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).

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.
Reminder of the servicing
information
To access the service indications at any
time, briefly press the MODE button.
Use the up/down arrows to view service intervals
and engine oil quality.
Pressing the MODE button again allows you to
return to the various display menus.
A long press allows you to return to the home
screen.

Coolant temperature

If the needle is positioned between C (Cold)
and H (Hot): normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to the red
graduations.
If the needle enters the red zone or if the
warning lamp lights up:
► stop immediately, turn the ignition off. The
cooling fan may continue to run for a while, up to
approximately 10 minutes.
► wait for the engine to cool down to check the
level and if necessary, top it up.
In case of topping up
Be careful, the cooling circuit is under pressure!
To avoid any risk of burns, take a cloth and
unscrew the cap two turns to relieve the
pressure.
When the pressure has dropped, check the level
and remove the cap to top up.
If the needle remains in the red zone,
contact a CITROËN dealer or a qualified
workshop.

Safety
Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically every
time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by the flashing of this warning lamp on the instrument panel.
Deactivation
This system cannot be deactivated by the driver.
Malfunction
The lighting of this warning lamp, accompanied by an audible signal and
confirmed by a message on the instrument panel
display, indicates a malfunction of the DSC
system.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Anti-slip regulation (ASR)
Deactivation / Reactivation
The ASR system is activated automatically every
time the vehicle is started.
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
Electronic stability control
(ESC)
Electronic stability control (ESC: Electronic
Stability Control) integrating the following
systems:
– anti-lock braking system (ABS) and electronic
brake force distribution (EBFD),
– emergency braking assistance (EBA),
– wheel anti-slip regulation (ASR) or traction
control,
– dynamic stability control (DSC).
Definitions
Anti-lock braking system (ABS) and
Electronic brake force distribution
(EBFD)
This system improves the stability and handling
of your vehicle when braking and contributes
towards improved control on bends, in particular
on poor or slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
Emergency braking assistance (EBA)
In an emergency, this system enables you
to reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance. It is triggered in relation to the speed at which
the brake pedal is depressed. The effect of this
is a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip, by acting on the brakes of the driving
wheels and on the engine. It also improves the
directional stability of the vehicle on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed
by the vehicle and that required by the driver, the
DSC monitors each wheel and automatically acts
on the brake of one or more wheels and on the
engine to return the vehicle to the required path,
within the limits of the laws of physics.
Anti-lock braking system (ABS) and electronic brake
force distribution (EBD)
If this warning lamp comes on,
accompanied by an audible signal and a
message in an instrument panel screen, it
indicates a fault with the anti-lock braking system
(ABS) which could result in loss of control of the
vehicle when braking.
If these warning lamps come on,
accompanied by a message in the
instrument panel screen, it indicates a fault with
the electronic brake force distribution (EBFD)
system which could result in loss of control of the
vehicle when braking.
You must stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a
qualified workshop.
For maximum braking efficiency, a
bedding-in period of around 300 miles
(500 kilometres) is needed. During this
period, it is advisable to avoid any sudden,
repeated and prolonged braking.
The ABS does not provide shorter braking distances. On very slippery
surfaces (ice, oil, etc.) the ABS may extend
braking distances.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
For emergency braking, press the
brake pedal very hard and do not
release it, even on a slipper surface; you
will then be able to continue steering the
vehicle to avoid an obstacle.
After an impact, have these systems checked by a CITROËN dealer or a
qualified workshop.

Practical information
Topping up the engine oil level

► Remove the dipstick before topping up.
► Recover the oil filler neck.
► Unscrew the filler cap.
► Install the oil filler neck in the filler hole.
► Top up with oil.
► Remove the oil filler neck from the filler hole.
► Replace the filler cap.
► Replace the dipstick.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pad wear.
The Diesel circuit is under very high pressure.
All work on this circuit must be carried out
only by a CITROËN dealer or a qualified
workshop.
Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
If the engine cover is to be removed /
refitted, handle it with care to avoid
damaging the mounting clips.
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and
pull it out completely.
► Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A (max)
and B (min).
Do not start the engine if the level is:
– above mark A: contact a CITROËN dealer or a
qualified workshop.
– below mark B: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for the engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your CITROËN dealer and
qualified workshops).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.

Practical information
7Topping up the engine oil level

► Remove the dipstick before topping up.
► Recover the oil filler neck.
► Unscrew the filler cap.
► Install the oil filler neck in the filler hole.
► Top up with oil.
► Remove the oil filler neck from the filler hole.
► Replace the filler cap.
► Replace the dipstick.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.
Power steering fluid
The level of this fluid should be close to the "MAX" mark. Check it, with the
vehicle parked on level ground and with the
engine cold, by reading the level on the filler
neck.
Unscrew the cap secured to the dipstick. To
access the reservoir cap, remove the protective
cover by turning its three fixing screws a quarter
turn, then remove the second cover placed on
the cap.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the
"MAX" mark but should never exceed it.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.


To gain access to the tank cap, remove the
protective cover by turning its three fixing screws
a quarter of a turn.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Check the coolant level regularly
according to the use of your vehicle
(every 3,000 miles (5,000 km) / 3 months).
