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” underLap-Shoulder
Belt on page 1-45for 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
length of trip? If yes, continue. If no, return to the
booster seat.
If you have the choice, a child should sit in a position
with a lap-shoulder belt and get the additional restraint a
shoulder belt can provide.

{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.
Active Fuel Management™
Vehicles with V8 engines may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders, depending
on the driving conditions.
When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing the vehicle to achieve better
fuel economy. When greater power demands are
required, such as accelerating from a stop, passing,
or merging onto a freeway, the system will maintain
full-cylinder operation.
If your vehicle has an Active Fuel Management™
indicator, seeDIC Operation and Displays (With DIC
Buttons) on page 3-52orDIC Operation and Displays
(Without DIC Buttons) on page 3-58for more information
on using this display.

The passenger’s temperature setting can be set to
match the driver’s temperature setting by pressing the
PASS button and turning off the PASS indicator.
When the passenger’s temperature setting is set
different than the driver’s setting, the indicator on the
PASS button illuminates and both the driver side
and passenger side temperature displays are shown.
Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO will
be lit on the display. The current delivery mode and
fan speed will also be displayed for approximately
5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet mayautomatically switch to recirculate inside air to help
quickly cool down the vehicle. The light on the
button comes on in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F (23°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver’s or
passenger’s temperature buttons to adjust the
temperature setting as necessary. If a temperature
setting of 60°F (15°C) is chosen, the system remains
at the maximum cooling setting. If a temperature
setting of 90°F (32°C) is chosen, the system remains
at the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to heat or
cool any faster.
Do not to cover the solar sensor located on the top
of the instrument panel near the windshield. This sensor
regulates air temperature based on sun load and also
turns on the headlamps. For more information on
the solar sensor, see “Sensors” later in this section.
To avoid blowing cold air in cold weather, the system will
delay turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Pressing the fan switch will override this
delay and change the fan to a selected speed.

Using an MP3 (Radio with CD or
Six-Disc CD Player)
MP3 CD-R or CD-RW Disc
The radio plays MP3 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 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.
MP3 Format
Burning an MP3 disc on a personal computer:
Make sure the MP3 les are recorded on a CD-R or
CD-RW disc.
Do not mix standard audio and MP3 les on one disc.
Make sure the CD does not have more than a
maximum of 50 folders, 15 playlists, and 512 folders
and les to read and play.
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 .m3u 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 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 contains only compressed les, the les
are located under the root folder. The next and previous
folder function does 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.

Driving Across an Incline
An off-road trail will probably go across the incline
of a hill. To decide whether to try to drive across
the incline, consider the following:
{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.
A hill that can be driven straight up or down might
be too steep to drive across. When going 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 driving across
an incline, the narrower track width — the distance
between the left and right wheels — might not
prevent the vehicle from tilting and rolling over.
Driving across an incline puts more weight on the
downhill wheels which could cause a downhill slide
or a rollover.
Surface conditions can be a problem. 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, the vehicle can tilt even more.
For these reasons, carefully consider 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.
If you feel the vehicle starting to slide sideways, turn
downhill. This should help straighten out the vehicle
and prevent the side slipping. The best way to prevent
this is to “walk the course” rst, so you know what
the surface is like before driving it.
