Inspect belts for evidence of cuts, cracks, glazing, or
frayed cords and replace if there is indication of damage
that could result in belt failure. Also, check belt routing to
make sure there is no interference between the belts and
other engine components. See your authorized dealer for
service.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emissions control. New plugs should be
installed at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Malfunctioning spark plugs can damage the cata-
lytic converter. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the proper type of spark plug for
use in your vehicle.
Engine Air Cleaner Filter
Refer to the Maintenance Schedule in Section 8 for engine
air cleaner filter maintenance intervals.
NOTE:Be sure to follow the “dusty or off-road condi-
tions” maintenance interval if applicable.
WARNING!
The air induction system (air cleaner, hoses, etc) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc) removed. Failure to do so can result in
serious personal injury.
