Cleaningt he exhaust pipes
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is arisk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
!Do not clean the exhaust pipe with acid-
based cleaning agents, such as bathroom
cleaner or wheel cleaner.
!Mercedes-AMG vehicles with black exhaust
pipes: the black-chrome tailpipe finishers
should not be polished with achrome polish.
They will otherwise lose their black sheen. For
optimal care, the faceplates should be rubbed with alightly oiled cloth after every car wash.
Commercially available engine and care oils
are suitable for this.
For heavier soiling, you can apply afine paint-
work polish with amicrofiber cloth. Remove
the excess polish residue after polishing.
Impurities combined with the effectsofr oad grit
and corrosive environmental factors may cause
flash rust to form on the surface. You can
restore the original shine of the exhaust pipe by
cleaning it regularly,e specially in winter and
after washing.
XClean the exhaust pipe with acare product
tested and approved by Mercedes-Benz.
