Instruments
Check the engine coolant level regularly.
For more information on Checking
levels, refer to the corresponding section.
AdBlue® fluid ange
indicators
Once the AdBlue® tank is on reserve or after
detection of a fault with the SCR emissions
control system, when the ignition is switched on,
an indicator displays an estimate of the distance
that can be travelled before engine starting is
prevented.
In the event of a simultaneous system fault and
low AdBlue
® level, the shortest-range figure is
the one displayed.
In the event of the risk of non-starting
related to a lack ofAdBlue®
The engine start prevention system
required by regulations is activated
automatically once theAdBlue
® tank is empty.
Range greater than 1,500 miles (2,400 km)
When switching on the ignition, there is no
automatic display of range in the instrument
panel.
Range between 1,500 and 375 miles (2,400
and 600 km)
Once the 1,500 miles (2,400 km)
threshold is reached, this indicator
flashes, accompanied by a temporary message
indicating the driving autonomy expressed in
miles or kilometres before the starting of the
engine is blocked.
Each time the ignition is switched on, the alert
will be accompanied by an audible signal.
The reserve level has been reached; it is
recommended that you top up as soon as
possible.
Range less than 372 miles (600 km)
Once the 372 miles (600 km) threshold is
reached, this indicator flashes,
accompanied by a message indicating the
driving autonomy expressed in miles or
kilometres before the starting of the engine is
blocked.
The alert will be repeated with update of the
remaining range at each increment of 31 miles
(50 km) travelled.
Each time the ignition is switched on, the alert
will be accompanied by an audible signal.
It is imperative to top up as soon as possible
before the tank empties completely. Otherwise
you will not be able to restart the vehicle.
Breakdown related to a lack of AdBlue
®
0 km range reached: the AdBlue® tank is empty.
The regulatory device prevents the engine from
starting.
Unless the AdBlue
® is topped up in the
special additive tank, the vehicle will remain
immobilised.
To be able to restart the engine, you must top up with at least 4 litres of
AdBlue®. You can also call a CITROËN dealer
or a qualified workshop for the top-up
required.
For more information on AdBlue®
(BlueHDi engines) and, in particular
topping up, refer to the corresponding section.
In the event of a fault with the SCR
emissions control system
Detection
The self-diagnostic warning lamp comes
on.
Every time the ignition is switched on, the
emissions fault is confirmed by an audible signal
and a message.
If it is a temporary fault, the alert disappears
as soon as the exhaust emissions return to the
levels required by the standard.
However, if the warning lamp is still on
after 30 miles (50 km) of driving, the fault
is confirmed.
An engine start prevention system will be
activated automatically after 250 miles (400
km) travelled following this confirmation.
See a CITROËN dealer or a qualified
workshop as soon as possible.

Practical information
7Topping up the engine oil level

► Remove the dipstick before topping up.
► Recover the oil filler neck.
► Unscrew the filler cap.
► Install the oil filler neck in the filler hole.
► Top up with oil.
► Remove the oil filler neck from the filler hole.
► Replace the filler cap.
► Replace the dipstick.
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.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.
Power steering fluid
The level of this fluid should be close to the "MAX" mark. Check it, with the
vehicle parked on level ground and with the
engine cold, by reading the level on the filler
neck.
Unscrew the cap secured to the dipstick. To
access the reservoir cap, remove the protective
cover by turning its three fixing screws a quarter
turn, then remove the second cover placed on
the cap.
Engine coolant
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.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.


To gain access to the tank cap, remove the
protective cover by turning its three fixing screws
a quarter of a turn.
In order 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.
Check the coolant level regularly
according to the use of your vehicle
(every 3,000 miles (5,000 km) / 3 months).
