Checking levels
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.
Checking using the dipstick
A = MA X
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.
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).
To ensure that the reading is correct,
your vehicle must be parked on a level
sur face with the engine having been off
for more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms). B = MINIf you find that the level is above the A mark or
below the B mark, do not star t the engine
.
-
I
f the level is above the MAX
mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.

indicator in the instrument panel is not valid
during the 30 minutes after topping up.
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
and emission control system, never use
additives in the engine oil.

Checks
146
Coolant level
The coolant level should be close
to the "MA X" mark but should never
exceed it.
Fluid specification
For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.
In wintry conditions, it is recommended that you
use an ethyl alcohol or methanol based fluid.
Coolant specification
The coolant must conform to the
manufacturer's recommendations.
Screenwash fluid level
When the engine is warm, the temperature of
the coolant is regulated by the fan.Top up the level when necessary.
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.
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 any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop. When
the pressure has dropped, remove the cap and
top up the level.
Diesel additive level (Diesel
engine with particle filter) Used products
To p p i n g u p
This additive must be topped up by a CITROËN
dealer or a qualified workshop without delay. Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.
The additive reservoir low
level is indicated by fixed
illumination of this warning lamp,
accompanied by an audible
warning and a message in the
multifunction screen.
Checks
147
Particle filter (Diesel)
The start of saturation of the
particle filter is indicated by
the temporary illumination of this warning lamp
accompanied by a message in the multifunction
screen.
As soon as the traffic conditions permit, regenerate
the filter by driving at a speed of at least 40 mph
(60 km/h) until the warning lamp goes off.
If the warning lamp stays on, this indicates a low
additive level.
For more information on checking levels, refer to
the corresponding section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
Checks
12 V battery
The battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.
Air filter and passenger compartment filter
Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Oil filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
When carrying out work on the battery, refer
to the "12 V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g.
city driving), replace them twice as often
if necessary .
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.

In the event of a fault with the SCR emissions control system
A system that prevents engine starting is activated automatically from 650 miles (1 100 km) after confirmation of a fault with the SCR emissions control
system. Have the system checked by a CITROËN dealer or a qualified workshop as soon as possible.You have exceeded the authorised
driving limit: the starting prevention
system inhibits engine starting.
If it is a temporary fault, the alert
disappears during the next journey,
after self-diagnosis of the SCR system.
The UREA, SERVICE and diagnostic warning
lamps comes on, accompanied by an audible
signal and the display of the message
"Emissions fault".
The alert is triggered when driving when the
fault is detected for the first time, then when
switching on the ignition for subsequent
journeys, while the fault persists. In the event of the detection
of a fault
If a fault with the SCR system is confirmed (after
30
miles (50 km) covered with the permanent display
of the message signalling a fault), the SERVICE and
engine diagnostic warning lamps come on and the
UREA warning lamp flashes, accompanied by an
audible signal and the display of a message (e.g.:
"Emissions fault: Starting prevented in 150 miles")
indicating the remaining range express in miles or
kilometres.
While driving, the message is displayed every
30
seconds while the fault with the SCR system
persists.
The alert is repeated when switching on the ignition.
You should go to a CITROËN dealer or a qualified
workshop as soon as possible.
Other wise, you will not be able to restart your engine.
