performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment: .
Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“ Selecting the Right Engine Oil ”
in this section. .
Check the engine oil level
regularly and maintain the
proper oil level. See “ Checking
Engine Oil ” and “ When to Add
Engine Oil ” in this section. .
Change the engine oil at the
appropriate time. See
Maintenance Schedule on
page 11-3 . .
Always dispose of engine oil
properly. See “ What to Do with
Used Oil ” in this section. Checking Engine Oil It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
See Engine Compartment Overview
on page 10-7 for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running
recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{ Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.

Vehicle Care 10-92. Pull out the dipstick and wipe it
with a clean paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the tip
down, and check the level.
When to Add Engine Oil
It should be between the H (High)
and L (Low) marks. This is the
normal operating oil level range.
If the oil level is below the L (Low)
mark, remove the oil filler cap and
pour recommended oil through the
opening. See Engine Compartment
Overview on page 10-7 for the
location of the engine oil fill cap. Add some of the recommended oil
and then recheck the level. See
“ Selecting the Right Engine Oil ” in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12-2 . Add enough oil to put
the level somewhere in the proper
operating range. Do not overfill.
Push the dipstick all the way back in
when through.
{ CautionDo not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level 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
(Continued) Caution (Continued) be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
Selecting the Right Engine Oil Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See Recommended Fluids and
Lubricants on page 11-11 .
Specification
Ask for and use 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.

10-10 Vehicle Care
{ CautionFailure to use the recommended
engine oil can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification. Use of Substitute Engine Oils if
dexos1 is unavailable: In the event
that dexos1-approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil that
meets American Petroleum Institute
(API) approved specifications of the
appropriate viscosity grade. These
oils have the API certification mark
on the front of the container.
Viscosity Grade
Use SAE 5W-30 viscosity grade
engine oil.
Engine Oil Additives/Engine
Oil Flushes Do not add anything to the oil. The
recommended oils meeting the
dexos1 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.

when you are driving.
Cooling System The cooling system allows the
engine to maintain the correct
working temperature.
1. Coolant Recovery Tank 2. Radiator Pressure Cap
3. Engine Cooling Fans (Out
of View)
{ WarningAn electric engine cooling fan can
start even when the engine is not
running. To avoid injury, always
keep hands, clothing, and tools
away from any engine
cooling fan.
{ Warning
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 fire, and you
could be burned. Get any leak
fixed before you drive the vehicle. { CautionUsing coolant other than the
recommended engine coolant can
cause premature engine, heater
core, or radiator corrosion. In
addition, the engine coolant could
require changing sooner. Any
repairs would not be covered by
the vehicle warranty. Always use
the recommended engine coolant.
See Recommended Fluids and
Lubricants on page 11-11 .
Engine Coolant The cooling system in the vehicle is
filled with long life antifreeze
coolant. See Recommended Fluids
and Lubricants on page 11-11 .

Vehicle Care 10-15Checking Engine Coolant
Level
{ WarningYou 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.
{ CautionThis vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged. { WarningSteam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.
The vehicle must be on a level
surface when checking the coolant
level. Check the coolant level in the
reservoir when the engine is cold.
If the coolant level is below the MIN
level, add coolant to the MAX level.
If the reservoir is empty, check the
coolant level in the radiator when
the engine is cold. If there is
insufficient coolant in the radiator, fill
the radiator with coolant up to the
filler opening and also add it to the
reservoir up to the MAX level.
The vehicle contains long life
coolant. The life expectancy of the
factory-fill coolant is 168,000 km
(105,000 miles) or seven years.
Mixing any other type of coolant or
the use of non-distilled water will
reduce the life expectancy of the
factory-fill coolant. Refer to the
Recommended Fluids and
Lubricants on page 11-11 for more
details.
The engine coolant reservoir is a
pressurized tank. When installing
the cap, tighten.

10-16 Vehicle Care If the cooling system frequently
requires coolant, have it checked by
your dealer.
Changing Engine Coolant A dealer can change the engine
coolant. The service procedure can
be found in the service manual. See
Service Publications Ordering
Information on page 13-11 .
Improper servicing can result in
reduced heater performance and
engine overheating.
{ Warning.
To avoid the danger of being
scalded, never change the
coolant when the engine
is hot. .
Never remove the radiator or
engine coolant reservoir cap
when the engine is hot.
Serious burns could be
caused by high pressure fluid
escaping from the radiator.
(Continued) Warning (Continued) .
Avoid direct skin contact with
used coolant. If skin contact
is made, wash thoroughly
with soap or hand cleaner as
soon as possible. .
Keep coolant out of the reach
of children and pets.
Engine coolant must be disposed of
properly. Check your local
regulations.
Engine Overheating The vehicle has an engine coolant
temperature warning light on the
instrument cluster to warn of engine
overheating. See Engine Coolant
Temperature Warning Light on
page 5-17 .
If the decision is made not to lift the
hood when this warning appears,
but instead get service help right
away, see Roadside Assistance
Program on page 13-5 . 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 fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
See if the engine cooling fan speed
increases when idle speed is
doubled by pushing the accelerator
pedal down. If it does not, the
vehicle needs service. Turn off the
engine.
{ Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.

Vehicle Care 10-17If Steam is Coming from the
Engine Compartment
{ WarningSteam 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 the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool. Overheated Engine
Protection
Operating Mode The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level: .
The engine coolant temperature
warning light will illuminate. .
Engine power may be reduced. .
The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).
Engine power and under certain
conditions, vehicle speed will
decrease. Vehicle speed can be
controlled with the accelerator
pedal, but the vehicle may not
accelerate at the desired speed. The transmission will downshift or
upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and
engine coolant temperature is
reduced, vehicle speed can be
increased using the accelerator
pedal, and air conditioning cooling
function will automatically be turned
back ON.
If:
1. The engine coolant temperature
is not reduced.
2. The air conditioning cooling
function does not turn back ON.
3. The engine oil pressure low/
engine coolant temperature high
warning light illuminates, this
may indicate a malfunction.
Move the vehicle off the road in
a safe area and allow the engine
to cool. If after checking the oil
and coolant, the oil pressure
