Emission-control system maintenance
9-20 Vehicle care and maintenance
9
To be sure the emission-control system works
properly, have your vehicle inspected and
maintained by a certified Mitsubishi EV
dealer. This should be done at the time or
mileage specified in the “WARRANTY AND
MAINTENANCE MANUAL”.
These, and all the other “general” mainte-
nance services listed in this manual, need to
be performed to keep your vehicle running
properly and reliably.
You should also have an inspection and ser-
vice any time you suspect a malfunction.

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”.
N00941000040
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.
N00950101060
Have the valve clearance checked at a certi-
fied Mitsubishi EV dealer at the mileage
specified in the “WARRANTY AND MAIN-
TENANCE MANUAL”.
If the engine sounds abnormally loud, have
adjustments made by a certified Mitsubishi
EV dealer.

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
high heat sources such as the exhaust mani-
fold.
NOTE
 To meet government regulations and pro-
mote cleaner air, your vehicle is equipped
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
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
Intake valve clearance
Fuel system (tank, pipe line and
connection, and fuel tank filler
cap)
WARNING
 If you see a fuel leak or if you smell fuel,
do not start the Plug-in Hybrid EV sys-
tem. Any spark (including from the igni-
tion), flame or smoking material could
cause an explosion or fire. Call a certified
Mitsubishi EV dealer for assistance.
