Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
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. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift 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 practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of electrical equipment
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 (e.g.
sunroof blind, window blinds).
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.
Adapt your use of the headlamps and/or
foglamps to the level of visibility, in accordance
with current legislation in the country in which
you are driving.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving.
As a passenger, avoid connecting your
multimedia devices (e.g.
film, music, video
game) to help reduce the consumption of energy.
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 (e.g.
roof bars, roof
rack, bicycle carrier, trailer). 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 the 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 forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
has a fault, 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 legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, 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).

Practical information
7supplied with the vehicle (or available from
your CITROËN dealer or qualified workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►
Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
The oil level indication displayed on the instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the "MAX" mark. If not, check the brake
pads for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
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 level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the " MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant 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.
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.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible signal and a warning message.
Topping up
The topping up of this additive must be carried
out quickly.
Visit a CITROËN dealer or a qualified workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.

Practical information
7Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
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.
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 energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime. Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
AdBlue® (BlueHDi)
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 combines 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 17 litres.
Its capacity allows a driving range of
approximately 3,900
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
