WARNING Danger of burns when opening the engine hood
If you open the engine hood when the engine has overheated or during a fire in the engine compartment, you
could come into contact with hot gases or other escaping operating fluids.
#
Before opening the engine hood, allow the engine to cool down.
#
In the event of a fire in the engine compartment, keep the engine hood closed and call the fire service.
#
Wait until the engine has cooled down.
#
Make sure that the air supply to the radiator is not obstructed.
#
Avoiding high loads on the engine, drive on to the nearest qualified specialist workshop. When doing so, ensure
that the coolant temperature display remains below 248 °F (120 °C).
