GENERAL INFORMATION 0A-9
Use care not to expose connectors and electrical parts
to water which will be a cause of a trouble.
Always be careful not to handle electrical parts (com-
puter, relay, etc.) in a rough manner or drop them.
PRECAUTIONS FOR CATALYTIC CONVERTER
For vehicles equipped with a catalytic converter, use only unleaded gasoline and be careful not to let a
large amount of unburned 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.)
PRECAUTION FOR INSTALLING MOBILE COMMUNICATION EQUIPMENT
When installing mobile communication equipment such as CB (Citizens-Band)-radio or cellular-tele-
phone, be sure to observe the following precautions.
Failure to follow cautions may adversely affect electronic control system.
Keep the antenna as far away as possible from the vehicle’s electronic control unit.
Keep the antenna feeder more than 20 cm (7.9 in) away from electronic control unit and its wire har-
nesses.
Do not run the antenna feeder parallel with other wire harnesses.
Confirm that the antenna and feeder are correctly adjusted.

PRECAUTIONS
WARNING:
Before attempting service of any type on fuel system, the
followings should be always observed in order to reduce
the risk or fire and personal injury.
Disconnect negative cable at battery.
Do not smoke, and place no smoking signs near work
area.
Be sure to have CO
2 fire extinguisher handy.
Be sure to perform work in a well-ventilated area and
away from any open flames (such as gas hot heater).
Wear safety glasses.
To relieve fuel vapor pressure in fuel tank, remove fuel
filler cap from fuel filler neck and then reinstall it.
As fuel feed line is still under high fuel pressure even
after engine was stopped, loosening or disconnecting
fuel feed line directly may cause dangerous spout of
fuel to occur where loosened or disconnected.
Before loosening or disconnecting fuel feed line, make
sure to relieve fuel pressure “FUEL PRESSURE
RELIEF PROCEDURE” in Section 6.
A small amount of fuel may be released after the fuel
line is disconnected. In order to reduce the chance of
personal injury, cover the fitting to be disconnected
with a shop cloth. Be sure to put that cloth in an
approved container when disconnection is completed.
Note that fuel hose connection varies with each type of
pipe. Be sure to connect and clamp each hose cor-
rectly referring to the figure.
[A] : With short pipe, fit hose as far as it reaches pipe joint as shown.
[B] : With the following type pipe, fit hose as far as its peripheral projection as shown.
[C] : With bent pipe, fit hose as far as its bent part as shown or till depth “b”.
[D] : With straight pipe, fit hose till depth “b”.
[E] : With red marked pipe, fit hose end reaches red mark on pipe.
1. Pipe
2. Hose
3. Clamp
4. Ped mark
“a” : Clamp securely at a position 3 to 7 mm (0.12 – 0.27 in.) from hose end.
