Battery Voltage Low
This symbol appears
with the Battery Voltage
Low message.
This message will appear when the electrical system
is charging less than 10 volts or if the battery has
been drained.
If this message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may take
a few hours to do so. Consider using an auxiliary
charger (be sure to follow the manufacturer's
instructions) to boost the battery after returning home or
to a final destination.
If this message appears while driving or after starting
your vehicle and stays on, have it checked immediately
to determine the cause of this problem.
To help the generator recharge the battery quickly, you
can reduce the load on the electrical system by turning
off the accessories.The normal battery voltage range is 11.5 to 15.5 volts.
You can monitor battery voltage on the DIC by pressing
the INFO button until you find BATTERY VOLTS
(base audio system) or by selecting Battery Voltage
from the Vehicle Info menu (Navigation system).
Change Engine Oil
This symbol appears
with the Change Engine
Oil message.
This message indicates that the life of the engine oil has
expired and it should be changed within 200 miles. See
ªEngine Oilº in the Index for more information.
When you reset the Change Engine Oil message by
clearing it from the display, you still must reset the
engine oil life monitor separately. For more information
on resetting the engine oil life monitor, see ªOil Life
Monitor, How to Resetº in the Index.

Setting Preset Stations
The six numbered pushbuttons (F1 through F6) let
you return to your favorite stations. You can set up to
18 stations (six AM, six FM1 and six FM2). You can
set your preset stations manually or automatically and
presets for home and away.
To set your preset stations manually, perform the
following steps:
1. Turn the radio on.
2. Press BAND to select AM, FM1 or FM2.
3. Tune in the desired station.
4. Press and hold one of the six numbered pushbuttons
for two seconds until you hear a beep. The set preset
station number will appear on the display above the
pushbutton that it is set to. Whenever you press that
numbered pushbutton for less than two seconds, the
station you set will return.
5. Repeat the steps for each pushbutton.
To set your preset stations with an equalization
setting, DSP setting, or a PTY setting, see each of
these features later in this section. When a preset
station is selected, once one of these additional
settings is selected, the preset station will remember
each setting and it will remain active, until the
setting is selected off for that preset station.AUTOSTORE PRESETS: To set your preset stations
automatically, perform the following steps:
1. Turn the radio on.
2. Press BAND to select AM, FM1 or FM2.
3. Press the TUNE/SEL knob to enter the main menu.
4. Turn the TUNE/SEL knob until AUTOSTORE
PRESETS appears on the display.
5. Press the TUNE/SEL knob again to select.
AUTOSTORE will appear on the display. The radio
will automatically search the band and select and
store the six radio stations with the strongest signal.
The stations will be stored by signal strength, not
sequential order. The set preset station number will
appear on the display above the pushbutton that it is
set to. Whenever you press that numbered
pushbutton for less than two seconds, the station that
is set will return.
6. Press the BACK button to exit the display. To return
to the original display repeatedly press the BACK
button or wait for the display to time out.
When battery power is removed and later applied, you
will not have to reset your radio presets because they
remain in the radios memory.

3-29 Understanding Radio Reception
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.
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.Cellular Phone Usage
Cellular phone usage may cause interference with your
vehicle's radio. This interference may occur when
making or receiving phone calls, charging the phone's
battery or simply having the phone ªonº. This
interference is described as an increased level of static
while listening to the radio. If you notice static while
listening to the radio, unplug the cellular phone and
turn if off.

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road about 300 feet (100 m) behind
your vehicle.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to follow the steps below to do it safely.
CAUTION:
Batteries can hurt you. They can be dangerous
because:

They contain acid that can burn you.

They contain gas that can explode or ignite.

They contain enough electricity to
burn you.
If you don't follow these steps exactly, some or all
of these things can hurt you.
NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn't be covered by your
warranty.
The ACDelco battery in your vehicle has a
built
-in hydrometer. Do not charge, test or jump
start the battery if the hydrometer looks clear or
light yellow. Replace the battery when there is a
clear or light yellow hydrometer and a cranking
complaint.
Trying to start your vehicle by pushing or pulling
it won't work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
NOTICE:
If the other system isn't a 12-volt system with a
negative ground, both vehicles can be damaged.

5-4
2. Get the vehicles close enough so the jumper cables
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 vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlets. Turn off the
radio and all lamps that aren't needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (
-) terminal locations on
each vehicle. See ªEngine Compartment Overviewº
in the Index for more information on location of
the battery.

5-5
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.
CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You don't
need to add water to the ACDelco
battery
installed in your new vehicle. But if a battery has
filler caps, be sure the right amount of fluid is
there. If it is low, add water to take care of that
first. If you don't, explosive gas could be present.
Battery fluid contains acid that can burn you.
Don't get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

5-6
CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables don't have loose or
missing insulation. If they do, you could get a shock.
The vehicles could also be damaged, too.
Before you connect the cables, here are some basic
things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if the
vehicle has one. Negative (
-) will go to a heavy,
unpainted metal engine part or to a remote
negative (
-) terminal if the vehicle has one.
Don't connect positive (+) to the negative (
-) or you
will get a short that would damage the battery and
maybe other parts, too. And don't connect the
negative (
-) cable to negative (-) terminal on the
dead battery because this can cause sparks.
6. Connect the red positive (+) cable to the positive (+)
terminal of the dead battery. Use a remote
positive (+) terminal if the vehicle has one.

5-7
7. Don't let the other end
touch metal. Connect it
to the positive (+)
terminal of the good
battery. Use a remote
positive (+) terminal if
the vehicle has one.
8. Now connect the
black negative (
-)
cable to the
negative terminal
of the good battery.
Use a remote
negative (
-)
terminal if the
vehicle has one.Don't let the other end touch anything until the next
step. The other end of the negative (
-) cable doesn't
go to the dead battery. It goes to a heavy, unpainted
metal engine part or to a remote negative (
-) terminal
on the vehicle with the dead battery.
9. Connect the
other end of the
negative (
-) cable
at least 18 inches
(45 cm) away from
the dead battery,
but not near engine
parts that move.
The electrical connection is just as good there, and
the chance of sparks getting back to the battery is
much less.

5-8
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that has the dead battery.
If it won't start after a few tries, it probably
needs service.
NOTICE:
Damage to your vehicle may result from
electrical shorting if jumper cables are removed
incorrectly. To prevent electrical shorting, take
care that the cables don't touch each other or any
other metal period. The repairs wouldn't be
covered by your warranty.
