Driving safely


Before starting 31


Starting when the temperature isabove zero




- The instrument panel and the Ready
lampcome on, confirmed by an audible signal.

- The dial in the centre console is in AUTO
mode.



- Place the
gear selector in position N.

- Inser t the electronic key in the reader or
keep the electronic key inside the vehicle.


-
Press the brake pedal.

- Make single short press (about 1 second)on the START/STOPbutton.



Moving off




- While maintaining pressure on the brakepedal, move the gear selector to position Ato go forwards or Rfor reverse.

- Ta k e
your foot off the brake pedal, you can
then move off.


With temperatures below zero, you have to initiate pre-heating of the Diesel engine: - Withoutpressing the brake pedal,make an initial shor t press on theSTA R T/STOP button. - Wait until the pre-heater warninglamp goes off.
-With
you foot on the brake pedal, make a second shor t press on theSTA R T/STOP button.

If this warning lamp comes on in
the instrument panel, automatic application / release is
deactivated. The parking brake must
be applied and released manually. y


Before leaving the vehicle, check
that the the brake warning lamp and
the Pwarning lamp in the controllever A are on fixed (not flashing).

If towing a trailer or caravan or if theslope might vary (transpor t by boat or lorry, recovery of the vehicle...) make a maximum application of the parking brake - by making a long pull on the control lever A
- to immobilise thevehicle.

Electric parking brake
Manual Application/Release
Manual applicationof the parking brake is possible by pulling
the control lever A.With the ignition on, manual release
of the parking brake is possible by pressing the brake pedal
and pulling
then releasing
the control lever A
.


If an audible signal is heard on opening the driver's door with the hybrid system active, apply the parking brake
manually. Do not leave a child alone in the vehiclewith the ignition on; they might releasethe parking brake.


Automatic Application / Release

Press the accelerator pedal, the parking brake
is released automatically and progressively as you move off.
With the vehicle stationary, the parking brake
is applied automatically on switching off the
ignition (Readylamp off).

Presentation
The Hybrid4 technology allows two sources of energy to be associated in an effective manner:
the Diesel HDi engine, which drives the front
wheels and the electric motor, which drives the
rear wheels.
These two motors can operate alternately or simultaneously, according to the hybrid modeselected and the driving conditions.
The electric motor alone provides power for
the vehicle in "ZEV" (Zero Emissions Vehicle) mode, and in "Auto" mode for running at slowspeed and low load. It also assists the Dieselengine when moving off, accelerating and changing gear.
The battery that powers the electric motor is recharged during phases of deceleration andstores the energy for subsequent use.

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 i
s fitted with the Stop & Start
system - 5which 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 hi
gh 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 servicetechnicians.
The batter
y state of charge
is indicated by 8 horizontal or vertical bars (depending on the screen).

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

The electronic power super visor - 4automatically manages the operation of the twopower units (Diesel and electric) to provide the
lowest consumption.
An inverter 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 operatingrange is between 150 and 270 volts.
The transformer converts the 200 V of thebattery pack to 12 V, to power the vehicle'sancillary systems.
The Stop & Start system - 5allows the Dieselengine 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.
The electronic gearbox- 6
provides, in
automatic mode, significant savings in fuelconsumption 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.
