Caution
Do not add too much oil. Oil levels above
or below the acceptable operating range
shown on the dipstick are harmful to the
engine. If the oil level is above the
operating range (i.e., the engine has so
much oil that the oil level gets above the
cross-hatched area that shows the proper
operating range), the engine could be
damaged. Drain the excess oil or limit
driving of the vehicle, and seek a service
professional to remove the excess oil.
See Engine Compartment Overview 0231 for
the location of the engine oil fill cap.
Add enough oil to put the level somewhere
in the proper operating range. Push the
dipstick all the way back in when through.
Selecting the Right Engine Oil (2.0L (LTG)
L4 and 3.6L (LGX) V6 Engines)
Selecting the right engine oil depends on
both the proper oil specification and
viscosity grade. See Recommended Fluids
and Lubricants 0304. Specification
Use full synthetic engine oils that meet the
dexos1 specification. Engine oils that have
been approved by GM as meeting the
dexos1 specification are marked with the
dexos1 approved logo. See
www.gmdexos.com.
Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.
Viscosity Grade
Use SAE 5W-30 viscosity grade engine oil.
Cold Temperature Operation: In an area of
extreme cold, where the temperature falls
below −29 °C (−20 °F), an SAE 0W-30 oil may
be used. An oil of this viscosity grade will
provide easier cold starting for the engine at
extremely low temperatures. For the LT1 engine only, if 0W-40 dexosR oil
is not available, SAE 5W-30 dexos1 full
synthetic engine oil may be used for
street use.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification”
earlier in this section.
Selecting the Right Engine Oil (6.2L (LT1)
V8 Engine)
Selecting the right engine oil depends on
both the proper oil specification and
viscosity grade. See Recommended Fluids
and Lubricants 0304.
Specification
Use engine oils that meet the dexosR
specification. Engine oils that have been
approved by GM as meeting the dexosR
specification are marked with the dexosR
approved logo. See www.gmdexos.com.

Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.
Viscosity Grade
Use SAE 0W-40 viscosity grade engine oil.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification” earlier in this section.
If 0W-40 dexosR oil is not available, SAE
5W-30 dexosR full synthetic engine oil may
be used for street use.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the dexos
specification are all that is needed for good
performance and engine protection.
Engine oil system flushes are not
recommended and could cause engine
damage not covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains certain elements
that can 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 filter before disposal.
Never dispose of oil by putting it in the
trash or pouring it on the ground, into
sewers, or into streams or bodies of water.
Recycle it by taking it to a place that
collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that
indicates when to change the engine oil and
filter. This is based on a combination of
factors which include engine revolutions,
engine temperature, and miles driven. Based
on driving conditions, the mileage at which
an oil change is indicated can vary considerably. For the oil life system to work
properly, the system must be reset every
time the oil is changed.
When the system has calculated that oil life
has been diminished, it indicates that an oil
change is necessary. A CHANGE ENGINE OIL
SOON message comes on. Change the oil as
soon as possible within the next 1 000 km
(600 mi). It is possible that, if driving under
the best conditions, the oil life system
might indicate that an oil change is not
necessary for up to a year. The engine oil
and filter must be changed at least once a
year and, at this time, the system must be
reset. Your dealer has trained service people
who will perform this work and reset the
system. It is also important to check the oil
regularly over the course of an oil drain
interval and keep it at the proper level.
If the system is ever reset accidentally, the
oil must be changed at 5 000 km (3,000 mi)
since the last oil change. Remember to reset
the oil life system whenever the oil is
changed.

comes back on when the vehicle is started,
the engine oil life system has not been
reset. Repeat the procedure.
Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission
fluid level. A transmission fluid leak is the
only reason for fluid loss. If a leak occurs,
take the vehicle to your dealer and have it
repaired as soon as possible.
The vehicle is not equipped with a
transmission fluid level dipstick. There is a
special procedure for checking and changing
the transmission fluid. Because this
procedure is difficult, this should be done at
the dealer. Contact the dealer for additional
information or the procedure can be found
in the service manual. To purchase a service
manual, see Publication Ordering
Information 0321.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty. Always
use the correct automatic transmission
fluid. See Recommended Fluids and
Lubricants 0304. Change the fluid and filter at the intervals
listed in
Maintenance Schedule 0300, and
be sure to use the fluid listed in
Recommended Fluids and Lubricants 0304.
Manual Transmission Fluid
It is not necessary to check the manual
transmission fluid level. A transmission fluid
leak is the only reason for fluid loss. If a
leak occurs, take the vehicle to your dealer
and have it repaired as soon as possible. See
Recommended Fluids and Lubricants 0304
for the proper fluid to use.
Hydraulic Clutch
For vehicles with a manual transmission, it
is not necessary to regularly check brake/
clutch fluid unless there is a leak suspected.
Adding fluid will not correct a leak. A fluid
loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use

Vehicle Care 239
The brake/hydraulic clutch fluid reservoir cap
has this symbol on it. SeeEngine
Compartment Overview 0231 for reservoir
location. The common hydraulic clutch and
brake master cylinder fluid reservoir is filled
with brake fluid as indicated on the reservoir
cap. See Brake Fluid 0248 for brake fluid
to use.
How to Check and Add Fluid
Visually check the brake/clutch fluid
reservoir to make sure the fluid level is at
the MIN (minimum) line on the side of the
reservoir. The brake/hydraulic clutch fluid
system should be closed and sealed.
Do not remove the cap to check the fluid
level or to top-off the fluid level. Remove
the cap only when necessary to add the
proper fluid until the level reaches the
MIN line.
Engine Air Filter Life System (2.0L
LTG and 3.6L LGX Engines Only)
If equipped, this feature provides the engine
air filter’s remaining life and best timing for
a change. The timing to change an engine
air filter depends on driving and
environmental conditions.
When to Change the Engine Air Filter
When the Driver Information Center (DIC)
displays a message to replace the engine air
filter at the next oil change, follow this
timing.
When the DIC displays a message to replace
the engine air filter soon, replace the engine
air filter at the earliest convenience.
The system must be reset after the engine
air filter is changed.
If the DIC displays a message to check the
engine air filter system, see your dealer.

{Warning
An underhood electric fan can start up
even when the engine is not running and
can cause injury. Keep hands, clothing,
and tools away from any underhood
electric fan.
{Warning
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The cooling system in the vehicle is filled
with DEX-COOL engine coolant. See
Maintenance Schedule 0300 and
Recommended Fluids and Lubricants 0304.
The following explains the cooling system
and how to check and add coolant when it
is low. If there is a problem with engine
overheating, see Engine Overheating 0245.
What to Use
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get

Warning (Continued)
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
Use a 50/50 mixture of clean drinkable
water and DEX-COOL coolant. This mixture:
.Gives freezing protection down to −37 °C
(−34 °F), outside temperature
.Gives boiling protection up to 129 °C
(265 °F), engine temperature
.Protects against rust and corrosion
.Will not damage aluminum parts
.Helps keep the proper engine
temperature
Caution
Do not use anything other than a mix of
DEX-COOL coolant that meets GM
Standard GMW3420 and clean, drinkable
water. Anything else can cause damage
to the engine cooling system and the
vehicle, which would not be covered by
the vehicle warranty.
Never dispose of engine coolant by putting
it in the trash, pouring it on the ground,
or into sewers, streams, or bodies of water. Have the coolant changed by an authorized
service center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
Checking Coolant
The vehicle must be on a level surface when
checking the coolant level.
It is normal to see coolant moving in the
upper coolant hose return line when the
engine is running. It is also normal to see
bubbles entering the surge tank through the
small hose.
Check to see if coolant is visible in the
coolant surge tank. If the coolant inside the
coolant surge tank is boiling, do not do
anything else until it cools down.
If coolant is visible but the coolant level is
not at or above the cold fill line, add a
50/50 mixture of clean drinkable water and
DEX-COOL coolant.
Be sure the cooling system is cool before
this is done.
It is normal for the coolant level in the
bottom chamber to rise and fall with
operating temperature and ambient
conditions. Coolant will evaporate from the
bottom chamber in normal operation. This
will happen faster when the vehicle is driven
for long periods in hot, dry conditions.
If no coolant is visible in the coolant surge
tank, add coolant as follows:
How to Add Coolant to the Coolant
Surge Tank
If no problem is found, check to see if
coolant is visible in the coolant surge tank.
If coolant is visible but the coolant level is
not at the bottom of the fill neck, add a
50/50 mixture of clean, drinkable water and
DEX-COOL coolant at the coolant surge tank,

but be sure the cooling system, including
the coolant surge tank pressure cap, is cool
before you do it.
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
{Warning
Spilling coolant on hot engine parts can
burn you. Coolant contains ethylene
glycol and it will burn if the engine parts
are hot enough.
Caution
Failure to follow the specific coolant fill
procedure could cause the engine to
overheat and could cause system
damage. If coolant is not visible in the
surge tank, contact your dealer.
1. Remove the coolant surge tank pressurecap from the top chamber when the
cooling system, including the coolant
surge tank pressure cap and upper
radiator hose, is no longer hot. Turn the pressure cap slowly
counterclockwise. If you hear a hiss, wait
for that to stop. This will allow any
pressure still left to be vented out the
discharge hose.
2. Keep turning the pressure cap slowly and remove it. Open the surge tank service
port cap to the lower chamber.3. Fill the surge tank top chamber with theproper mixture to the bottom of the fill
neck. The top chamber needs to be
completely full. Fill the surge tank
bottom chamber through the service port
to approximately half.

Vehicle Care 245
4. With the coolant surge tank pressure capoff and the surge tank service port cap
open, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the
coolant surge tank top chamber may be
lower. If the level is lower, add more of
the proper mixture to the surge tank top
chamber until the level reaches the
bottom of the fill neck.
5. Replace the surge tank pressure cap tightly and close the surge tank service
port cap.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Check the level in the surge tank top and
bottom chambers when the cooling system
has cooled down. If the coolant is not at the
proper levels, repeat Steps 1–3 and reinstall
the pressure cap and close the service port. If the coolant still is not at the proper levels
when the system cools down again, see
your dealer.
Engine Overheating
The vehicle has several indicators to warn of
the engine overheating.
There is an engine coolant temperature
gauge on the instrument cluster. See
Engine
Coolant Temperature Gauge 090. The
vehicle may also display a message on the
Driver Information Center (DIC).
If the decision is made not to lift the hood
when this warning appears, get service help
right away. See Roadside Assistance Program
0 317.
If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface.
Then check to see if the engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, do not
continue to run the engine. Have the vehicle
serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
Compartment
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
The hood extractor, if equipped, is
functional. It will allow water from rain and
car washes to enter the engine
compartment and contact hot surfaces.
