2.16
The “Hybrid Assist” system uses an
electric motor to improve performance
of the combustion engine (acceleration,
starting on a slope etc.). The vehicle
has more acceleration torque available
while consuming less fuel.
BatteriesYour electric vehicle has two types of
battery:
– a 48 V traction battery;
– secondary 12 V battery.
“48 volt” traction battery
Located under the rear floor, this bat-
tery stores the energy recovered during
phases of deceleration. This energy is
used by the hybrid system to provide
additional torque to the combustion
engine.
“HYBRID ASSIST" SYSTEM: introduction (3/5)
Secondary 12V battery
The 12 V battery supplies the energy
required to operate vehicle equipment
(lights, windscreen wipers, ABS etc).
Please see the information under
“12 volt battery” in Section 4.
“48 volt” electrical circuit
The 48 V electrical circuit is denoted
by orange cables and parts bearing the
symbol
ṑ.
All interventions or modi-
fications to the vehicle’s
48 volt electrical system
(components, cables, con-
nectors, traction battery) are strictly
prohibited due to the risks this may
present to your safety. Call an ap-
proved Dealer.
Risk of electric shock.
A
The A symbol denotes the electrical
elements of your vehicle which may
present health risks.
The traction battery does
not require any mainte-
nance. You should not open
it or add any fluid.
Risk of electric shock.

“HYBRID ASSIST" SYSTEM: introduction (4/5)
Indicator of power
consumption/recovery
The indicator 6 allows you to find the
current consumption or recovery of
electrical energy of the 48 volt traction
battery. “Energy recovery” zone A
When driving, if you lift your foot off the
accelerator pedal or apply the brake,
the electric motor generates electrical
current during deceleration, and this
energy is used to slow down the vehicle
and recharge the 48 V traction battery.
“Neutral” zone 0
The 48 volt traction battery does not re-
cover and does not consume any elec-
trical energy.
The display of this information de-
pends on the vehicle.
“Assistance” zone B
The 48 volt traction battery supplies the
electrical energy required for the motor
to reduce fuel consumption.
“Full power” zone
C
While driving, the full power of the
motor is triggered when you go past the
resistance point as you depress the ac-
celerator.
This zone indicates significant con-
sumption of electrical energy. The
wheel 7 is displayed on the instrument
panel to inform you that maximum
power is being supplied to the motor to
increase the engine torque.

Operating faults
– If the  warning light on the in-
strument panel comes on, this indi-
cates that an operating fault has oc-
curred in the system. The operation
of the vehicle is still maintained ;
–
Ú and ® lit up on the in-
strument panel accompanied by the
message “Electric failure DANGER”
indicates a system fault.
For approximately 30 seconds,
the
Ú warning light lights up
on the instrument panel accompa-
nied by the message “Electric failure
DANGER”.
Over the following 30 seconds, the vehicle progressively loses power
from its combustion engine.
Approximately two minutes after the first time the warning appears, the
vehicle speed is limited to 4.34 mph
(7 km/h) approximately.
In all cases, please consult an
Authorised Dealer.
Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow. Switch off the engine and do
not restart it. Contact an approved
Dealer.

“HYBRID ASSIST” SYSTEM: important recommendations
Please read these instructions carefully. Failure to follow these instructions may lead to a risk of fire, serious injury
or electric shocks.
In the event of an accident or impact
Never touch the “48 volt” components or orange cables which are ex\
posed and visible inside or outside the vehicle.
Risk of electric shock.
In the event of serious damage to the 48 V traction battery, leaks may occur:
– never touch any liquids (fluids etc.) coming from the 48 V traction ba\
ttery;
– in the event of contact with the body, wash the affected area with plenty of water and consult a doctor as soon as possibl\
e.
In the event of fire
In the event of fire, make everyone evacuate the vehicle immediately and\
contact the emergency services, informing them that
this is an electric vehicle.
Only use extinguishing agents ABC or BC that are permitted for use with electrical fires. Do not use w\
ater or other extinguish-
ing agents.
In the event of damage to the electrical circuit, please call an authori\
sed dealer.
Washing the vehicle
Never wash the engine compartment, the “48 volt” components and th\
e orange cables with a high pressure washer.
This risks damaging the electric circuit.
Never wash the luggage compartment or the rear bench seat with a water j\
et or high pressure washer.
This risks damaging the electric circuit.
Risk of fire if water leaks into the 48 volt traction battery.

ELECTRONIC PARKING BRAKE (1/3)
Note:
To indicate that the electronic parking
brake is released, a beep sounds and
the message “Apply parking brake” ap-
pears on the instrument panel:
– with the engine running: when the driver’s door is opened;
– for vehicles not fitted with Stop and Start, with the engine switched off
(e.g when the engine stalls): when a
front door is opened.
In this case, pull and release switch 3 to
apply the assisted parking brake.
Assisted release of the parking
brake
The brake will be released as soon as
the vehicle starts and accelerates.
Assisted operation
The electronic parking brake immobi-
lises the vehicle when the engine is
switched off by pressing the engine
start/stop button 1 or turning the ig-
nition key (key in 2 “ ON” 2 posi-
tion).
In all other circumstances, for example
stalling of the engine or placing of
the engine on standby by the Stop
and Start function (refer to the informa-
tion on the “Stop and Start” function in
Section 2), the electronic parking brake
is not applied automatically. Manual
mode must be used. For certain country-specific model ver-
sions, the assisted brake application
function is not activated. Refer to the
information on “Manual operation”.
To confirm that the electronic parking
brake is applied, the message “Parking
brake on” and warning light
}
on the instrument panel and warning
light 4 on the switch 3 light up.
After the engine is switched off, indi-
cator light 4 goes out several minutes
after the assisted parking brake has
been applied and indicator light
}
goes out when the vehicle is locked.
Before leaving the vehicle,
check that the electronic
parking brake is fully ap-
plied. Warning light 4 on
switch 3 and warning light
}
on the instrument panel light up to
show that the parking brake is ap-
plied but go out when the doors are
locked.

ELECTRONIC PARKING BRAKE (2/3)
For vehicles fitted with the Stop and
Start function, with the engine on
standby, the electronic parking brake is
automatically activated if the driver un-
fastens their seat belt or opens the driv-
er's door or gets out of their seat.Brief stop
To apply the electronic parking brake
manually (when stopping at a red light,
or stopping when the engine is running,
etc.): pull and release the switch 3. The
brake is released as soon as the vehi-
cle is started up again.
Special cases
To park on a slope or while towing a
trailer, for example, pull switch 3 for
a few seconds to gain the maximum
braking.
To park the vehicle without applying the
electronic parking brake (if there is a
risk of freezing, for example):
– with the engine running, while si- multaneously depressing the brake
pedal and the switch 3, stop the
engine (do not put it on standby for
vehicles fitted with Stop and Start);
– in gear, release the brake pedal and switch 3.
Manual operationYou can control the electronic parking
brake manually.
Applying the electronic parking
brake
Pull switch 3. Warning light 4 and warn-
ing light
} on the instrument panel
light up.
Releasing the electronic parking
brake
With the ignition on, depress the brake
pedal then press switch 3: indicator
lights 4 and
} go out.
Special feature related to
the Stop and Start function:
if the driver's seat is unfas-
tened before the engine
goes into standby due to the Stop
and Start function, make sure that
the parking brake is applied: the
} indicator light on the instru-
ment panel confirms this. Risk of
loss of immobilisation.
