"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.

Special conditions for the operation of ZEV mode



ZEV
mode can be selected when all of
the conditions for its operation are met, in
particular an adequate state of charge of the
battery (50% at least).
In the situations described below, the HDi
Diesel must be running; accordingly, ZEV

mode cannot be selected or is deactivated
automatically. The mode selector remains at or
returns to the AUTO
position to allow starting of
the HDi Diesel engine.


- Manual gear change when in automatic
mode using the steering mounted controls
for the electronic gearbox.
Cases of non availability of ZEV mode or automatic return
to AUTO mode

- Selection of manual mode by moving the
gear selector for the electronic gearbox to
position M
.

- Sustained and sharp acceleration.

- Use of demisting / defrosting.

- Intensive use of air conditioning.



Action by the driver:

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.

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.

Access to the underbonnet

The alternator-starter motor of your Hybrid4
vehicle is also supplied at high voltage.
If the vehicle ignition has not been switched off,
there is a risk of the engine restarting at any
time.
Always ensure that the
ignition is switched off
( READY
lamp off) before
opening the bonnet.

Before doing anything under the
bonnet, you must switch off the ignition
and verify that the READY
lamp in the
instrument panel is off - risk of serious
injury!



Recommendations

When immobilising the vehicle, with the
Hybrid4 system active, you must place
the gear selector in neutral N
.
Before carrying out any work in the
engine compartment, check that the
gear selector is in position N
, that the
parking brake is applied and that the
READY
lamp is off before switching off
the Hybrid4 system.

Six-speed electronic gearbox which offers a
choice between two operating modes:


- automated
mode for automatic control of
the gears by the gearbox,

- manual
mode for sequential gear changing
by the driver.
In automated mode, it is possible to change
gear manually by using the steering mounted
control paddles as desired, when overtaking,
for example.
