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.
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.
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 19 mph (30 km/h) when traffic is flowing
smoothly.
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.
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.
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).

Brightness of the
instruments and controls
The brightness of the instruments and
controls can be adjusted using the MODE
button, with the sidelamps on.
For more information on Vehicle configuration
(MODE), refer to the corresponding section.
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.

Driving
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar.
Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away
from the radar, sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
► ensure that the mat is secured correctly,
► never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Speed Limit recognition
and recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .




Using the camera located at the top of the
windscreen, this system detects the following
types of signs and displays the corresponding
information on the instrument panel:
– the maximum authorised speed,
– no overtaking,
– the end of the previous limitations /
restrictions.

77
Driving
6Selecting the function
► Turn ring 1 all the way down. The speed
limiter is selected, but is not yet active.


The display indicates OFF and the last
programmed speed.
Programming a speed
A speed can be programmed without activating
the speed limiter but with the engine running.
To memorise a speed higher than the previous
one:
► Move the control upwards (+).
A short press increases the setting by 1 mph
(km/h).
Pressing and holding increases the setting in
steps of 5 mph (km/h).
To memorise a speed lower than the previous
one:
► Move the control downwards (-).
A short press decreases the setting by 1 mph
(km/h).
Pressing and holding decreases the setting in
steps of 5 mph (km/h).
Activation/Deactivation
► Press button 2 to activate the speed limiter.

OFF disappears from the display and a message
appears confirming activation.


Pressing again deactivates it, OFF is displayed
again and a message appears confirming
deactivation.
Exceeding the programmed
speed
► Press firmly on the accelerator pedal, going
beyond the point of resistance, to exceed the
programmed limit speed.


The speed limiter is deactivated temporarily and
the programmed speed flashes.
To return to the speed limiter function, reduce
your speed below the programmed speed.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the programmed speed.
Switching the function off
► Place the ring in the central position O or
switch the ignition off to stop the system.
The last programmed speed remains in the
memory.
Malfunction

The programmed speed is cleared, then
replaced by dashes.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Fixed speed limiter

If your vehicle is equipped with it, the speed of
your vehicle can be limited in a fixed way to 56
mph (90 km/h) or 62 mph (100 km/h).
A label located in the passenger compartment
indicates this maximum speed.
The fixed speed limiter is not a cruise control
type function. It cannot be activated or
deactivated by the driver during the trip.

78
Driving
The maximum speed is set according to the regulations in force in the country of
sale.
This maximum speed cannot be changed by
the driver.
If you wish to modify this maximum speed,
contact a CITROËN dealer.
Cruise control - particular
recommendations
For the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
The speed setting can be exceeded
temporarily by pressing the accelerator
pedal (the programmed speed flashes).
To return to the speed setting, release
the accelerator pedal (when this speed is
reached again, the display of the speed stops
flashing).
Operating limits
Never use the system in the following
situations:
– In an urban area with the risk of
pedestrians crossing the road.
– In heavy traffic.
– On winding or steep roads.
– On slippery or flooded roads.
– In poor weather conditions.
– Driving on a speed circuit.
– Driving on a rolling road.
– When using snow chains, non-slip covers
or studded tyres.

Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
System which detects the involuntary crossing of
longitudinal traffic lane markings on the ground
(solid or broken line).


A camera, fitted in the upper central part of the
windscreen, monitors the road and detects the
lane marking lines and the position of the vehicle
in relation to them.
With the speed of the vehicle above 37 mph (60
km/h), an alarm is triggered if there is a deviation
in direction.
This system is particularly useful on motorways
and main roads.
In case of windscreen damage, it is strongly
recommended to contact a CITROËN dealer or
a qualified workshop for any replacement and
calibration of the camera.
Operation
The system starts automatically when moving
off.
A check of the operating conditions takes place: these two indicator
lamps come on in the instrument panel.
When these conditions are met, these two
indicator lamps go off. The system is activated.
If the operating conditions are not met, the
system is activated but is no longer effective.
This is signalled by the fixed illumination of these
two warning lamps in the instrument panel.
Operating conditions
Once engaged, the system is active only when
these operating conditions are met:
– The vehicle is moving forwards.
– No malfunction of the vehicle is detected.
– The speed of the vehicle is equal to or greater
than approximately 37 mph (60 km/h).
– The longitudinal marking of the traffic lanes is
clearly visible.
– The visibility conditions are clear.
– The trajectory is in a straight line (or in the
case of bends, they are wide).
– The field of vision is sufficiently clear (the
safety distance with the vehicle ahead is
respected).
– In the event of a lane departure, the direction
indicator corresponding to the direction (right or
left) of the departure has not been operated.
