2004 Pontiac GTO Owner ManualM

Oil Pressure Light
If you have a low engine
oil pressure problem, a
Check Oil message in the
trip computer display
along with this symbol will
stay on after you start
your engine, or come on
when you are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it fixed immediately.
When the ignition is on but the engine is not running,
the light will come on as a test to show you it is working,
but the light will go out when the engine is running. If
it doesn’t come on with the ignition on, you may have a
problem with the bulb. Have it fixed right away.{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.

Change Engine Oil Light
If the Service Engine Oil
message in the trip
computer is displayed
along with this symbol after
you start the engine, it
means that service
is required for your vehicle.
SeeScheduled Maintenance on page 6-4andEngine
Oil on page 5-13for more information.
Security Light
This light flashes when the
vehicle security system is
activated.
Fog Lamp Light

when the fog lamps are
in use.
The light will go out when the fog lamps are turned off.
SeeExterior Lamps on page 3-12for more information.

when the headlamp high
beams are in use.
SeeTurn Signal/Multifunction Lever on page 3-5.

{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned.
The air cleaner not only cleans the air, it helps
to stop ame if the engine backres. If it is
not there and the engine backres, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can
easily get into your engine, which will damage it.
Always have the air cleaner/lter in place when you
are driving.
Automatic Transmission Fluid
When to Check and Change
The fluid level should be checked monthly, by looking at
the fluid level on the dipstick. A good time to check
your automatic transmission fluid level is when
the engine oil is changed.
SeeScheduled Maintenance on page 6-4for more
information on when to check and change the fluid
and filter.
5-19

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. SeeRecommended
Fluids and Lubricants on page 6-13.
Add fluid only after checking the transmission fluid while
it is hot. A cold check is used only as a reference. If
the fluid level is low, add only enough of the proper fluid
to bring the level up to the HOT area for a hot check.
The level should never read over the HOT mark, so be
careful not to add too much. It doesn’t take much
fluid, generally less than 0.6 pints (0.3 L). Don’t overfill.Notice:We recommend you use only uid labeled
DEXRON
®-III, because uid with that label is
made especially for your automatic transmission.
Damage caused by uid other than DEXRON
®-III is
not covered by your new vehicle warranty.
•After adding fluid, recheck the fluid level as
described under “How to Check.”
•When the correct fluid level is obtained, push the
dipstick back in all the way.
Remember to always replace the dipstick and lock
the handle down.
•If fluid has to be added often, there may be a
problem or leak and you should see your vehicle
dealer.
5-22

Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual transmission
doesn’t require changing.
How to Check
Because this operation can be difficult, you may choose
to have this done at your dealership service department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading.
Notice:Too much or too little uid can damage
your transmission. Too much can mean that some
of the uid could come out and fall on hot engine
part or exhaust system parts, starting a re.
Too little uid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission uid.Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the transmission
is cool enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the reverse light switch.
2. Check that the lubricant level is up to the bottom of
the switch hole.
3. If the fluid level is good, install the switch and be
sure it is fully seated. If the fluid level is low, add
more fluid as described in the next steps.
How to Add Fluid
Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
Recommended Fluids and Lubricants on page 6-13.
1. Remove the reverse light switch.
2. Add fluid at the switch hole. Add only enough
fluid to bring the fluid level up to the bottom of
the switch hole.
3. Install the reverse light switch. Be sure the switch is
fully seated.
5-23

Hydraulic Clutch
The clutch fluid level should be checked weekly. A fluid
loss in this system could indicate a problem. If the
clutch fluid requires constant filling up it could indicate a
leak. Have the system inspected and repaired by
your dealer. Adding fluid won’t correct a leak.
When to Check and What to Use
Refer to the Maintenance
Schedule to determine the
proper fluid. SeeOwner
Checks and Services
on page 6-9and
Recommended Fluids and
Lubricants on page 6-13.
How to Check and Add Fluid
To check the fluid level, look at the markings on the
reservoir. If the fluid level is between the MIN and the
MAX line, the fluid level is correct. SeeEngine
Compartment Overview on page 5-12for more
information on location. If the fluid level is between
these marks do not remove the cap, as the fluid
will quickly absorb moisture.
If fluid does need to be added, first turn the vehicle off.
Remove the cap and add the proper fluid. Remember
to replace the cap and clean up any spilled fluid.
5-24

The coolant level should be at or above the COLD FILL
mark. If it isn’t, you may have a leak at the pressure
cap or in the radiator hoses, heater hoses, radiator,
water pump, or somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If
you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive
the vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running. If
the engine is overheating, the fan should be running.
If it isn’t, your vehicle needs service.Notice:If you operate the engine without coolant
or fail to maintain the cooling system properly,
you could damage the engine. The repairs would not
be covered by your warranty. Always follow the
maintenance schedule in this manual for
maintaining your cooling system. SeeCooling
System on page 5-31for more information.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
