Understanding Radio Reception
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing
the sound to come and go.
AM
The range for most AM stations is greater than for FM,
especially
at night. The longer range, however, can
cause stations to interfere with each other.
AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until
it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to
a safe
sound level before your hearing adapts to it.

Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know
is this: let your engine do some of the
slowing down. Shift to a lower gear when you
go
down a steep or long hill.
A CAUTION:
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going down
a hill. You could crash. Shift down to let your
engine assist your brakes on a steep
downhill slope.

Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They could get
so hot that they wouldn’t work well. You would
then have
poor braking or even none going down
a hill. You could crash. Always have your engine
running and your vehicle
in gear when you
go downhill.
Know how to go uphill. You may want to shift down
to a lower gear.
The lower gears help cool your engine
and transmission, and you can climb
the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn
of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area
or winding
roads. Be alert to these and
take appropriate action.

can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your Corvette, and the bad grounding could

unnecessary accessories plugged into the cigarette

Turn off all lamps that
aren’t needed as well as radios. This will avoid
sparks and help save both batteries. In addition, it
could save your radio!

NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries. Find the
positive

A CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood electric fan.

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Corvette
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered
by your
warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Corvette,
see “Servicing
Your Air Bag-Equipped Corvette” in the Index.
Accessory Power Plug
This plug can be used to connect electrical equipment
such as a cellular phone or CB radio. The accessory
power plug is located at the top left corner
of the
passenger’s side footwell. Be sure to follow the
installation instructions included with the equipment.
To use the accessory power plug:
1. Remove the toe-board panel by lifting up on the
latches at the top
of each corner of the panel.
2. Locate the black connector at the left top corner of
the compartment near the body control module
above the two white diagnostic connectors.
3. Disconnect the connector pigtail by pulling forward
on the plastic locking tab and pull the connection
apart from the wire harness.
The plug has three separate wires:
The orange wire connects to battery power.

A CAUTION:
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there
is room in front of your vehicle in case
it begins to roll. Be ready to apply the regular
brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.
To check the parking brake’s holding ability:
With the engine running and transmission in
NEUTRAL
(N), slowly remove foot pressure from
the regular brake pedal.
Do this until the vehicle is
held by the parking brake only.
To check the PARK (P) mechanism’s holding ability:
With the engine running, shift to PARK (P). Then
release all brakes.
Underbody Flushing Service
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.
