GENERAL INFORMATION 0A-9
When disconnecting vacuum hoses, attach a tag describing
the correct installation positions so that the hoses can be re-
installed correctly.
After servicing fuel, oil, coolant, vacuum, exhaust or brake
systems, check all lines related to the system for leaks.
For vehicles equipped with fuel injection systems, never dis-
connect the fuel line between the fuel pump and injector
without first releasing the fuel pressure, or fuel can be
sprayed out under pressure.
PRECAUTIONS FOR CATALYTIC CONVERTER
For vehicles equipped with a catalytic converter, use only un-
leaded gasoline and be careful not to let a large amount of un-
burned gasoline enter the converter or it can be damaged.
± Conduct a spark jump test only when necessary, make it as
short as possible, and do not open the throttle.
± Conduct engine compression checks within the shortest
possible time.
± Avoid situations which can result in engine misfire (e.g.
starting the engine when the fuel tank is nearly empty).
