Wiper Blades; Emission-Control System Maintenance; Spark Plugs - Mitsubishi MIRAGE Service Manual

Wiper blades

Check the wiper blades occasionally. Clean
them regularly to remove deposits of salt and
road film. Use a sponge or cloth and a mild
detergent or non-abrasive cleaner to clean the
blades and glass areas.
Replace the blades if they continue to streak
or smear.
NOTE
 Do not run the wipers on dry glass for a long
time. This wears out the rubber and can
scratch the glass.
During cold weather
If the blades are frozen to the windshield or
rear window, do not operate the wipers until
the ice has melted and the blades are freed,
otherwise the wiper motor may be damaged.
Emission-control system
maintenance
Your vehicle is equipped with an emission-
control system that meets all the requirements
of the U.S. Environmental Protection Agency
and Environment Canada. The emission-con-
trol system is made of:
N00940700138
 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 Mitsubishi
Motors dealer or a repair facility of your
choice. 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.

Wiper blades
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

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 MAINTENANCE
MANUAL".
NOTE
 Use the spark plugs listed under "Engine
specifications" on page 11-4 or plugs that are
exactly the same. Other plugs could cause
engine damage, performance problems or
radio noise.
