39Hybrid system

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.

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.


100 % electric

In all electric running (AUTO or ZEV modes), only the electric motor, 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
- when maintaining a comfortabletemperature in the passenger compar tment (air conditioning, ...),- when using the vehicle after prolonged parking in a sunny area,- when demisting, - during sustained and sharp acceleration - in mountainous conditions (altitude), - when using the vehicle on a steep slope(car park ramp, ...),- when regenerating the par ticle emissionsfilter, for around 5 to 10 minutes every 300 miles (500 km) (or less for extended urban running. )- in certain engine temperature conditions or requirements, such as an enginetemperature that is too low for the ambientconditions. In ZEV mode, these conditions lead to animmediate change to AUTO mode.The Diesel engine is switched off automatically as soon as these conditions are lifted.
The main conditions are:


- if the gear lever is in position M,

- if the steering mounted gear change controlpaddles are operated,

- if the high voltage battery is not sufficientlycharged. At least 4 bars in ZEV mode soas to provide a cer tain distance (in AUTO mode, electric operation is available morebriefly with a lower state of charge),

- at 18 mph (30 km/h) after setting off (if the internal combustion engine has not already star ted since setting off),

- when the vehicle is on a slope, to retain engine braking from the internal combustion engine when the battery is fullycharged,

- when using engine braking from the internal combustion engine,

- when the fuel level enters the reserve zone(in the event of high consumption of this reser ve, inhibition of ZEV can continue for some time after refuelling).


Your vehicle is fitted with the most effectiveemissions control systems, in par ticular theParticle 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.

43Hybrid system








ECO OFF switch


This function prevents the Diesel engine
being switched off and so ensures that a comfor table temperature can be maintained in
the passenger compar tment (air conditioning
running continuously).
On pressing the switch, the engine restar ts
immediately.
To return to normal operation, press the switch
a
gain.
After switching off the ignition, the vehicle
will return to normal operation (lamp in
the switch off).

Eco-driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2emissions.
Optimise the use of your
gearbox
Use automatic 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
the background 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.


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 windows and leave the air vents open.
Remember to make use of equipment that canhelp keep the temperature in the passenger compartment down (sun roof and windowblinds...). Switch off the air conditioning, unless it has automatic digital regulation, as soon as thedesired 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 requiretheir use.

Avoid running the Diesel engine when stationary, par ticularly in winter; your vehicle will warm up much faster while driving.

As a passenger, if you avoid connecting your multimedia devices (film, music, videogame...), you will contribute towards limitingthe consumption of electrical energy, and soof fuel.
Disconnect your por table devices beforeleaving the vehicle.



Control the use of your electrical equipment

45
Hybrid system
Limit the causes of excess
consumption
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 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.

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 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 settledown to a consistent average.

Consumption of your hybrid in the screen

Average consumption over the last 5 minutes.
"60 % H
ybrid Use" corresponds to 60 % of the running
time driven by the hybrid system and 40 % of the time
with the Diesel engine only (with no contribution from thehybrid system).
