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 star ted since the vehicle was last star ted).
- If the high voltage battery is not sufficiently charged. A minimum of 4 barsin ZEV mode so as to ensure operationover a cer tain distance (in AUTO, electricoperation is accessible for a shor ter period with a lower level of charge).
- When the fuel level enters the reservezone (where rate of consumption of this reser ve is high, ZEV inhibition may continue for some time after refuelling).
- During regeneration of the particleemissions filter, which occursautomatically for 5 to 10 minutes,approximately every 300 miles (500 kms)(or less in extended urban running).
The internal combustion engine may restar t or
ZEV mode may not be available in the variousconditions presented below. The internal combustion engine can beswitched off automatically as soon as these
conditions are lifted. When the conditions described below causethe vehicle to come out of ZEV mode andthe Diesel engine to restar t, the vehicle automatically changes to AUTO mode.
Your vehicle is fitted with the most effective emissions control systems, in par ticular the Particle Emissions Filter (PEF).
At regular inter vals your Diesel engine will produce energy for the self-cleaning of this filter.During this PEF regeneration phase, electric running is purposely made unavailable andis accompanied by a message "Electricmode not available: PEF regeneration inprogress
".
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 cer tain 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 maximumcharge (for example: when going down a long hill), because engine recoverybeing no longer possible, the internalcombustion engine restar ts automatically just to provide engine braking.
- If the vehicle encounters a steep slope(car park ramp, ...).
- If the vehicle has been parked in the sunfor a prolonged period.
- When driving in mountainous conditions(altitude).

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 hassufficient charge, such as, for example, very cold conditions, altitude, demisting, high demand for heating or air conditioning, regeneration of the par ticle emissions filter (PEF).
Wh
y do I sometimes see an aler t message "Electric mode not available: PEF regeneration
in progress"? This is an messa
ge relating to the regeneration of the par ticle emissions filter (PEF). This is acompletely 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.
Wh
y is it not possible for me to put the vehicle
into ZEV mode, even though I had just beenrunning electrically in Auto mode? The mana
gement 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.
Wh
y is the range in ZEV (Zero Emissions
Vehic le) 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 o
f
ZEV (Zero Emissions Vehicle) mode; it does notreturn to ZEV automatically when the conditions allow? It is not intended to give pre
ference 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 thisoptimises gear changes to suit the circumstances, and the AUTOmode of theHybrid4 mode selector.When moving off, accelerate normally up tothe desired speed ( POWER
zone between20 and 40 %). At steady speeds, drive gently with smallmovements of the accelerator pedal (ECOor CHARGEzone), run in electric mode as oftenas possible when driving at low speed. Anticipate the need to slow down and useengine 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 byopening the windows and air vents beforeusing the air conditioning.
Above 30 mph (50 km/h), close the windowsand leave the air vents open. Remember to make use of equipment that can help keep the temperature in the passenger compar tment down (sun roof andwindow 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 defrostingcontrols, if not automatic.Switch off the heated seat as soon as possible.
Switch off the headlamps and front foglampswhen the level of light does not require their use.
Avoid running the Diesel engine when stationary, par ticularly in winter; your vehiclewill warm up much faster while driving.
As a passenger, if you avoid connecting your multimedia devices (film, music, video game...), you will contribute towards limitingthe consumption of electrical energy, and soof fuel.
Disconnect your por table devices beforeleaving the vehicle.
