-
tronic 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.

How to start your vehicle
- Ensure that the gear lever is in posi-
tion N
.
- Switch the ignition on by turning the
key to position 2
.
If the Diesel pre-heating warning
lamp comes on (ambient tempera-
ture below freezing), wait unit it goes
off before starting.
- Press fi rmly on the brake pedal, turn
the ignition key to position 3
to start
up the hybrid system, then release
the key.
- The instrument panel and the Ready
lamp come on. The power meter
needle sweeps through its travel in-
dicating that the hybrid system is
active, confi rmed by a message
;
the dial in the centre console is in AUTO
mode (default mode for starting).
- The hybrid system determines
whether it is necessary to start the
Diesel engine.
- With the brake still applied, move
the gear lever to position A
to go
forwards or R
(by lifting the lever
slightly) for reverse.
- Lift your foot off the brake pedal, you
can move off.
- The parking brake is released au-
tomatically as you move off, if con-
fi gured to do so (otherwise, release
the parking brake manually).
How to stop your vehicle andthe hybrid system
- Apply the brake until the vehicle
comes to a complete stop.
- Place the gear lever in position N
.
- Turn the ignition key to position 1
,
the parking brake is applied auto-
matically if confi gured to do so.
- Otherwise apply the parking brake
manually, the P
warning lamp must
be on.
For more information, refer to the
"Underbonnet precautions / warnings"
section. When stationary, switch off the
ignition and ensure that the
Ready
lamp is off before you
leave the vehicle, otherwise the
hybrid system will still be active.
When your vehicle starts in
electric mode, this means
that it makes no noise. Be
very careful of pedestrians
as they will not hear you coming.

ZEV mode * (all electric)
Zero emissions vehicle operation is as-
sured 100 % by electric drive.
This mode forces silent running
at
moderate speeds.
* ZEV: Zero Emissions Vehicle. In ZEV mode:
- The accelerator control is progressive.
- Range and acceleration capacity are
limited. The maximum speed pos-
sible is around 36 mph (60 km/h).
- Under high load or a priority require-
ment causing the start of the Diesel
engine, the system changes auto-
matically to AUTO mode.
It can be activated when
the required conditions are
met, particularly if the state
of charge of high voltage
battery is suffi cient (4 bars minimum).
If the conditions do not allow
this mode, a message that
the "electric mode is not cur-
rently available" appears in
the screen. The ZEV warning
lamp fl ashes for a few seconds then
goes off and the selector comes on in
AUTO.
Auto mode
It automatically manages the operation
of the Diesel engine and the electric
motor, according to inherent vehicle pa-
rameters, traffi c conditions and driving
style so as to optimise the vehicle's
fuel consumption
.
In particular, this mode activates "zero
emissions" electric running
when the
conditions 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, depend-
ing on the state of charge of the bat-
tery, if the conditions specifi c to the
vehicle are met and if acceleration is
moderate,
- supplements the Diesel engine
when moving off and changing gear,
during acceleration and when trac-
tion from the front wheels is inade-
quate (it automatically adds
4 wheel
drive
),
- is no longer active above 70 mph
(120 km/h).
This standard
mode to use in
preference
is activated auto-
matically
on starting the hy-
brid system.
For more information on "Au-
tomatic restarting of the Diesel
engine or ZEV mode not avail-
able", refer to the corresponding
section.

Sport mode (Diesel and electric)
4WD 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.
This mode manages the progressiveness
of the accelerator, the electronic gearbox
and the use of the electric motor.
In Sport mode:
- The electric motor can be used up to
70 mph (120 km/h).
This mode provides additional trac-
tion
*** 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) op-
erate simultaneously and permanently.
Their coupling is managed electroni-
cally to optimise traction on slippery
surfaces.
In 4WD mode:
- Power for the electric motor is pro-
vided, if needed, by the alternator-
starter motor of the front engine.
The Diesel engine operates continu-
ously.
- The additional traction from the elec-
tric motor is available up to 75 mph
(120 km/h).
This mode should be used on
snow covered roads or diffi cult
ground (mud, sand, ...).
In this mode, in severe conditions
and if the circumstances allow, it is
recommended that you accelerate
strongly to ensure that you move off
and avoid any risk of getting stuck.
** 4WD: 4 Wheel Drive.
***
This mode will be even more effec-
tive if suitable tyres are fi tted (winter
tyres in particular).

ENERGY CONSUMPTION / GENERATION INDICATOR
The indicator dial provides real time information on the total power used, combin-
ing electric and Diesel.
It comprises three main zones.
ECO zone
POWER zone
CHARGE zone
Zone which indicates that the vehicle is
in electrical energy recovery
phase: on
deceleration, braking or foot off the ac-
celerator, ...
This allows the high voltage battery
to be recharged using "free" energy
which can then be reused
for future en-
ergy requirements.
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 suit-
able driving style (smooth "eco-citizen"
driving). Zone which indicates that the vehicle
is optimising its energy consump-
tion
, electric, Diesel or a combination
of both. Zone which indicates an increased cumu-
lative power demand
from your hybrid
vehicle, taking account of the combined
capacities of the Diesel engine and the
electric motor.
