For economical driving, caring for the environment


The fuel consumptionof a vehicle varies greatly:


- according to the driver's style of driving
(moderate, aggressive, fast, ...),

- accordin
g to the type of journeys
made (urban, main road, motor way, flowing, heavy traffic, …) and the speed.


Main recommendations for driving economically

Hybrid mode selector

To optimise fuel consumption, use the Automodeof the selector whenever possible (the mode is activated
automatically when starting) including for urban journeys.
This mode optimises the use of the energy sources (internal combustion engine and/or electric) contrary to other modes, which are for use in par ticular cases.


Gear lever
Use the automatic
mode A
as much as possible as this optimises gear changes to suit the requirements.


Causes of high consumption and checks
As with any vehicle, limit overloading, wind resistance (windows open above 30 mph (50 km/h), roof bars, loaded or not, …), the use of power consumers (air conditioning, heated seats, heated rear screen, …).
Obser ve the recommendations on checks (regular check of tyre pressures, correct tyre pressures, …) and routine servicing.



Drive smoothly
Stay in the "eco" zone
displayed in the energy consumption / generation indicator: accelerate gently, drive at steadyspeeds using the speed limiter or cruise control as soon as possible.Use the "charge" zone: anticipate the need to slow down by taking your foot off the accelerator rather than braking.
The movement of the energy consumption / generation indicator needle (into the "charge" zone), shows the level of energy recovery.

Consumption history
See the impact of your style of driving and the type of journey by reviewing the history of your energy consumption.Refer to the "Multifunction screens" section.

The electronic power super visor - 4automatically manages the operation of the twopower units (Diesel and electric) to provide the
lowest consumption.
An inverter and a transformer are needed to manage the electric power.
The inver ter acts on the torque of the electric
motor, by regulating the current coming from
the high voltage battery pack. Its operatingrange is between 150 and 270 volts.
The transformer converts the 200 V of thebattery pack to 12 V, to power the vehicle'sancillary systems.
The Stop & Start system - 5allows the Dieselengine to be put into standby during stops(traffic lights, a stop, or in a traffic jam, for example) or during phases of running in all-electric mode.
The stopping and restar ting of the Diesel engine is done in a way that is instantaneous
and transparent for the driver.
The electronic gearbox - 6
provides, in
automatic mode, significant savings in fuelconsumption compared to a conventional manual gearbox, thanks to its electronic control system.
It also offers improved driving pleasure with
the possibility at any time of choosing the gear changing mode: automatic or manual, using the paddles located behind the steering wheel.

Hybrid system








Hybrid4 mode selector
The selector allows the user to choose between 4 drive modes for the vehicle.
Turn the dial to the ri
ght or left; the mode selected is confirmed by illumination of the corresponding indicator.
ZEVmode, to force electric runnin
g.Spor
tmode, to make use of the maximum
performance of the vehicle.
4WDmode, to force the vehicle into 4x4 mode.

AUTOmode, for normal use and optimised fuelconsumption.

On star ting the vehicle: with the gear selector in position N, press the brake pedal and press
the STA R T/STOP button to activate the hybrid system.
This lamp comes on when the vehicle is ready
to move off ("Auto" mode is on by default) andso the driver can press the accelerator.
This lamp comes on more or less instantly but may take a few seconds in some cases (inparticular, the time needed for pre-heating the
Diesel engine in cold weather or, for example,
in energy economy mode, ...).








Ready lamp
With the vehicle stationary, press the STA R T/STOP button and check that the Readylamp is off when leaving thevehicle, other wise the hybrid system will still be active.


For more information, refer to the section on "Underbonnet precautions / warnings".

ZEV mode *
(all electric)

Zero emissions vehicle operation is assured10 0 % by electric drive.
This mode forces silent running
at moderate speeds.
It
can be activated when therequired conditions are met, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).


Auto mode
It automatically manages the operation of theDiesel engine and the electric motor, according
to inherent vehicle parameters, traffic conditions and driving style so as to optimise
the vehicle's fuel consumption.
In particular, this mode activates "zero emissions" electric runningwhen theconditions allow.
In auto mode, the electric motor:

- can drive the vehicle on its own up to
around 36 mph (60 km/h) in "zero emissions" electric running,
depending on the state of charge of the
battery, if the conditions specific to the
vehicle are met and if acceleration is
moderate, -supplements the Diesel engine when
moving off and changing gear, duringacceleration and when traction from the front wheels is inadequate (it automatically adds4 wheel drive),

- is no longer active above 70 mph(120 km / h).



*
ZEV: Z
ero Emissions Vehicle.
This standardmode to use in preference
is activated automaticallyon starting the hybrid system.

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).

Reducing consumption - Fuel
QuestionAnswer
How can I optimise m
y fuel consumption? Give preference to Auto mode as it selects in the best way the "driving energy source" to use in
order to reduce fuel consumption.
You should also adapt
your driving style to the characteristics of hybrid vehicles to get the best
out of it, for example by taking your foot off the accelerator pedal rather than braking and by
anticipating decelerations (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Wh
y do I not manage to reduce my fuel consumption even though I often drive in ZEV(Zero Emissions Vehicle) mode?It is not ZEV mode but Auto mode that is the most appropriate
for reducing fuel consumption, as it selects the best "driving energy source".
ZEV mode (10 0% electric operation) can reduce fuel consumption in some cases. However,
recharging the traction battery has an energy cost.
This is why we recommend using Auto mode more often.
Wh
y does the trip computer sometimes displaythe bars for 28 mpg (10 litres) consumption in
town? The current fuel consumption displa
yed may appear high when the distance covered is very low,
but this generally has very little impact and the true average fuel consumption will remain low.
In town, your hybrid retains very good fuel economy (of the order of 35% better than a non-hybrid
vehicle).
Wh
y is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in Auto mode).
This allows some capacity to be left free for the recovery for energy when going downhill or takingwhen your foot off the accelerator.
Wh
y are there so may fuel aler t messages whenstarting to use the reser ve?To e n c o u r age you to refuel as soon as possible and avoid the loss of hybrid functions.

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.
Control the use of your electrical equipment
