Here are four things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage:
At the gas station, the pump shuts off before the
gage reads full.
It takes more, or less, fuel to ll up than the gage
reads. For example, the gage reads half full, but
it took more, or less, than half of the tank’s capacity
to ll it.
The gage pointer may move while cornering,
braking or accelerating.
The gage may not indicate empty when the ignition
is turned off.
Low Fuel Warning Light
If the vehicle’s fuel is low, a light on the instrument
panel cluster will come on and a chime will sound
periodically until fuel is added to the fuel tank.
It will also come on for a few seconds when the ignition
is turned on as a check to indicate it is working. If it
does not come on then, have it xed.United States

Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle’s engine, radio, or other systems, and
even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment that
has been added improperly.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off.
See “Retained Accessory Power (RAP)” under
Ignition Positions on page 2-18.
Setting the Time
Press and hold H until the correct hour appears on the

Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information.
With RDS, the radio can do the following:
Seek to stations broadcasting the selected type
of programming
Receive announcements concerning local and
national emergencies
Display messages from radio stations
Seek to stations with traffic announcements
This system relies upon receiving specic information
from these stations and will only work when the
information is available. In rare cases, a radio station
may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While the radio is tuned to an RDS station, the station
name or call letters will appear on the display
instead of the frequency. RDS stations may also
provide the time of day, a program type (PTY) for
current programming, and the name of the program
being broadcast.

SEEK arrow to select the PTY and take you to
the PTY’s rst station.
4. To go to another station within that PTY and the
PTY is displayed, press either SEEK arrow once.
If the PTY is not displayed, press either SEEK arrow
twice to display the PTY and then to go to
another station.
5. Press P-TYP to exit program type select mode.
If PTY times out and is no longer on the display,
go back to Step 1.
If both PTY and TRAF are on, the radio will
search for stations with the selected PTY and
traffic announcements.
