The exhaust system contains catalytic
converter(s) to reduce harmful exhaust
emissions.
WARNING
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
doing any maintenance work.
 Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.
