Main parts of the HYbrid4 system
the HDi Diesel engine - 1, located at the front, drives the front wheels and provides most of the
power needed to drive the vehicle.
It is fitted with an alternator-starter motor (Stop & Star t ) - 5 which recharges the batteries and
provides additional power when needed (in 4x4 mode).
th

e electric motor - 2 , located at the rear, drives the rear wheels on its own, or supplements the
Diesel engine, according to the hybrid mode selected.
It recovers energy and charges the batteries during phases of deceleration of the vehicle and is
active up to 70 mph (120 km/h).
A 200 V NI-MH high voltage batter y - 3 , provides a source of energy for the rear electric motor.
Its charging rate is managed automatically by the vehicle during phases of deceleration.
It is located in a compartment in the boot, access to which is restricted to trained service
technicians.
th

e battery state of charge is indicated by 8 horizontal or vertical bars (depending on the screen).
th

e conventional battery , located under the bonnet, powers the vehicle's 12 V systems. It is
recharged automatically by the high voltage network.
.
Hybrid system

14
508RXH_en_Chap00c_systeme-hybride_ed01-2014
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.

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.

High voltage
Before doing any work on
the vehicle, switch off the
ignition (Ready lamp off).
High voltage cables
High voltage cables are routed under the
vehicle (sills); take care not to damage them
when the vehicle is used for off-road activity
(such as covering rough ground).
Battery precautions
the high voltage battery must not in any
circumstances be charged from an external
source and must only be handled by a
workshop technician.
th

ere is the risk of serious burns, as well as
electric arcs that could cause serious injury or
even death.
A used Ni-MH (Nickel Metal Hydride) type
high voltage battery must be removed in an
appropriate manner by a repair workshop,
so that its recycling presents no risk to the
environment.
ta

ke care to position lifting equipment
( jack, hoist, ...) at the locations provided
to avoid damaging the cables.
th

e voltage used for the operation of the
electric motor is in the range 150 to 270 Volts.
Be sure to take account of the warning labels
fitted to the vehicle.
ta

ke great care regarding the high voltage and
high temperatures of components carrying the
current.
Emergency cut-off
In the event of an accident, a cut-off system
blocks the high voltage current and cuts off
the fuel pump; your vehicle can no longer be
started.
to r

estart the hybrid system, contact a
P
e

uge
Ot d
ealer.
Never touch, dismantle, remove or
replace the high voltage parts, orange
cables or connectors, even in the event
of an accident.

underbonnet precautions / warnings
Always ensure that the
ignition is switched off
(Ready lamp off) before
opening the bonnet.
Before doing anything under the
bonnet, to avoid the risk of serious
injury switch off the ignition and verify
that the Ready lamp in the dashboard
is of f.
Also ensure that the ignition is switched
off when refuelling to avoid the engine
restarting.
th

e alternator-starter motor of your hybrid
vehicle is also supplied at high voltage. If the
vehicle ignition has not been switched off, there
is a risk of the engine restarting at any time.
