Presentation of the Hybrid4 system
Thank you for choosing a DS5 Hybrid4; this
vehicle has characteristics that are different from conventional vehicles.
Study this handbook to learn about the specific hybrid functions and for more information, refer
to the "Hybrid System" section.

The H
ybrid4 technology allows two sources of energy to be associated in an effective manner:
the Diesel HDi engine, which drives the front
wheels and the electric motor, which drives the rear wheels.These two motors can operate alternately or simultaneously, according to the hybrid modeselected 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 slowspeed and low load. It also assists the Dieselengine when moving off, accelerating and changing gear.The battery that powers the electric motor is recharged during phases of deceleration andstores 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 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.

Anti-theft protection
Electronic engine immobiliser
The keys contain an electronic chip which hasa secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible. This electronic engine immobiliser locks the
engine management system a few minutes after the ignition is switched off and prevents
starting of the engine by anyone who does not have the key.
In the event of a malfunction, you are informed
by a message in the instrument panel screen.
In this case, your vehicle does not start; contacta CITROËN dealer as soon as possible.
Ignition on without starting
the engine
(accessory position)

With the electronic key in the reader or the
Keyless Entry and Star ting key inside the
vehicle, pressing the "START/STOP" button,
with no action on the pedals, allows the ignition
to be switched on and so activate the ancillary equipment.
)
Press the "START/STOP" button,
the instrument panel comes on but the engine does not star t.) Press the button again to switch
off the ignition and so allow the
vehicle to be locked.
If you use the accessory position for toolong, the system automatically goes intoeconomy mode to avoid the risk of a flatbattery.

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 "zeroemissions" electric running, dependingon the state of charge of the battery, if the conditions specific to the vehicle are met
and if acceleration is moderate,

- supplements the Diesel en
gine
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).
