To remove the fuel cap, turn it slowly counterclockwise.
The fuel cap has a spring in it; if the cap is released
too soon, it will spring back to the right.
{CAUTION:
If you spill fuel and then something ignites it,
you could be badly burned. Fuel can spray out
on you if you open the fuel cap too quickly.
This spray can happen if your tank is nearly
full, and is more likely in hot weather. Open
the fuel cap slowly and wait for any hiss noise
to stop. Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or over®ll the
tank and wait a few seconds after you have ®nished
pumping before removing the nozzle. Clean fuel
from painted surfaces as soon as possible. See
Washing Your Vehicle on page 5-80.When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. This would allow fuel
to evaporate into the atmosphere. See
Malfunction
Indicator Lamp on page 3-28.
{CAUTION:
If a ®re starts while you are refueling, do not
remove the nozzle. Shut off the ¯ow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not ®t properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. See
Malfunction Indicator Lamp on
page 3-28.

The level should never read over the HOT mark, so be
careful not to add too much. It does not take much
¯uid, generally less than 0.6 pints (0.3 L). Do not over®ll.
Notice:Use of the incorrect automatic transmission
¯uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transmission ¯uid listed in
Recommended Fluids and Lubricants on page 6-12.
·After adding ¯uid, recheck the ¯uid level as
described under ªHow to Check Automatic
Transmission Fluid,º earlier in this section.
·When the correct ¯uid level is obtained, push the
dipstick back in all the way.
Remember to always replace the dipstick and lock
the handle down.
·If ¯uid has to be added often, there may be a
problem or leak and you should see your dealer.
Manual Transmission Fluid
When to Check Manual Transmission
Fluid
A good time to have your manual transmission ¯uid
checked is when the engine oil is changed. However,
the ¯uid in your manual transmission does not
require changing.
How to Check Manual Transmission
Fluid
Because this operation can be difficult, you may choose
to have this done at the 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 ¯uid 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 ®ngers 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 ¯uid level is good, install the switch and be
sure it is fully seated. If the ¯uid level is low, add
more ¯uid as described in the next steps.

2006 - Pontiac GTO Owner Manual

How to Add Manual Transmission Fluid
Here is how to add ¯uid. Refer to the Maintenance
Schedule to determine what kind of ¯uid to use. See
Recommended Fluids and Lubricants on page 6-12.
1. Remove the reverse light switch.
2. Add ¯uid at the switch hole. Add only enough
¯uid to bring the ¯uid level up to the bottom of
the switch hole.
3. Install the reverse light switch. Be sure the switch is
fully seated.
Hydraulic Clutch
The clutch ¯uid level should be checked weekly. A ¯uid
loss in this system could indicate a problem. If the
clutch ¯uid requires constant ®lling it could indicate a
leak. Have the system inspected and repaired by
your dealer. Adding ¯uid will not correct a leak.
When to Check and What to Use
Refer to the Maintenance
Schedule to determine the
proper ¯uid. See
Owner
Checks and Services
on page 6-8
andRecommended Fluids and
Lubricants on page 6-12.

How to Check and Add Fluid
To check the ¯uid level, look at the markings on the
reservoir. If the ¯uid level is between the MIN and the
MAX line, the ¯uid level is correct. If the ¯uid level
is between these marks do not remove the cap, as the
¯uid will quickly absorb moisture. See
Engine
Compartment Overview on page 5-12for more
information on reservoir location.
If ¯uid does need to be added, ®rst turn the vehicle off.
Remove the cap and add the proper ¯uid. Remember
to replace the cap and clean up any spilled ¯uid.
Engine Coolant
The cooling system in your vehicle is ®lled with
DEX-COOLžengine coolant. This coolant is designed
to remain in the vehicle for ®ve years or 150,000 miles
(240 000 km), whichever occurs ®rst, if only
DEX-COOL
žextended life coolant is added.The following explains the cooling system and how to
add coolant when it is low. If there is a problem
with engine overheating or if coolant needs to be added
to the radiator, see
Engine Overheating on page 5-26.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC).
·Give boiling protection up to 265ÉF (129ÉC).
·Protect against rust and corrosion.
·Help keep the proper engine temperature.
·Let the warning lights and gages work as
they should.
Notice:Using coolant other than DEX-COOLžmay
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the ®rst maintenance
service after each 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
ž(silicate-free) coolant in your vehicle.

Brakes
Brake Fluid
Your brake master cylinder
reservoir is ®lled with
DOT-4 brake ¯uid. See
Engine Compartment
Overview on page 5-12for
the location of the
reservoir.
There are only two reasons why the brake ¯uid level in
the reservoir might go down. The ®rst is that the
brake ¯uid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the ¯uid level goes back up. The other reason is
that ¯uid is leaking out of the brake system. If it is, you
should have your brake system ®xed, since a leak
means that sooner or later your brakes will not work
well, or will not work at all.
So, it is not a good idea to top off your brake ¯uid.
Adding brake ¯uid will not correct a leak. If you add ¯uid
when your linings are worn, then you will have too
much ¯uid when you get new brake linings. You should
add or remove brake ¯uid, as necessary, only when
work is done on the brake hydraulic system.
{CAUTION:
If you have too much brake ¯uid, it can spill on
the engine. The ¯uid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
¯uid only when work is done on the brake
hydraulic system. See ªChecking Brake Fluidº
in this section.
When your brake ¯uid falls to a low level, your brake
warning light will come on. See
Brake System Warning
Light on page 3-27.
Checking Brake Fluid
You can check the brake ¯uid without taking off the cap.
Look at the brake ¯uid reservoir. The ¯uid level should
be between the MIN and MAX marks on the reservoir. If
it is not, have your brake system checked to see if
there is a leak.
After work is done on the brake hydraulic system, make
sure the level is between the MIN and MAX marks.

2006 - Pontiac GTO Owner Manual

What to Add
When you do need brake ¯uid, use only DOT-4 brake
¯uid. Use new brake ¯uid from a sealed container
only. See
Recommended Fluids and Lubricants on
page 6-12.
Always clean the brake ¯uid reservoir cap and the area
around the cap before removing it. This will help
keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of ¯uid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake ¯uid.
Notice:
·Using the wrong ¯uid can badly damage brake
system parts. For example, just a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system parts so
badly that they will have to be replaced. Do not
let someone put in the wrong kind of ¯uid.
·If you spill brake ¯uid on your vehicle's painted
surfaces, the paint ®nish can be damaged. Be
careful not to spill brake ¯uid on your vehicle. If
you do, wash it off immediately. See
Washing
Your Vehicle on page 5-80.
Brake Wear
Your vehicle has four-wheel disc brakes.
Some driving conditions or climates may cause a brake
squeal when the brakes are ®rst applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to GM torque speci®cations.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.

Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn off the radio and all lamps that are
not needed. This will avoid sparks and help save
both batteries. And it could save the 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 5-12for more information on location.
{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 battery 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 don't, 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.

Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment
However, if the vehicle is damaged in an accident, the
headlamp aim may be affected and adjustment may
be necessary.
If oncoming vehicles ¯ash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be re-aimed.
It is possible however, to re-aim the headlamps as
described in the following procedure.
The vehicle should be properly prepared as follows:
·The vehicle should be placed so the headlamps
are 15 ft. (4.6 m) from a light colored wall or
other ¯at surface.
·The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other ¯at surface.
·The vehicle should be placed so it is perpendicular
to the wall or other ¯at surface.
·The vehicle should not have any snow, ice, or mud
on it.
·The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being
performed.
·The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs (75 kg)
sitting on the driver's seat.
·Tires should be properly in¯ated.
·The spare tire is in its original location in
the vehicle.
Headlamp aiming is done with the vehicle's low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
5-43
2006 - Pontiac GTO Owner Manual

To adjust the vertical aim on the headlamps, do the
following:
1. Open the hood. See
Hood Release on page 5-11for more information.
2. Find the aim dot on the lens of the low-beam
headlamp.
3. Measure the distance from the ground to the aim
dot on the low-beam headlamp. Record the
distance.
4. At the wall or other ¯at surface, measure from the
ground upward the recorded distance from Step 2
and mark it.
5. Draw or tape a horizontal line the width of the
vehicle at the wall or other ¯at surface where it
was marked it Step 4.
Notice:Do not cover a headlamp to improve beam
cut-off when aiming. Covering a headlamp may
cause excessive heat build-up which may cause
damage to the headlamp.
6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being aimed. This should allow only
the beam of light from the headlamp being
aimed to be seen on the ¯at surface.
7. Locate the vertical headlamp aiming screws, which
are under the hood near each headlamp assembly.
The adjustment screw can be turned with a
No. 2 Phillips head screwdriver.
