Checking levels
Take care when working under the bonnet, as certain areas of the engine
m
ay be extremely hot (risk of burns)
a
nd the cooling fan could start at any
t
ime (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 so equipped, or
u
sing the dipstick.
Checking using the dipstick
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
I f a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
If you find that the level is above the A
mark or
belo
w the B mark, do not star t the engine.
-
I
f the level is above the MAX
mark (risk
o
f damage to the engine), contact a
C
ITROËN dealer or a qualified workshop.
-
I
f the level is below the MIN
mark, you
m
ust top up the engine oil.
A = MA X
B = MIN
To
ensure that the reading is correct,
y
our vehicle must be parked on a level
s
ur face with the engine having been off
f
or more than 30 minutes.
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).The
location of the dipstick is shown in the
c
orresponding underbonnet layout view.
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 .
Oil grade
Before topping-up the oil or changing the oil, c
heck that the oil is the correct grade for your
e
ngine and conforms to the manufacturer's
r
ecommendations.

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
a
nd emission control system, never use
a
dditives in the engine oil. The
brake fluid level should be close t
o the "MA X" mark. If it is not, check t
he brake pad wear.
Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule f
or details of the interval for this operation.
Fluid specification

Coolant level
The coolant level should be close
to the "MA X" mark but should never
e
xceed it.
In
addition, as the cooling system is pressurised,

at
least one hour after switching off the
e
ngine
before carrying out any work.
To
avoid
any risk of scalding, unscrew the cap by
t
wo
turns
to allow the pressure to drop. When the
p
ressure
has dropped, remove the cap and top
u
p
the
level.
Changing the coolant
The coolant does not have to be replaced at routine services.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades. When the engine is warm, the temperature of
t
he coolant is regulated by the fan.
Fluid specification
The coolant must conform to the ma
nufacturer's r ecommendations.

Checks
12 V battery
The battery does not require any maintenance.
H owever, check regularly that the terminals
a
re correctly tightened (versions without quick
r
elease terminals) and that the connections
a
re clean.Refer to the manufacturer's service schedule for details of the
replacement
intervals for these
c
omponents.
Air filter and passenger compartment filter
Replace the oil filter each time the e ngine oil is changed.
Refer
to the manufacturer's
s
ervice schedule for details of
the
replacement interval for this
c
omponent.
Oil filter
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
O ther wise, have them checked by a CITROËN dealer or a qualified workshop.
Depending
on the environment (e.g. dusty
a
tmosphere) and the use of the vehicle
(e.g.
city driving), replace them twice as often
if necessary .
A
clogged passenger compartment filter may
h
ave an adverse effect on the per formance
o
f the air conditioning system and generate
u
ndesirable
o
dours.
Particle filter (Diesel)
The start of saturation of the
particle filter is indicated by the
fixed illumination of this warning
l
amp accompanied by a warning
m
essage.
As
soon
as
the traffic conditions permit,
r
egenerate
the filter by driving at a speed of at
l
east
40
mph (60 km/h) until the warning lamp
g
oes
off.
If
the
warning lamp stays on, this indicates a

Refer
to
the "Diesel additive level" section.
