To the specified intervals in the "scheduled maintenance chart" (sect. 4 - 2) Check the coolant level contained in the expansion reservoir, on the right side of the vehicle.
The coolant level must be between the max. And min marks on the tank.
If the level is low, top up with the recommended coolant.
Remove the filler cap (1) and top up with new coolant to the specified level.
Refit the plug (1).

For optimal operating conditions (coolant mixture starting to freeze at -20 C), the recommended fluid antifreeze should be mixed with water in the following percentages: antifreeze: 35 to 40% of the volume; water: 65 to 60% of the volume.
Important
Very hard water with a high mineral salt content can damage the engine.
Increase the amount of antifreeze to up to 55% volume in the case of very cold climates.
Important
Solutions with less than 30% of antifreeze will not provide sufficient protection against corrosion.
