PRESENTATION OF THE HYbrid4 SYSTEM
26
Thank you for choosing a 3008 HYbrid4;
this vehicle has characteristics that are
different from conventional vehicles.
Study this handbook to learn about the
specifi c hybrid functions and for more
information, refer to the "Hybrid System"
section.
The HYbrid4 technology allows two
sources of energy to be associated in an
effective manner: that of the Diesel HDi
engine which drives the front wheels and
that of 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 driving
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 mo-
tor recharges itself during phases of
deceleration and stores the energy for
subsequent use.

FAMILIARISATION
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
.
- The instrument panel and the Ready
lamp come on. The power meter
needle sweeps through its travel
indicating 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 auto-
matically as you move off, if confi gured
to do so (otherwise, release the park-
ing brake manually).
How to stop your vehicle
and the 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.
- Press fi rmly on the brake pedal, turn
the ignition key to position 3
to start
up the hybrid system, then release
the key.
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. See
"Underbonnet precautions/warnings".
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.

Displays according to version in the
instrument panel screen or the main
screen.
This mode allows a more dynamic driving
style providing increased performance.
Acceleration and pickup are maximised
using the full capacity of the electric motor
to supplement the Diesel engine.
The Stop & Start system also operates
in this mode.
This mode provides improved traction.
The Diesel engine drives the front
wheels continuously and the electric
motor drives the rear wheels.
Their coupling is managed automati-
cally to optimise traction on slippery
surfaces. This mode should be used on
snow covered roads and diffi cult ground
(mud, sand, …).

Main parts of the HYbrid4 system
The Diesel 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 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 deceleration.
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
coming 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 gear control gearbox 6
provides, in automatic mode, signifi cant
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.

How to start your vehicle
- Ensure that the gear lever is in
position N
.
- Switch the ignition on by turning the
key to position 2
.
- 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 nee-
dle sweeps through its travel indicat-
ing 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 auto-
matically as you move off, if confi g-
ured to do so (otherwise, release the
parking brake manually).
How to stop your vehicle and
the 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.
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.
When stationary, switch off
the ignition and ensure that
the Ready
lamp is off before
you leave the vehicle. Other-
wise the hybrid system will still be
active. See "Underbonnet precau-
tions/warnings".

Examples of displays
On starting and when stationary
there is no fl ow of energy (the Stop & Start system
stops and restarts the Diesel engine automatically).
Energy recovery
During this phase (deceleration, braking, foot off the
accelerator, … all modes), the battery is recharged by
the electric motor/generator, itself driven by the rear
wheels.
100 % electric
In all electric running (AUTO or ZEV modes), only the
electric motor, powered by the battery, drives the rear
wheels.
The display of "Zero Emissions" indicates that the
Diesel engine is off and the vehicle is producing no CO
