Engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”)
N00520500703
This indicator is a part of the onboard diagnostic (OBD) sys-
tem which monitors the emissions, engine control system or
continuously variable transmission (CVT) control system/Twin
Clutch SST 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 a few seconds later.
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.


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.


Do not suddenly apply the parking brake while driv-
ing. This may cause the rear wheels to lock and
cause an accident.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
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.

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.
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 equipped with a CVT or a Twin
Clutch SST has a stronger tendency to creep for-
ward.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.

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 engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”) is on.
Spark plugs
N00940900202
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 9-8 or plugs that are exactly the same. Other
plugs could cause engine damage, performance problems
or radio noise.
