"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.
th
is mode activates "zero emissions"
electric running when the conditions allow.
In "A

" mode, the electric motor :
-

on the state of charge of the battery, if the
conditions specific to the vehicle are met
and if acceleration is moderate,

moving off and changing gear, during

I

"ZEV" mode
(all electric)
"Zero emissions vehicle" operation is assured
100 % by electric drive.
th
is mode forces silent running at moderate
speeds. If the conditions do not allow this mode,
the message "electric mode is not currently
available" appears in the screen.

"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.

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.

Starting using another battery
F Remove the plastic cover from the (+) terminal, if your vehicle has one.
F
C
onnect the red cable to the positive
terminal (+) of the flat battery A , then to the
positive terminal (+) of the slave battery B.
F
C
onnect one end of the green or black
cable to the negative terminal (-) of the slave
battery B (or earth point on the other vehicle).
F
C
onnect the other end of the green or black
cable to the earth point C on the broken
down vehicle (or on the engine mounting).
F
S
tart the engine of the vehicle with the
good battery and leave it running for a few
minutes. First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) terminal when
the engine is running.
When your vehicle's battery is discharged, the
engine can be started using a slave battery
(external or on another vehicle) and jump lead
cables.
F O perate the starter on the broken down
vehicle and let the engine run.
I
f the engine does not start straight away,
switch off the ignition and wait a few
moments before trying again.
F
W
ait until the engine returns to idle then
disconnect the jump lead cables in the
reverse order.
F
R
efit the plastic cover to the (+) terminal, if
your vehicle has one. Do not disconnect the cables too
quickly; leave them connected for a few
minutes (until the engine returns to idle)
otherwise there is a risk that the battery
would be under-charged, with the need
then to repeat the operation.
Starting the vehicle when the battery
is flat must be done with the electronic
key inside the vehicle, the driver's
door closed and the driver's seat belt
fastened.
Some functions are not available if the
battery is not sufficiently charged.
