SCV: Your system has a feature called
Speed
-Compensated Volume (SCV). With SCV,
your audio system adjusts automatically to make up
for road and wind noise as you drive. Set the volume at
the desired level. Turn the control ring behind the upper
knob clockwise to adjust the SCV. Then, as you drive,
SCV 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 SCV, turn the control all the
way down. Each notch on the control ring allows for
more volume compensation at faster vehicle speeds.

cassette tape 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. Be aware that the front seat audio controls
always have priority over the RSA controls. The front
seat passengers switch the source for the main radio to
a remote source, the RSA will play the same remote
source. The rear speakers will be muted when the RSA
power is turned on. You may operate the RSA functions
even when the main radio is off.

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.

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) (or depressing the clutch, if you
have a manual transmission) 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.
Q:Suppose, after stalling, I try to back down
the hill and decide I just can't do it.
What should I do?
A:Set the parking brake, put your transmission
in PARK (P) (or the manual transmission in
FIRST (1)) and turn off the engine. Leave the
vehicle and go get some help. Exit on the uphill
side and stay clear of the path the vehicle would
take if it rolled downhill. Do not shift the transfer
case to NEUTRAL when you leave the vehicle.
Leave it in some gear.

5-14 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 until it first
stops. (Don't press down while turning the
pressure cap.)
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, but now push
down as you turn it. Remove the pressure cap.

Some vehicles may be equipped with a hoist shaft hole
cover on the passenger side of the rear bumper. You
must remove this to gain access to the hoist shaft hole.
Insert your index finger into the indentation near the
lamp and pull to remove the cover.
3. 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.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.
If you have an inside-mounted spare tire, the tire must
be removed in order to have access to the jack storage.
To remove an inside
-mounted spare tire, reach into your
tire's cover and unscrew the wing nut at the center of the
wheel. Remove it and the retainer. Unhook the tire from
the mounting bracket and remove the cover.
To remove a rear
-mounted spare tire, first make sure
that the carrier arm is fully
-latched to the endgate.
Then remove the spare tire cover.
