Coolant level

Combustion version

With the ignition switched off and on level ground, the levels when cold must be between the "MINI" and "MAXI" marks on the two coolant reservoirs:
  • reservoir 2 is used for the high-temperature engine cooling system;
  • reservoir 3 is used for the low-temperature engine cooling system.
Top up this level when cold, before it reaches the "MINI" mark.
Tip
When filling, fill the reservoirs slightly above the "MAXI" level (approximately 10 mm).

Frequency of checking coolant level

Check the coolant level regularly (very severe damage is likely to be caused to the engine if it runs out of coolant).
If the level needs to be topped up, only use products approved by our Technical Department which ensure:
  • antifreeze protection;
  • anti-corrosion protection of the cooling system.

Replacement intervals

Refer to the maintenance document for your vehicle.
Tip
If there is an abnormal or repeated drop in the fluid levels, contact an approved dealer.
WARNING
No operations should be carried out on the cooling circuit when the engine is hot.
Risk of burns.

Electric version

The level should be read with the engine switched off and on level ground. For each reservoir, the level when cold must be between the "MINI" and "MAXI" mark on the coolant reservoirs:
  • reservoir 1 is used to cool the engine;
  • reservoir 2 is used for the heating circuit.
  • reservoir 3 is used to cool the engine and the traction battery;
Top up these levels when cold before they reach the "MINI" mark.
Depending on the vehicle, the location of the coolant reservoirs may vary.
Note: for a new vehicle in the running in phase: the fluid level may be higher than the "MAXI" mark on the reservoir, then drop between the level "MINI" and "MAXI". This does not present a risk.
Tip
If there is an abnormal or repeated drop in one of the three fluid levels, contact an approved dealer.
WARNING
No work should be carried out on the cooling circuits when the engine is hot.
Risk of burns.
WARNING
The vehicle drive system in an electric vehicle uses a direct voltage of approximately 400 volts.
This system can get hot during and after switching off the ignition.
Respect warning messages given on the labels in the vehicle.
Any intervention or modification on the vehicle's 400 V electrical system (components, cables, connectors, traction battery) is strictly prohibited.
The risk of serious burns or electric shocks can lead to death.
The engine cooling fan may also start at any moment. The label in the engine compartment reminds you of this.
Risk of injury.

Frequency of checking coolant level

Check the coolant levels regularly (very severe damage is likely to be caused to the engine and battery if there is insufficient coolant).
If the level needs to be topped up, only use products approved by our Technical Department which ensure:
  • antifreeze protection;
  • anti-corrosion protection of the cooling system.

Replacement intervals

Refer to the maintenance document for your vehicle.
WARNING
Do not do any work under the bonnet when the vehicle is charging or when the ignition is switched on.
WARNING
When working in the engine compartment, ensure that the windscreen wiper stalk is in the park position.
Risk of injury.
