Practical information  
Diesel engine  
Electric motor  
The fluids must comply with the  
manufacturer's requirements and with  
the vehicle's engine.  
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).

Used products  
Avoid prolonged contact of used oil or  
fluids with the skin.  
Most of these fluids are harmful to health and  
very corrosive.

10. Priming pump*  
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 PEUGEOT dealer or a  
qualified workshop.  
For more information on the Charging system  
(Electric), refer to the corresponding section.  
The Diesel fuel system operates under  
very high pressure.  
All work on this circuit must be carried out  
only by a PEUGEOT 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.  
If a level drops significantly, have the  
corresponding system checked by a PEUGEOT  
dealer or a qualified workshop.  
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

Practical information  
To know how often the brake fluid should be  
replaced, refer to the manufacturer's servicing  
schedule.  
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).  
– above mark A: contact a PEUGEOT dealer or  
a qualified workshop.  
– below mark B: top up the engine oil  
immediately.

Clean the cap before removing it to refill.  
Use only DOT4 brake fluid from a sealed  
container.  
Oil grade  
Before topping up the oil or changing  
the oil, check that the oil is the correct  
grade for your engine and conforms to the  
manufacturer's recommendations.  
In order to maintain the reliability of the  
engine and emissions control system,  
never use additives in the engine oil.  
Engine coolant  
It is normal to top up this fluid between  
two services.  
Checking using the dipstick  
Topping up the engine oil level  
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.  
For the location of the dipstick, please refer  
to the illustration of the corresponding engine  
compartment.  
For the location of the engine oil filler cap, please  
refer to the corresponding under-bonnet engine  
compartment illustration.  
Take the dipstick by its coloured grip and pull  
it out completely.  
► Wipe the end of the dipstick using a clean,  
non-fluffy cloth.  
► 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.  
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.  
► Refit the dipstick and push fully down, then  
pull it out again to make the visual check: the  
correct level is between marks A and B.  
Top up the level if necessary.  
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.  
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.  
► After checking the level, carefully screw the  
oil filler cap back on and replace the dipstick in  
its tube.  
Within 30 minutes of adding oil, the oil  
level indication 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.  
Once the pressure has dropped, remove the cap  
and top up to the required level.  
A = MAX  
B = MIN  
Do not start the engine if the level is:

Practical information  
Versions equipped with Stop & Start are  
fitted with a 12 V lead-acid battery of  
specific technology and specification.  
Its replacement should be carried out only by  
a PEUGEOT dealer or a qualified workshop.  
Screenwash fluid  
Checks  
Unless otherwise indicated, check these  
components in accordance with the  
manufacturer's service schedule and according  
to your engine.  
Top up to the required level when  
necessary.  
Fluid specification  
The fluid must be topped up with a ready-to-use  
mixture.  
In winter (temperatures below zero), a liquid  
containing an agent to prevent freezing must  
be used which is appropriate for the prevailing  
conditions, in order to protect the elements of the  
system (pump, tank, ducts, jets, etc.).  
Otherwise, have them checked by a PEUGEOT  
dealer or a qualified workshop.  
Passenger compartment  
filter  
Depending on the environment and the  
use of the vehicle (e.g. dusty atmosphere,  
city driving), change it twice as often, if  
necessary.  
Only use products recommended by  
PEUGEOT or products of equivalent  
quality and specification.  
In order to optimise the operation of  
components as important as those in the  
braking system, PEUGEOT selects and offers  
very specific products.  
Filling with pure water is prohibited under  
all circumstances (risk of freezing,  
limestone deposits, etc.).  
A clogged passenger compartment filter  
can adversely affect air conditioning  
system performance and generate  
undesirable odours.  
12 V battery  
AdBlue (BlueHDi)  
An alert is triggered when the reserve level is  
reached.  
For more information on Indicators and in  
particular the AdBlue range indicators, refer to  
the corresponding section.  
To avoid the vehicle being immobilised in  
accordance with regulations, you must top up the  
AdBlue tank.  
The battery does not require any  
maintenance.  
Air filter  
However, check regularly that the terminals  
are correctly tightened (versions without quick  
release terminals) and that the connections are  
clean.  
Depending on the environment and the  
use of the vehicle (e.g. dusty atmosphere,  
city driving), change it twice as often, if  
necessary.  
For more information on the precautions  
to take before any work on the 12 V  
battery, refer to the corresponding section.  
Oil filter  
For more information on AdBlue® (BlueHDi),  
and in particular on the supply of AdBlue, refer to  
the corresponding section.  
Change the oil filter each time the engine  
oil is changed.  
Particle filter (Diesel)  
When the particle filter is  
approaching saturation, this
