Working in the engine compartment
Never attempt to perform any service or repair operations on your vehicle without the necessary professional technical training.
If you are unfamiliar with the statutory guidelines, have any work on the vehicle performed only by a service center.
If work is not carried out properly, there is a danger of subsequent damage and related safety hazards.
Never reach into the engine compartment
Never reach into spaces or gaps in the engine compartment; otherwise, there is a risk of injury, e.g., from rotating or hot parts.
