2017 FORD EXPEDITION EL audio

If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically controlled by a computer,some control conditions are maintainedby power from the battery. When thebattery is disconnected or a new batteryis installed, the engine must relearn its idleand fuel trim strategy for optimumdriveability and performance. Flexible fuelvehicles (FFV) must also relearn theethanol content of the fuel for optimumdriveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While theengine is warming up, complete thefollowing: Reset the clock. See AudioSystem (page 313). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 79).Reset the radio station presets. SeeAudio System (page 313).
6.Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km)to completely relearn the idle trim andfuel trim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fueltrim strategy.
Note:For flexible fuel vehicles, if you areoperating on E85, you may experience poorstarts or an inability to start the engine anddriveability problems until the fuel trim andethanol content have been relearned.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
If storing your vehicle for more than 30days without recharging the battery, werecommend that you disconnect thebattery cables to maintain battery chargefor quick starting.

GENERAL INFORMATION
Radio Frequencies and ReceptionFactors
AM and FM frequencies are established bythe Federal Communications Commission(FCC) and the Canadian Radio andTelecommunications Commission (CRTC).Those frequencies are:
•AM: 530, 540-1700, 1710 kHz
•FM: 87.9-107.7, 107.9 MHz
Radio Reception Factors
The further you travel from an AM or FM station, theweaker the signal and the weaker the reception.Distance and strength
Hills, mountains, tall buildings, bridges, tunnels, freewayoverpasses, parking garages, dense tree foliage andthunderstorms can interfere with the reception.
Terrain
When you pass a ground-based broadcast repeatingtower, a stronger signal may overtake a weaker one andresult in the audio system muting.
Station overload
CD and CD Player Information
Note:CD units play commercially pressed4.7 in (12 cm) audio compact discs only. Dueto technical incompatibility, certainrecordable and re-recordable compact discsmay not function correctly when used inFord CD players.
Note:Do not insert CDs with homemadepaper (adhesive) labels into the CD playeras the label may peel and cause the CD tobecome jammed. You should use apermanent felt tip marker rather thanadhesive labels on your homemade CDs.Ballpoint pens may damage CDs. Pleasecontact an authorized dealer for furtherinformation.
Note:Do not use any irregularly shapeddiscs or discs with a scratch protection filmattached.
Always handle discs by their edges only.Clean the disc with an approved CDcleaner only. Wipe it from the center of thedisc toward the edge. Do not clean in acircular motion.
Do not expose discs to direct sunlight orheat sources for extended periods.
MP3 and WMA Track and FolderStructure
Audio systems capable of recognizing andplaying MP3 and WMA individual tracksand folder structures work as follows:
•There are two different modes for MP3and WMA disc playback: MP3 andWMA track mode (system default) andMP3 and WMA folder mode.
•MP3 and WMA track mode ignores anyfolder structure on the MP3 and WMAdisc. The player numbers each MP3and WMA track on the disc (noted bythe MP3 or WMA file extension) fromT001 to a maximum of T255. Themaximum number of playable MP3 andWMA files may be less depending onthe structure of the CD and exactmodel of radio present.

Audio System

•MP3 and WMA folder mode representsa folder structure consisting of onelevel of folders. The CD player numbersall MP3 and WMA tracks on the disc(noted by the MP3 or WMA fileextension) and all folders containingMP3 and WMA files, from F001 (folder)T001 (track) to F253 T255.
•Creating discs with only one level offolders helps with navigation throughthe disc files.
If you are burning your own MP3 and WMAdiscs, it is important to understand howthe system reads the structures you create.While various files may be present (fileswith extensions other than MP3 andWMA), only files with the MP3 and WMAextension are played; other files areignored by the system. This enables you touse the same MP3 and WMA disc for avariety of tasks on your work computer,home computer and your in-vehiclesystem.
In track mode, the system displays andplays the structure as if it were only onelevel deep (all MP3 and WMA files play,regardless of being in a specific folder). Infolder mode, the system only plays theMP3 and WMA files in the current folder.

DIGITAL RADIO
Note:HD Radio broadcasts are notavailable in all markets.
HD Radio technology is the digitalevolution of analog AM/FM radio. Yoursystem has a special receiver that allowsit to receive digital broadcasts (whereavailable) in addition to the analogbroadcasts, it already receives. Digitalbroadcasts provide a better sound qualitythan analog broadcasts with free,crystal-clear audio and no static ordistortion. For more information, and aguide to available stations andprogramming, please visitwww.hdradio.com.
When HD Radio is on and you tune to astation broadcasting HD Radio technology,you may notice the HD Radio logo on yourscreen. When this logo is available, youmay also see Title and Artist fieldson-screen.
The multicast indicator appears in FMmode (only) if the current station isbroadcasting multiple digital broadcasts.The highlighted numbers signify availabledigital channels where new or differentcontent is available. HD1 signifies the mainprogramming status and is available inanalog and digital broadcasts. Othermulticast stations (HD2 through HD7) areonly available digitally.

Audio SystemE182082

When HD Radio broadcasts are active, youcan access the following functions:
•Scan allows you to hear a briefsampling of all available stations. Thisfeature still works when HD Radioreception is on, although it does notscan for HD2-HD7 channels. You maysee the HD logo appear if the stationhas a digital broadcast.
•Memory presets allow you to save anactive channel as a memory preset.Touch and hold a memory preset slotuntil the sound returns. There is a briefmute while the radio saves the station.Sound returns when finished. Whenswitching to an HD2 or HD3 memorypreset, the sound mutes before thedigital audio plays, because the systemhas to reacquire the digital signal.
Note:As with any saved radio station, youcannot access the saved station if yourvehicle is outside the station’s receptionarea.
HD Radio Reception and Station Troubleshooting
Potential reception issues
If you are listening to a multicast station and you are onthe fringe of the reception area, the station may mute dueto weak signal strength.
Reception area
If you are listening to HD1, the system switches back tothe analog broadcast until the digital broadcast is availableagain. However, if you are listening to any of the possibleHD2-HD7 multicast channels, the station mutes and staysmuted unless it is able to connect to the digital signalagain.
When the system first receives a station (aside from HD2-HD7 multicast stations), it first plays the station in theanalog version. Once the receiver verifies the station is anHD Radio station, it shifts to the digital version. Dependingon the station quality, you may hear a slight sound changewhen the station changes from analog to digital. Blendingis the shift from analog to digital sound or digital back toanalog sound.
Station blending
In order to provide the best possibleexperience, use the contact form to reportany station issues found while listening toa station broadcasting with HD Radiotechnology. Independent entities own andoperate each station. These stations areresponsible for ensuring all audio streamsand data fields are accurate.
