Ignition Positions
Use the key to turn the ignition switch to
four different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:If your key seems stuck in LOCK and
you cannot turn it, be sure you are using
the correct key; if so, is it all the way in? Turn
the key only with your hand. Using a tool to
force it could break the key or the ignition
switch. If none of these works, then your
vehicle needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Lengthy operation of features such as the radio in
the accessory ignition position may drain the
battery and prevent your vehicle from starting.
Do not operate your vehicle in the accessory
ignition position for a long period of time.
C (RUN):This is the position for driving.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.

The player is able to read and play a maximum
of 50 folders, 50 playlists, 10 sessions, and
255 les. Long le names, folder names, or playlist
names can use more disc memory space than
necessary. To conserve space on the disc,
minimize the length of the le, folder, or playlist
names. You can also play an MP3 CD that
was recorded using no le folders. The system
can support up to 11 folders in depth, though, keep
the depth of the folders to a minimum in order
to keep down the complexity and confusion
in trying to locate a particular folder during
playback. If a CD contains more than the
maximum of 50 folders, 50 playlists, 10 sessions,
and 255 les the player lets you access and
navigate up to the maximum, but all items over
the maximum are ignored.
Root Directory
The root directory is treated as a folder. If the root
directory has compressed audio les, the directory
displays 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 contains only compressed les, the
les are located under the root folder. The next
and previous folder functions do not function on a
CD that was recorded without folders or playlists.
When displaying the name of the folder the
radio displays ROOT.
When the CD 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.

Drunken Driving
Death and injury associated with drinking and
driving is a national tragedy. It is the number
one contributor to the highway death toll,
claiming thousands of victims every year.
Alcohol affects four things that anyone needs to
drive a vehicle:
Judgment
Muscular Coordination
Vision
Attentiveness
Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most
cases, these deaths are the result of someone who
was drinking and driving. In recent years, more
than 16,000 annual motor vehicle-related deaths
have been associated with the use of alcohol, with
more than 300,000 people injured.Many adults — by some estimates, nearly half
the adult population — choose never to drink
alcohol, so they never drive after drinking.
For persons under 21, it is against the law in
every U.S. state to drink alcohol. There are good
medical, psychological, and developmental
reasons for these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink
alcohol and then drive. But what if people do?
How much is “too much” if someone plans
to drive? It is a lot less than many might think.
Although it depends on each person and situation,
here is some general information on the problem.
The Blood Alcohol Concentration (BAC) of
someone who is drinking depends upon
four things:
The amount of alcohol consumed
The drinker’s body weight
The amount of food that is consumed before
and during drinking
The length of time it has taken the drinker to
consume the alcohol

Driving Across an Incline
Sooner or later, an off-road trail will probably go
across the incline of a hill. If this happens,
you have to decide whether to try to drive across
the incline. Here are some things to consider:
A hill that can be driven straight up or down
may be too steep to drive across. When you
go straight up or down a hill, the length of the
wheel base — the distance from the front
wheels to the rear wheels — reduces the
likelihood the vehicle will tumble end over end.
But when you drive across an incline, the much
more narrow track width — the distance
between the left and right wheels — may not
prevent the vehicle from tilting and rolling over.
Also, driving across an incline puts more weight
on the downhill wheels. This could cause a
downhill slide or a rollover.
Surface conditions can be a problem when you
drive across a hill. Loose gravel, muddy spots,
or even wet grass can cause the tires to slip
sideways, downhill. If the vehicle slips
sideways, it can hit something that will
trip it — a rock, a rut, etc. — and roll over.
Hidden obstacles can make the steepness of
the incline even worse. If you drive across a
rock with the uphill wheels, or if the downhill
wheels drop into a rut or depression, your
vehicle can tilt even more.
For reasons like these, you need to decide
carefully whether to try to drive across an incline.
Just because the trail goes across the incline
does not mean you have to drive it. The last
vehicle to try it might have rolled over.
{CAUTION:
Driving across an incline that is too steep
will make your vehicle roll over. You could
be seriously injured or killed. If you have
any doubt about the steepness of the
incline, do not drive across it. Find another
route instead.
