Hybrid system
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 the Stop & Start
system - 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 battery - 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 compar tment in the boot, access to which is restricted to trained service
technicians.

The batter
y state of chargeis indicated by 8 horizontal or vertical bars (depending on the screen).

The conventional battery, located under the bonnet, powers the vehicle's 12 V systems. It is yrecharged automatically by the high voltage network.

24
Hybrid system
The electronic power super visor - 4automatically manages the operation of the two power units(Diesel and electric) to provide the lowest consumption.
An inver ter and a transformer are needed to manage the electric power.
The inver ter 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.
The trans
former conver ts the 200 V of the battery pack to 12 V, to power the vehicle's ancillary
systems.
Th
e Stop & Star t system - 5
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.
The stopping and restar ting of the Diesel engine is done in a way that is instantaneous and
transparent for the driver.
Th
e electronicgearbox - 6provides, 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.

Starting - stopping the engine


Before starting Starting at temperatures
above zero
Startin
g at temperatures
below zero
- Press the brake pedal.
- Make a single shor t press (about one second) on the STA R T/STOP
button or
turn the key fully towards the dashboard to
position 3(Starting).
- The steering column unlocks (noise and
noticeable movement).
- Keep your foot on the brake pedal until theHYbrid4 system starts up (the instrument
panel and the Readylamp come on, confirmed by an audible signal).
The hybrid system determines whether it is
necessary to star t the Diesel engine.



- Place the gear selector in position N.

- If the vehicle has Keyless Entry and Starting, simply having the key inside the
vehicle is sufficient.

- Other wise, it is necessary to place the key
in the i
gnition switch.


When the temperature is below zero, you must
initiate pre-heating of the Diesel engine:-Without putting your foot on the brakepedal , make an initial shor t press (about
one second) on the STA R T/STOP button or
turn the key fully towards the dashboard to position 3 (Starting).

- The steering column unlocks (noise and noticeable movement).

- Wait until the pre-heater warning lampgoes off.-With your foot on the brake pedal
, make
a second shor t press on the STA R T/STOP button or leave the key in position 3(Starting).

- Keep your foot on the brake pedal until the HYbrid4 system starts up (the Ready
lampcomes on, confirmed by an audible signal)and the Diesel engine starts.

Hybrid system
- Before switching off the HYbrid4 system, place the gear selector in position N.
- Make a shor t press on the START/STOPbutton or turn the key fully off to position 1(Stop) then remove the key from theignition switch.
- The system shuts down and the steeringcolumn locks.

When your vehicle vehicle moves off in electric mode, it makes no noise. Be very careful of pedestrians as they will not hear you coming.
Switching off
When stationary, ensure that the ignition is switched off and check that the Readylamp yis off when you want to leave the vehicle, otherwise the hybrid system will still be active.


For more information, refer to the
"Underbonnet precautions / warnings"section.

Anti-theft protection
Electronic engine immobiliser
The keys contain an electronic chip which hasa secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
en
gine management system a few minutes after the ignition is switched off and prevents
starting of the engine by anyone who does not have the key.
In the event of a malfunction, you are informed by a message in the instrument panel screen.In this case, your vehicle does not start; contacta PEUGEOT dealer as soon as possible.
Turn the key towards the dashboard to the
intermediate position or with the Keyless Entry
and
Starting key inside the vehicle, press the
"START/STOP" button, with no action on the pedal. This switches on the ignition and so
activates the ancillary equipment.
)Press the "STA R T/STOP" button,
the instrument panel comes on
but the en
gine does not star t. )Press the button again to switch
off the ignition and so allow the
vehicle to be locked.



If you use the accessories positionfor too long, the system automaticallychanges to economy mode to avoid discharging the battery.

Emergency starting with the
electronic key
When the electronic key is in the defined zone and your vehicle does not star t after pressingthe "STA R T/STOP" button: )Open the housing below the "START/STOP" button. )Inser t the electronic key in the location A.)Press the "STA R T/STOP" button.

Emergency switch- off using theelectronic key

In the event of an emergency only, the enginecan be switched of without conditions. To dothis, press and hold the "START/STOP" button
for about 3 seconds.
In this case the steering column locks as soon
as the vehicle stops.
if the electronic key is no longer in the defined zone when you request switching off the engine,
a message appears in the instrument panel.
) Press and hold the "STA R T/STOP"
button for about 3 seconds if you want toforce switching off the engine (note that
restarting will not be possible without
the key).

Hybrid system

Auto mode
It automatically manages the operation of the
Diesel engine and the electric motor, according
to inherent vehicle parameters, traffic
conditions and driving style so as to optimise
the vehicle's fuel consumption.In par ticular, this mode activates "zero emissions" electric runningwhen theconditions allow.
In auto mode, the electric motor
:
- can drive the vehicle on its own up
to around 36 mph
(60 km/h) in "zero
emissions" electric running, dependingon the state of charge of the battery, if the conditions specific to the vehicle are metand if acceleration is moderate, -supplements the Diesel enginewhen moving off and changing gear, during acceleration and when traction from thefront wheels is inadequate (it automaticallyadds4 wheel drive ),
- is no longer active above 70 mph (120 km / h).
ZEV mode *
(all electric)

Zero emissions vehicle operation is assured
10 0 % by electric drive.
This mode forces silent runningat moderatespeeds.
If the conditions do not allow this mode
,a message that the "electric mode is notcurrently available" appears in the screen.
The ZEV warning lamp flashes for a fewseconds then goes off and the selector comes
on in AUTO.
In ZEV mode:


- The accelerator control is progressive.

- Range and acceleration capacity are limited. The maximum speed possible is around 36 mph (60 km/h).

- Under high load or a priority requirement causing the star t of the Diesel engine, thesystem changes automatically to AUTO mode.


This standard
mode to use inpreferenceis activated automaticallyon star ting the hybrid system.


For more information on "Automaticrestarting of the Diesel engine or ZEV mode not available", refer to the corresponding section.


* ZEV: Z
ero Emissions Vehicle.
It can be activated when the
required conditions are met,
particularly if the state of charge of high voltage battery issufficient (from 4 bars).
