CAUTION: (Continued)
·
Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the air¯ow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane
of 87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or higher as
soon as possible. Otherwise, you might damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary. If you are using 87 octane or higher-octane
fuel and hear heavy knocking, your engine needs
service.

Engine Oil
If the low engine oil level message appears on the
instrument cluster, it means you need to check your
engine oil level right away. For more information,
see
Low Engine Oil Level Message on page 3-53.
You should check your engine oil level regularly; this is
an added reminder.United States

The terminal is located
under a tethered cap at
the front of the underhood
fuse block. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
Squeeze the tabs and pull up on the cap to access
the remote positive (+) terminal. You should
always use the remote positive (+) terminal instead
of the positive (+) terminal on your battery.
{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
¯ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the ACDelco
žbattery
installed in your new vehicle. But if a battery
has ®ller caps, be sure the right amount of
¯uid is there. If it is low, add water to take care
of that ®rst. If you do not, explosive gas could
be present.
Battery ¯uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ¯ush the place
with water and get medical help immediately.

If the accessory in¯ator system does not turn on or the
light does not come on, the fuse may be blown or
installed incorrectly. See
Fuses and Circuit Breakers on
page 5-96or see your dealer for service.
Your accessory in¯ator will automatically shut off after
about 10 minutes. The light in the switch will blink. After
about one minute you can use the system again.
Press the switch and the indicator light will come on.
Notice:If you run the accessory in¯ator longer than
30 minutes at a time, you could damage the
in¯ator. The repairs would not be covered by your
warranty. Run the in¯ator for short periods of
time only.After running the accessory in¯ator for 30 minutes, wait
at least 10 minutes before restarting the accessory
in¯ator.
To turn off the in¯ator, do the following:
1. Press the switch and detach the hose, ®rst from the
in¯ated object, then from the outlet.
2. Put the protective cap back on.
3. Place the in¯ator kit tools in the pouch, and store in
the glove box.
To put the cap back on, line up the tabs at the back of
the cover and put it in place. Push down the tab to
secure the cap.

Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your vehicle
unless you check with your dealer ®rst. 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 vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-102.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, be sure to get it ®xed.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel fuse panel
protect the power windows and other power accessories.
When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the
problem is ®xed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don't have
a spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the
underhood fuse block. Just pick some feature of your
vehicle that you can get along without ± like the radio or
cigarette lighter ± and use its fuse, if it is the right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle, the instrument
panel fuse block and the underhood fuse block.
