leaded fuel will extend spark plug life
and reduce maintenance costs.
EAU13445
Catalytic converters This vehicle is equipped with catalytic
converters in the exhaust system.
WARNING
EWA10862
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:

Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.


Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.


Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.


Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
NOTICE
ECA10701
Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.
