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.

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 PEUGEOT 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.
The 12 V batter y , located under the bonnet, powers the vehicle's conventional electrical system. It 12 V batter y , located under the bonnet, powers the vehicle's conventional electrical system. It 12 V batter yis 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.
Your HYbrid4 vehicle is fitted with effective emissions control systems, including the Par ticle Filter (FA P) . 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 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...).

Power indicator
The indicator dial displays information on the total power used in real time, combining electric and Diesel. It comprises three operating zones.
CHARGE zone
Indicates that the vehicle is in an electrical energy recovery phase: on deceleration, braking (partially) or particularly with your foot off the accelerator.
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.
Indicates that the vehicle is optimising its energy consumption , electric, Diesel or a combination of both.

READY lamp
When the HYbrid4 system is started, this indicator lamp comes on to signal that the vehicle is ready to move off.
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
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...).
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).
This allows the high voltage battery to be recharged using "free" energy which can then be reused for future energy requirements.

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.

Fuel consumption histogram
(Only with touch screen)
This graph represents the history of average fuel consumption figures. It is accessible via the "Driving" menu of the touch screen.
These figures are calculated over the last 30 minutes in periods of 5 minutes.

 When trip "2" is displayed, press for more than 2 seconds on the end of the wiper control stalk to also reset the fuel consumption histogram.
For more information on the trip computer, refer to the corresponding section.
60 % Hybrid Use corresponds to 60 % of the cumulative running time with the addition of the HYbrid4 system and 40 % of the time with the Diesel engine only.
