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.
1. HDi Diesel engine (driving the front wheel).
2. Electric motor (driving the rear wheels). 3. 200 V high voltage battery. 4. Electronic power supervisor.
5. Alternator-starter motor (Stop & Start).
6. Electronic gearbox (ETG6). 7. Electrical flow. 8. Mode selector.

The electronic power super visor (4) manages the operation of the two power units, HDi Diesel and electric, giving priority to low fuel consumption.
The alternator-star ter motor (5) assures the Stop & Star t 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.
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 per formance, - 4WD (4 Wheel Drive) mode, which improves traction at low speed when grip is poor (snow, mud, sand...).

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 motor 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.

AUTO mode
This mode is designed to optimise the vehicle's fuel consumption by managing the alternate or simultaneous operation of the two motors according to the conditions and driving style. When conditions allow, an adequate battery state of charge and moderate acceleration, the alternator-starter motor stops the HDi Diesel engine to provide 100% electric running.
Z E V m o d e
(all electric)
Zero emissions vehicle operation is assured 100 % by electric drive. This mode allows silent and clean running at moderate speeds.
If the conditions do not allow ZEV mode to be selected or maintained, the message " Electric mode is not currently available " appears in the screen. The ZEV indicator lamp flashes for a few seconds then goes off and the indicator lamp in the AUTO position comes on. In ZEV mode: - range and acceleration capacity are limited; the maximum speed is around 36 mph (60 km/h), - under high load or a priority requirement causing the start of the HDi Diesel engine, the system changes automatically to AUTOmode.
For more information on the special conditions for the operation of ZEVmode, refer to the corresponding section.
It can be activated when the conditions allow, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).
In AUTO mode, the electric motor : - can power the vehicle on its own in "zero emissions" electric running, depending on the state of charge of the battery, if the conditions specific to the vehicle are met
and if acceleration is moderate, - supplements the HDi Diesel engine when moving off and changing gear, during acceleration or when traction from the front wheels is inadequate, temporarily providing 4-wheel drive. The electric motor can operate only at speeds below 52 mph (85 km/h). It is no longer active above 75 mph (120 km/h).
Refer to the special conditions for operation of ZEV mode.

200 V high voltage battery
The Ni-Mh (Nickel-Metal Hydride) technology used for the high voltage battery is suited to the frequent partial charging and discharging cycles related to the operation of a hybrid vehicle. The battery is installed close to the electric motor, below the boot trim, behind the storage well.
Charging
The battery recharges automatically while travelling. The battery is charged when the vehicle decelerates and when going downhill, the electric motor then becomes a generator and converts kinetic energy into electrical energy (except if the speed of the vehicle is above 70 mph (120 km/h)). This recovery allows the use of "free" energy. The battery may also be partially charged up to a level of 4 to 5 bars, using the alternator-starter motor (Stop & Start) of the HDi Diesel engine.
The battery charging time is very short.
To preserve the service life of the battery, the level of charge never falls below 20%, even if no bars are displayed on the gauge after ZEVrunning. Where the battery is close to maximum,
vehicle deceleration with your foot off the accelerator pedal will be at a lower level.
The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration or going downhill (free energy).
The battery is not recharged from a mains power supply.
Once it is discharged, following ZEV running or high load, the battery will reach its optimum
level of charge after around 10 minutes.

Access to the underbonnet
Recommendations
Before doing anything under the bonnet, you must switch off the ignition and verify that the RE ADY lamp in the RE ADY lamp in the RE ADYinstrument panel is off - risk of serious injury!
The alternator-starter motor of your HYbrid4 vehicle is also supplied at high voltage. If the vehicle ignition has not been switched off, there is a risk of the engine restarting at any time.
Always ensure that the ignition is switched off ( RE ADY lamp off) before RE ADY lamp off) before RE ADYopening the bonnet.
