WARNING
Stop! Before working in the engine compart­
ment, always read and heed all WARNINGS
3.2 "Working in the engine com ­
partment. " The engine compartment of any
motor vehicle is a pot entially dangerou s area
and can cause serious personal injury.
WARNING
Hot steam or coo lant can cause serious burns.
• Never open the engine hood if you sec
steam or coo lant escapi ng from the engine
compartment. Always wa it until you no longer
sec or hea r steam or coo lant escap ing from the
engi ne.
• Always let the en gi ne to cool down com­
pletely before carefully open ing the engine

WARNING (continued)
Apply the parking brake firmly and put
the selector in P (Park, automatic trans­
mis sion) or Neutral (manual transmis­
s ion) .
Keep c hildren a nd oth ers away from the

den ly - even when the engine has been
switched
for a longer period of tim e and the
