For economical driving, caring for the environment
the fuel consumption of a vehicle varies greatly :
- a ccording to the driver's style of driving (moderate, aggressive, fast, ...),
-
a

ccording 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 Auto mode of the selector whenever possible (the mode is activated
automatically when starting) including for urban journeys.
th

is mode optimises the use of the energy sources (internal combustion engine and/or electric) contrary to other
modes, which are for use in particular cases.
Gear lever
use the automatic mode A as much as possible as this optimises gear changes to suit the requirements.
Drive smoothly
Stay in the "eco" zone displayed in the energy consumption / generation indicator: accelerate gently, drive at
steady speeds 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.
t
h
e 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.
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, …).
Observe the recommendations on checks (regular check of tyre pressures, correct tyre pressures, …) and routine
servicing.

the electronic power super visor - 4 automatically manages the operation of the two power units
(Diesel and electric) to provide the lowest consumption.
An inverter and a transformer are needed to manage the electric power.
th
e inverter acts on the torque of the electric motor, by regulating the current coming from the high
voltage battery pack. Its operating range is between 150 and 270 volts.
th

e transformer converts the 200 V of the battery pack to 12 V, to power the vehicle's ancillary
systems.
th

e alternator-starter motor - 5 assures the Stop & Star t function which allows the Diesel
engine 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.
th

e stopping and restarting of the Diesel engine is done in a way that is instantaneous and
transparent for the driver.
It also provides additional charging of the batteries (4x4 mode for example or under-charged high
voltage battery).
th

e electronic gearbox - 6 provides, in automatic mode, significant savings in fuel consumption
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.

Ready lamp
With the gear selector in position N, press the
brake pedal and start the hybrid system.
th

is lamp comes on when the vehicle is ready
to move off ("Auto" mode is on by default) and
so the driver can press the accelerator.
th

is lamp comes on more or less instantly
but may take a few seconds in some cases
(in particular, the time needed for pre-heating
the Diesel engine in cold weather or in energy
economy mode, for example, ...).

"AUTO" mode
It automatically manages the operation of the
Diesel engine and the electric motor, according
to vehicle parameters, traffic conditions and
driving style so as to optimise the vehicle's
fuel consumption.

Automatic restarting of the Diesel engine or ZEV mode NOT available
the internal combustion engine may restart
or ZeV mode may not be available in the
various conditions presented below.
th

e internal combustion engine can be
switched off automatically as soon as these
conditions are lifted.

the vehicle to come out of Z

Your vehicle is fitted with the most effective
emissions control systems, in particular the

produce energy for the self-cleaning of this filter.
During this FAP regeneration phase, electric
running is purposely made unavailable and
is accompanied by a message " Electric
mode not available: FA P regeneration in
progress ".

Reducing consumption - Fuel
QuestionAnswer
How can I optimise my fuel consumption?
gi
ve 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, ...).
Why do I not manage to reduce my fuel consumption
even though I often drive in Z
eV (

Zero e
m
issions
Vehicle) mode? It is not Z
eV m

ode but Auto mode that is the most appropriate for reducing fuel
consumption, as it selects the best "driving energy source".
Z
eV m

ode (100% electric operation) can reduce fuel consumption in some cases. However,
recharging the traction battery has an energy cost.
th

is is why we recommend using Auto mode more often.
Why does the trip computer sometimes display the
bars for 28 mpg (10 litres) consumption in town?
th

e current fuel consumption displayed 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).
Why is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in Auto mode).
th

is allows some capacity to be left free for the recovery for energy when going downhill or
taking when your foot off the accelerator.
Why are there so may fuel alert messages when
starting to use the reserve?
to e

ncourage 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 this
optimises gear changes to suit the
circumstances, and the AUTO mode of the
HYbrid4 mode selector.
When moving off, accelerate normally
up to the desired speed ( POWER zone
between 20 and 40 %).
At steady speeds, drive gently with small
movements of the accelerator pedal ( ECO or
CHARGE zone), run in electric mode as often
as possible when driving at low speed.
Anticipate the need to slow down and use
engine braking ( CHARGE zone), so as to
make use of free energy recovery while
keeping light pressure on the accelerator
pedal.
Control the use of your
electrical equipment
Before moving off, if the passenger
compartment is too warm, ventilate it by
opening 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 can
help 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 foglamps
when the level of light does not require
their


use. Avoid running the Diesel engine when
stationary, particularly in winter; your vehicle
will warm up much faster while driving.
As a passenger, if you avoid connecting
your multimedia devices (film, music, video
game...), you will contribute towards limiting
the consumption of electrical energy, and so
of fuel.
Disconnect your portable devices before
leaving the vehicle.
