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.

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.

Automatic headlamp dipping
Switching on
System which automatically changes between dipped and main beam according to the lighting and traffic conditions, using a camera located in the rear view mirror.
Put the lighting control stalk ring in the "AUTO" position.
This automatic headlamp dipping system is a driving aid. The driver remains responsible for the vehicle's lighting, its correct use for the prevailing conditions of light, visibility and traffic and observation of driving and vehicle regulations.
Flash the headlamps (pull the stalk beyond the point of resistance) to activate the function. This indicator lamp comes on in the instrument panel to confirm activation.
Press the button, its indicator lamp comes on.
Switching off
Press the button, its indicator lamp goes off, the lighting system changes to "automatic illumination of headlamps" mode.
Pause
Flashing the headlamps again pauses the function and the lighting system changes to "automatic illumination of headlamps" mode.
Flash the headlamps again to reactivate the system.
Operation
Once activated, the system operates as follows: - if there is adequate light and/or if the traffic conditions do not allow the use of main beam, then dipped beam is maintained, - if the light level is low and the traffic
conditions allow, main beam comes on automatically. The system will be operational as soon as you have exceeded 15 mph (25 km/h). If the speed drops below 9 mph (15 km/h), the system no longer operates.
If the situation requires a change of headlamp beam, the driver can take over at any time.
Dynamic stability control (DSC) and anti-slip regulation (ASR)
Activation
These systems are activated automatically each time the vehicle is started. As soon as they detect a problem of grip or trajectory, these systems act on the operation if the engine and brakes.
This is indicated by flashing of this warning lamp in the instrument panel.
Deactivation
In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the DSC and ASR, so that the wheels can turn freely and regain grip.
Operating fault
Illumination of this warning lamp and the lamp in the deactivation button, accompanied by an audible signal and a message, indicate a fault with the system.
Reactivation
The systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h). Below 30 mph (50 km/h), you can reactivate them manually:
Press this button.
The indicator lamp in the button comes on. The DSC and ASR systems no longer act on the operation of the engine and on the brakes in the event of a involuntary change of trajectory.
Press this button again. Reactivate the systems as soon as the level of grip permits.
Contact a CITROËN dealer or a qualified workshop to have the system checked.
Main beam headlamps (xenon model)
Remove the protective plastic cover by pulling on the tab. Remove the connector with the bulb by pressing on the lug at the bottom. Remove the bulb and change it. For reassembly, carry out these operations in reverse order.
The headlamps are fitted with polycarbonate glass with a protective coating: do not clean them using a dr y or abrasive cloth, nor with a detergent or solvent product, use a sponge and soapy water or a pH neutral product, when using a high pressure washer on persistent marks, do not keep the lance directed towards the lamps or their edges for too long, so as not to damage their protective coating and seals.
Dipped beam headlamps (xenon model)
D1S xenon bulbs must be changed by a CITROËN dealer or a qualified workshop, as there is a risk of electrocution. It is recommended that the D1S bulbs are changed at the same time when one of them fails.
Changing a bulb should only be done after the headlamp has been switched off for a few minutes (risk of serious burns). Do not touch the bulb directly with your fingers, use a lint-free cloth. It is imperative to use only anti-ultraviolet (UV) type bulbs to avoid damaging the headlamp. Always replace a failed bulb with a new bulb with the same type and specification.
