HYBRID4 MODE SELECTOR
AUTO Mode
"Zero emissions vehicle" operation is
provided by 100% electric drive.
This mode allows silent running to be
imposed at moderate speed (urban,
parking, …).
This mode can be activated when con-
ditions permit (in particular if the state
of charge of the high voltage battery is
high enough) and allows driving up to
around 35 mph (60 km/h).
ZEV mode(Zero Emissions Vehicle)
When stationary and when starting
the hybrid system
This mode automatically manages the
operation of the Diesel engine and the
electric motor, separately or together,
according to the vehicle's own inherent
parameters, the driving conditions and
the driving style.
The standard mode to use
in preference for optimum
fuel consumption.
This mode is activated automatically
on starting the vehicle.
In particular, this mode will activate "zero
emissions" electric operation when the
conditions permit.
The electric motor is also used to supple-
ment the Diesel engine when moving off
and changing gear and when the front
wheels do not provide suffi cient traction.
The range depends on the
state of charge of the battery
and the driving conditions (of
the order of 1.2 miles (2 km)
in favourable conditions).
In this mode, the average battery charge
is 4 to 5 bars, so as to preserve a mar-
gin of energy recovery on deceleration
or going downhill (free energy).

Main parts of the HYbrid4 system
The HDi Diesel engine - 1
, located at the front, drives the front wheels and pro-
vides most of the power needed to drive the vehicle.
It is fi tted with the Stop & Start
system - 5
which recharges the batteries and pro-
vides additional power when needed (in 4x4 mode).
The 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 decel-
eration.
It is located in a compartment in the boot, access to which is restricted to trained
service technicians.
The battery state of charge
is 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 recharged automatically by the high voltage network.

ZEV mode * (all electric)
Zero emissions vehicle operation is as-
sured 100 % by electric drive.
This mode forces silent running
at
moderate speeds.
* ZEV: Zero Emissions Vehicle. In ZEV mode:
- The accelerator control is progres-
sive.
- Range and acceleration capacity
are limited. The maximum speed
possible is around 36 mph (60 km/h).
- Under high load or a priority require-
ment causing the start of the Diesel
engine, the system changes auto-
matically to AUTO mode.
It can be activated when
the required conditions are
met, particularly if the state
of charge of high voltage
battery is suffi cient (from 4 bars).
If the conditions do not allow
this mode, a message that
the "electric mode is not cur-
rently available" appears in
the screen. The ZEV warning
lamp fl ashes for a few seconds then
goes off and the selector comes on in
AUTO.
Auto mode
It automatically manages the operation
of the Diesel engine and the electric
motor, according to inherent vehicle pa-
rameters, traffi c conditions and driving
style so as to optimise the vehicle's
fuel consumption
.
In particular, this mode activates "zero
emissions" electric running
when the
conditions 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, depend-
ing on the state of charge of the bat-
tery, if the conditions specifi c to the
vehicle are met and if acceleration is
moderate,
- supplements the Diesel engine
when moving off and changing gear,
during acceleration and when trac-
tion from the front wheels is inade-
quate (it automatically adds
4 wheel
drive
),
- is no longer active above 70 mph
(120 km/h).
This standard
mode to use in
preference
is activated auto-
matically
on starting the hy-
brid system.

tomatic restarting of the Diesel
engine or ZEV mode not avail-
able", refer to the correspond-

200 V HIGH VOLTAGE BATTERY
The 200 V high voltage battery cannot
be recharged from a mains supply.
The battery is Ni-MH (Nickel Metal Hy-
dride) and is located below the boot
fl oor, close to the electric motor.
Charging
The charging takes place automati-
cally when driving
.
The energy recovery can be faster dur-
ing deceleration.
The average state of charge is 4 to
5 bars, so preserving a margin for en-
ergy recovery when deceleration of go-
ing downhill (free energy).
The battery is charged when the vehi-
cle decelerates, the electric motor then
becomes a generator and converts ki-
netic energy into electrical energy (ex-
cept if the speed of the vehicle is above
70 mph (120 km/h)).
The battery is not recharged from a
mains supply.
The battery may also be charged auto-
matically when required by the Stop &
Start system of the Diesel engine.
To preserve the service life of
the battery, the level of charge
never falls below 20 %, even
if a level of 0 bars is displayed
after ZEV running.
Where the battery is close to maxi-
mum, vehicle deceleration with your
foot off the accelerator pedal will be
at a lower level.
This recovery allows the use of "free"
energy.
The battery charging time is very short
and is continuous.
A discharged battery (following ZEV
running or high load, for example) will
quickly return to a state of charge suf-
fi cient for full operation of the different
hybrid modes.
