"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.

"SPORT" mode
(Diesel and
electric)
this mode allows more dynamic driving by
providing additional performance.
Vehicle acceleration and pick-up are
maximised by using the capacity of the electric
motor, supplementing the power of the Diesel
engine.
th

is mode manages the response of the
accelerator, the electronic gearbox and the use
of the electric motor.
In "SPOR
t" m

ode:
-
t
h
e electric motor can be used up to
75 mph (120 km/h).
"4WD" mode*
(Diesel and
electric)
this mode provides additional traction ** at
low speed by driving all 4 wheels of the vehicle
continuously: the Diesel engine (front wheel
drive) and the electric motor (rear wheel drive)
operate simultaneously and permanently.
th

eir coupling is managed electronically to
optimise traction when grip is poor.
In 4WD mode:
-

P
ower for the electric motor is provided, if
necessary, by the alternator-starter motor
of the front engine.
t
h
e Diesel engine
operates continuously.
-
t
h
e additional traction from the electric
motor is available up to 75 mph (120 km/h).th is mode should be used on snow
covered roads or difficult ground
(mud, sand, ...).
In this mode, in severe conditions
and if the circumstances allow, it is
recommended that you accelerate
strongly to facilitate moving off and
reduce the risk of getting stuck.
th

e addition of "4WD" traction is
available whatever:
-

t
he state of charge of the traction
battery,
-

t
he altitude.
Be aware of the ground clearance of
your vehicle: around 184 mm (with the
vehicle in working order: driver only and
the fuel tank full) in ideal conditions.
th

is value will vary with vehicle load,
the nature of the ground sur face and
the surroundings.
If the driver considers that the vehicle
can traverse an obstacle, they assume
entire responsibility for this.
* "4WD": 4 Wheel Drive.
**
t
h
is mode will be even more effective if tyres
more suitable for the conditions are fitted
("winter" tyres in particular). When driving on flooded roads or when
crossing a ford, drive at walking pace.

energy consumption / generation indicator
the indicator dial provides real time information
on the total power used, combining electric and
Diesel.
It comprises three main zones.
CHARGE zone
Zone which indicates that the vehicle is
in electrical energy recovery phase: on
deceleration, braking (partially or particularly
with your foot off the accelerator, to use
in preference as this gives better energy
rec over y).
th

is allows the high voltage battery to be
recharged using "free" energy which can then
be reused for future energy requirements.
POWER zone
Zone which indicates an increased cumulative
power demand from your hybrid vehicle,
taking account of the combined power available
from the Diesel engine and the electric motor.
Zone which indicates that the vehicle is
optimising its energy consumption , electric,
Diesel or a combination of both.
th

is 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).ECO zone

Examples of displays
On starting and when stationary
there is no flow of energy (the Stop & Start system stops and
restarts 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 energy 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 (Au tO o r ZeV m odes), only the electric
motor, powered by the battery, drives the rear wheels.
th

e display of "Zero e
m

is off and the vehicle is producing no CO

HYbrid4 frequently asked questions
ZEV (Zero Emissions Vehicle) mode
QuestionAnswer
Why is it not always possible for me to put the vehicle
into Z
eV (

Zero
e
m

issions Vehicle) mode even though
the battery is well charged?
th

is situation is temporary.
Certain conditions will occasionally prevent the change to Z
eV m

ode, 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 particle filter (FAP).
Why do I sometimes see an alert message "
el

ectric
mode not available: FAP regeneration in progress"?
th

is is an message relating to the regeneration of the particle filter (FAP). t
h
is 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.
th

is process is not generally noticed by the driver.
On the other hand, in the case of a hybrid, this phenomenon may be noticeable (in urban
use) as temporarily the HDi engine will not stop and this message will be displayed at
intervals while regeneration is in progress.
Why is it not possible for me to put the vehicle into
Z
eV m

ode, even though I had just been running
electrically in Auto mode?
th

e management of Z
eV i
s different from Auto mode.
Changing to Z
eV m

ode 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.
Why is the range in Z
eV (

Zero e
m
issions Vehicle)
mode lower when climbing?
th

e 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.
Why is it that the system makes me come out of Z
eV
(

Zero
e
m

issions Vehicle) mode; it does not return to
Z
eV a

utomatically when the conditions allow? It is not intended to give preference to Z
eV r

unning at any cost, as it is not always the most
economical mode.
So the system returns automatically to Auto mode.

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.

Air conditioning
QuestionAnswer
It seems to me that the vehicle runs less on electric
when the heating or air conditioning is operating, is
that right?
the
demand for heating or air conditioning may require the starting of the Diesel engine
until the desired level of comfort is attained.
Normal hybrid operation is simply put back.
t
h
e period can be longer under low or very high
ambient temperatures.
It seems to me that when it is very hot and the air
conditioning is working, the vehicle runs on electric for
shorter periods. Is that right? When it is hot, the periods when the Diesel engine is put on standby and the vehicle runs on
electric are necessarily restricted in order to limit the difference between the temperature in
the vehicle and the level of comfort selected.
In very hot weather, it is always possible to press the
e
c
o OFF button (which brings the
vehicle out of Z
eV m

ode and prevents electric running or the stopping of the engine) to give
preference to temperature control (keeps the air conditioning running).
Special HYbrid4 features
Question Answer
Can I tow with my hybrid vehicle and how much? A HYbrid4 vehicle can tow between 500 kg and 800 kg (see the "
to
wing" section).
th

is allows a jet ski or two-wheeler on a trailer to be towed, for example.
th

e "technical" reason for the limit is related to maintaining adequate cooling capacity for
the internal combustion engine as well as the hybrid components that are also cooled by the
engine's cooling system.
Why does engine braking seem so strong? When you take your foot off the accelerator, the engine braking results mainly from the
energy recovery by the electric motor.
th

is leads to a higher level of deceleration than a conventional vehicle and so allows the
recovery of free energy.
