2016 Citroen DS5 HYBRID heating

9Hybrid4 system

When the Hybrid4 system is
started, this indicator lamp
comes on to signal that the
vehicle is ready to move off.

Illumination of this indicator lamp is more or
less instant but may take a few seconds in
some cases (pre-heating the HDi Diesel engine
in cold weather or in energy economy mode...).






READY lamp


Never leave the Hybrid4 system on
when leaving the vehicle, or opening
the bonnet, refuelling...
Before leaving the vehicle, ensure that
the READY
lamp is off.
This allows the high voltage battery to be
recharged using "free" energy
which can then
be reused
for future energy requirements.


CHARGE zone
POWER zone

Indicates an increased cumulative power
demand
from your vehicle, taking account
of the combined power available from the
HDi Diesel engine and the electric motor.















Power indicator

The indicator dial displays information on the total power used in real time, combining electric and
Diesel.
It comprises three operating zones.
Indicates that the vehicle
is optimising its energy
consumption
, electric, Diesel
or a combination of both.

ECO zone

This zone corresponds to phases of electric
running as well as to phases of optimum use
of the HDi Diesel engine, which are easily
accessible with a suitable driving style (smooth
"eco-citizen" driving).
Indicates that the vehicle is in
an electrical energy recovery

phase: on deceleration, braking
(partially) or particularly with
your foot off the accelerator.

Starting the Hybrid4 system


Activation of the Hybrid4 system

On activation of the Hybrid4 system, the
instrument panel lights up, the power indicator
needle is placed at position " 0
". The steering
column automatically unlocks (perceptible
noise and movement of the steering column).
Depending on certain parameters, such as the
state of charge of the high voltage battery or
the ambient temperature, the Hybrid4 system
itself determines whether it is necessary to
start the HDi Diesel engine.
The mode selector is at the AUTO
position.

In wintry conditions with the
engine cold, the Diesel pre-
heating warning lamp can stay
on for a few seconds; wait until
it goes off before releasing the
brake pedal.






























Starting - switching off the Hybrid4 system


Never leave children alone inside the
vehicle when the Hybrid4 system is
active.

Place the gear selector at position N
.

)
Insert the electronic key in the reader.
or


)
With Keyless Entry and Starting, simply
having the electronic key inside the vehicle
is sufficient.
)
Press the brake pedal firmly.


)
Make a single short press (about one
second) on the " START/STOP
" button.

)
Maintain pressure on the brake pedal until
the READY
lamp comes on, signalling
activation of the Hybrid4 system, confirmed
by an audible signal.

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


The READY
lamp may come on after
a few seconds if there is a demand
for activation of the Hybrid4 system
after energy economy mode has been
entered.

"ECO OFF" function


This function prevents the HDi Diesel engine being
switched off and ensures that a comfortable temperature
can be maintained in the passenger compartment.
This therefore allows the air conditioning or heating to be
kept running.
Depending on version, the control is either in
the switch panel alongside the steering wheel,
or in the " Driving
" menu of the touch screen.

On pressing the ECO OFF
switch, the
HDi Diesel engine restarts immediately and
then operates continuously.
The indicator lamp in the control comes on.

Pressing this control again deactivates the
function.
The indicator lamp in the control goes off.
The Hybrid4 system returns to normal
operation.

*
Except in ZEV mode, which gives preference
to electric running over maintaining a
comfortable temperature.
The function is deactivated on
switching off the ignition.
During phases of electric running and
when the internal combustion engine is
stopped, the Hybrid4 system manages
restarting automatically to maintain
the temperature in the passenger
compartment * .
However, variations in temperature
may still be felt in very high ambient
temperatures.
In this case, activate the ECO OFF

function.






With the switch on the dashboard



)
Press this switch.
Deactivation is confirmed by the illumination of
the indicator lamp in the control switch and the
display of a message.

Pressing the switch again reactivates the
system.
The indicator lamp in the switch goes off,
accompanied by the display of a message.




With the touch screen button


Pressing the button again reactivates the
system.
The indicator lamp for the button goes off,
accompanied by the display of a message.


)
Select the "Driving"
menu.
Deactivation is confirmed by the illumination of
the indicator lamp for the button and the display
of a message.

Driving recommendations


Obser ve the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
On a long journey, a break every two hours is
strongly recommended.
In difficult weather, drive smoothly, anticipate
the need to brake and increase the distance
from other vehicles.



Driving on flooded roads


We strongly advise against driving on flooded
roads, as this could cause serious damage
to the internal combustion engine or electric
motor, the electronic gearbox, or the electrical
systems of your vehicle. If you are obliged to drive through water:


- check that the depth of water does not
exceed 15 cm, taking account of waves
that might be generated by other users,

- place the mode selector in the 4WD

position,

- drive as slowly as possible without
stalling. In all cases, do not exceed 6 mph
(10 km/h),

- do not stop and do not switch off the
engine.
On leaving the flooded road, as soon as
circumstances allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.



Important!


Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Do not park or run the engine when
stationary in areas where inflammable
substances and materials (dry grass,
dead leaves...) might come into
contact with the hot exhaust system
or certain components of the Hybrid4
system which can reach very high
temperatures - Risk of fire!

Never leave a vehicle unsuper vised
with the engine running. If you have
to leave your vehicle with the engine
running, apply the parking brake
and put the electronic gearbox into
position N
.

29Hybrid4 system
This ventilation system does not operate at
the same speed at all times: it is continuously
adjusted to suit the cooling requirements of the
battery.
The noise of its operation can be heard,
particularly at the rear, after the Hybrid4 system
is switched off (post-ventilation).









Ventilation of the high voltage battery


Safety recommendations

Do not obstruct the air intake with
objects such as clothes or bags, in
order to avoid any risk of the battery
overheating, which could cause a loss
of per formance of the Hybrid4 system,
even damage to the battery.
Do not spill fluids, as this may damage
the battery and cause a short-circuit.






The high voltage battery has an air cooling
system.
This comprises an air intake (located on
the side of the left hand rear seat) and a fan
(located behind the left hand boot trim panel).

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.

Air conditioning / Heating



Question



Answer


It seems to me that the vehicle runs less on electric
when the heating or air conditioning is operating, is that
right? The demand for heating or air conditioning may require the starting of the HDi Diesel
engine until the desired level of comfort is attained.
Normal operation of the Hybrid4 system is simply put back. The period can be longer
under very low or very high ambient temperatures.
It seems to me that when it is very hot and the air
conditioning is working, the vehicle runs on electric for
shorter periods. Is that right? When it is hot, the periods when the HDi Diesel engine 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 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).

Miscellaneous



Question



Answer


Is towing possible with my Hybrid4 vehicle? For information on the towing ability of your Hybrid4 vehicle, refer to " Weights and towed
loads" in the "Technical data" section.
This allows a jet ski or two-wheeler on a trailer to be towed, for example.
This limit is related to maintaining adequate cooling capacity for the HDi Diesel engine as
well as the components of the Hybrid4 system that are also cooled by the engine's cooling
system.
Why does engine braking seem so strong? If the high voltage battery is not fully charged, the engine braking results mainly from the
energy recovery by the electric motor. The power of this engine braking is higher than that
of an internal combustion engine.
