converter, extremely high temperatures
are generated in this vehicle. Do not remove the
heat shields installed adjacent to various sec-
tions of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle and while parking, take care to avoid pos-
sible contact between the hot exhaust system
and any highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead to a
fire, and with it the risk of serious property dam-
age as well as personal injury.
