2016 Citroen DS5 HYBRID ECO mode

"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.

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
.

Eco-driving

Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel
consumption and CO
2 emissions.

Adapted to your Hybrid4 vehicle


Use gear selector position A
, as this optimises gear changes to suit the circumstances, and
the AUTO
mode of the Hybrid4 mode selector.
When moving off, accelerate normally up to the desired speed ( POWER
zone between 20
and 40 %).
At steady speeds, drive gently with small movements of the accelerator pedal ( ECO
or
CHARGE
zone), to allow running in electric mode when driving at low speed.
Anticipate the need to slow down and use engine braking ( CHARGE
zone), so as to make
use of the recovery of "free" energy, while maintaining light pressure on the accelerator
pedal.

For information on other eco-driving practices, refer to the corresponding section of the
handbook for the vehicle.

Unsuitable circumstances:



- If the state of charge of the high voltage
battery is lower than 4 bars (equal to
50% charged). In AUTO
mode, electric
operation is possible with a lower state of
charge.

- When the speed of the vehicle exceeds
18 mph (30 km/h), if the internal combustion
engine has not already started at least once
since the Hybrid4 system was started.

- When the fuel level enters the reser ve
zone (illumination of the low fuel warning
lamp). Where this reser ve is is being used
up quickly, ZEV
may not be possible for
some time after refuelling.
- During phases of regeneration of the
particle filter (FAP), which is automatically
triggered approximately every 300 miles
(500 kms) for a period of about 10 minutes.
During regeneration of the particle filter,
the particles a brought up to a high
temperature using the HDi Diesel engine;
A message is then displayed: " Electric
mode not available: FAP regeneration
".



Maintaining the performance of
the system:


- If certain conditions or engine temperature
requirements needed by the HDi Diesel
engine are not met (for example, in wintry
conditions).

- Following a prolonged period with the
vehicle parked in the sun.

- When the state of charge of the high
voltage battery is close to the maximum
level (for example: when going down a long
hill using the electric motor for braking),
recovery of the vehicle's kinetic energy
being no longer possible, the HDI Diesel
engine restarts automatically just to
provide engine braking.

- On a steep rising slope.

- Driving at altitude.

Car washing machine or tunnel


Some car washing machines or tunnels (where the vehicle is moved for wards on a travelling track) require that the parking brake be "released" during
the wash.
With the Hybrid4 system active, READY
lamp on, parking brake
released:


)
Place the gear selector at position N
.

)
Switch off the Hybrid4 system (press the START/STOP

button). The READY
lamp goes off in the instrument panel
and the parking brake is applied automatically.

)
Switch on the ignition again (press the START/STOP
button)
without your foot on the brake pedal. The READY
lamp
remains off.

)
Release the parking brake using the manual control on the
centre console, while keeping your foot on the brake pedal.

)
Switch off the ignition (press the START/STOP
button without
your foot on the brake pedal) after having checked that the
parking brake remains released.



If the HDi Diesel engine was on standby, it then restarts.
If the HDi Diesel engine is running, its operation is maintained
without time limit.
With the Hybrid4 system active, READY
lamp on, parking brake
released:


)
Place the gear selector at position N
( AUTO
mode).

)
Press the brake pedal then the " ECO OFF
" button.



Car washing machines or tunnels in which the HDi
Diesel engine must be switched off.
Car washing machines or tunnels in which the HDi
Diesel engine must not be switched off.

If possible on your vehicle, deactivate the automatic operation of the electric parking brake in the vehicle systems configuration menu.

Recovery of the vehicle on a fl at-bed


Never recover the vehicle by towing it with two or four wheels on the ground, as there is a risk of
damage to the transmission.
However, if necessary because access to the vehicle is difficult, the vehicle can be moved a few
dozen metres, at a speed of less than 6 mph (10 km/h).

Use the towing eye only
to pull the vehicle out
or to lash it for recovery on a flat-bed lorry or
trailer.

Before doing any work, with the ignition on, press the brake pedal and place the gear selector at
position N
, then switch off the Hybrid4 system ( READY
lamp off).
Always call on professionals for recovery of the vehicle on a flat-bed lorry or trailer.









Snow chains


Recommendations


The use of snow chains is only authorised on
the front wheels.
The mode selector must be in the
4WD
position.

For information on the sizes
compatible with the tyres on your
vehicle and advice on use, refer to the
corresponding section in the handbook
for the vehicle.

Weights and towed loads (in kg)



*
The kerb weight is equal to the unladen weight + driver (75 kg).

**
The weight of the braked trailer can be increased, within the GTW limit, if the GV W of the towing vehicle is reduced by an equal amount; warning,
towing using a lightly loaded towing vehicle may have an adverse effect on its road holding.
To make use of the 300 kg load transfer, the driver must be alone in the vehicle with no luggage in the vehicle.

each additional 1 000 metres of altitude.
The maximum authorised speed is reduced when towing (comply with the legislation in force in your country).
High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine; if the ambient temperature is above 37 °C,
limit the towed load.

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.
