hood open PONTIAC GRAND AM 2003 Owners Manual

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. On
the 2.2L L4 ECOTECTM engine, the engine coolant
heater cord is located in front of the coolant
surge tank on the passenger’s side of the engine
compartment. On the 3400
V6 engine, the
engine coolant heater cord is located near the
engine air cleaner/filter. See
Engine Compartment
Overview
on page 5-12 for more information on
location.
3. Plug it into a normal, grounded 1 IO-volt AC outlet.
4. Before starting the engine, be sure to unplug and
store the cord as
it was before to keep it away
from moving engine parts. If you don’t, it could be
damaged.
How long should
you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of
oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give
you the best advice for that
particular area.
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a fire. You could be seriouslv
injured. Plug the cord into a properly grounded
three-prong
1 IO-volt AC outlet. If the cord
won’t reach, use a heavy-duty three-prong
extension cord rated for at least
15 amps.

California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed
to operate on fuels that meet California
specifications.
If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may
turn on (see
Malfunction lndicator Lamp on page 3-31)
and your vehicle may fail a smog-check test. If this
occurs, return to your authorized GM dealer for
diagnosis.
If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work
properly. You should not have to add anything to your
fuel. Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines may be
available in your area
to contribute to clean air. General Motors
recommends that you use these
gasolines, particularly
if they comply with the
specifications described earlier.
Nofice: Your vehicle was not designed for fuel that
contains methanol. Don’t use fuel containing
methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage wouldn’t be covered under your
warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors does
not recommend the use of such gasolines. Fuels
containing MMT can reduce the life of spark plugs and
the performance of the emission control system may
be affected. The malfunction indicator lamp may turn on.
If this occurs, return to your authorized GM dealer for
service.

Checking Things Under
the Hood
Hood Release
To open the hood, do the following:
1. Pull the handle located
under the instrument
panel on the drivier's side
of the vehicle.
L% CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not running. Keep hands, clothing and tools away
from any underhood electric fan.
Things that burn can get on hot engine parts
and start
a fire. These include liquids like fuel,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.

If Steam Is Coming From Your Engine
Steam from an overheated engine can burn
you badly, even
if you just open the hood. Stay
away from the engine
if you see or hear steam
coming from
it. Just turn it off and get
everyone away from the vehicle until
it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You
or others could be badly burned. Stop your
engine if
it overheats, and get out of the
vehicle until the engine is cool.
Nofice: If your engine catches fire because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
5-27

If No Steam Is Coming From Your
Engine
An overheat warning, along with a low coolant light, can indicate a serious problem. See
Low Coolant Warning
Light on page
3-30.
If you get an engine overheat warning with no low
coolant light, but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a
little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. If
you get the overheat warning with no sign
of steam,
try this for a minute or
so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK
(P) or NEUTRAL (N) and let the
engine idle.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for three minutes while you’re parked. If you still
have the warning,
turn off the engine and get everyone
out
of the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.

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.
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
transaxle in PARK (P) or a manual transaxle 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. 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
Engine Compartment Overview
on page
5-12 for more information on location.

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.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly.
Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield.
Also see
Cleaning the Outside of Your Vehicle on page 5-75.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better,' and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be required. See
Part D: Recommended Fluids and
Lubricants on page
6- 15.
Manual Transaxle Check
It is not necessary to check the transaxle fluid level.
Check for leaks. A fluid leak is the only reason for fluid
loss. Have the system inspected and repaired if
needed.
Automatic Transaxle Check
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss.
Check for leaks. If a leak occurs, take the vehicle to your
dealer and have
it repaired as soon as possible.
Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
Hydraulic Clutch on page 5-23. A fluid loss in this
system could indicate a problem. Have the system
inspected and repaired at once.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part
D.
Body Lubrication Service
Lubricate all the door hinges and latches, including
those for the hood and the trunk lid. Part D tells
you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.
