Playing a CD (In Either the DVD
or CD Slot)
Insert a CD partway into the slot, label side up.
The player pulls it in and the CD should begin
playing (loading a disc into the system,
depending on media type and format ranges from
5 to 20 seconds for a CD, and up to 30 seconds
for a DVD to begin playing).
If the ignition or radio is turned off, with a CD in
the player, it stays in the player. When the ignition
or radio is turned on, the CD starts playing
where it stopped, if it was the last selected audio
source. The CD is controlled by the buttons
on the radio faceplate or by the RSA unit. See
Rear Seat Audio (RSA) on page 345for more
information. The DVD/CD decks, (upper slot is the
DVD deck and the lower slot is the CD deck) of
the radio are compatible with most audio CDs,
CD-R, CD-RW, and MP3s.
When a CD is inserted, the text label DVD or
CD symbol appears on the left side of the radio
display. As each new track starts to play, the
track number appears on the display.The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs
and the smaller CDs are loaded in the same
manner.
If playing a CD-R, the sound quality can be
reduced due to CD-R quality, the method of
recording, the quality of the music that has been
recorded, and the way the CD-R has been
handled. There can be an increase in skipping,
difficulty in nding tracks, and/or difficulty in loading
and ejecting. If these problems occur, check
the bottom surface of the CD. If the surface of
the CD is damaged, such as cracked, broken,
or scratched, the CD will not play properly.
If the surface of the CD is soiled, seeCare of
Your CDs and DVDs on page 349for more
information.
If there is no apparent damage, try a known
good CD.

Notice:If a label is added to a CD, or more
than one CD is inserted into the slot at a time,
or an attempt is made to play scratched
or damaged CDs, the CD player could be
damaged. While using the CD player, use only
CDs in good condition without any label,
load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
Do not add any label to a CD, it could get caught

Care of Your CDs and DVDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans
the bottom surface of the disc. If the surface of a
CD is damaged, such as cracked, broken, or
scratched, the CD does not play properly or not
at all. If the surface of a CD is soiled, take a soft,
lint free cloth or dampen a clean, soft cloth in
a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface.
Pick up CDs by grasping the outer edges or
the edge of the hole and the outer edge.
Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the
lens of the CD optics with lubricants internal to
the CD mechanism.
Fixed Mast Antenna
The xed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast
is still tightened to its base. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear
of snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the best
performance from the XM™ system if the sunroof
is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the
lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a
major storm system?
Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with
a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your vehicle’s mirrors
and instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the
chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when
you’re pulling a trailer. See the Maintenance
Schedule for more on this. Things that are
especially important in trailer operation are
automatic transmission uid (don’t overll), engine
oil, axle lubricant, belts, cooling system and
brake system. Each of these is covered in this
manual, and the Index will help you nd them
quickly. If you’re trailering, it’s a good idea
to review these sections before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.

For good starting and heater efficiency below
32°F (0°C), the fuel mix in the fuel tank should
contain no more than 70% ethanol. It is best not
to alternate repeatedly between gasoline and E85.
If you do switch fuels, it is recommended that
you add as much fuel as possible — do not add
less than three gallons (11 L) when refueling.
You should drive the vehicle immediately
after refueling for at least seven miles (11 km)
to allow the vehicle to adapt to the change
in ethanol concentration.
E85 has less energy per gallon than gasoline, so
you will need to rell your fuel tank more often
when using E85 than when you are using gasoline.
SeeFilling the Tank on page 440.
Notice:Some additives are not compatible
with E85 fuel and may harm your vehicle’s fuel
system. Damage caused by additives would
not be covered by your new vehicle warranty.
Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in the fuel system and also damage
plastic and rubber parts. That damage would
not be covered under your warranty.Fuels in Foreign Countries
If you plan on driving in another country outside
the United States or Canada, the proper fuel
might be hard to nd. Never use leaded gasoline
or any other fuel not recommended in the
previous text on fuel. Costly repairs caused by
use of improper fuel would not be covered by
your warranty.
To check the fuel availability, ask an auto club,
or contact a major oil company that does business
in the country where you will be driving.
