Presentation of the Hybrid4 system
Thank you for choosing a DS5 Hybrid4; this
vehicle has characteristics that are different from conventional vehicles.
Study this handbook to learn about the specific hybrid functions and for more information, refer
to the "Hybrid system" section.

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.

Hybrid system
Hybrid4 mode selector
The selector allows the user to choose between 4 drive modes for the vehicle.
Turn the dial to the ri
ght or left; the mode selected is confirmed by illumination of the corresponding indicator.
ZEVmode, to force electric runnin
g.Spor
tmode, to make use of the maximum
performance of the vehicle.
4WDmode, to force the vehicle into 4x4 mode.
AUTOmode, for normal use and optimised fuelconsumption.
On star ting the vehicle: with the gear selector in position N, press the brake pedal and press
the STA R T/STOP button to activate the hybrid system.
This lamp comes on when the vehicle is ready
to move off ("Auto" mode is on by default) andso the driver can press the accelerator.
This lamp comes on more or less instantly but may take a few seconds in some cases (inparticular, the time needed for pre-heating the
Diesel engine in cold weather or, for example,
in energy economy mode, ...).
Ready lamp
With the vehicle stationary, press the STA R T/STOP button and check that the Readylamp is off when leaving thevehicle, other wise the hybrid system will still be active.
For more information, refer to the section on "Underbonnet precautions / warnings".

ZEV mode *
(all electric)
Zero emissions vehicle operation is assured10 0 % by electric drive.
This mode forces silent running
at moderate speeds.
It
can be activated when therequired conditions are met, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).
Auto mode
It automatically manages the operation of theDiesel 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 particular, 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,
depending on the state of charge of the
battery, if the conditions specific to the
vehicle are met and if acceleration is
moderate, -supplements the Diesel engine when
moving off and changing gear, duringacceleration and when traction from the front wheels is inadequate (it automatically adds4 wheel drive),
- is no longer active above 70 mph(120 km / h).

This standardmode to use in preference
is activated automaticallyon starting the hybrid system.

Hybrid system
Sport mode
(Diesel and
electric)
4WD mode **
(Diesel and
electric)
This mode allows more dynamic driving byproviding additional performance.Vehicle acceleration and pick-up are
maximised by using the capacity of the electric
motor, supplementing the power of the Diesel
engine.
This mode manages the progressiveness of theaccelerator, the electronic gearbox and the use of the electric motor.
In Sport mode:
- The electric motor can be used up to 70 mph (120 km/h).
This mode provides additional traction
***
at
low speed by driving all 4 wheels of the vehicle continuously: the Diesel engine (front wheel
drive) and the electric motor (rear wheel drive)operate simultaneously and permanently.
Their coupling is managed electronically tooptimise traction on slippery surfaces.
In 4WD mode:
- Power for the electric motor is provided,
if needed, by the alternator-star ter motor
of the front engine. The Diesel engine
operates continuously.
- The additional traction from the electricmotor is available up to 75 mph (120 km/h).
In ZEV m
ode:
- 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.I
f the conditions do not allow this mode, a message that the "electricmode is not currently available"appears in the screen. The ZEV
warning lamp flashes for a few seconds then goes off and the selector comes on in AUTO.
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 recommendedthat you accelerate strongly to ensure that you move off and avoid any risk of getting stuck.The addition of 4WD traction is available whatever:- the state of charge of the tractionbattery, - the altitude.
For more information on "Automatic restarting of the Diesel engine or ZEV mode not available", refer to the corresponding section.
**
4WD: 4 Wheel Drive.
***
This mode will be even more effective if suitable tyres are fitted (winter tyres in
particular).

41Hybrid 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 the
accelerator, … 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
th
an with a conventional vehicle.
100% electric
In all electric running (AUTO or ZEV modes), only the electric motor, 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
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 already star ted since the vehicle was last star ted).
- If the high voltage battery is not sufficiently charged. A minimum of 4 barsin ZEV mode so as to ensure operationover a cer tain distance (in AUTO, electricoperation is accessible for a shor ter period with a lower level of charge).
- When the fuel level enters the reservezone (where rate of consumption of this reser ve is high, ZEV inhibition may continue for some time after refuelling).
- During regeneration of the particleemissions filter, which occursautomatically for 5 to 10 minutes,approximately every 300 miles (500 kms)(or less in extended urban running).
The internal combustion engine may restar t or
ZEV mode may not be available in the variousconditions presented below. The internal combustion engine can beswitched off automatically as soon as these
conditions are lifted. When the conditions described below causethe vehicle to come out of ZEV mode andthe Diesel engine to restar t, the vehicle automatically changes to AUTO mode.
Your vehicle is fitted with the most effective emissions control systems, in par ticular the Particle Emissions Filter (PEF).
At regular inter vals 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
".
Action by the driver
- Moving the gear selector to position M
. - Action on steering mounted control paddles to change gear.- Sustained and sharp acceleration. - Use of demisting.- Use of air conditioning.
Diffi cult weather conditions and
circumstances
- If cer tain conditions or engine temperature requirements make it necessary (such as an engine temperature that is too low for the ambient conditions).
- When the battery is close to maximumcharge (for example: when going down a long hill), because engine recoverybeing no longer possible, the internalcombustion engine restar ts automatically just to provide engine braking.
- If the vehicle encounters a steep slope(car park ramp, ...).
- If the vehicle has been parked in the sunfor a prolonged period.
- When driving in mountainous conditions(altitude).

43Hybrid system
Hybrid4 frequently asked questions
ZEV (Zero Emissions Vehicle) mode
QuestionAnswer
Why 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.
Certain conditions will occasionally prevent the change to ZEV mode, even if the battery hassufficient 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).
Wh
y do I sometimes see an aler t message "Electric mode not available: PEF regeneration
in progress"? This is an messa
ge relating to the regeneration of the par ticle emissions filter (PEF). This is acompletely 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 urban use)
as temporarily the HDi engine will not stop and this message will be displayed at intervals while
regeneration is in progress.
Wh
y is it not possible for me to put the vehicle
into ZEV mode, even though I had just beenrunning electrically in Auto mode? The mana
gement of 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
Vehic le) 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.
Why is it that the system makes me come out o
f
ZEV (Zero Emissions Vehicle) mode; it does notreturn to ZEV automatically when the conditions allow? It is not intended to give pre
ference to ZEV running at any cost, as it is not always the most economical 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 characteristics 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 consumption even though I often drive in ZEV(Zero Emissions Vehicle) mode?It is not ZEV mode but Auto mode that is the most appropriate
for reducing fuel consumption, 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 displaythe bars for 28 mpg (10 litres) consumption in
town? The current fuel consumption displa
yed may appear high when the distance covered is very low,
but this generally has very little impact and the true average fuel consumption will remain 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 partly 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 takingwhen 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.
