Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
Oil filter
Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Brake disc wear
For any information on checking the brake
disc wear, contact a CITROËN dealer or a
qualified workshop.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer or a qualified workshop.
If this warning lamp comes on,
have the brake pad wear checked
by a CITROËN dealer or a
qualified workshop. In order to avoid damaging the
electrical units, we strongly advise you
not to use high pressure washing to clean
the engine compartment.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes. Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
Change the filter regularly, in accordance
with the manufacturer's servicing schedule.

A nd AdB L u E® AddItIVE
AdBlue® is the brand name of the solution
needed for operation of the SCR system.
BlueHDI vehicles have a specific AdBlue
®
additive tank with a capacity of 15 litres.
It has an exterior filler located behind the
fuel filler flap below the fuel filler cap and
closed with a blue filler cap.
The objective of BlueHDi is to reduce by
up to 90% the emissions of NOx (nitrous
oxides) in the air, using a system that
converts NOx into water vapour and nitrogen
in a dedicated catalytic converter: SCR
(Selective Catalytic Reduction).
This objective meets the "Euro 6" emissions
standard adopted by the European Union
aimed at limiting the emissions of pollutants
from internal combustion engines.
The SCR technology used on BlueHDi
engines involves the injection of AdBlue
®
fluid into the exhaust system. This operation can also be carried out
by a CITROËN dealer or a qualified
workshop.
Scr technology
Filling of the AdBlue® tank can be done
using:
-

5 or 10 litres containers equipped with a

10 centimetre filler tube or the filling kit
available from CITROËN dealers,
-

1.89 litre botles that are screwed onto

the filler neck, available from CITROËN
dealers,
-

or when at a fuel filling station equipped

with a special AdBlue
® delivery pump for
heavy or light vehicles.
AdBlue® additive

137
Good practice
While the quantity of AdBlue® in the additive
tank
is sufficient, no information is displayed.
On the other hand, once the additive level
drops to the quantity needed for a range
of 1 500 miles (2 400 km) driving, you
are warned by different temporary signals
(warning lamp, message, audible signal).
As more miles are covered, these signals
intensify and the message becomes
permanent.
Filling the additive tank
For light vehicles, 5 or 10 litre containers
and 1.89 litre (1/2 US gallon) bottles are
available from CITROËN dealers.
If you want to fill the AdBlue
® tank yourself,
ensure that you have a suitable filler pipe,
which may or may not be supplied with the
additive container. When the AdBlue® tank is empty,
restarting becomes impossible.
It is strongly recommended that you do
not wait for the successive alerts before
topping-up the AdBlue
® tank, but do this as
soon as possible.

CHECKS

refit the filler cap
-
Refit the blue cap to the tank and turn it

a 6
th of a turn clockwise, to its stop.
-

Close the filler flap.
Never dispose of

AdBlue
® additive
bottles in the household waste. Place
them in a special container provided this
purpose or take them to your dealer.
Keep AdBlue
® out of the reach of
children, in its original container.
Never transfer AdBlue
® to another container:
it would loose its purity.
Never dilute the additive with water.
Never pour the additive into the Diesel fuel
tank.
recommendations on storage
Never store containers or bottles of
AdBlue® in your vehicle. Freezing of the AdBlue
® additive
AdBlue® freezes at about -11°C
(12.2°

F) and deteriorates above 25°C
(77°F).
It is recommended that containers and
bottles be stored in a cool area and
protected from direct sunlight.
Under these conditions, the additive can be
kept for at least a year.
Additive that has been frozen can be used
once it has thawed out in ambient air. The SCR system includes an AdBlue
®
tank heater that ensures operation of
the vehicle in normal conditions.
In exceptional situations, such as when the
vehicle is kept at temperatures below -15°C
(5°F) for a long period, there may be an
emission fault alert related to freezing of the
AdBlue
® additive.
Park the vehicle in an area at a more
moderate temperature for a few hours until
the additive becomes a liquid again.
The emissions warning lamp does not go off
immediately, but does so after a few miles
of driving.

Access to the battery
Unscrew the 6 access cover retaining
screws.
Lift off or remove completely the access
cover.
Press lever 1 downwards to spread the
clamp.
Remove the terminal 2 from the negative (-)
post. The batteries contain harmful
substances such as sulphuric acid and
lead. They must be discarded in accordance
with the provisions of the law and must not,
in any circumstances, be discarded with
household waste.
Take used batteries to a special collection
point.
The charging operation must be carried
out in a ventilated area away from
naked flames or any possible sources of
sparks to eliminate the risk of explosion and
fire.
Do not attempt to charge a frozen battery: it
must first be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist
who will check that the internal components
have not been damaged and that the
container is not cracked, which could mean
that there is a risk of a leak of toxic and
corrosive acid.
Proceed with a slow charge charge at low
current for a maximum pf about 24 hours to
avoid damaging the battery. Before disconnecting the battery, you must
wait for 2 minutes after switching off the
ignition.
Never disconnect a terminal when the
engine is running.
Never charge a battery without first
disconnecting the terminals.
Close the windows and doors before
disconnecting the battery.
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If slight difficulties
are experienced after this, please contact a
CITROËN dealer or a qualified workshop.
