Engine oil level indicator
(Depending on version.)
On versions fitted with an electric oil level
indicator, the state of the engine oil level is
displayed in the instrument panel for a
few
seconds after switching the ignition on, after
the ser vicing information, in the form of
messages. The level read will only be correct if the
vehicle is on level ground and the engine
has been off for more than 30
minutes.
Low oil level
This is indicated by the display of a message
p rompting you to top up, accompanied by the
Service warning lamp and an audible signal.
If the low oil level is confirmed by a
check using
the dipstick, the level must be topped up to
avoid damage to the engine.
For more information on Checking levels ,
refer to the corresponding section.
Oil level indicator fault
This is signalled by the display of the " Oil
level measurement invalid " message in the
instrument panel.
Contact a
CITROËN dealer or a qualified
workshop. In the event of a
fault with the electric
indicator, the oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located under the bonnet.
For more information on Checking levels ,
refer to the corresponding section.
Engine coolant temperature
gauge
With the engine running:
- i n zone A , the temperature is correct,
-

i
n zone B , the temperature is too high; the
associated warning lamp and the central
STOP warning lamp come on in red in the
instrument panel, accompanied by the
display of a


message and an audible signal.

You must stop the vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine.
After switching off the ignition, carefully
open the bonnet and check the coolant
level.
For more information on Checking levels ,
refer to the corresponding section.
AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a
system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
The engine starting prevention system
required by regulations is activated
automatically once the AdBlue
® tank is
empty. It is then no longer possible to
start the engine until the minimum level of
AdBlue
® has been topped up.
Manual display of the range
While the range is greater than 1,500 miles
( 2,400 km), it is not displayed automatically.
F

P
ress this button to temporarily display the
driving range.
Actions required related to a lack
of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reser ve
level corresponding to a range of 1,500 miles
(2, 4 0 0


k m).
Together with the warning lamps, messages
regularly remind you of the need to top up to
avoid engine starting being prevented. Refer to
the Warning and indicator lamps section for
details of the messages displayed.

otherwise indicated.
If a
level drops significantly, have the

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.

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.
