Practical information -> Checking levels for Your Peugeot 408 4 Door Second Generation (2022-2026)

Practical information  
Checking using the dipstick  
9.  
Engine oil dipstick  
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).  
For the location of the dipstick, please refer  
to the illustration of the corresponding engine  
compartment.

Electric engine  
Grasp the dipstick by its coloured grip and  
pull it out completely.  
Used products  
Wipe the end of the dipstick using a clean,  
lint-free cloth.  
Avoid prolonged contact of used oil or  
fluids with the skin.  
Most of these fluids are harmful to health and  
very corrosive.  
1. Screenwash fluid reservoir  
2. Engine coolant reservoir (level only)  
3. Brake fluid reservoir  
4. Battery/Fuses  
5. Remote earth point (-)  
Do not discard used oil or fluids into  
sewers or onto the ground.  
6. Fusebox  
7. 400 V electrical circuit  
8. Emergency circuit-breaker for emergency  
services and maintenance technicians  
Empty used oil into the containers reserved  
for this purpose at a PEUGEOT dealer or a  
qualified workshop.  
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).  
For more information on the Charging system  
(Electric), refer to the corresponding section.  
After topping up, carefully screw the cap back  
on to the filler neck  
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  
Do not start the engine if the level is:  
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.  
above mark A: contact a PEUGEOT dealer  
or a qualified workshop.  
below mark B: top up the engine oil  
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).  
immediately.  
Oil grade  
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 PEUGEOT dealer or qualified  
workshop).  
The fluids must comply with the  
Manufacturer's requirements and with the  
vehicle's engine.  
In order to maintain the reliability of the  
engine and emissions control system,  
never use additives in the engine oil.  
Use of non-recommended oil may invalidate  
your warranty in the event of engine failure.

Practical information  
Topping up the engine oil level  
For the location of the engine oil filler cap,  
please refer to the corresponding engine  
compartment illustration.  
In winter (temperatures below zero), a fluid  
containing an anti-freeze agent which is  
appropriate for the temperature conditions must  
be used in order to protect the system's  
components (pump, tank, ducts, jets).  
Clean the cap before removing it to  
refill.Use only DOT4 brake fluid from a  
sealed container.  
Never remove the oil filler cap with  
the engine running. Risk of burns and  
splashes inside the engine compartment.  
Engine coolant  
Filling with pure water is prohibited in all  
circumstances (risk of freezing, limescale,  
etc.).  
It is normal to top up this fluid  
between two services.  
Add oil in small quantities, avoiding any spills  
on engine components (risk of fire).  
The check and top-up must only be done with  
the engine cold.  
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.  
Checks  
Unless otherwise indicated, check these  
components in accordance with the  
Manufacturer's service schedule and according  
to your engine.  
Wait a few minutes before checking the level  
again using the dipstick.  
Top up the level if necessary.  
After checking the level, carefully screw the  
oil filler cap back on and push the dipstick  
back into its tube up to the stop.  
Otherwise, have them checked by a PEUGEOT  
dealer or a qualified workshop.  
If the level is close to or below the "MIN" mark, it  
is essential to top it up.  
The dipstick must be pushed completely in  
to prevent oil from spilling onto the engine.  
Risk of fire inside the engine compartment.  
When the engine is hot, the temperature of the  
coolant 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.  
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.  
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.  
Once the pressure has dropped, remove the cap  
and top up to the required level.  
12 V battery  
Brake fluid  
The battery does not require any  
maintenance.  
The level of this fluid should be close  
to the "MAX" mark. If not, check the  
brake pads for wear.  
Screenwash fluid  
Top up to the required level when  
necessary.  
Check regularly that the terminals are  
correctly tightened (versions without quick-  
release terminals) and that the connections are  
clean.  
To know how often the brake fluid should be  
replaced, refer to the manufacturer's servicing  
schedule.  
Fluid specification  
The fluid must be topped up with a pre-mixed  
product.
