Automatic restarting of the Diesel engine or ZEV mode NOT available
The internal combustion engine may restar t 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 causethe vehicle to come out of ZEV mode and the Diesel engine to restar t, the vehicleautomatically changes to AUTO mode.
Diffi cult weather conditions and circumstances
- If certain conditions or engine
temperature requirements make it necessary (such as an enginetemperature that is too low for the ambient conditions). - When the battery is close to maximum charge (for example: when goingdown a long hill), because enginerecovery being no longer possible, theinternal 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).
Your vehicle is fitted with the most effectiveemissions control systems, in par ticular theParticle Emissions Filter (PEF). At regular intervals 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
".
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 alreadystarted since the vehicle was last started). - If the high voltage battery is notsufficiently charged. A minimum of 4 bars in ZEV mode so as to ensure operation over a cer tain distance (in AUTO, electric operation is accessiblefor 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 maycontinue for some time after refuelling).- During regeneration of the par ticle emissions filter, which occurs
automatically for 5 to 10 minutes, approximately every 300 miles(500 kms) (or less in extended urban running).
Action by the driver
- Moving the gear selector to position M.
- Action on steering mounted controlpaddles to change gear.
- Sustained and sharp acceleration.
- Use of demisting.
- Use of air conditioning.

HYbrid4 frequently asked questions
ZEV (Zero Emissions Vehicle) mode
Question Answer
Wh
y 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.
Cer tain 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 par ticle emissions filter (PEF).
Why do I sometimes see an aler t message "Electric
mode not available: PEF regeneration in progress"?
This is an message relating to the regeneration of the par ticle 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 urbanuse) as temporarily the HDi engine will not stop and this message will be displayed at
inter vals 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 runningelectrically in Auto mode? The management o
f 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 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.
Wh
y is it that the system makes me come out of ZEV(Zero Emissions Vehicle) mode; it does not return toZEV automatically when the conditions allow? It is not intended to
give preference to ZEV running at any cost, as it is not always the mosteconomical mode.
So the system returns automatically to Auto mode.

Limit the causes of excess
consumption
Spread loads throughout the vehicle; placethe 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 inpreference.Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer tyres.
Observe the recommendations
on maintenance
Check the tyre pressures regularly, when cold, referring to the label in the door aper ture, driver's side.Carry out this check in par ticular:- before a long journey,- at each change of season,- after a long period out of use.
When refuelling, do not continue after the 3rdcut-off of the nozzle to avoid any overflow.
Have your vehicle ser viced regularly (engine oil, oil filter, air filter...) and obser ve the schedule of operations recommended by the
manufacturer.
At the wheel of your new vehicle, it is only after the first 1 800 miles (3 000 kilometres) that youwill see the fuel consumption settle down to aconsistent average.

Comfort
Heating and Ventilation
The air circulating in the passenger compar tment
is filtered and originates either from the outside
via the grille located at the base of the windscreen or from the inside in air recirculation mode.
Controls
The incoming air follows various routes
depending on the controls selected by
the driver, the
front passenger and rear passengers, according to the level of equipment.
The temperature control enables you to obtain
the level of comfor t required by mixing the air of
the various circuits.The air distribution control enables you toselect the air vents used in the passenger compar tment by the combined use of theassociated buttons.
The air flow control enables you to increase or reduce the speed of the ventilation fan.
These controls are grouped together on controlpanel Aon the centre console.
