Engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”)
N00520500732
This indicator is a part of the onboard diagnostic (OBD) sys-
tem which monitors the emissions, engine control system or
automatic transaxle control system/continuously variable trans-
mission (CVT) control system. If a problem is detected in one
of these systems, this indicator comes on. When the ignition
switch is turned to the “ON” position, this indicator normally
comes on and goes off after the engine has started.
This indicator will come on if the fuel tank filler cap is not
properly tightened. If this 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.
CAUTION
!If the brake warning light and the Anti-lock braking
system warning light are illuminated at the same
time, the braking force distribution function will not
operate, so the vehicle may be destabilized during
sudden braking under the following conditions.
• When the brake warning light does not go out even
when the parking brake is released.
• When the brake warning light stays on while driv-
ing.
• If the above occurs, avoid sudden braking and
high-speed driving. Park the vehicle in a safe
place, and contact an authorized Mitsubishi
Motors dealer or a repair facility of your choice as
soon as possible.
The vehicle should be brought to a halt in the follow-
ing manner when brake performance is deterio-
rated.
• Confirm that the vehicle slows down when you
press down on the brake pedal harder than usual.
In some cases, the brake pedal may go all the way
to the floor.
• Should the brakes fail, use engine braking to
reduce your speed and slowly apply the parking
brake.
Depress the brake pedal to illuminate the stop
lights to alert the vehicles behind you.
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
switch is turned to the “ON” position, have the sys-
tem checked at an authorized Mitsubishi Motors
dealer or a repair facility of your choice.

NOTEDo 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.
Charging system warning light
N00520600296
This light comes on in the event of a malfunction in the charg-
ing system or when the ignition switch is turned to the “ON”
position (engine off). A warning is also displayed in the multi-
information display. When the engine is started, the light
should go out. Check to make sure that the light has gone out
before driving.
If the engine malfunction indicator comes on while
the engine is running, 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 a vehicle with an automatic transaxle or
CVT has a stronger tendency to creep forward.
CAUTION
!
CAUTION
!If the warning light stays on while the engine is run-
ning, park your vehicle in a safe place as soon as
possible and contact an authorized Mitsubishi
Motors dealer or a repair facility of your choice to
have the system checked.

Vehicle care and maintenance
7-35
7 Emission-control system maintenance
N00940800328
Your vehicle is equipped with an emission-control system that
meets all the requirements of the U.S. Environmental Protec-
tion Agency and Environment Canada. The emission-control
system is made of:
a positive crankcase ventilation system
an evaporative emission-control system
an exhaust emission-control system
To be sure the emission-control system works properly, have
your vehicle inspected and maintained by an authorized Mit-
subishi Motors dealer or a repair facility of your choice. This
should be done at the time or mileage specified in the “WAR-
RANTY AND MAINTENANCE MANUAL”.
These, and all the other “general” maintenance services listed
in this manual, need to be performed to keep your vehicle run-
ning properly and reliably.
You should also have an inspection and service any time you
suspect a malfunction.NOTETo 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 engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”) is ON.
Spark plugs
N00940900231
Spark plugs must fire properly to ensure proper engine perfor-
mance and emission-control.
Do not reuse spark plugs by cleaning or regapping. Spark plugs
should be replaced at the mileage specified in the “WAR-
RANTY AND MAINTENANCE MANUAL”.NOTEUse the recommended or equivalent spark plugs listed
under “Engine specifications” on page 9-9. Use of other
plugs could cause engine damage, loss of performance or
radio noise.Fuel hoses
N00941000040
Check the hose surfaces for any heat and mechanical damage,
hard and brittle rubber, cracking, tears, cuts and abrasions. Pay
special 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
N00950100050
Have the valve clearance checked at an authorized Mitsubishi
Motors dealer at the mileage specified in the “WARRANTY
AND MAINTENANCE MANUAL”.
If the engine sounds abnormally loud, have adjustments made
by an authorized Mitsubishi Motors dealer.
