down to 40-45°C before carrying out any check.
When carrying out an inspection or maintenance operation inside the engine hood, always open it
completely and make sure that it is kept open by the apposite rod.

q If the engine has just been stopped, before checking the engine oil level wait approximately 15 minutes, in
order to allow the engine to cool down.

"ENGINE COVER (3-84)"
2. Remove the dipstick (G) and wipe it with a cloth.
