Sport mode
(Diesel and
electric)

This mode allows more dynamic driving byproviding additional performance. Vehicle acceleration and pick-up aremaximised by using the capacity of the electricmotor, supplementing the power of the Dieselengine.
This mode manages the progressiveness of the
accelerator, the electronic gearbox and the useof the electric motor.
In Spor t mode:


-
The electric motor can be used up to
70 mph (120 km/h).
4WD mode **
(Diesel and
electric)
This mode provides additional traction*** at low speed by driving all 4 wheels of the vehiclecontinuously: the Diesel engine (front wheel
drive) and the electric motor (rear wheel drive)
operate simultaneously and permanently.
Their couplin
g is managed electronically to
optimise traction on slippery surfaces.
In 4WD mode:
- Power for the electric motor is provided,
if needed, b
y the alternator-star ter motor
of the front engine. The Diesel engine
operates continuously.
- The additional traction from the electric
motor is available up to 75 mph (120 km/h).

This mode should be used on snow covered roads or difficult ground (mud,sand, ...).
In this mode, in severe conditions and if the circumstances allow, it is recommended that you accelerate strongly to ensure that you move off and avoid any risk of getting stuck.
The addition of 4WD traction isavailable whatever:


- the state of charge of the traction battery,

- the altitude.
Be aware of the ground clearance of your vehicle: around 184 mm (with the vehicle in working order: driver only and the fuel tank full) in ideal conditions.
This value will vary with vehicle load,the nature of the ground surface and the surroundings.
If the driver considers that the vehicle
can traverse an obstacle, they assumeentire responsibility for this.
**
4WD: 4 Wheel Drive.
***
This mode will be even more effective if suitable tyres are fitted (winter tyres in
particular
).

Energy consumption / generation indicator
The indicator dial provides real time information
on the total power used, combining electric and
Di
esel.
It comprises three main zones.

CHARGE zone

Zone which indicates that the vehicle isin electrical energy recovery
phase: on
deceleration, braking (partially or par ticularlywith your foot off the accelerator (to use
in preference as this gives better energy recovery).
This allows the high voltage battery to be recharged using "free" energy
which can thenbe reusedfor future energy requirements.


POWER zone

Zone which indicates an increased cumulative power demand
from your hybrid vehicle,
taking account of the combined capacities of
the Diesel engine and the electric motor.
Zone which indicates that the vehicle is
optimising its energy consumption, electric,
Diesel or a combination of both.
This zone corresponds to phases of electric
running as well as to phases of optimum use of
the Diesel engine, which are easily accessible
with a suitable driving style (smooth "eco-citizen" driving).
ECO zone

Hybrid system
Examples of displays
On starting and when stationary
There is no flow of energy (the Stop & Star t system stops and restar ts the Diesel engine automatically).
Energy recovery
During this phase (deceleration, braking, foot off theaccelerator, … all modes), the battery is recharged by the electric motor/generator, then being driven by the rear wheels.
You can maximise this energy recovery by taking your foot off
the accelerator pedal, deceleration will then be less marked than
with
a conventional vehicle.
100% electric
In all electric running (AUTO or ZEV modes), only the electricmotor, powered by the battery, drives the rear wheels.
The display of "Zero Emission" indicates that the Diesel engine
is off and the vehicle is producing no CO2.

Automatic restarting of the Diesel engine or ZEV mode NOT available

The internal combustion engine may restar t or ZEV mode may not be available in the various conditions presented below.

The internal combustion engine can be switched off automatically as soon as these conditions are lifted. When the conditions described below causethe vehicle to come out of ZEV mode and the Diesel engine to restar t, the vehicleautomatically changes to AUTO mode.
Diffi cult weather conditions and circumstances
- If certain conditions or engine
temperature requirements make it necessary (such as an enginetemperature that is too low for the ambient conditions). - When the battery is close to maximum charge (for example: when goingdown a long hill), because enginerecovery being no longer possible, theinternal combustion engine restarts automatically just to provide engine braking.- If the vehicle encounters a steep slope (car park ramp, ...).- If the vehicle has been parked in the sun for a prolonged period.- When driving in mountainous conditions (altitude).
Your vehicle is fitted with the most effectiveemissions control systems, in par ticular theParticle Emissions Filter (PEF). At regular intervals your Diesel engine will produce energy for the self-cleaning of this filter.During this PEF regeneration phase, electric running is purposely made unavailable andis accompanied by a message "Electricmode not available: PEF regeneration inprogress
".
Maintaining the performance of the system
- When the vehicle exceeds 18 mph
(30 km/h) after moving off (if the internal combustion engine has not alreadystarted since the vehicle was last started). - If the high voltage battery is notsufficiently charged. A minimum of 4 bars in ZEV mode so as to ensure operation over a cer tain distance (in AUTO, electric operation is accessiblefor a shorter period with a lower level of charge).- When the fuel level enters the reserve zone (where rate of consumption of this reserve is high, ZEV inhibition maycontinue for some time after refuelling).- During regeneration of the par ticle emissions filter, which occurs
automatically for 5 to 10 minutes, approximately every 300 miles(500 kms) (or less in extended urban running).


Action by the driver



- Moving the gear selector to position M.

- Action on steering mounted controlpaddles to change gear.

- Sustained and sharp acceleration.

- Use of demisting.

- Use of air conditioning.

HYbrid4 frequently asked questions
ZEV (Zero Emissions Vehicle) mode
Question Answer
Wh
y is it not always possible for me to put the vehicle
into ZEV (Zero Emissions Vehicle) mode even though
the battery is well charged?
This situation is temporary.
Cer tain conditions will occasionally prevent the change to ZEV mode, even if the battery
has sufficient charge, such as, for example, very cold conditions, altitude, demisting, high
demand for heating or air conditioning, regeneration of the par ticle emissions filter (PEF).
Why do I sometimes see an aler t message "Electric
mode not available: PEF regeneration in progress"?
This is an message relating to the regeneration of the par ticle emissions filter (PEF). This
is a completely normal process that takes place every 240 or 300 miles (400 or 500 km) (or
more frequently in prolonged urban use), as on a conventional HDi vehicle.
This process is not generally noticed by the driver.

On the other hand, in the case of a hybrid, this phenomenon may be noticeable (in urbanuse) as temporarily the HDi engine will not stop and this message will be displayed at
inter vals while regeneration is in progress.
Why is it not possible
for me to put the vehicle into ZEV mode, even though I had just been runningelectrically in Auto mode? The management o
f ZEV is different from Auto mode.
Changing to ZEV mode is only possible with a battery charge of at least 4 bars, in order to
assure sufficient range.
In Auto mode, the system alone manages the conditions for changing temporarily to electric
mode, for shorter periods and with a lower state of charge of the battery.
Wh
y is the range in ZEV (Zero Emissions Vehicle) mode lower when climbing? The vehicle needs more energy when climbing than when running on the level.
So it is better to stay in Auto mode, which will favour operation of the Diesel engine.
Wh
y is it that the system makes me come out of ZEV(Zero Emissions Vehicle) mode; it does not return toZEV automatically when the conditions allow? It is not intended to
give preference to ZEV running at any cost, as it is not always the mosteconomical mode.
So the system returns automatically to Auto mode.

Reducing consumption - Fuel
QuestionAnswer
How can I optimise m
y fuel consumption? Give preference to Auto mode as it selects in the best way the "driving energy source" to
use in order to reduce fuel consumption.
You should also adapt your driving style to the special features of hybrid vehicles to get the
best out of it, for example by taking your foot off the accelerator pedal rather than braking and by anticipating decelerations (entering a built-up area, stop at traffic lights, stop at halt
signs, ...).
Wh
y do I not manage to reduce my fuel consumptioneven though I often drive in ZEV (Zero EmissionsVehicle) mode? It is not ZEV mode but Auto mode that is the most appropriate for reducin
g fuelconsumption, as it selects the best "driving energy source".
ZEV mode (10 0% electric operation) can reduce fuel consumption in some cases. However,recharging the traction battery has an energy cost.
This is why we recommend using Auto mode more often.
Wh
y does the trip computer sometimes display the
bars for 28 mpg (10 litres) consumption in town?The current fuel consumption displayed may appear high when the distance covered is
very low, but this generally has very little impact and the true average fuel consumption willremain low.
In town, your hybrid retains very good fuel economy (of the order of 35% better than a non-hybrid vehicle).
Wh
y is my battery rarely fully charged? A par tly charged battery is normal operation (4 to 5 bars on average in Auto mode).
This allows some capacity to be left free for the recovery for energy when going downhill or
taking when your foot off the accelerator.
Wh
y are there so may fuel aler t messages whenstarting to use the reser ve?To e n c o u r age you to refuel as soon as possible and avoid the loss of hybrid functions.

Air conditioning
QuestionAnswer
It
seems to me that the vehicle runs less on electricwhen the heating or air conditioning is operating, is
that right? The demand for heatin
g or air conditioning may require the star ting of the Diesel engine until
the desired level of comfort is attained.
Normal hybrid operation is simply put back. The period can be higher under low or very high
ambient temperatures.
It seems to me that when it is ver
y hot and the air conditioning is working, the vehicle runs on electric for shor ter periods. Is that right? When it is hot, the periods when the Diesel en
gine 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 Eco OFF button (which brings the
vehicle out of ZEV mode 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 "Towing" section).
This allows a jet ski or two-wheeler on a trailer to be towed, for example.
The "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 theengine's cooling system.
Wh
y 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.
This leads to a higher level of deceleration than a conventional vehicle and so allows the recovery of free energy.
