& WARNING Danger of burns when opening the hood
If you open the 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 hood, allow the engine to cool down.
#
In the event of a fire in the engine compartment, keep the 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 impaired.
#
Avoiding high loads on the engine, drive to the nearest qualified specialist workshop. In doing so, ensure that
#
the coolant temperature display remains below the red marking.
* NOTE Engine damage due to insufficient coolant
Avoid long journeys with insufficient coolant.
