Do not attempt to top up the fuel tank after the fuel pump nozzle
shuts off automatically. Continued refueling may cause fuel
overflow, resulting in fuel spray and possibly a fire.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do
not carelessly disconnect the harness connectors which are
related to the engine control system and TCM (Transmission
Control Module) system. The connectors should be discon-
nected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.

PRECAUTIONS FOR MULTIPORT FUEL INJECTION
SYSTEM OR ENGINE CONTROL SYSTEM
NLGI0001S04+Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to“OFF”position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
+Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
+Be careful not to jar components such as ECM and mass air
flow sensor.
PRECAUTIONS FOR THREE WAY CATALYSTNLGI0001S05If a large amount of unburned fuel flows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
+When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
+Do not run engine when the fuel tank level is low, otherwise the
engine may misfire, causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.

PRECAUTIONS FOR HOSESNLGI0001S06Hose Removal and InstallationNLGI0001S0601+To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
