Timing belt 
For proper functioning of the vehicle and  its  emission control systems, the timing belt and  belt tensioner must  be
replaced  every 105,000 miles (168,000 km). Engine damage will occur if the belt fails.
PCV system
(on turbocharged models) 
The nipple in the intake  manifold and  the filter  at the end  of the PCV  hose in the air cleaner  should be  inspected and
cleaned at 105,000 miles (168,000 km) and  thereafter, again at 150,000 mile (240,000 km) intervals.
Spark plugs  
The spark plugs should be  replaced  every 45,000 miles (72,000 km) under normal driving conditions. City driving or
fast  highway  driving may necessitate replacement  sooner.
Under normal driving conditions, spark plugs require no maintenance between replacement  intervals.  When installing
new plugs, be  sure to use the right type and  to tighten them correctly. When changing the plugs, clean the terminals
and  rubber seals.  Also check that the suppressor connectors are in good condition. Cracked or damaged connectors
should be  replaced.
