The rechargeable hybrid technology combines
two sources of energy: that of the petrol engine
and that of the electric motor, which drive the
front wheels (traction).
The engine and the motor can operate
alternately or simultaneously, according to the
driving mode selected and the driving conditions.
The electric power alone provides the mobility
of the vehicle in Electric mode, and in Hybrid
mode in case of moderate demand. It assists the
petrol engine during starting and acceleration
phases.
The electric power is supplied by a rechargeable
traction battery.

Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
Optimise your use of the gearbox
With an automatic gearbox, favour automatic
mode. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift indicator prompts you to engage
the most suitable gear. Whenever this indication
is displayed on the instrument panel, follow it
straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of electrical equipment
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31
mph (50 km/h), close the
windows and leave the air vents open. Consider using equipment that can help keep
the temperature in the passenger compartment
down (e.g.
sunroof blind, window blinds).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat as soon as possible.
Adapt the use of headlamps and/or foglamps
depending on visibility conditions.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving.
As a passenger, avoid connecting your
multimedia devices (e.g. film, music, video
game) to help reduce the consumption of energy.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle. Place the
heaviest items in the boot as close as possible to
the rear seats.
Limit the loads carried in the vehicle and
minimise wind resistance (e.g.
roof bars, roof
rack, bicycle carrier, trailer). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Comply with the servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
–

before a long journey
.
–

at each change of season.
–


after a long period out of use.
Do not forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).
Optimising the driving range
(rechargeable hybrid vehicles)
Connect the vehicle as soon as possible.
Favour the ECO zone of the power indicator by
driving smoothly and at a steady speed.
Anticipate slowing down as much as possible
and, if possible, favour decelerations with
regenerative braking mode activated (power
indicator in the CHARGE zone).
With the vehicle connected, carry out
temperature pre-conditioning before setting off.
To optimise consumption during a journey:

Instruments
Information to the driver
Instrument panel
The instrument panel contains all the information
required by the driver on the status of the
vehicle's various systems.
This information appears in the form of indicator
lamps, indicators and messages.

digital panel.
E-HUD
Depending on version, driver information also
appears in the extended head-up display.
For more information on E-HUD, refer to the
corresponding section.
Digital instrument panel
The digital instrument panel can be personalised
using a page system.
Depending on the page displayed, certain
information is hidden or presented differently.

Information displayed on
the instrument panel
The information displayed on the instrument
panel (e.g.
warning lamps, indicators) may have
a fixed or variable location depending on the
page or the driving aid activated.
For the functions that have indicator lamps for
both operation and deactivation, there is only
one dedicated location.

12
Instruments
Settings
Brightness adjustment is available after
activation of the function.
The system status and settings are memorised
when the ignition is switched off.
Activation/Deactivation
It can be activated/deactivated in the
Settings > Brightness touch screen
application.
►

With the ignition on, press the “ Head-Up
Display

” button to change the function status
(confirmed by the slider moving to the right/left:
function activated/deactivated).
Brightness adjustment
Brightness adjustment is configured in the
Settings > Brightness touch screen
application.
►

With the ignition on, press or move the slider
to the desired setting.
Adjusting the height



► With the ignition on and the control in the
central high position, move the control up/down
to adjust the desired height of the display
.
Warning and indicator
lamps
Displayed as symbols, the warning and indicator
lamps inform the driver of the occurrence of a
malfunction (warning lamps) or of the operating
status of a system (operation or deactivation
indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.
For more information on a system or a function,
refer to the corresponding section.
Persistent warning lamp
If a red or orange warning lamp comes on, there
may be fault which needs further investigation.
If a lamp remains lit
The references (1), (2) and (3) in the warning
and indicator lamp description indicate whether
you should contact a qualified professional in
addition to the immediate recommended actions.
(1): You must stop the vehicle
.
Stop as soon as it is safe to do so and switch off
the ignition.
(2): Contact a CITROËN dealer or a qualified
workshop.
(3): Visit a CITROËN dealer or a qualified
workshop.
