328 MAINTAINING YOUR VEHICLE
To minimize the possibility of catalyst damage:
• Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected for a prolonged period.

Crankcase Emission Control System

Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. Do not attempt to clean the
old PCV valve.
Check the ventilation hose for indication of damage or
plugging deposits. Replace if necessary.

Fuel Filter

A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent fuel filter replacement may be necessary. The
fuel filters are located inside the fuel tank. See your
authorized dealer for service.
