2016 Citroen DS5 HYBRID display

27Hybrid4 system











200 V high voltage battery


The Ni-Mh (Nickel-Metal Hydride) technology
used for the high voltage battery is suited to
the frequent partial charging and discharging
cycles related to the operation of a hybrid
vehicle.
The battery is installed close to the electric
motor, below the boot trim, behind the storage
well.


Charging


The battery recharges automatically while
travelling.
The battery is charged when the vehicle
decelerates and when going downhill, the
electric motor then becomes a generator and
conver ts kinetic energy into electrical energy
(except if the speed of the vehicle is above
70 mph (120 km/h)).
This recovery allows the use of "free" energy.
The battery may also be partially charged up
to a level of 4 to 5 bars, using the alternator-
starter motor (Stop & Start) of the HDi Diesel
engine.
The average state of charge is 4 to 5 bars, so
preser ving a margin for energy recovery when
deceleration or going downhill (free energy).

To preser ve the ser vice life of the
battery, the level of charge never
falls below 20%, even if no bars are
displayed on the gauge after ZEV

running.
Where the battery is close to maximum,
vehicle deceleration with your foot off
the accelerator pedal will be at a lower
level.
The battery charging time is very short.
Once it is discharged, following ZEV
running
or high load, the battery will reach its optimum
level of charge after around 10 minutes.

The battery is not recharged from a
mains power supply.

Displays in the instrument panel

Moving off




)
To start the engine, place the
gear selector in position N
.



)
Release the parking brake by pulling the
control lever, if automatic operation has
been deactivated.

)
Progressively release the brake pedal.
Before leaving the vehicle, place the
gear selector in position N
and then
you must stop the Hybrid4 system by
switching off the ignition ( READY
lamp
off).



)
Place your foot on the brake

when a message appears in the
instrument panel screen.

)
Press the brake pedal down fully.

)
Start the Hybrid4 system.


If the Hybrid4 system does not activate:


- If N
is flashing in the instrument
panel, move the gear selector to
position A
then to position N
.

- If the message "Foot on brake" is
displayed, press the brake pedal
firmly.




)
Select a drive mode (position A
or M
) or
reverse (position R
).

For optimum acceleration, for example
when overtaking another vehicle, press
the accelerator pedal firmly past the
point of resistance.


)
After starting the vehicle, select position A

for enter automated mode.



Automated mode



A
appears in the instrument panel
screen.

The gearbox is then operating in auto-active
mode, without any action on the part of the
driver. It continuously selects the most suitable
gear, depending on the:


- style of driving,

- profile of the road.

A
or M1
or R
appears in the
instrument panel screen.
)
If the parking brake is released, the vehicle
moves off.
If the parking brake is applied and
automatic mode is activated, accelerate
progressively.

On sharp acceleration in manual mode,
the gearbox will not change up unless
the driver acts on the gear lever or the
steering mounted paddles.
Never select neutral N
while the vehicle
is moving.


At very low speed, if reverse gear
is requested, this will only be taken
into account when the vehicle is
immobilised. A warning lamp appears
in the instrument panel screen.
Only engage reverse gear R
when the
vehicle is immobilised with the brake
pedal pressed.
This selective gear change mode enables you
to overtake, for example, while still remaining in
automated mode.


)
Operate the +
or -
steering mounted control
paddle.
The gearbox engages the gear requested if the
engine speed permits. A
is still displayed in the
instrument panel.

Manual mode




)
When the vehicle has moved off, select
position M
to change to manual mode.

)
Operate the +
or -
steering mounted control
paddles.

The gear change commands are only carried
out if the engine speed permits. The internal
combustion engine is still running.
It is not necessary to release the accelerator
during gear changes.
When braking or slowing down, the gearbox
changes down automatically to permit
acceleration in the correct gear.


Manual gear changing



A
disappears and the
gears engaged M1...M6

appear successively in the
instrument panel screen. After a few moments without any action on
the controls, the gearbox resumes automatic
control of the gears.

Frequently asked questions


100% electric mode (zero emissions)



Question



Answer


Why is it not always possible for me to select ZEV

(Zero Emissions Vehicle) mode even though the battery
seems well charged? This situation is temporary.
Certain 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 particle filter (FAP).
Why do I sometimes see an alert message " Electric
mode not available: FAP regeneration in progress" ? This is a message which indicates that regeneration of the particle filter (FAP) is in progress.
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 Diesel vehicle.
In the case of a conventional HDi Diesel vehicle, this process is not generally noticed by the
driver.
On the other hand, in the case of Hybrid4 this phenomenon may be noticeable (in urban use)
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 running electrically
in AUTO
mode? The management 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.
Why is the range in ZEV
mode lower when going uphill? The vehicle needs more energy when going uphill than when running on the level.
So it is better to stay in AUTO
mode, which will favour operation of the HDi Diesel engine.
Why is it that the system makes me come out of ZEV

mode; it does not return to ZEV
mode automatically
when the conditions allow? It is not intended to give preference to ZEV
running at any cost, as it is not always the
most economical mode.
So the system returns automatically to AUTO
mode.

43Frequently asked questions

Reducing consumption / Fuel



Question



Answer


How can I optimise my 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 which allows the recovery of "free" energy for charging
the battery (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Why 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 (100% electric running) 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.
Why does the fuel consumption histogram sometimes
display consumption of 28 mpg (10 litres/100 km) in
town? In traffic jams, the fuel consumption graph may temporarily display high values but, as the
distance covered is low, this has very little impact on the average fuel consumption.
In urban driving, your Hybrid4 will remain more efficient in terms of fuel consumption
compared to a conventional vehicle.
Why 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 of energy when decelerating.
Why are there so may fuel alert messages when
starting to use the reser ve? To encourage you to refuel as soon as possible and to avoid loosing the possibility of all
electric running.
