5Hybrid4 system
DS5Hy4_en_Chap00c_hybride_ed01-2015
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 batter y (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 Par ticle 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 " .

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 RE ADY lamp is off. RE ADY lamp is off. RE ADY
better energy recovery). 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 recoveryphase: on deceleration, braking (partially or particularly with your foot off the accelerator, to use in preference as this gives

Hybrid4 modes
1. Hybrid4 mode selected ( AUTO , ZEV , ZEV , ZEVSPORT or 4WD ) . 2. "Zero Emission" messages if the HDi Diesel engine is stopped (0 g/km CO2) .
Display of fl ows in the touch screen tablet
Information on the hybrid mode selected ( 1, 2 ), arrows for energy flows ( 6 to 8 ) and the state of charge of the high voltage battery ( 4 ), is displayed in real time in the instrument panel screen or the the touch screen tablet. See the "Trip computer" section.

On starting and when stationary
There is no flow of energy; the Stop & Start alternator-starter stops and restarts the HDi Diesel engine automatically, whatever the operating mode selected.
Energy recovery
During this phase (deceleration, braking, foot off the accelerator, … all modes), the high voltage battery is recharged by the electric motor/generator, then being driven by the rear wheels. You can maximise this energy recovery by taking your foot off the accelerator pedal; deceleration will be less marked than with a conventional vehicle.
100% electric
In all electric running (AUTO or ZEV modes), only the electric ZEV modes), only the electric ZEVmotor drives the vehicle, via the rear wheels, powered by the high voltage battery. The display of " Zero Emission " indicates that the HDi Diesel engine is stopped and the vehicle is producing no CO2.

Starting the Hybrid4
system
Activation of the Hybrid4 system
On activation of the Hybrid4 system, the instrument panel lights up, the power indicator needle is placed at position " 0 ". The steering column automatically unlocks (perceptible noise and movement of the steering column). Depending on certain parameters, such as the state of charge of the high voltage battery or the ambient temperature, the Hybrid4 system itself determines whether it is necessary to start the HDi Diesel engine. The mode selector is at the AUTO p o s i t i o n .
In wintry conditions with the engine cold, the Diesel pre-heating warning lamp can stay on for a few seconds; wait until it goes off before releasing the brake pedal.
Starting - switching off the Hybrid4 system
Never leave children alone inside the vehicle when the Hybrid4 system is a c t i v e .
 Place the gear selector at position N .  Insert the electronic key in the reader. or  With Keyless Entry and Starting, simply having the electronic key inside the vehicle is sufficient.
 Press the brake pedal firmly.  Make a single short press (about one second) on the " START/STOP " button.  Maintain pressure on the brake pedal until the RE ADY lamp comes on, signalling RE ADY lamp comes on, signalling RE ADYactivation of the Hybrid4 system, confirmed by an audible signal.
If the Hybrid4 system does not start up:  If N is flashing in the instrument panel, move the gear selector to position A then to position N .  If the " Foot on the brake " is displayed, press the brake pedal
f i r m l y .

Moving off
For more information on the ETG6 electronic gearbox and the electric parking brake, refer to the corresponding sections in the handbook for the vehicle.
You can change the operating mode of the Hybrid4 system at any time using its mode selector. Driving in ZEV mode requires that particular conditions be met.
When your vehicle vehicle moves off in electric mode, it makes no noise. Be very careful of pedestrians, cyclists... as, because of this, they will not hear you coming.
Head-up display
The colour of the speedometer varies according to the drive train used: - white display: Diesel engine running, - blue display: Diesel engine s t o p p e d .
Using automatic mode with the electronic gearbox optimises gear changes and so gives more economical driving.
 If automatic operation of the electric parking brake has been deactivated, pull the control lever to release the parking brake manually.  Progressively release the brake pedal. If the parking brake is released, the vehicle then moves off. If the parking brake is still applied and is in automatic mode, accelerate progressively.
 Move the gear selector to position A(automatic mode) or M (manual mode) or R ( r e v e r s e ) .

Switching off the Hybrid4
system
 Immobilise the vehicle.  Place the gear selector in position N .  Make a short press (about one second) on the " START/STOP " button. The Hybrid4 stops: - the RE ADY lamp goes off, RE ADY lamp goes off, RE ADY
- the steering column locks, - the electric parking brake is applied automatically, unless its automatic mode is deactivated.  Check that the parking brake warning lamps are on.  Remove the electronic key from the reader.
Before doing anything under the bonnet, the Hybrid4 must be switched off ( RE ADY lamp off) and the electric RE ADY lamp off) and the electric RE ADYparking brake must be applied.
Check that the RE ADY lamp is off RE ADY lamp is off RE ADYbefore leaving the vehicle. Never leave the electronic key in the vehicle in your absence.
For reasons of safety and theft protection,
do not leave your electronic key in the vehicle, even when you are close to it. It is recommended that you keep it on your person.
Switching the ignition on
With the electronic key in the reader or the Keyless Entry and Starting key inside the vehicle, pressing the " START/STOP " button, with no action on the brake pedal , allows the ignition to be switched on.
 Press the " START/STOP " button, the instrument panel comes on but the Hybrid4 system does not start up.
With the ignition on, the system goes into energy economy mode when necessary to maintain the state of charge of the battery.
 Press this button again to switch off the ignition and so allow the vehicle to be l o c k e d .
