If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since your last
oil change. Remember to reset the oil life system
whenever the oil is changed.
After changing the engine oil, reset the system by
performing the following steps:
How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
the engine oil and ®lter based on vehicle use. Anytime
engine oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to the
Service Engine Oil message being turned on, reset
the system.
1. With the engine off, turn the ignition key to ON.
2. Fully press and release the accelerator pedal slowly
two times within ®ve seconds.
3. Turn the key to LOCK.
If the Service Engine Oil message comes back on
when you start your vehicle, the engine oil life
system has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
®lter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of used oil, ask your
dealer, a service station, or a local recycling center
for help.

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.
5-23
2006 - Pontiac GTO Owner Manual

What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOLžcoolant which will not damage
aluminum parts. If this coolant mixture is used, nothing
else needs to be added.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch ®re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
žcoolant.
Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.If coolant needs to be added more than four times a
year, have your dealer check the cooling system.
Notice:If you use extra inhibitors and/or additives
in your vehicle's cooling system, you could
damage your vehicle. Use only the proper mixture
of the engine coolant listed in this manual for
the cooling system. See
Recommended Fluids and
Lubricants on page 6-12for more information.
Checking Coolant
The coolant over¯ow reservoir is located in the engine
compartment on the driver's side of the vehicle. See
Engine Compartment Overview on page 5-12for more
information on location.

If Steam Is Coming From Your Engine
{CAUTION:
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 ®re. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
Notice:If your engine catches ®re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
If No Steam Is Coming From Your
Engine
An overheat warning, along with an Engine Temp Hot
message can indicate a serious problem.
If you get an engine overheat warning, 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.
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,
apply the parking brake, shift to PARK (P) or
NEUTRAL (N) and let the engine idle while you get
out and check that the cooling fan is working.
5-27
2006 - Pontiac GTO Owner Manual

2. If the fan is working and the temperature gage
needle has not returned to its normal position
within a few minutes, stop the engine and remove
the ignition key.
Look for leaks at the radiator hoses and
connections, heater hoses and connections,
radiator, and water pump. Be careful when checking
these areas as they will probably still be hot. If
you ®nd a major leak or other problems that may
have caused the engine to overheat, do not run the
engine until these problems have been corrected.
If you do not ®nd anything wrong, you should check
the engine coolant level. See
Engine Coolant on
page 5-23. You should also check the air intake
area below the front bumper to ensure that it is clear
of leaves and road grime.3. Turn off your air conditioning and turn on your
heater to full hot at the highest fan speed and
open the windows 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 does not come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there is still no sign of steam, you can idle the engine
for three minutes while you are 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.

How to Add Coolant to the Coolant
Over¯ow Reservoir
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch ®re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
žcoolant.If you have not found a problem yet, check the coolant
level on the coolant over¯ow reservoir dipstick. If
the coolant level is not at or above the bottom arrow on
the dipstick, add a 50/50 mixture of clean, drinkable
water and DEX-COOL
žcoolant at the coolant over¯ow
reservoir. SeeEngine Coolant on page 5-23for
more information.
Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.

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.
