An unlocked service flap may disengage when the vehicle is in motion and block your view or endanger other road users.
If the windscreen wipers are set in motion when the service flap is open, you may be trapped by the wiper linkage.
In smart vehicles, the operating fluid reservoirs are located under the service flap at the front.
Observe all safety regulations when working on the vehicle. Always have work in the engine compartment carried out at a qualified specialist workshop.
Carefully remove snow and dirt from the ventilation slots above the service flap so that air intake is ensured at all times.
The vehicle must be secured against rolling away.
For vehicles with a lockable service flap, this must be unlocked prior to opening it.
Check that the service flap has been closed correctly and there are no small objects (e.g. small stones) in the locking mechanisms.
