Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the RUN position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
The FUEL icon and arrow indicates
which side of the vehicle the fuel
filler door is located.
Refer toFilling the tankin theMaintenance and Specifications
chapter for more information.
Battery voltage gauge (manual
transmission only):Indicates the
battery voltage when the ignition is
in the RUN position. If the pointer
moves and stays outside the normal
operating range, have the vehicle’s
electrical system checked as soon as
possible.
Transmission fluid temperature gauge (automatic transmission
only):If the gauge is in the:
Normal area(normal) - the
transmission fluid is within the
normal operating temperature
(between “H” and “C”).
Yellow area(warning) — the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. snowplowing, towing
or off road use). Refer toSpecial
Operating Conditionsin the
scheduled maintenance
informationfor instructions. Operating the transmission for extended
periods of time with the gauge in the yellow area may cause internal
transmission damage.

2. Ensure that the battery in your portable music player is new or fully
charged and that the device is turned off.
3. Attach one end of the audio extension cable to the headphone output
of your player and the other end of the audio extension cable to the AIJ
in your vehicle.
4. Turn the radio on, using either a tuned FM station or a CD loaded into
the system. Adjust the volume to a comfortable listening level.
5. Turn the portable music player on and adjust the volume to 1/2 the
volume.
6. Press AUX on the vehicle radio repeatedly until LINE IN appears in
the display.
You should hear audio from your portable music player although it may
be low.
7. Adjust the sound on your portable music player until it reaches the
level of the FM station or CD by switching back and forth between the
AUX and FM or CD controls.
Troubleshooting:
1. Do not connect the audio input jack to a line level output. Line level
outputs are intended for connection to a home stereo and are not
compatible with the AIJ. The AIJ will only work correctly with devices
that have a headphone output with a volume control.
2. Do not set the portable music player’s volume level higher than is
necessary to match the volume of the CD or FM radio in your audio
system as this will cause distortion and will reduce sound quality. Many
portable music players have different output levels, so not all players
should be set at the same levels. Some players will sound best at full
volume and others will need to be set at a lower volume.
3. If the music sounds distorted at lower listening levels, turn the
portable music player volume down. If the problems persist, replace or
recharge the batteries in the portable music player.
4. The portable music player must be controlled in the same manner
when it is used with headphones as the AIJ does not provide control
(play, pause, etc.) over the attached portable music player.
5. For safety reasons, connecting or adjusting the settings on your
portable music player should not be attempted while the vehicle is
moving. Also, the portable music player should be stored in a secure
location, such as the center console or the glove box, when the vehicle is
in motion. The audio extension cable must be long enough to allow the
portable music player to be safely stored while the vehicle is in motion.
