Presentation of the Hybrid4 system

The Hybrid4 technology associates two
sources of power: an HDi Diesel engine, which
drives the front wheels and an electric motor,
which drives the rear wheels.
These two motors can operate alternately
or simultaneously, according to the Hybrid4
operating 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 when running at
slow speed and under low load. The electric
motor also assists the HDi Diesel engine when
moving off, accelerating and changing gear.
The electric motor is powered by a high
voltage battery that is recharged during phases
of deceleration as well as, up to a certain
threshold, by the HDi Diesel engine.

2. Electric motor (driving the rear wheels).

Hybrid4 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.

The electric motor (2) , located at the rear
of the vehicle, drives the rear wheels on its
own, or supplements the HDi Diesel engine,
according to the Hybrid4 operating mode
selected.
This electric motor also manages the recovery
of energy, the charging of the batteries during
phases of deceleration of the vehicle. It is
active up to 70 mph (120 km/h).

The 200 V high voltage battery (3) , using Ni-
MH technology, stores and delivers the energy
needed for operation of the electric motor.
Its state of charge is managed automatically
by the electric motor during phases of
deceleration or by the HDi Diesel engine below
a certain threshold.
This high voltage battery is located in a special
compartment under the boot floor. Access
to it is strictly restricted to technicians at a
CITROËN dealer or a qualified workshop.

The state of charge of the high voltage battery
is represented graphically by bars.
See the "Display of energy flows" section.

Your Hybrid4 vehicle is fitted with effective
emissions control systems, including the
Particle Filter (FAP) .
During particle filter regeneration phases,
the HDi engine is called on to produce the
temperatures needed for combustion of the
particles.
Electric running is temporarily unavailable
and is accompanied by the display of a
message " Electric mode not available: FAP
regeneration in progress ".

The electronic power supervisor (4)
manages the operation of the two power units,
HDi Diesel and electric, giving priority to low
fuel consumption.

The alternator-starter 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 battery , 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.

Hybrid4 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...).

Hybrid4 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.
