Automatic restarting of the Diesel engine or ZEV mode NOT available
Maintaining the performance of the system
- When the vehicle exceeds 18 mph (30 km/h) after moving off (if the internal
combustion engine has not already started since the vehicle was last started). - If the high voltage battery is not sufficiently charged. A minimum of 4 bars in ZEV mode so as to ensure operation over a certain distance (in AUTO, electric operation is accessible for a shorter period with a lower level of charge). - When the fuel level enters the reserve zone (where rate of consumption of this reserve is high, ZEV inhibition may continue for some time after refuelling). - During regeneration of the particle emissions filter, which occurs automatically for 5 to 10 minutes, approximately every 300 miles (500 kms) (or less in extended urban running).
The internal combustion engine may restart or ZEV mode may not be available in the various conditions presented below. The internal combustion engine can be switched off automatically as soon as these conditions are lifted. When the conditions described below cause the vehicle to come out of ZEV mode and the Diesel engine to restart, the vehicle automatically changes to AUTO mode.
Your vehicle is fitted with the most effective emissions control systems, in particular the Particle Emissions Filter (PEF). At regular intervals your Diesel engine will produce energy for the self-cleaning of this f i l t e r. During this PEF regeneration phase, electric running is purposely made unavailable and is accompanied by a message " Electric mode not available: PEF regeneration in progress ".
Action by the driver
- Moving the gear selector to position M . - Action on steering mounted control paddles to change gear. - Sustained and sharp acceleration. - Use of demisting. - Use of air conditioning.
Diffi cult weather conditions and circumstances
- If certain conditions or engine temperature requirements make it necessary (such as an engine temperature that is too low for the ambient conditions). - When the battery is close to maximum charge (for example: when going down a long hill), because engine recovery being no longer possible, the internal combustion engine restarts automatically just to provide engine braking. - If the vehicle encounters a steep slope (car park ramp, ...). - If the vehicle has been parked in the sun for a prolonged period. - When driving in mountainous conditions (altitude).

Hybrid4 frequently asked questions
ZEV (Zero Emissions Vehicle) mode
QuestionAnswer
Why is it not always possible for me to put the vehicle into ZEV (Zero Emissions Vehicle) mode even though the battery is well charged?
This situation is temporary. Certain conditions will occasionally prevent the change to ZEV mode, even if the battery has sufficient charge, such as, for example, very cold conditions, altitude, demisting, high demand for heating or air conditioning, regeneration of the particle emissions filter (PEF).
Why do I sometimes see an alert message "Electric mode not available: PEF regeneration in progress"?
This is an message relating to the regeneration of the particle emissions filter (PEF). This is a completely normal process that takes place every 240 or 300 miles (400 or 500 km) (or more frequently in prolonged urban use), as on a conventional HDi vehicle. This process is not generally noticed by the driver. On the other hand, in the case of a hybrid, this phenomenon may be noticeable (in urban use) as temporarily the HDi engine will not stop and this message will be displayed at intervals while regeneration is in progress.
Why is it not possible for me to put the vehicle into ZEV mode, even though I had just been running electrically in Auto mode?
The management of ZEV is different from Auto mode. Changing to ZEV mode is only possible with a battery charge of at least 4 bars, in order to assure sufficient range. In Auto mode, the system alone manages the conditions for changing temporarily to electric mode, for shorter periods and with a lower state of charge of the battery.
Why is the range in ZEV (Zero Emissions Vehicle) mode lower when climbing? The vehicle needs more energy when climbing than when running on the level. So it is better to stay in Auto mode, which will favour operation of the Diesel engine.
Why is it that the system makes me come out of ZEV (Zero Emissions Vehicle) mode; it does not return to ZEV automatically when the conditions
allow?
It is not intended to give preference to ZEV running at any cost, as it is not always the most economical mode. So the system returns automatically to Auto mode.

Air conditioning
QuestionAnswer
It seems to me that the vehicle runs less on electric when the heating or air conditioning is operating, is that right?
The demand for heating or air conditioning may require the starting of the Diesel engine until the desired level of comfort is attained. Normal hybrid operation is simply put back. The period can be longer under low or very high ambient temperatures.
It seems to me that when it is very hot and the air conditioning is working, the vehicle runs on electric for shorter periods. Is that right?
When it is hot, the periods when the Diesel engine is put on standby and the vehicle runs on electric are necessarily restricted in order to limit the difference between the temperature in the vehicle and the level of comfort selected. In very hot weather, it is always possible to press the Eco OFF button (which brings the vehicle out of ZEV mode and prevents electric running or the stopping of the engine) to give preference to temperature control (keeps the air conditioning running).
Special Hybrid4 features
QuestionAnswer
Can I tow with my hybrid vehicle and how much? A Hybrid4 vehicle can tow between 500 kg and 800 kg (see the "Towing" section). This allows a jet ski or two-wheeler on a trailer to be towed, for example. The "technical" reason for the limit is related to maintaining adequate cooling capacity for the internal combustion engine as well as the hybrid components that are also cooled by the engine's cooling system.
Why does engine braking seem so strong? When you take your foot off the accelerator, the engine braking results mainly from the energy recovery by the electric motor. This leads to a higher level of deceleration than a conventional vehicle and so allows the recovery of free energy.

ECO OFF switch
This function prevents the Diesel engine being switched off and so ensures that a comfortable temperature can be maintained in the passenger compartment (air conditioning running continuously). On pressing the switch, the engine restarts
immediately. To return to normal operation, press the switch again. After switching off the ignition, the vehicle will return to normal operation (lamp in the switch off).
* Except in ZEV mode, which favours electric
running over assuring a comfortable temperature.
During electric running and when the engine is stopped, the hybrid system manages restarting automatically to assure comfort levels in the passenger compartment * . However, variations in temperature may still be felt in very hot climates. To avoid any discomfort in these conditions you can operate the ECO OFF switch.

Eco-driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
Eco-driving suited to your
Hybrid4 vehicle
Use gear selector position A , as this optimises gear changes to suit the circumstances, and the AUTO mode of the Hybrid4 mode selector. When moving off, accelerate normally up to the desired speed ( POWER zone between 20 and 40 %). At steady speeds, drive gently with small movements of the accelerator pedal ( ECO or CHARGE zone), run in electric mode as often as possible when driving at low speed. Anticipate the need to slow down and use engine braking ( CHARGE zone), so as to make use of free energy recovery while keeping light pressure on the accelerator pedal.
Before moving off, if the passenger compartment is too warm, ventilate it by opening the windows and air vents before using the air conditioning. Above 30 mph (50 km/h), close the windows and leave the air vents open. Remember to make use of equipment that can help keep the temperature in the passenger compartment down (sun roof and window blinds...). Switch off the air conditioning, unless it has automatic digital regulation, as soon as the desired temperature is attained. Switch off the demisting and defrosting controls, if not automatic. Switch off the heated seat as soon as possible.
Switch off the headlamps and front foglamps when the level of light does not require their use.
Avoid running the Diesel engine when stationary, particularly in winter; your vehicle will warm up much faster while driving.
As a passenger, if you avoid connecting your multimedia devices (film, music, video game...), you will contribute towards limiting the consumption of electrical energy, and so of fuel. Disconnect your portable devices before leaving the vehicle.
Control the use of your electrical equipment

Observe the recommendations
on maintenance
Check the tyre pressures regularly, when cold, referring to the label in the door aperture, driver's side. Carry out this check in particular: - before a long journey, - at each change of season, - after a long period out of use.
Have your vehicle serviced regularly (engine oil, oil filter, air filter, passenger compartment filter...) and observe the schedule of operations recommended in the maintenance and warranty guide.
When refuelling, do not continue after the 3 rd cut-off of the nozzle to avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles (3 000 kilometres) that you will see the fuel consumption settle down to a consistent average.
At the end of winter, remove snow tyres and refit your summer tyres.
Spread loads throughout the vehicle; place the heaviest items in the bottom of the boot, as close as possible to the rear seats. Limit the loads carried in the vehicle and reduce wind resistance (roof bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference. Remove roof bars and roof racks after use.
Limit the causes of excess
consumption

49Hybrid system
Consumption of your hybrid in the screen
Average consumption over the last 5 minutes.
"60 % Hybrid Use" corresponds to 60 % of the cumulative running time with the addition of the hybrid system and 40 % of the time with the Diesel engine only (with no contribution from the hybrid system).
For more information on the trip computer, refer to the corresponding section.
Resetting the history
With the hybrid system active, when trip 2 displayed, press the control for 2 seconds to reset the history to zero.

200 V high voltage battery
The 200 V high voltage battery cannot be recharged from a mains supply. The battery is Ni-MH (Nickel Metal Hydride) and is located below the boot floor, close to the electric motor.
Charging
The battery is charged when the vehicle decelerates, 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)). The battery is not recharged from a mains supply. The battery may also be charged automatically when required by the alternator-starter motor (Stop & Start) of the Diesel engine.
This recovery allows the use of "free" energy. The battery charging time is very short and is continuous. A discharged battery (following ZEV running or high load, for example) will quickly return to a state of charge sufficient for full operation of the different hybrid modes. The charging takes place automatically when driving . The energy recovery can be faster during deceleration. The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration of going downhill (free energy).
To preserve the service life of the battery, the level of charge never falls below 20 %, even if a level of 0 bars is displayed after ZEV running. Where the battery is close to maximum, vehicle deceleration with your foot off the accelerator pedal will be at a lower level.

Underbonnet precautions / warnings
The alternator-starter motor of your hybrid 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 ( Ready lamp off) before opening the bonnet.
Before doing anything under the bonnet, to avoid the risk of serious injury switch off the ignition and verify that the Ready lamp in the dashboard is off. Also ensure that the ignition is switched off when refuelling to avoid the engine restarting.

Car washing machine or tunnel
Some car washing machines or tunnels (where the vehicle is moved for wards on a travelling track) require that the parking brake be "released" during the wash.
With the hybrid system active, Ready lamp on, parking brake released: - Place the gear selector in position N . - Switch off the engine (press on START/STOP). The parking brake is applied automatically and the Ready lamp goes off in the instrument panel. - Switch on the ignition again (press on START/STOP) without your foot on the brake pedal. The Ready lamp remains off. - Release the parking brake using the manual control on the centre console, while keeping your foot on the brake pedal. - Switch off the ignition (press on START/STOP without your foot on the brake pedal) checking that the parking brake
remains released.
If the Diesel engine is not running, it restarts. If the Diesel engine is running, it remains running without time limit.
With the hybrid system active, Ready lamp on, parking brake released: - Place the gear selector in position N (Auto or Sport mode). - Press the brake pedal then the ECO OFF button.
