NOTE
To meet government regulations and promote cleaner air,
your vehicle is equipped with an onboard diagnostic sys-
tem (OBD). The engine electronic control module that
controls OBD functions stores various data (especially
about the exhaust emissions). This data will be erased if
the battery cable is disconnected, which could make a
rapid diagnosis difficult. Do not disconnect the battery
cable when the malfunction indicator light (“SERVICE
ENGINE SOON” or “Check engine light”) is on.Spark plugs
N00940900127
Spark plugs must fire properly for good engine performance
and emission-control.
Do not reuse them by cleaning or regapping. Change them at
the mileage listed in the “WARRANTY AND MAINTE-
NANCE MANUAL”.
Your vehicle may be equipped with iridium tipped spark plugs,
which are identified by marks on the ceramic. They do not
require replacement as frequently as the conventional type
spare plug and will last much longer.NOTE
Use the spark plugs listed under “Engine specifications”
on page 9-6 or plugs that are exactly the same. Other
plugs could cause engine damage, performance problems
or radio noise.Fuel hoses
N00941000011
Check the hose surfaces for any heat and mechanical damage,
hard and brittle rubber, cracking, tears, cuts and abrasions. Payspecial attention to the hoses closest to high heat sources such
as the exhaust manifold. Check all the hose connections, such
as clamps and couplings, to make sure they are secure and that
there are no leaks. If you see any wear or damage, replace the
hoses immediately.
Fuel system (tank, pipe line and connection, and
fuel tank filler tube cap)
N00941300144
Check these regularly for damage or leaks in the fuel lines and
connections. Check the fuel tank filler tube cap for damage or
looseness. Pay special attention to the fuel lines closest to high
heat sources such as the exhaust manifold.Evaporative emission control system (except
evaporative emission canister)
N00941400158
If the fuel-vapor vent line is clogged or damaged, the fuel-
vapor mixture will escape, polluting the air.
Have the system checked at an authorized Mitsubishi Motors
dealer at the mileage specified in the “WARRANTY AND
MAINTENANCE MANUAL”.
WA R N I N G
!
If you see a fuel leak or if you smell fuel, do not run
the engine. Any spark (including from the ignition),
flame or smoking material could cause an explosion
or fire. Call an authorized Mitsubishi Motors dealer
or a repair facility of your choice for assistance.
