FM signals do not follow the earth surface nor are they reflected by the upper atmo- sphere. For this reason, FM broadcasts cannot be received over long distances. AM signalsfollow the earth’s surface and are reflected by the upper atmosphere. For this reason, AM broadcasts can be received over longer dis-tances.
Because of the limited
range of FM signals
and the way FM waves transmit, you mayexperience weak or fading FM reception. When the broadcast is blocked by mountains or similar obstructions, reception can be dis-turbed. The reason why one can hear FM but not AM in parking garages, under bridges etc., is that FM signals, unlike AM signals, are reflectedby solid objects such as buildings, etc. Because FM signals are easily reflected by buildings, this can also cause reception dis-turbances. The direct signal from the broadcast station reaches the antenna slightly before the
reflected 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.
CAUTION Changes or modifications not expressly approved by the party meeting the above conditions could void the user’s authority to operate the equipment.

Stereo reception requires a high quality broadcast signal. This means that types ofdisturbances mentioned previously become more marked and the reception range is somewhat 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 suppressiondevice. The disturbance is even greater if the station is weak or poorly tuned. FM reception is not as sensitive to electricaldisturbances as AM. AM reception is sensi- tive to electrical disturbances such as power
lines, lightning and other types of similar electrical phenomena.

Check the hose surfaces for any heat andmechanical damage, hard and brittle rubber,cracking, tears, cuts and abrasions. Pay spe- cial attention to the hoses closest to high heat sources such as the exhaust manifold. Checkall 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 ordamage, replace the hoses immediately.

Check these regularly for damage or leaks in the fuel lines and connections. Check the fuel tank filler cap for damage or looseness. Pay special attention to the fuel lines closest to
high heat sources such as the exhaust mani- fold.

The next pages list the maintenance servicerecommended by Mitsubishi Motors Corpo- ration. In addition to the general maintenance that needs to be performed at the times listed,
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.
