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 a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
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.
Favour the use of “Eco” driving mode.
With an EAT8 gearbox, with the gear selector
in mode
D, and except in Sport mode, favour
"free-wheeling" by fully lifting your foot from the
accelerator pedal in order to save fuel. 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.
Avoid using Sport mode for too long, in order to
limit your energy consumption.
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.
With a BlueHDi Diesel engine, if the SCR system
is faulty, your vehicle will emit pollution. Visit
a CITROËN dealer or a qualified workshop
as soon as possible to restore your vehicle's
nitrogen oxide emissions to legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.

Eco-driving
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:
►

Programme a destination in the vehicle’
s
GPS navigation system.
►

Select the
Hybrid driving mode.
►

Make sure that the battery charge level is
close to maximum.
►


Do not use the e-Save function while driving.
►


Use the heating/air conditioning system
wisely

Driving
6partially recharge the traction battery, without
affecting the charge level indicator.
Progressive Hydraulic
Cushions
This suspension system with progressive hydraulic cushions improves driving comfort by
filtering out the imperfections and demands of
the road surface.
Each shock absorber is equipped with a
hydraulic compression stop (at the base) and a
hydraulic rebound stop (at the top).
Depending on the intensity of the shock to be
absorbed, these stops provide the vehicle with a
greater freedom of movement or gradually slow
down the amount of movement in order to avoid
any sudden jolts at the end of travel.
Unlike conventional suspension which absorbs
the energy but then partially returns some of it,
this active suspension absorbs and dissipates
this energy, without producing any rebound.
Driving modes
The number and type of driving modes available depend on the vehicle’s engine and equipment.
Driving modes are selected using one of the
following controls, depending on version:




1. Pressing the control activates Eco mode. The
indicator lamp comes on.
2. Pressing the control activates Sport mode.
The indicator lamp comes on.
3. Pressing the control displays the modes on
the instrument panel.
The selected mode is activated immediately.
With petrol / Diesel engines
Each time the ignition is switched on, Normal
mode is selected by default.
Eco
Reduces energy consumption by restricting the
performance of the heating and air conditioning
systems, although it does not deactivate them.
Normal
Restores the vehicle’s original settings.
Sport
Enables more dynamic driving with action on the
power steering, accelerator and gear changes
(with an automatic gearbox).
Depending on version, with an EAT8
gearbox and the selector in position D
(except Sport mode), fully releasing the
accelerator pedal allows free-wheeling which
can save fuel.
A drop in engine speed is normal (rev counter
at idle, drop in engine noise).
With rechargeable hybrid
engine
Each time the ignition is switched on, Electric
mode is selected by default.
Electric
Allows driving using 100% electrical energy.
The maximum speed is approximately 84 mph
(135
km/h).
When starting the vehicle, if the conditions do
not allow the activation or retention of Electric
mode, the message "Electric mode currently
unavailable" is displayed on the instrument
panel. The vehicle automatically changes to
Hybrid mode.
If a blue LED comes on under the interior rear
view mirror, visible from outside the vehicle, this
confirms that you are driving in Electric mode.
