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).

Indicators
Service information
For a few seconds after the ignition is switched
on, the spanner symbolising service information
comes on: the screen informs you when the next
service is due, in accordance with the servicing
schedule indicated in the manufacturer's service
schedule.


This information is determined in relation to the
distance travelled since the previous service.
Engine oil level
Depending on the engine, the engine oil level is
then displayed, on a scale of 1 (Min) to 5 (Max).
If no scale is displayed, the oil level is
insufficient; it is essential to top it up to prevent
engine damage.
For the measurement of this level to be valid, the
vehicle must be parked on horizontal ground,
with the engine having been off for more than 30
minutes.
If in doubt, check the oil level using the
dipstick.
For more information on Checking levels,
refer to the corresponding section.


After a few seconds, the display returns to its
standard functions.
Engine oil quality
This warning lamp flashes and, if your vehicle is equipped with this function, a
message is displayed at each start: the system
has detected a deterioration of the engine oil. It
is essential to change the oil as soon as
possible.
This 2nd warning lamp, coupled with the
1st, lights up on the instrument panel if the
oil change has not been carried out, and the
degradation of the oil has exceeded a new
threshold. If this warning lamp comes on at

11
Instruments
1regular intervals, the oil has to be changed as
soon as possible.
For 3.0 L HDi engines, the engine speed
is then limited to 3,000 rpm, then 1,500
rpm until the oil is changed. Change the
engine oil to prevent damage.
Resetting the service
indicator
A qualified workshop, equipped with the
diagnostic tool, will stop the permanent flashing
of the warning lamp after each service.
If you have serviced the vehicle yourself, reset
the service indicator as follows:
► Insert the key into the ignition switch.
► Turn it to the MAR - ON position.
► Simultaneously depress the brake and
accelerator pedals for more than 15 seconds.
Refer to the checklist in the
manufacturer's service schedule
provided on delivery of the vehicle.

Safety
5General safety
recommendations
Do not remove the labels attached in
different places on your vehicle. They
include safety warnings as well as
identification information for the vehicle.
For all work on your vehicle, use a
qualified workshop that has the technical
information, skills and equipment required, all
of which a CITROËN dealer is able to
provide.
Depending on country regulations,
certain safety equipment may be
mandatory: high visibility safety vests,
warning triangles, breathalysers, spare bulbs,
spare fuses, fire extinguisher, first aid kit, mud
flaps at the rear of the vehicle, etc.
Installing electrical accessories:
– The fitting of electrical equipment or
accessories not approved by CITROËN may
cause excessive current consumption and
faults and failures with the electrical system
of your vehicle. Contact a CITROËN dealer
for information on the range of approved
accessories.
– As a safety measure, access to the
diagnostic socket, used for the vehicle's
electronic systems, is reserved strictly for
CITROËN dealers or qualified workshops,
equipped with the special tools required (risk
of malfunctions of the vehicle's electronic
systems that could cause breakdowns or
serious accidents). The Manufacturer cannot
be held responsible if this advice is not
followed.
– Any modification or adaptation not intended
or authorised by CITROËN or carried out
without meeting the technical requirements
defined by the Manufacturer will result in the
suspension of the commercial warranty.
Installation of accessory radio
communication transmitters
Before installing a radio communication
transmitter with an external aerial, you must
without fail contact a CITROËN dealer for
the specification of transmitters which can
be fitted (frequency, maximum power, aerial
position, specific installation requirements),
in line with the Vehicle Electromagnetic
Compatibility Directive (2004/104/EC).
Declarations of conformity for radio
equipment
The relevant certificates are available on the
http://service.citroen.com/ACddb/ website.

Practical information
A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
Screenwash and headlamp
washer fluid
To check the level or top up this fluid on
vehicles fitted with headlamp washers,
immobilise the vehicle and switch off the engine.
Reservoir capacity: approximately 5.5 litres.


To access the filler cap, pull the telescopic filler
neck and unclip the cap.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular on the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Passenger compartment
filter

Practical information
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
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
