NOTE
If the fuel tank filler pipe cap is not tight while driving,
the engine malfunction indicator (“SERVICE ENGINE
SOON” or “Check engine light”) may come on when the
onboard diagnostic (OBD) system performs a self check.
Always tighten the fuel tank filler pipe cap until you hear
clicking sounds.
The indicator will go off after driving several times. If the
indicator does not go off, contact your authorized Mitsub-
ishi Motors dealer or a repair facility of your choice as
soon as possible.

Engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”)
N00520500468
This indicator is a part of the onboard diagnostic (OBD) sys-
tem which monitors the emissions, engine, and automatic tran-
saxle control systems. If a problem is detected in one of these
systems, this indicator comes on. When the ignition key is
turned to the “ON” position, this indicator normally comes on
and goes off a few seconds later.
This indicator will come on if the fuel tank filler cap is not
properly tightened. If the indicator comes on and stays on after
refueling, stop the engine and check that the cap is properly
tightened. (Turn the cap clockwise until you hear clicking
sounds.)
If this indicator does not go off after several seconds or lights
up while driving, have the system checked as soon as possible
at an authorized Mitsubishi Motors dealer or a repair facility of
your choice.
NOTE
Do not disconnect the battery cable when the Engine mal-
function indicator (“SERVICE ENGINE SOON” or
“Check engine light”) is on.
The engine electronic control module stores critical OBD
information (especially exhaust emission data), which
may be lost if the battery cable is disconnected while the
engine malfunction indicator is on. This will make it diffi-
cult to diagnose the cause of future problems.

The vehicle should be brought to a stop in the fol-
lowing manner when brake performance has deteri-
orated while driving.
• Press the brake pedal harder than usual.
• Should the brakes fail, shift down to a lower gear
to reduce your speed and slowly pull the parking
brake lever to park your vehicle. Press the brake
pedal to operate your rear brake lights to alert
vehicles behind you.CAUTION
!
CAUTION
!
Driving for a long time with the engine malfunction
indicator on may cause more damage to the emission
control system. This could also affect fuel economy
and drivability.
If this indicator does not come on when the ignition
key is turned to the “ON” position, have the system
checked by an authorized Mitsubishi Motors dealer
or a repair facility of your choice.
If the indicator comes on while the engine is run-
ning, avoid driving at high speeds.
During vehicle operation with the indicator on, the
vehicle may not accelerate when you depress the
accelerator pedal.
When the vehicle is stationary with the indicator on,
you must depress the brake pedal more firmly than
usual since the engine idling speed is higher than
usual and the vehicle with an automatic transaxle
has a stronger tendency to creep forward.

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.
