the compass will be illuminated where the compass
reading is normally displayed.
All Segments Illuminated
To calibrate the compass, in an area free from

turns.
The calibration symbol will turn off and the compass
reading will be displayed.

INST ECON (Instantaneous Fuel Economy):
This shows fuel economy for the most recent second
of driving.

RANGE (Trip Range): This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based on
the last few hours of driving. When in a low fuel
condition, LO is displayed.

FUEL USED (Trip Fuel Used): This shows the
accumulated fuel used since the last reset.

AVG SPEED (Average Speed): This shows the
average speed since the last reset.
Resetting the Trip Computer

Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off.
See ªRetained Accessory Powerº in the Index.

Your audio system is equipped with a Radio Data System
(RDS). RDS is a system that receives data along with
the audio of the FM station you are currently tuned to.
RDS displays program information and can control your
radio. With RDS, the radio can do the following:

Seek only to stations with the types of programs
you want to listen to,

seek to stations with traffic announcements,

receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.
RDS features are only available on FM stations that
broadcast RDS information. The RDS features on your
radio rely on receiving specific RDS information from
these stations. These features will only work when the
RDS 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.
When you are tuned to an RDS station, the station
name will appear on the display, instead of the
frequency. Most RDS stations provide their station
name, the time of day and a Program Type (PTY) for
their current programming. Some stations also provide
the name of the current program.
