FM signals, unlike AM signals, are reflected by solid objects such as buildings, etc. Because FM signals are easily reflected by buildings, this can al
so cause reception dis-
turbances. The direct signal from the broadcast station reaches the antenna slightly before thereflected signal. This time difference may cause some reception disturbance or flutter. This problem occurs primarily in urban areas.
If one listens to a weak station and is in the vicinity of another strong station, both sta- tions might be received simultaneously. Stereo reception requires a high quality broadcast signal. This means that types of disturbances mentioned previously become more marked and the reception range issomewhat diminished during stereo recep- tion. FM reception is affected by the electrical sys- tems of vehicles in the vicinity, especially those without an electronic noise suppression
device. The disturbance is even greater if the station is weak or poorly tuned. FM reception is not as sensitive to electrical disturbances as AM. AM reception is sensi-tive to electrical disturbances such as power lines, lightning and other types of similar electrical phenomena.

Check the wiper blades occasionally. Clean them regularly to remove deposits of salt androad 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. 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.

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: a positive crankcase ventilation system an evaporative emission-control system an exhaust emission-control system
The maintenance services listed in the “WARRANTY AND MAINTENANCE MANUAL” must be performed at the times or mileages listed to keep the emission-con-trol system working properly. These, and allthe other “general” maintenance services listed in this manual, need to be performed to keep your vehicle running properly and reli-ably. You may need more frequent maintenance if you drive your vehicle in harsh conditions such as dusty areas or
do a lot of start-and-
stop driving. To be sure the emission-control system works properly, have your vehicle inspected and maintained by an authorized MitsubishiMotors dealer or a repair facility of your choice following the schedule in the “WAR- RANTY AND MAINTENANCE MAN-UAL”. You should also have an inspection and ser- vice any time you suspect a malfunction.

Spark plugs must fire properly for goodengine performance and emission-control.Do not reuse them by cleaning or regapping. Change them at the mileage listed in the “WARRANTY AND MAINTENANCEMANUAL”.
Wiper blades
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 Emission-control system maintenance
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 rapiddiagnosis 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 spark plugs listed under “Engine specifications” on page 11-5 or plugs that are exactly the same. Other plugs could causeengine damage, performance problems or radio noise.
