Running Your Engine While You’re
Parked (Automatic Transmission)
It’s better not to park with the engine running. But if
ever have to, here are some things to know.
Idling the engine with the air system control
off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust
-- with
CO -- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be
a blizzard.
l (See “Blizzard” in the Index.)
I-
It can be dangerous to get out of your vehicle if
the shift lever is not fully in
PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is running unless you have to.
If you’ve left the
engine running, the vehicle can move suddenly.
You or others could be injured.
To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to
PARK (P).
If you have four-wheel drive with a manual transfer case
shift lever and your transfer case is in NEUTRAL
(N),
your vehicle will be free to roll, even if your shift lever
is in
PARK (P). So, be sure the transfer case is in a drive
gear
-- not in NEUTRAL (N). Always set your parking
brake. Follow the proper steps
to be sure your vehicle
won’t move. See “Shifting Into
PARK (P)” in the Index.
If you’re pulling a trailer, see “Towing a Trailer” in
the Index.

Programming the Transmitter
Do not LIS~ the transmitter with any garage door opener
that does not have the ”stop and reverse’‘ feature. This
includes any garage door opener model manufactured
before April
1, 1982.

Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program
up to three channels:
I, If you have not previously programmed a universal
channel, proceed to Step
2. Otherwise, hold down the
two outside buttons on the universal transmitter
until
the red light begins to flash rapidly (approximately
20 seconds). Then rekase the buttons. This procedure
initializes the memory and erases any previous
settings for all three channels.
2. Hold the end of the hand-held transmitter against the
bottom surface of the ~~niversal transmitter
so that
you can still see the red
light.
3. Decide which one of the three channels you want to
program. Using both hands, press the hand-held
transmitter button and the desired button on the
universal transmitter. Continue
to hold both buttons
through Step
4.
4.
Hold down both buttons until yo~r see the red light
on the Llniversal transmitter flash rapidly. The rapid
flashing, which could take up
to 90 seconds,
indicates that the universal transmitter has been
programmed. Release both buttons once the light
starts
to flash rapidly.
If you have trouble programming the universal
transmitter, make s~rre that you have followed the
directions exactly
as described and that the battery in the
hand-held transmitter is not dead.
If yo~t still cannot
program
it, rotate the hand-held transmitter end over end
and
try again. The universal transmitter may not work
with older garage door openers that do not meet current
Federal Consumer Safety Standards.
If you cannot
program the transmitter after repeated attempts. consult
your
GM dealer.
Be sure to keep the original hand-held transmitter in case
you need
to erase and reprogram the universal transmitter.

Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (kndh).
Your odometer shows how far your vehicle has been
driven,
in either miles (used in the United States) or
kilometers (used
in Canada).
Your odometer is tamper resistant.
It will show silver lines
between the numbers
if someone tries to turn it back.
You may wonder what happens
if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then
it must be. But if
it can't, then it's set at zero, and a label must be put on
the driver's door to show the old mileage reading when
the new odometer was installed.
Trip Odomet
The trip odometer can tell you how fir your vehicle has
been driwn since you last set the
trip odometer to zero.
To set the trip odome.ter to zero, press the button near
the readout.
Tachometer (If Equipped)
The tachometer displays the engine speed in revolutions
ner minute (rprn). Each
tachometer has
a different limit depending on the
powertrain
in your vehicle. The tachometer has three
areas: normal operating range, red warning range and
red danger range.
The normal operating range shows your engine speed
during normal driving conditions.
For example, when
the needle points
to 2, it means the engine is running at
2.000 revolutions per minute (rpm). The tachometer
needle
will vary all the time that the engine is running.
The shaded red warning range tells you that your engine
speed
is reaching its upper limits. Don't drive very long
with the tachometer
in the red warning range. If you
have
a manual transmission. shift to a higher gear as
soon as possible. If you have an automatic transmission,
lift your foot off of the accelerator pedal.
The solid red danger range tells you that your engine speed
is at its upper limits. Your should immediately shift
to a
higher gear, or lift your foot off of the accelerator pedal.
1 NOTICE:
Do not operate the engine with the tachometer in
the red range,
or engine damage will occur.

Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures
will help you
locate them.
Warning lights and gages can signal that something
is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention
to
your warning lights and gages could also save you or
others from
injury.
Warning lights come on wl1e.n there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to
let you know they’re working. If you are
familiar with
this section, you should not be alarmed
when this happens.
Gages can indicate when there may
be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to
let you know when
there’s
a problem with your vehicle. When one
of the warning lights comes on and stays
on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about
it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re
a big help.
Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for about eight seconds to remind people to
fisten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light
will
also come on and stay on
for about
20 seconds,
then
it will flash for about
55 seconds. If the driver’s
belt is already buckled,
neither the tone nor the
light
will come on.

Air Bag Readiness Light
There is an air bag readiness light 011 the instrument
panel, which shows
AIR RAG. The system checks the
air bag's electrical system for ~~~alfunctions. The light
tells you if there is an electrical problem. The syslem
check includes the air bag sensors. the air
bag module,
the wiring and the diagnostic module. For n~ore
information
on the air bag system. sec .'Air Rag" in
the Index.
AIR
BAG
This light will ~0111e on
when you start your engine,
and it will flash for a few
seconds. Then thc light
should go out. This means
the system
is ready.
If the air bag readiness light stays 011 after you start the
engine or comes on when you are driving, your ail- bag
system
may not work properly. Have your vehicle
serviced right
away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to
RUN. If the
light doesn't
co111e on then. have it fixed so it will be
re.ady
to warn you if there is a problem.

lrging System Indicator Light
II
The charging system light
will come on brietly when
you turn on the ignition,
but the engine is not
running, as
a check to
show you it is working.
It should go out once the engine is running. If it stays
on. or comes on while you are driving. you may have
a problem with the. charging system. It could indicate
that
you have problem with a generator drive belt. or
another electrical problem. Have it checked right away.
Driving while this light
is on could drain your battery.
If you must drive a short distance with the light 011, be
certain to turn off
all your accessories. such as the radio
and air conditioner.

Voltmeter Gage
When your engine is not
running. but the ignition is
on (in the RUN position).
this gage shows
your
battery’s state of charge in
DC volts.
VOLTS
When the engine is running, the gage shows the
condition
of the. charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the
low warning mne may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since
the
charging system is not able to provide full power at
engine idle. As engine speeds are increased, this
condition should correct itself
as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings
in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced
as soon as possible.
