Your audio system is equipped with a Radio Data
System (RDS). RDS is a system that sends data along
with the audio of the FM station you are currently tuned
to. You can use RDS to display program information
and to 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 of 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, please contact the radio station.

3-37
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.
TUNE DISP: Press this control to change what appears
on the display while using RDS. Pressing this control
will also display an RDS station frequency or program
type when the radio is on. The display options are
station name, station frequency, PTY and the name of
the program (if available). Pressing and holding this
control will activate the RDS default display.
Accessing RDS Stations
To access RDS stations perform the following steps:
1. Push the SEEK TYPE button or turn the P
-TYPE
LIST AUDIO control to display the program
type list.
2. Turn the control either clockwise or
counterclockwise to select a program type. The list
is alphabetical. If you select ANY TYPE your radio
will seek to the first PTY available.
3. Push the SEEK TYPE button to activate search.VOL PWR: Turn this control clockwise to increase
volume when RDS interrupts regular play. Turn it
counterclockwise to decrease volume.
P
-TYPE LIST AUDIO: Turn this control clockwise or
counterclockwise to select the Program Type (PTY) you
want to listen to. TYPE and a PTY will appear on the
display. Press the SEEK TYPE button and the radio

program type. If the radio cannot find the desired
program type, NONE will appear on the display and the
radio will return to the last station you were listening to.
AM FM: The AM FM button operates the alternate
frequency feature. This feature allows the radio to
switch automatically to a stronger station with the same
programming. Alternate frequency is off by default from
the factory. Press and hold AM FM for two seconds to

will appear on the display and the radio will beep once.

hubs. Remove the tape. Hold the tape with the
open end down and try to turn the right hub
counterclockwise with a pencil. Turn the tape over

necessary, to overcome noise at any particular speed.
The volume level should always sound the same to you
as you drive. If you don't want to use automatic volume,
select OFF.

sounds the same to you. To use automatic volume, press
the AUTO VOL button until AVOL ON appears on the
display. To turn automatic volume off, press the AUTO
VOL button until AVOL OFF appears on the display.

3-55 Rear Seat Audio (If Equipped)
This feature allows rear seat passengers to listen to any
of the music sources including AM
-FM, cassette tapes
or CDs and to use automatic tone control. The rear seat
passengers can only control the music sources that the
front seat passengers are not listening to. For example,
rear seat passengers may listen to a cassette tape or CD
through headphones while the driver listens to the radio
through the front speakers. The rear seat passengers
have control of the volume for each set of headphones.
The front seat audio controls always override the rear
seat audio controls.This feature is intended for rear seat passengers.
The following functions are controlled by the rear seat
audio system buttons:
PWR: Press this button to turn the rear seat audio
system on or off. The rear speakers will be muted when
the power is turned on unless you have a Bose


equipped vehicle. You may operate the rear seat audio
functions even when the primary radio power is off.

counterclockwise to decrease volume. The left VOL
knob controls the left headphone and the right VOL
knob controls the right headphone.

An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o'clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
Off-Road Recovery
You may find that your right wheels have dropped off the
edge of a road onto the shoulder while you're driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way,
steer so that your vehicle straddles the edge of the
pavement. You can turn the steering wheel up to
one
-quarter turn until the right front tire contacts the
pavement edge. Then turn your steering wheel to go
straight down the roadway.

Q:What should I do if my vehicle stalls, or is about
to stall, and I can't make it up the hill?
A:If this happens, there are some things you should
do, and there are some things you must not do.
First, here's what you should do:

Push the brake pedal to stop the vehicle and
keep it from rolling backwards. Also, apply the
parking brake.

If your engine is still running, shift the transmission
to REVERSE (R), release the parking brake, and
slowly back down the hill in REVERSE (R).

If your engine has stopped running, you'll need
to restart it. With the brake pedal pressed and the
parking brake still applied, shift the transmission
to PARK (P) and restart the engine. Then, shift
to REVERSE (R), release the parking brake, and
slowly back down the hill as straight as possible
in REVERSE (R).
As you are backing down the hill, put your left hand
on the steering wheel at the 12 o'clock position. This
way, you'll be able to tell if your wheels are straight
and maneuver as you back down. It's best that you
back down the hill with your wheels straight rather
than in the left or right direction. Turning the wheel
too far to the left or right will increase the possibility
of a rollover.
Here are some things you must not do if you stall,
or are about to stall, when going up a hill.

Never attempt to prevent a stall by shifting into
NEUTRAL (N) to ªrev
-upº the engine and regain
forward momentum. This won't work. Your vehicle
will roll backwards very quickly and you could go
out of control.
Instead, apply the regular brake to stop the
vehicle. Then apply the parking brake. Shift to
REVERSE (R), release the parking brake, and
slowly back straight down.

Never attempt to turn around if you are about to
stall when going up a hill. If the hill is steep enough
to stall your vehicle, it's steep enough to cause you
to roll over if you turn around. If you can't make it
up the hill, you must back straight down the hill.
