Important safety notes

WARNING
If you clean the radiator, the air conditioning
condenser or the protective grid with the
engine at normal operating temperature, you
can burn yourself on the hot components.
There is a risk of injury.
Allow the engine to cool down before cleaning
the radiator, the air conditioning condenser or
the protective grid. Always wear protective
gloves while doing so.
! Only direct the compressed-air, steam or
water jet towards the radiator surface in a
vertical direction. Ensure that the radiator
fins are not damaged. Remove any dirt from
the radiator fins. Damaged or dirty radiator
fins can cause the engine to overheat. If
there is a loss of coolant or damage to the
cooling and heating system, have it
checked at a qualified specialist workshop.
Depending on the nature of the work per-
formed by your vehicle, the engine radiator
and the charge-air cooler may become heavily
soiled.
Check the engine radiator and charge-air
cooler for soiling on the exterior every time
you refuel.
In extremely dirty conditions, e.g. mowing
operations, check the engine radiator several
times a day and clean it whenever necessary.
