O(Power/Volume):Turn this knob 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 does not go
loud or soft enough.
BAND:Press this button to listen to the radio
when a portable audio device is playing. The
portable audio device continues playing, so you
might want to stop it or power it off.

to cycle through DVD, CD, or Auxiliary when
listening to the radio. The DVD/CD text label and
a message showing track or chapter number
displays when a disc is in either slot. Press this
button again and the system automatically
searches for an auxiliary input device, such as a
portable audio player. If a portable audio player is
not connected, “No aux input device” displays.
If a disc is in both the DVD slot and the CD slot the
DVD/CD AUX button cycles between the two
sources and not indicate “No aux input device”.
If a front auxiliary device is connected, the
DVD/CD AUX button cycles through all available
options, such as: DVD slot, CD slot, Front
Auxiliary, and Rear Auxiliary (if available).See “Using the Auxiliary Input Jack(s)” later in this
section, or “Audio/Video (A/V) Jacks” under,
Rear Seat Entertainment System on page 311for
more information.
Using an MP3 (Radio with CD or
Six-Disc CD Player)
MP3/WMA CD-R or CD-RW Disc
The radio plays MP3/WMA les that were recorded
on a CD-R or CD-RW disc. The les can be
recorded with the following xed 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 les) and
MP3/WMA les. By default the radio shows the
MP3 label on the left side of the screen but
plays both le formats in the order in which
they were recorded to the disc.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chafing,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check
parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, fittings and clamps; replace with
genuine parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and
wiper blades, if contaminated. Replace wiper
blades that are worn or damaged. See Windshield
Wiper Blade Replacement on page 434and
Windshield, Backglass, and Wiper Blades on
page 484for more information.
(e)Make sure the safety belt reminder light and all
belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for any
other loose or damaged safety belt system parts.
If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced. Also
look for any opened or broken airbag coverings,
and have them repaired or replaced. The airbag
system does not need regular maintenance.
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring
anchor and release pawl, hood and door hinges,
rear folding seats, and liftgate hinges. More
frequent lubrication may be required when
exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean cloth
will make them last longer, seal better, and not
stick or squeak.
