Coolant

With the engine off and on a level surface, the cold level must be between the 'MIN' A and 'MAX' B marks on the coolant reservoir 1.

Top up the cold level before it reaches the "MIN" mark.

Check your coolant level regularly (the engine may suffer serious damage if coolant is low).

If topping up is required, use only products approved by our Technical Departments, which guarantee:

  • antifreeze protection;
  • corrosion protection for the cooling system.
