Energy consumption / generation indicator
The indicator dial provides real time information
on the total power used, combining electric and
Di
esel.
It comprises three main zones.
CHARGE zone
Zone which indicates that the vehicle isin electrical energy recovery
phase:
on deceleration, braking or foot off the
accelerator, ...
This allows the high voltage battery to be recharged using "free" energy
which can thenbe reusedfor future energy requirements.
POWER zone
Zone which indicates an increased cumulative power demand
from your hybrid vehicle,
taking account of the combined capacities of
the Diesel engine and the electric motor.
Z
one which indicates that the vehicle is
optimising its energy consumption, electric,
Diesel or a combination of both.
This zone corresponds to phases of electric
running as well as to phases of optimum use of
the Diesel engine, which are easily accessible
with a suitable driving style (smooth "eco-citizen" driving).

Examples of displays
On starting and when stationary
There is no flow of energy (the Stop & Star t system stops and restar ts the Diesel engine automatically).
Energy recovery
During this phase (deceleration, braking, foot off the accelerator, … all modes), the battery is recharged by the electric motor/generator,
then being driven by the rear wheels.
You can maximise this ener
gy recovery by taking your foot off
the accelerator pedal, deceleration will then be less marked than
with
a conventional vehicle.
100% electric
In all electric running (AUTO or ZEV modes), only the electricmotor, powered by the battery, drives the rear wheels.
The display of "Zero Emission" indicates that the Diesel engine
is off and the vehicle is producing no CO2.

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.
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 isaccessible for a shor ter period witha 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.

After switching off the ignition, the vehicle

Durin
g electric running and when the engine is

However, variations in temperature may still be felt in very hot climates. To avoid anydiscomfort in these conditions you can operate
the E

Eco-driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
Optimise the use of your
gearbox
Use automated mode Aas much as possible as this optimises gear changes to suit the
circumstances.
Drive smoothly
Maintain a safe distance between vehicles, use engine braking rather than the brake pedal, and press the accelerator progressively. These practices contribute towards a reduction in fuel consumption and CO2 emissions and also helps reduce thebackground traffic noise.
If your vehicle has cruise control, make use of the system at speeds above 25 mph (40 km/h) when the traffic is flowing well.
Control the use of your
electrical equipment
Before moving off, if the passenger compartment is too warm, ventilate it byopening the windows and air vents before using the air conditioning.
Above 30 mph (50 km/h), close the windowsand leave the air vents open. Remember to make use of equipment that canhelp 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 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.

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 andreduce wind resistance (roof bars, roof rack,bicycle carrier, trailer...). Use a roof box in preference.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.
Have your vehicle ser viced regularly (engine oil, oil filter, air filter...) and obser ve the schedule of operations recommended by the
manufacturer.
When refuelling, do not continue after the3 rd
cut-off of the nozzle to avoid any overflow.
At the wheel of your new vehicle, it is onlyafter the first 1 800 miles (3 000 kilometres) that you will see the fuel consumption settle down to a consistent average.

Resetting the history
With the hybrid system active, when trip 2displayed, press the control for 2 seconds to
reset the history to zero.
For more information on the trip computer, refer to the corresponding section. "60 % H
ybrid Use" corresponds to 60 % of the cumulative running time of the electric motor in the various Modes (Auto,
ZEV, Sport or 4WD) and 40 % of the time with the Dieselengine only (with no contribution from the hybrid system).
