Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise their
fuel consumption and CO
2emissions.
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 and avoid pressing the accelerator pedal
heavily or suddenly.
The gear efficiency 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 attitudes
help to save fuel, reduce CO
2 emissions and
decrease general traffic noise.
If the vehicle has the steering-mounted
"CRUISE" control, use cruise control at speeds
above 25 mph (40 km/h) when the traffic is flowing well.
Use electrical equipment wisely
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 (sunroof blind and window blinds, etc.).
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.
Switch off the headlamps and foglamps when
the visibility conditions do not require their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving.
As a passenger, avoid connecting your
multimedia devices (film, music, video game,
etc.) to help reduce consumption of electrical
energy, and hence fuel.
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 (roof bars, roof rack, bicycle carrier, trailer, etc.). 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 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 overlook the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (engine oil,
oil filter, air filter, passenger compartment filter,
etc.) and 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 regulatory
compliance.
When filling the fuel tank, do not continue after
the third nozzle cut-out, 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).

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.
Warning lamp continuously
lit
The illumination of a red or orange warning lamp
indicates the occurrence of a fault that needs
further investigation.

A few definitions…
Range
(miles or km)
The distance which can still be travelled with the fuel remaining in the tank (related
to the average fuel consumption over the last
few miles (kilometres) travelled).
This value may fluctuate if a change of driving style or terrain results in a
significant change in the current fuel
consumption.
Dashes are displayed when the range falls below
20 miles (30 km).
After filling with at least 5 litres of fuel, the range
is recalculated and is displayed if it exceeds 60
miles (100 km).
If dashes instead of figures continue to
be displayed when driving, contact a
CITROËN dealer or a qualified workshop.
Current fuel consumption
(mpg or l/100 km or km/l)Calculated over the last few seconds.
This function is only displayed above 20 mph (30 km/h).

Access
2Unlocking the vehicle

► With the electronic key on your person and in the recognition zone A, pass your hand behind
the door handle of one of the front doors to
unlock the vehicle or press the tailgate opening
control.
Flashing of the direction indicators for a
few seconds signals:
– the unlocking of the vehicle for versions without alarm,– the deactivation of the alarm for other versions.
For safety and theft protection reasons,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with you.
Accumulations (water, dust, grime, salt etc.) on the inner surface of the door
handle may affect detection.
If cleaning the inner surface of the door
handle using a cloth does not restore
detection, contact a CITROËN dealer or a
qualified workshop.
A sudden splash of water (stream of water,
high pressure jet washer, etc.) may be
identified by the system as the desire to open
the vehicle.
If one of the doors or the boot is still open
or if the electronic key for the Keyless
Entry and Starting system has been left inside the vehicle, central locking will be disabled.
However, if the vehicle is fitted with an alarm,
it will be activated after 45 seconds.
If the vehicle is unlocked but the doors or boot are not subsequently opened, the vehicle will automatically lock itself again after about 30 seconds. If the vehicle is fitted with
an alarm, it will also be reactivated
automatically.
As a safety measure, never leave the vehicle, even for a short time, without
taking the Keyless Entry and Starting
system’s electronic key with you.
Be aware of the risk of theft of the vehicle if
the key is present in one of the defined areas
while the vehicle is unlocked.
To preserve the battery charge in the electronic key and the vehicle's battery,
the "hands-free" functions are set to
hibernation mode after 21 days without use.
To restore these functions, press one of the
remote control buttons or start the engine with
the electronic key in the reader.
For more information on starting with the
Keyless Entry and Starting system, refer to
the corresponding section.
Electrical interference
The electronic key may not operate if
close to certain electronic devices: telephone
(switched on or on standby), laptop computer,
strong magnetic fields, etc.
Locking the vehicle
Normal locking

► With the electronic key in the recognition zone A, press with a finger or thumb on one of
