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).

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.

Ease of use and comfort
Rear seats

Backrest angle

► Turn the knob to adjust the backrest angle.
Adjustable armrest

► Raise or lower the armrest.
► Turn the knob, located under the end of the
armrest, to lock it in the desired position.
Heated seat

Use this control to switch the heating of the seat
on or off.
Do not use the function when the seat
is not occupied.
Reduce the heating intensity as soon as
possible.
When the seat and passenger compartment
have reached a satisfactory temperature,
switch the function off; reducing electricity
consumption in turn decreases fuel
consumption.
Prolonged use of heated seats is not
recommended for people with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (illness, taking
medication, etc.).
To keep the heated pad intact and to prevent
a short circuit:
– Do not place heavy or sharp objects on the
seat.
– Do not kneel or stand on the seat.
– Do not spill liquids onto the seat.
– Never use the heating function if the seat
is damp.
Seat with adjustable shock
absorption


► Turn the knob to adjust the shock
absorption according to the driver’s weight.
Swivelling seat

► Press the control to rotate the seat 180°.
Two-seat front bench seat
It is equipped with two head restraints and two
seat belts.
Writing table

The central seat backrest folds to form a writing
table.
► Pull the strap located at the top of the
backrest cushion.

68
Driving
When the battery is in standby mode,
access to the vehicle is only possible by
unlocking the mechanical lock on the driver's
side door.
After a battery standby, the information (time, date, radio stations, etc.) is
memorised.
To remove the battery from standby mode:
► Turn the key to the MAR - ON position.
► Start the vehicle normally ( AV V position).
Parking brake
Application
► Apply the parking brake to immobilise the
vehicle.
► Check that the parking brake is correctly
applied before leaving the vehicle.
Apply the parking brake only when the
vehicle is stationary.
When parking on a slope, turn your
wheels towards the kerb and pull the
parking brake lever up.
There is no advantage in engaging a gear
after parking the vehicle, particularly if the
vehicle is loaded.
In the event of a failure of the
hydraulic braking system
While driving , to avoid any accidental
movement of the vehicle, use the parking
brake while depressing the brake pedal.
In this exceptional circumstance, it is
advisable to pull the parking brake up gently
so as not to block the rear wheels - risk of
skidding!
Release

► Pull the lever up gently and press the button
to release the parking brake.
When the vehicle is being driven, this
warning lamp coming on indicates that
the parking brake is still applied or has not been
fully released.
Manual gearbox
To change gear easily, always fully depress the
clutch pedal.
To prevent the mat from becoming caught under
the pedal:
– ensure that the mat is positioned correctly,
– never fit one mat on top of another.
Avoid leaving your hand on the gear knob as
the force exerted, even if slight, may wear the
internal components of the gearbox over time.
Engaging reverse gear

► Lift the ring under the knob to engage reverse
gear.
Never engage it until the vehicle has
come to a complete stop.
The movement must be done slowly to reduce
the noise when engaging reverse gear.
If fitted to the vehicle, the parking
sensors are activated when reverse gear
is engaged; an audible signal sounds.
For more information on the Parking
sensors, refer to the corresponding section.
Gear shift indicator
Depending on version or engine, this system
reduces fuel consumption by recommending a
higher gear change.
Gear shift recommendations should not be
considered compulsory. In fact, the road layout,
the traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued by
the system.
The system cannot be deactivated.
Operation
The information appears in the instrument panel screen in the form of the SHIFT
indicator, accompanied by an upward arrow to
signal to the driver that they can change up.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never recommends engaging first
gear or reverse, or changing down.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,

Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
To deactivate/reactivate the function:




► Press the button.
A message in the instrument panel confirms the
change of status.
When the function is deactivated, the indicator
lamp is lit; if the engine was in standby, it restarts
immediately.
To allow continuous operation of the air conditioning, deactivate the Stop & Start.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
any risk of injury caused by the engine
restarting automatically.
Driving on flooded roads
Before entering into a flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving
recommendations, particularly on flooded
roads, refer to the corresponding section.
Going into engine STOP
mode
With the vehicle stationary, place the gear lever
in neutral and release the clutch pedal.
This indicator lamp comes on in the instrument panel and the engine goes into
standby.
Automatic engine shutdown is only possible when the speed of the vehicle
has exceeded 6 mph (10 km/h), to avoid
repeated engine shutdowns when driving
slowly.

71
Driving
6This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running,
foot on the brake,
– the gradient of the road must be steeper than
5%,
– uphill, the gearbox must be in neutral or in a
gear other than reverse,
– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,
without using the parking brake, you have
approximately 2 seconds to move off before the
vehicle starts to roll back.
During the moving off phase, the function is
deactivated automatically, gradually releasing
the braking pressure. During this phase, you
may hear the typical mechanical brake release
noise, signalling the imminent movement of the
vehicle.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to get out of the vehicle with
the engine running, apply the parking brake
manually then ensure that the parking brake
indicator lamp is on.
Hill start assist is deactivated in the following
situations:
– when the clutch pedal is released,
– when the parking brake is applied,
– when the engine is switched off,
– if the engine stalls.
Malfunction
If a malfunction of the system occurs, this
warning lamp lights up, accompanied by
an audible signal and confirmed by a message
on the display. Have the system checked by a
CITROËN dealer or a qualified workshop.
Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the pressures
of the four tyres, as soon as the vehicle is
moving.
A pressure sensor is located in the valve of each
tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
The under-inflation detection system does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding,
– lengthens braking distances,
– causes premature wear of the tyres,
– increases fuel consumption.

AdBlue® (BlueHDi
engines)


To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Diesel fuel filter
The Diesel fuel filter is located under the bonnet,
close to the brake fluid reservoir.
If this warning lamp comes on, the filter
must be purged to remove water.
You can also purge the fuel filter regularly, every
time the engine oil is changed.
Bleeding the water in the filter

► Couple a clear hose to the bleed screw
1head.
► Place the other end of the clear hose in a
container.
► Loosen bleed screw 2.
► Switch on the ignition.
► Wait for the scavenge pump to stop.
► Switch off the ignition.
► Tighten bleed screw 2.
► Remove, then drain the clear hose and the
container.
► Start the engine.
► Check that there are no leaks.
HDi engines make use of advanced
technology. Any intervention requires a
special qualification guaranteed by the
CITROËN dealer network or a qualified
workshop .
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer

AdBlue® (BlueHDi
engines)


To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
® is contained in a special tank
holding about 19 litres.
It has an external filler neck, located in the fuel
filler flap under the filler neck of the fuel tank,
closed by a blue cap.
Its capacity allows a driving range of
approximately 3,700 miles (6,000 km) ( which
may vary considerably depending on the
driving style and the type of vehicle).
An alert system is triggered when the remaining
range reaches 1,500 miles (2,400 km), i.e. once
the reserve level has been reached.
Once the AdBlue® tank is empty, a
system required by legislation prevents
starting of the engine.
If the SCR system is defective, the level of
emissions from your vehicle will no longer
meet the Euro 6 standard: your vehicle
becomes polluting.
In the event of a confirmed fault with the SCR
system, you must go to a CITROËN dealer
or a qualified workshop as soon as possible:
after travelling a distance of 250 miles (400
km), a system will be triggered automatically
to prevent engine starting.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
– Use only AdBlue
® fluid that meets the ISO
22241 standard.
– Never transfer AdBlue
® to another container
as it would lose its purity.
– Never dilute AdBlue
® with water.
It is possible to obtain AdBlue
® from a CITROËN
dealer or a qualified workshop.
You can also visit a service station equipped with AdBlue® pumps specially
designed for passenger vehicles.
Recommendations on storage
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
