Practical information -> Electrified vehicles - General recommendations for Your Peugeot 408 4 Door Second Generation (2022-2026)

Practical information  
The vehicle is fitted with a catalytic converter,  
which helps to reduce the level of harmful  
emissions in the exhaust gases.  
Do not inhale the gases emitted by the  
traction battery which are toxic.  
Never work on the high voltage cables  
(purple or orange) or on any other  
high voltage component marked with the  
Electric risk label. Any intervention on  
the high voltage system must be carried  
out by qualified persons in workshops  
qualified and approved to carry out this  
type of work.  
Move away from the vehicle in the event  
of incident or accident, the gases emitted  
being flammable and could cause a fire.  
Exhaust gases contain carbon monoxide  
which is colourless and odourless and yet  
dangerous.  
Traction battery  
Danger of death if inhaled!  
Traction battery overheating  
For petrol engines, you must use unleaded  
fuel.  
The filler neck is narrower, allowing only  
unleaded petrol nozzles to be inserted.  
Never damage, modify or remove the  
high voltage cables (purple or orange) or  
disconnect them from the high voltage  
network.  
If the following warning lamps appear,  
accompanied by the display of a  
message and an audible signal, it is  
required to:  
Never open, modify or remove the cover  
of the traction battery.  
If you have put in the wrong fuel for  
the vehicle, you must have the fuel tank  
drained and filled with the correct fuel  
before starting the engine.  
Never work with cutting and forming  
tools or heat sources near high voltage  
components and cables.  
Stop the vehicle as soon as possible in the  
best conditions of safety.  
In case of low level of fluid in the cooling  
tank, the refilling shall only be performed in  
a qualified and trained workshop to verify that  
the leakage is not in the traction battery.  
Any intervention on the high voltage system  
must be carried out by qualified persons in  
workshops qualified and approved to carry  
out this type of work.  
Damage to the vehicle or the traction battery  
could result in the leakage of toxic gases or  
fluids either immediately or later. PEUGEOT  
recommends that you:  
Switch off the ignition.  
Evacuate the vehicle as quickly as possible  
and move to a safe distance.  
Electrified vehicles  
- General  
recommendations  
These recommendations and general  
Call the fire department and/or the  
emergency services and tell them that the  
vehicle is an electric one.  
information concern electrified vehicles of the  
type: hybrid, rechargeable hybrid and electric.  
Danger of death / Risk of serious injury  
A chain reaction can occur up to a traction  
battery fire.  
High voltage system  
High voltage system voltage is dangerous  
and can cause burns or other injuries or  
even fatal electric shock.  
Since damage to high voltage components is  
not visible, PEUGEOT recommends that you:  
In the event of damage to the traction  
battery  
It is strictly prohibited to work on the vehicle  
yourself.  
Do not touch liquids coming from the battery,  
and in the event of skin contact with these  
products, wash abundantly with water and  
contact a doctor as soon as possible.  
Contact a PEUGEOT dealer or a qualified  
workshop to have the system checked.  
Always inform the fire and emergency  
services in the event of an incident,  
warning that the vehicle is equipped with  
a traction battery.  
Never touch the liquids leaking from the  
traction battery.  
Never touch the components, damaged or  
not, and never let your jewelry or other  
metallic objects come into contact with  
these components.

Practical information  
Disposal of the traction battery  
In the event of a problem  
To preserve the mileage of your vehicle  
and the durability of your traction battery,  
PEUGEOT recommends that you:  
The traction battery is designed for the life of the  
vehicle if the recommendations of PEUGEOT  
are followed.  
If it becomes necessary to replace the battery,  
contact the PEUGEOT dealer for instructions on  
its disposal. Improper disposal carries the risk of  
severe burns, electric shock, and damage to the  
environment.  
In accordance with regulations, PEUGEOT  
ensures a second life or recycling of this  
component in collaboration with qualified  
operators.

All work on or modifications to the  
vehicle’s electrical system (including the  
traction battery, connectors, purple cables  
and other components visible from the interior  
or exterior) is strictly prohibited - risk of  
severe burns or potentially fatal electric shock  
(short-circuit/electrocution)!  
Do not expose the vehicle to temperatures  
below -30°C and above +60°C for more  
than 24 hours.  
Do not use a generator to recharge your  
vehicle's traction battery.  
Contact a PEUGEOT dealer or a qualified  
workshop.  
Vehicle in storage for more than 1  
month  
High-pressure washing  
To avoid damaging the electrical  
components, it is expressly prohibited to  
use high-pressure washing in the engine  
compartment or under the body.  
Do not use a pressure greater than 80 bar  
when washing the bodywork.  
Always park the vehicle in a place with  
temperatures between -10°C and +30°C  
(parking in a place with extreme temperatures  
can damage the traction battery).  
Carry out the charging procedure for the  
traction battery (48V) via the accessory  
battery (12V) and the DC/DC converter.  
Refer to the 12 V battery/Accessory  
batteries section for the charging the  
batteries using a battery charger procedure.  
Hybrid system  
For more information, refer to  
the General recommendations on  
electrified vehicles.  
Traction battery  
Electrical system  
The 48 V Li-ion (Lithium-ion) traction battery  
stores the electrical energy needed to propel the  
vehicle.  
The traction battery is automatically charged to  
ensure that the charge level is always around  
50% of the maximum level, in order to fully  
exploit the hybrid functionality and, at the same  
time, always have some capacity available for  
the energy recovery operation.  
It is located under the front left seat.  
The traction battery's range varies depending on  
the type of driving, the route and the ageing of its  
components.  
The electrical circuit of the hybrid system is  
identified by purple cables and its components  
are marked with this symbol:  
Rechargeable hybrid or  
electric vehicles - Specific  
recommendations  
These recommendations and specific  
information are only applicable to rechargeable  
hybrid and electric vehicles.  
The hybrid powertrain uses a voltage of 48  
V. This system may be hot both when the  
ignition is on and after switching it off.  
Comply with the warning messages shown on  
the labels.  
They introduce the control unit (mode 2) required  
to carry out the standard charging at home.  
The traction battery ageing depends on  
several factors, such as climatic conditions  
and the distance travelled.
