Checking levels
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).
Engine oil level
The check is carried out either when the ignition is switched on using the
o
il level indicator in the instrument
p
anel for vehicles with an electric oil
level
gauge, or using the dipstick.Checking using the dipstick
Refer to the "Petrol engine" or "Diesel engine" section for the location of the dipstick in the
e
ngine compartment of your vehicle.
F
T
ake the dipstick by its coloured grip and
r
emove it completely.
F
W
ipe the end of the dipstick using a clean
n
on-fluffy cloth.
F
R
efit the dipstick and push fully down, then
p
ull it out again to make the visual check:
t
he correct level is between the marks A
and
B.
It
is
normal
to
top
up
the
oil
level
between
t
wo
services
(or
oil
changes).
CITROËN
r
ecommends
that
you
check
the
level,
and
top
u
p
if
necessary,
every
3
000
miles
(5
000
kms).
Check
all
of
these
levels
regularly,
in
line
with
the
manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
If
a
level
drops
significantly,
have
the
corresponding system checked by a CITROËN dealer or a qualified workshop.
To
ensure
that
the
reading
is
correct,
y
our

Engine oil change
Refer to the manufacturer's service schedule for details of the interval for this operation.
In
order to maintain the reliability of the engine

Coolant level
The coolant level should be close to the "MA X" mark but should never

To
avoid
any risk of scalding, unscrew the cap

Changing the fluid
Refer to the manufacturer's service schedule f
or details of the interval for this operation.
Fluid specification
The brake fluid must conform to the manufacturer's r ecommendations. The cooling fan may star t after switching

AdBlue® additive and SCR system
f
or
BlueHDi Diesel engines
To assure respect for the environment and c
onformity with the new Euro 6 emissions
s
tandard, without adversely affecting the
p
er formance or fuel consumption of Diesel
e
ngines, CITROËN has taken the decision to
e
quip its vehicles with an effective system that
a
ssociates SCR (Selective Catalytic Reduction)
w
ith a particle filter (FAP) for the treatment of
e
xhaust gases.
Presentation of the SCR system
Using an additive called AdBlue® containing u
rea,
a
catalytic
converter
turns
up to 85%
o
f
nitrous
oxides
(NOx)
into
nitrogen and
w
ater,
which
are
harmless
to
health and the
e
nvironment. The
AdBlue
® additive is held in a special t
ank
located
under the boot at the rear of
t
he
vehicle.
It has a capacity of 17 litres: this
p
rovides
a
driving range of about 12 500 miles
(
20
000
km),
after which an alert is triggered
w
arning
you
when the reserve remaining is
e
nough
for
just 1 500 miles (2 400 km).
During
each
scheduled service of your vehicle
b
y
a
CITROËN dealer or a qualified workshop,
t
he
AdBlue
® additive tank is refilled in order to a
llow
normal operation of the SCR system.
If
the
estimated mileage between two services
i
s
greater
than 12 500 miles (20 000 km), we
r
ecommend
that you go to a CITROËN dealer
o
r
a
qualified workshop to have the necessary
t
op-up
carried out. Once
the AdBlue
® tank is empty, a s
ystem
required
by regulations
p
revents
starting
of the engine.
If the SCR
is faulty, the level of
emissions
from
your vehicle will no
l
onger
meet
the
Euro 6 standard: you
v
ehicle
becomes
polluting.
In
the
event
of
a
confirmed fault
w
ith
the
SCR
system, you must go
t
o
a
CITROËN
dealer or a qualified
w
orkshop
as
soon as possible: after
a
running
distance of 650 miles
(
1 100
km),
a
system will be triggered
a
utomatically
to
prevent engine starting.

Range indicators
When switching on the ignition, an indicator gives an estimate of the distance that can
b
e travelled with your vehicle before engine
s
tarting is automatically prevented, once the
v
ehicle starts using the reserve of AdBlue
® or
after
a
fault
is
detected
with
the
SCR
system.
In
the
event
of
simultaneous
system
fault
and

isplayed. Range greater than 1 500 miles (2 400 km)
When
the ignition is switched on,
n
o information on range is displayed a
utomatically in the instrument panel.
With the type 2 instrument panel, pressing this
b
utton displays the driving range temporarily.
Above
3 000 miles (5 000 km), the value is not

In the event of the risk of non-starting related to a lack of AdBlue®
The engine start prevention system required by regulations is activated
a
utomatically once the AdBlue
