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. 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 service 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.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emissions control device.

Fuel System
The Electronic Fuel Injection high-pressure fuel system’s
hoses and fittings have unique material characteristics
that provide adequate sealing and resist attack by dete-
riorated gasoline.
You are urged to use only the manufacturer’s specified
hoses and fittings, or their equivalent in material and
specification, in any fuel system servicing. It is manda-
tory to replace any damaged hoses or fittings that have
been removed during service. Care should be taken with
installing fittings to ensure they are properly installed
and fully connected. See your authorized dealer for
service.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the “Mainte-
nance Schedule” in Section 8.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering Hoses
When servicing the vehicle for scheduled maintenance,
inspect the surface of the hoses and nylon tubing for
evidence of heat and mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling suggest deterioration of the rubber. Particu-
lar attention should be made to examining those hose
surfaces nearest to high heat sources, such as the exhaust
manifold.
