display, the tape won't play because of one of the
following errors.

The tape is tight and the player can't turn the tape
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
and repeat. If the hubs do not turn easily, your tape
may be damaged and should not be used in the
player. Try a new tape to make sure your player is
working properly.

The tape is broken. Try a new tape.

The tape is wrapped around the tape head. Attempt
to get the cassette out. Try a new tape.(CLEAN): If this message appears on the display, the

VOLUME PWR: Press this control to turn the system
on and off. To increase volume, turn the control
clockwise. Turn it counterclockwise to decrease volume.
AUTO VOL: Your system has a feature called
automatic volume. With this feature, your audio system
adjusts automatically to make up for road and wind
noise as you drive. Set the volume at the desired level.
Press this button to select MIN, MED, MAX or OFF.
Each choice allows for more volume compensation at
faster vehicle speeds. Then, as you drive, automatic
volume automatically increases the volume, as
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.
If your vehicle has the Bose radio, your audio system
monitors the noise inside your vehicle. Then,
automatically adjusts the volume so that it always
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.
VOL: Turn the knob clockwise to increase volume and
counterclockwise to decrease volume. The left VOL
knob controls the left headphone and the right VOL
knob controls the right headphone.
PROG: With a cassette tape in the player and the radio
playing, press this button to play a cassette tape. Press
PROG to switch between the tape and compact disc if
both are loaded. Press PROG again to return to the radio
when a cassette tape or compact disc is playing. The
inactive tape or CD will remain safely inside the radio
for future listening.
SEEK: Press the SEEK button to tune to the next
station and stay there. The display will show your
selection. The sound will mute while seeking.
Press and hold the SEEK button to seek through
your preset radio stations set on your primary radio
pushbuttons. The display will show your selections.

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.

5-15 How to Add Coolant to the Radiator
1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about one full turn.
If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure left.
2. Then keep turning the pressure cap. Remove the
pressure cap.

2. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench
until the spare tire can be pulled out from under
the vehicle.
If the spare tire does not lower to the ground,
the secondary latch is engaged causing the tire not
to lower. See ªSecondary Latch Systemº later in
this section.
When the tire has been completely lowered, tilt the
retainer at the end of the cable and pull it through
the wheel opening. Pull the tire out from under
the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before the cable is properly stored.
3. Put the spare tire near the flat tire.
4. Use the chisel end of the wheel wrench to pry off
the center cap.
See ªRemoving the Flat Tire and Installing the
Spare Tireº later in this section to continue changing
the flat tire.
