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.
1.Diesel HDi engine (front wheel drive).
2. Electric motor (rear wheel drive).3.
200 V battery.4.Electronic power supervisor.5
. Stop & Start system.
6.6 -speed electronic gearbox.
7. Electrical flow.
26
The Hybrid4 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 is fitted with the Stop & Start
system - 5
which 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 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 compar tment in the boot, access to which is restricted to trained ser vice
t
echnicians.
The batter
y state of chargeis indicated by 8 horizontal or vertical bars (depending on the screen).
Th
e conventional battery, located under the bonnet, powers the vehicle's 12 V systems. It is yrecharged automatically by the high voltage network.

The electronic power super visor - 4automatically manages the operation of the two power units(Diesel and electric) to provide the lowest consumption.
An inver ter 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 operating range is between 150 and 270 volts.
The transformer conver ts the 200 V of the battery pack to 12 V, to power the vehicle's ancillarysystems.
Th
e Stop & Start system - 5
allows the Diesel engine 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.
Th
e electronicgearbox - 6provides, in automatic mode, significant 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.

Anti-theft protection
Electronic engine immobiliser
The keys contain an electronic chip which hasa secret code. When the ignition is switchedon, this code must be recognised in order for
star ting to be possible.
This electronic en
gine 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.
Using the ancillaries for a long period introduces the risk of a flat battery.

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 (4 bars minimum).
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).
