Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle’s safety belts.The manufacturer’s instructions that
come with the booster seat, state
the weight and height limitations for
that booster. Use a booster seat
with a lap-shoulder belt until
the child passes the below t test:
Sit all the way back on the
seat. Do the knees bend at the
seat edge? If yes, continue.
If no, return to the booster seat.
Buckle the lap-shoulder belt.
Does the shoulder belt rest on the
shoulder? If yes, continue. If no,
try using the rear safety belt
comfort guide. See “Rear Safety
Belt Comfort Guides” under
Lap-Shoulder Belt on page 1-23
for more information. If the
shoulder belt still does not rest on
the shoulder, then return to the
booster seat.
Does the lap belt t low and snug
on the hips, touching the thighs?
If yes, continue. If no, return to the
booster seat.
Can proper safety belt t be
maintained for the length of the
trip? If yes, continue. If no, return
to the booster seat.
Q:What is the proper way to
wear safety belts?
A:An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder
belt can provide. The shoulder
belt should not cross the face or
neck. The lap belt should t
snugly below the hips, just
touching the top of the thighs.
This applies belt force to
the child’s pelvic bones in a
crash. It should never be worn
over the abdomen, which
could cause severe or even fatal
internal injuries in a crash.

Guides” underLap-Shoulder Belt

Seats and Restraint System 1-29

Notice:The engine is designed
to work with the electronics
in the vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer/retailer. If you do not, the
engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. Some models
may have an internal thermostat in
the cord which will prevent
engine coolant heater operation at
temperatures above 0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
located on the driver side of the
engine compartment. It is
routed around the windshield
washer uid reservoir.
3. Plug the cord into a normal,
grounded 110-volt AC outlet.
{CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a re. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet. If
the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine
parts. If you do not, it could be
damaged.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
Features and Controls 2-23

The CD player is able to read
and play a maximum of
50 folders, 15 playlists, and a
combined total of 512 folders
and les.
Create a folder structure that
makes it easy to nd 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 le
extensions might not work).
Minimize the length of the le,
folder, or playlist names. Long le,
folder, or playlist names, or a
combination of a large number of
les and folders, or playlists could
cause the player to be unable toplay up to the maximum number
of les, folders, playlists, or
sessions. To play a large number
of les, folders, playlists or
sessions, minimize the length of
the le, folder, or playlist name.
Long names also take up more
space on the display, potentially
getting cut off.
Finalize the audio disc before
burning it. Trying to add music to
an existing disc could cause the
disc not to function in the player.
Change playlists by using
Sc
andcTfolder buttons, the
fknob, or the SEEK arrows.
An MP3/WMA CD-R or CD-RW that
was recorded using no le folders
can be played. If a CD-R or CD-RW
contains more than the maximum
of 50 folders, 15 playlists, and
a combined total of 512 folders and
les, the player accesses and
navigates up to the maximum, but
all items over the maximum are
not accessible.Root Directory
The root directory of the CD-R or
CD-RW is treated as a folder. If the
root directory has compressed
audio les, the directory displays
as the CD label. All les contained
directly under the root directory
are accessed prior to any root
directory folders. However, playlists
(Px) are always accessed before
root folders or les.
If a disc contains both uncompressed
CD audio (.CDA) and MP3/WMA
les, 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 le structure
that contains only folders/subfolders
and no compressed les directly
beneath them, the player advances
to the next folder in the le
structure that contains compressed
audio les. The empty folder
does not display.

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 .m3u, .wpl or .pls extension
as other le extensions might
not work.
Minimize the length of the le,
folder or playlist names. Long le,
folder, or playlist names, or a
combination of a large number of
les and folders, or playlists could
cause the player to be unable to
play up to the maximum number
of les, folders, playlists, or
sessions. To play a large number
of les, folders, playlists, or
sessions, minimize the length of
the le, folder, or playlist name.
Long names also take up more
space on the display, potentially
getting cut off.
Finalize the audio disc before
burning it. Trying to add music to
an existing disc could cause the
disc not to function in the player.
Root Directory
The root directory of the CD-R or
CD-RW disc is treated as a folder.
If the root directory has compressed
audio les, the directory is displayed
as F1 ROOT. All les contained
directly under the root directory are
accessed prior to any root directory
folders. However, playlists (Px) are
always accessed before root folders
or les.
Empty Directory or Folder
If a root directory or a folder exists
somewhere in the le structure
that contains only folders/subfolders
and no compressed les directly
beneath them, the player advances
to the next folder in the le
structure that contains compressed
audio les. The empty folder
does not display.No Folder
When the CD-R or CD-RW disc
contains only compressed les, the
les are located under the root
folder. The next and previous folder
function does not function on a
CD-R or CD-RW that was recorded
without folders or playlists. When
displaying the name of the folder the
radio displays ROOT.
When the CD-R or CD-RW disc
contains only playlists and
compressed audio les, but no
folders, all les are located under
the root folder. The folder down and
the folder up buttons search
playlists (Px) rst and then goes to
the root folder. When the radio
displays the name of the folder the
radio displays ROOT.
