Checking using the dipstick  
10. Priming pump*  
For the location of the dipstick, please refer  
to the illustration of the corresponding engine  
compartment.  
11. Degassing screw*  
Avoid prolonged contact of used oil or  
fluids with the skin.  
Diesel fuel system  
Most of these fluids are harmful to health and  
very corrosive.  
►ꢀ Grasp the dipstick by its coloured grip and pull  
it out completely.  
This system is under very high pressure.  
All work must be carried out only by a dealer or  
a qualified workshop.  
►ꢀ Wipe the end of the dipstick using a clean, lint-  
free cloth.  
Do not discard used oil or fluids into  
sewers or onto the ground.  
Empty used oil into the containers reserved  
for this purpose at a dealer or a qualified  
workshop.  
Checking levels  
Check all of the following levels regularly in  
accordance with the manufacturer's service  
schedule. Top them up if required, unless  
otherwise indicated.  
Engine oil  
The level is checked, with the engine  
having been switched off for at least 30  
minutes and on level ground, either using the oil  
level indicator in the instrument panel when the  
ignition is switched on (for vehicles equipped with  
an electric gauge), or using the dipstick.  
It is normal to top up the oil level between two  
services (or oil changes). It is recommended that  
you check the level, and top up if necessary, every  
3,000 miles (5,000 km).  
►ꢀ Reinsert the dipstick and push fully down,  
then pull it out again to visually check the oil level:  
the correct level is between marks A (max) and  
B (min).  
If a level drops significantly, have the  
corresponding system checked by a dealer or a  
qualified workshop.  
The fluids must comply with the  
manufacturer's requirements and with  
the vehicle's engine.  
Do not start the engine if the level is:  
– above mark A: contact a dealer or a qualified  
workshop.  
– below mark B: top up the engine oil  
immediately.  
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).  
Oil grade  
In order to maintain the reliability of the  
engine and emissions control system,  
never use additives in the engine oil.  
Before topping up or changing the engine  
oil, check that the oil is suitable for your engine  
and complies with the recommendations in  
the service schedule supplied with the vehicle  
(or available from your dealer or qualified  
workshop).

Use of non-recommended oil may invalidate  
your warranty in the event of engine failure.  
appropriate for the temperature conditions  
Engine coolant  
must be used in order to protect the system's  
components (pump, tank, ducts, jets).  
It is normal to top up this fluid between  
two services.  
The check and top-up must only be done with the  
engine cold.  
Topping up the engine oil level  
Filling with pure water is prohibited in all  
circumstances (risk of freezing, limescale,  
etc.).  
For the location of the engine oil filler cap, please  
refer to the corresponding engine compartment  
illustration.  
A level of coolant that is too low risks causing  
major damage to the engine; the coolant level  
must be close to the "MAX" mark without ever  
going above it.  
►ꢀ Add oil in small quantities, avoiding any spills  
on engine components (risk of fire).  
►ꢀ Wait a few minutes before checking the level  
again using the dipstick.  
Diesel fuel additive (Diesel with  
particle filter)  
On reaching the minimum level in the  
particle filter additive tank, this warning  
lamp comes on fixed, accompanied by an audible  
signal and a warning message.  
If the level is close to or below the "MIN" mark, it  
is essential to top it up.  
When the engine is hot, the temperature of the  
coolant is regulated by the fan.  
►ꢀ Top up the level if necessary.  
►ꢀ After checking the level, carefully screw the  
oil filler cap back on and replace the dipstick in  
its tube.  
As the cooling system is pressurised, wait at least  
one hour after switching off the engine before  
carrying out any work.  
Topping up  
The oil level indication displayed on the  
instrument panel when the ignition is  
switched on is not valid for 30 minutes  
following an addition of oil.  
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.  
The topping up of this additive must be carried  
out quickly.  
Visit a dealer or a qualified workshop.  
AdBlue® (BlueHDi)  
An alert is triggered when the reserve level is  
Once the pressure has dropped, remove the cap  
and top up to the required level.  
Brake fluid  
The level of this fluid should be close to the  
"MAX" mark. If not, check the brake pads  
for wear.  
reached.  
Screenwash fluid  
For more information on the Indicators and in  
particular the AdBlue range indicators, refer to  
the corresponding section.  
Top up to the required level when  
necessary.  
To know how often the brake fluid should be  
replaced, refer to the manufacturer's servicing  
schedule.  
To avoid the vehicle being immobilised in  
accordance with regulations, you must top up the  
AdBlue tank.  
For more information on AdBlue® (BlueHDi), and  
in particular the supply of AdBlue, refer to the  
corresponding section.  
Fluid specification  
The fluid must be topped up with a pre-mixed  
product.  
Clean the cap before removing it to refill.  
Use only DOT4 brake fluid from a sealed  
container.
