Levels

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.
Level check frequency
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.
Before working in the engine compartment, be sure to switch off the ignition by pressing the engine stop button (refer to the 'Starting and stopping the engine' section in chapter 2).
Replacement frequency
Refer to your vehicle's maintenance document.

No work must be carried out on the cooling system while the engine is hot.
Risk of burns.
If the level drops abnormally or repeatedly, consult a brand representative.
Brake fluid
Check the level with the engine off and on a level surface. Check it often and, in any case, whenever you notice even a slight change in braking efficiency.
Level 2
The level drops normally as the pads wear, but it must never fall below the 'MIN' warning mark.
If you wish to check the wear of the brake discs and drums yourself, obtain the document describing the inspection method, available from the brand's network or on the manufacturer's website.
When working near the engine, it may be hot. In addition, the cooling fan may start at any time.
Risk of injury.
Filling
Any work on the hydraulic circuit must be followed by a fluid replacement carried out by a specialist.
You must use a fluid approved by our Technical Departments (taken from a sealed container).
Replacement frequency
Refer to your vehicle's maintenance document.
