Using the Auxiliary Input Jack
Your radio system has an auxiliary input jack located
on the lower right side of the faceplate. This is not an
audio output; do not plug the headphone set into the front
auxiliary input jack. An external audio device such as an
iPod, laptop computer, MP3 player, CD changer, etc. can
be connected to the auxiliary input jack for use as another
source for audio listening.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in PARK (P). SeeDefensive Driving
on page 4-2for more information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio’s front auxiliary input jack.
When a device is connected, press the radio CD/AUX
button to begin playing audio from the device over
the vehicle speakers.
O(Power/Volume):Turn clockwise or
counterclockwise to increase or decrease the volume of
the portable player. You might need to do additional
volume adjustments from the portable device if the
volume is not loud or soft enough.
BAND:Press to listen to the radio while a portable audio
device is playing. The portable audio device continues
playing, so you might want to stop it or turn it off.CD/AUX (CD/Auxiliary):Press to play a CD while a
portable audio device is playing. Press again and the
system begins playing audio from the connected portable
audio player. If a portable audio player is not connected,
the message No Aux Input Device displays.
Using an MP3
MP3 CD-R or CD-RW Disc
The radio plays MP3 files that were recorded on a
CD-R or CD-RW disc. The files can be recorded with
the following fixed bit rates: 32 kbps, 40 kbps, 56 kbps,
64 kbps, 80 kbps, 96 kbps, 112 kbps, 128 kbps,
160 kbps, 192 kbps, 224 kbps, 256 kbps, and 320 kbps or
a variable bit rate. Song title, artist name, and album are
available for display by the radio when recorded using
ID3 tags version 1 and 2.
Compressed Audio
The radio also plays discs that contain both
uncompressed CD audio (.CDA files) and MP3 files.
By default the radio shows the MP3 label on the left side
of the screen but plays both file formats in the order
in which they were recorded to the disc.
3-77

MP3 Format
If you burn your own MP3 disc on a personal computer:
•Make sure the MP3 files are recorded on a CD-R
or CD-RW disc.
•Do not mix standard audio and MP3 files on
one disc.
•The CD player is able to read and play a maximum
of 50 folders, 15 playlists, and 512 folders and files.
•Create a folder structure that makes it easy to find
songs while driving. Organize songs by albums
using one folder for each album. Each folder
or album should contain 18 songs or less.
•Avoid subfolders. The system can support up to
eight subfolders deep, however, keep the total
number of folders to a minimum in order to reduce
the complexity and confusion in trying to locate
a particular folder during playback.
•Make sure playlists have a .mp3 or .wpl extension
(other file extensions might not work).
•Minimize the length of the file, folder, or playlist
names. Long file, folder, or playlist names, or a
combination of a large number of files and folders,
or playlists could cause the player to be unable
to play up to the maximum number of files, folders,
playlists, or sessions. If you wish to play a large
number of files, folders, playlists or sessions,
minimize the length of the file, folder, or playlist
name. Long names also take up more space on
the display, potentially getting cut off.
•Finalize the audio disc before you burn it. Trying to
add music to an existing disc could cause the disc
not to function in the player.
Playlists can be changed by using the
Sc(previous)
and
cT(next) folder buttons, thefknob, or
the
©SEEK¨arrows. You can also play an MP3
CD-R or CD-RW that was recorded using no file folders.
If a CD-R or CD-RW contains more than the maximum
of 50 folders, 15 playlists, and 512 folders and files, the
player lets you access and navigate up to the maximum,
but all items over the maximum are not accessible.
3-78

Root Directory
The root directory of the CD-R or CD-RW is treated as a
folder. If the root directory has compressed audio files,
the directory displays as the CD label. All files contained
directly under the root directory are accessed prior to any
root directory folders. However, playlists (Px) are always
accessed before root folders or files.
If a disc contains both uncompressed CD audio (.CDA)
and MP3 files, a folder under the root directory called
CD accesses all of the CD audio tracks on the disc.
Empty Directory or Folder
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and
no compressed files directly beneath them, the player
advances to the next folder in the file structure that
contains compressed audio files. The empty folder
does not display.
No Folder
When the CD contains only compressed files, the files
are located under the root folder. The next and previous
folder function does not display on a CD that was
recorded without folders or playlists.
When the CD contains only playlists and compressed
audio files, but no folders, all files are located under
the root folder. The folder down and up buttons search
playlists (Px) first and then goes to the root folder.
Order of Play
Tracks recorded to the CD-R or CD-RW are played in
the following order:
•Play begins from the first track in the first playlist
and continues sequentially through all tracks in
each playlist. When the last track of the last playlist
has played, play continues from the first track of
the first playlist.
•Play begins from the first track in the first folder
and continues sequentially through all tracks in each
folder. When the last track of the last folder has
played, play continues from the first track of the
first folder.
When play enters a new folder, the display does
not automatically show the new folder name unless you
have chosen the folder mode as the default display.
The new track name displays.
File System and Naming
The song name that displays is the song name that is
contained in the ID3 tag. If the song name is not present
in the ID3 tag, then the radio displays the file name
without the extension (such as .mp3) as the track name.
Track names longer than 32 characters or four pages
are shortened. Parts of words on the last page of
text and the extension of the filename does not display.
3-79

Preprogrammed Playlists
Preprogrammed playlists that were created using
WinAmp™, MusicMatch™, or Real Jukebox™ software
can be accessed, however, they cannot be edited
using the radio. These playlists are treated as special
folders containing compressed audio song files.

could take several minutes to scan the disc depending on
the number of MP3 files recorded to the CD-R or CD-RW.
The radio can begin playing while it is scanning the disc
in the background. When the scan is finished, the CD-R
or CD-RW begins playing again.
Once the disc has scanned, the player defaults to playing
MP3 files in order by artist. The current artist playing is
shown on the second line of the display between thearrows. Once all songs by that artist are played, the

Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS), if your
vehicle has this feature, is designed to warn the driver
when a low tire pressure condition exists. TPMS sensors
are mounted onto each tire and wheel assembly,
excluding the spare tire and wheel assembly. The TPMS
sensors monitor the air pressure in the vehicle’s tires
and transmits the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS will illuminate the
low tire pressure warning
symbol located on the
instrument panel cluster.
At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and
the DIC warning message come on at each ignition cycle
until the tires are inflated to the correct inflation pressure.If your vehicle has DIC buttons, tire pressure levels can
be viewed by the driver. For additional information and
details about the DIC operation and displays seeDIC
Operation and Displays on page 3-42andDIC Warnings
and Messages on page 3-49.
The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then turn
off as you start to drive. This could be an early indicator
that the air pressure in the tire(s) are getting low and
need to be inflated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct inflation pressure for
your vehicle’s tires when they are cold. SeeLoading
Your Vehicle on page 4-20, for an example of the Tire
and Loading Information label and its location on your
vehicle. Also seeInflation - Tire Pressure on page 5-60.
Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-68andTires on page 5-53.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.
5-64

TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
flashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until the
problem is corrected. Some of the conditions that can
cause the malfunction light and DIC message to
come on are:
•One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re-install the road
tire containing the TPMS sensor.
•The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
•One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
•Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. SeeBuying New Tires on page 5-70.
•Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signal
a low tire condition. See your dealer/retailer for service if
the TPMS malfunction light and DIC message comes on
and stays on.
5-65

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you rotate your vehicle’s tires or replace one or
more of the TPMS sensors, the identification codes will
need to be matched to the new tire/wheel position. The
sensors are matched to the tire/wheel positions in the
following order: driver side front tire, passenger side front
tire, passenger side rear tire, and driver side rear tire
using a TPMS diagnostic tool. See your dealer/retailer
for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tire’s
air pressure. If increasing the tire’s air pressure, do not
exceed the maximum inflation pressure indicated on the
tire’s sidewall.
To decrease air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air pressure
gage, or a key.You have two minutes to match the first tire/wheel
position, and five minutes overall to match all
four tire/wheel positions. If it takes longer than
two minutes, to match the first tire and wheel, or more
than five minutes to match all four tire and wheel
positions the matching process stops and you need to
start over.
The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press the Remote Keyless Entry (RKE) transmitter’s
LOCK and UNLOCK buttons at the same time for
approximately five seconds. The horn sounds twice
to signal the receiver is in relearn mode and
TIRE LEARNING ACTIVE message displays on the
DIC screen.
5-66

If your vehicle does not have RKE, press the Driver
Information Center (DIC) vehicle information button
until the PRESS
VTO RELEARN TIRE POSITIONS
message displays. The horn sounds twice to signal
the receiver is in relearn mode and TIRE LEARNING
ACTIVE message displays on the DIC screen.
If your vehicle does not have RKE or DIC buttons,
press the trip odometer reset stem located on the
instrument panel cluster until the PRESS
VTO
RELEARN TIRE POSITIONS message displays.
The horn sounds twice to signal the receiver is in
relearn mode and TIRE LEARNING ACTIVE
message displays on the DIC screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for five seconds,
or until a horn chirp sounds. The horn chirp, which
may take up to 30 seconds to sound, confirms that
the sensor identification code has been matched to
this tire and wheel position.6. Proceed to the passenger side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the
procedure in Step 5. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and that the
TPMS sensor matching process is no longer active.
The TIRE LEARNING ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.
