& WARNING Risk of burns from hot com‐
ponent parts in the engine compartment
Certain component parts in the engine com‐
partment can be very hot, e.g. the engine, the
cooler and parts of the exhaust system.
Allow the engine to cool down and only
#
touch component parts described in the
following.
The engine oil becomes dirty during operation,
loses quality and also gradually loses volume.
Check the oil level regularly and top up the oil or
have it changed if necessary.
Regularly check the fluid level and the major
assemblies for leaks. If you detect fluid loss, for
example, oil drops on the vehicle parking space,
consult a qualified specialist workshop as quickly
as possible.
Only check the oil level when the engine is at
#
normal operating temperature.
