9-24 Vehicle care and maintenance
NOTE
 To meet government regulations and pro-
mote cleaner air, your vehicle is equipped
N00940800328
with an onboard diagnostic system (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 engine malfunction
indicator ("SERVICE ENGINE SOON" or
"Check engine light") is ON.
Spark plugs
Spark plugs must fire properly to ensure
proper engine performance and emission-
control.
Do not reuse spark plugs by cleaning or
regapping. Spark plugs should be replaced at
the mileage specified in the "WARRANTY
AND MAINTENANCE MANUAL".
NOTE
 Use the recommended or equivalent spark
plugs listed under "Engine specifications" on
page 11-6. Use of other plugs could cause
engine damage, loss of performance or radio
noise.
Fuel hoses
Check the hose surfaces for any heat and
mechanical damage, hard and brittle rubber,
cracking, tears, cuts and abrasions. Pay spe-
cial 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.
Intake valve clearance
Have the valve clearance checked at an
N00940900231
authorized Mitsubishi Motors dealer at the
mileage specified in the "WARRANTY AND
MAINTENANCE MANUAL".
If the engine sounds abnormally loud, have
adjustments made
Mitsubishi Motors dealer.
Fuel system (tank, pipe line and
connection, and fuel tank filler
cap)
Check these regularly for damage or leaks in
the fuel lines and connections. Check the fuel
tank filler cap for damage or looseness. Pay
special attention to the fuel lines closest to
N00941000040
N00950100050
