Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items at the back of the boot, as
close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce 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 your summer tyres.
Obser ve the recommendations on
maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-

b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan.
Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule. When filling the tank, do not continue after the
3
rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900
miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a
consistent average.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. Visit a CITROËN dealer or
a

qualified workshop as soon as possible to
bring your vehicle's nitrogen oxides emissions
back in line with regulations.

must be reinitialised ever y time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a
drop in the inflation pressure of one
or more tyres.
Under-inflation detection 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):
-

The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section. Checking tyre pressures
This check should be done when the tyres
are "cold" (vehicle stopped for 1
hour or
after a
journey of less than 6 miles (10 km)
at moderate speeds).
Other wise, add 0.3

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The alert is kept active until the system is
reinitialised.Reinitialisation
The system must be reinitialised after any
adjustment to the pressure of one or more
tyres, and after changing one or more wheels.
F

U

sing a

compressor, such as the one in the
temporary puncture repair kit, check the
pressures of the four tyres when cold. Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written
on the tyre pressure label.
Check the pressures of the four tyres
before performing the reinitialisation.

Practical information

191
During the 30 minutes after topping up the
o il, the check per formed with the oil level
indicator in the instrument panel when the
ignition is switched on is not valid.
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.
Engine coolant
Check the engine coolant level
regularly.
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.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
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.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.

F

A

fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
Cooling of the engine when stopped
The engine cooling fan may star t 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 screenwash fluid must be topped up with
a ready for use mix.
In winter (temperatures below zero), a liquid
containing an anti-freeze agent must be
used which is appropriate for the prevailing
conditions, in order to preser ve the elements of
the system (pump, tank, ducts, etc.).
Filling with pure water is prohibited
under all circumstances (risk of freezing,
limestone deposits, jets, etc.).
Diesel fuel additive (Diesel
with particle filter)
or The minimum level in the particle
filter additive tank is indicated by fixed
illumination of this warning lamp,
accompanied by an audible warning
and a
message warning that the level
of additive is too low.
To p p i n g u p
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.

Headlamps and lamps
The headlamps have polycarbonate
lenses with a protective coating.
Do not clean them with a
dry or abrasive
cloth, nor with detergent or solvent
products.
Use a
sponge and soapy water.
The use of a
high pressure jet wash for
cleaning the headlamps, lamps and their
surrounds may damage the lacquer and
seals.
Observe the recommendations on
pressure and distance for jet washing.
First clean persistent stains with a
sponge
and warm soapy water.
Leather
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Refer to your vehicle's Maintenance and
Warranty guide for information on all the
special precautions to observe.
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of 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
17


litres.
Its capacity allows a

driving range of
approximately 5,600

miles (9,000 km), highly
dependent on your driving style.
An alert system is triggered automatically once
the reser ve level is reached: you can then drive
for a

further 1,500

miles (2,400 km) before the
tank is empty.
Driving with under-inflated tyres 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 per formance 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.
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.
Advice on care and maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
