176 MAINTAINING YOUR VEHICLE
Drive Belts — Check Condition and Tension
At the mileage shown in the appropriate "Maintenance
Schedule", check the condition of the drive belt for
condition and proper tension. Improper belt tension can
cause belt slippage and failure.
Inspect the drive belt for evidence of cuts, cracks, or
glazing and replace it if there is any sign of damage
which could result in belt failure.

Spark Plugs

Spark plugs must fire properly to assure proper engine
performance and emission control. Install new recom-
mended plugs with the recommended gap at the speci-
fied mileage.
Refer to the "Vehicle Emission Control Information" label
in the engine compartment for spark plug information.

Catalytic Converter

The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
