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

Use only unleaded gasoline. The use
of leaded gasoline will cause unre-
pairable damage to the catalytic
converter.
