4. Remove the dipstick again and read thelevel on the cross-hatched area. Re-insert
the dipstick and push it all the way in
until it stops.
5. Turn the engine off.
When to Add Engine Oil
If the oil is below the cross-hatched area at
the tip of the dipstick, add 1 L (1 qt) of the
recommended oil through the oil fill cap
opening in the oil tank fill tube and then
recheck the level. See “Selecting the Right
Engine Oil” later in this section for the type
of oil to use. For engine oil crankcase
capacity, see Capacities and Specifications
0 325.
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 0238 for
the location of the external engine oil tank
dipstick and fill cap.
Add enough oil to put the level somewhere
in the proper operating range. Push the
dipstick all the way back into the oil tank
tube when finished.

and there could be no engine oil on the
dipstick. This is normal since the dipstick is
designed to read the engine oil level only
after the engine has run long enough to
reach normal operating temperature. Do not
add engine oil based on cold engine dipstick
readings. The engine oil level on the dipstick
must be checked while the engine is running
at idle.
To check the engine oil:1. Turn the engine on and let it warm up to at least 80 °C (175 °F).
2. Once the engine is warm, check the oil while the engine is running at idle.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
3. Remove the dipstick and wipe it with a clean lint-free paper towel or a cloth.
Re-insert the dipstick and push it all the
way in until it stops.

252 Vehicle Care
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” previously in this section.
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, 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 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.
This vehicle has a racetrack-ready dry sump
engine lubrication system. This high
performance system operates differently
than a standard engine lubrication system
and requires a special procedure when
changing the engine oil and filter. See
Engine Oil (5.5L LT6 Engine)
0246 or
Engine Oil (6.2L LT2 Engine) 0249.
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 may
not indicate that an oil change is 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.

When to Replace the Dual Clutch
Transmission Fluid Filter
This vehicle has a computer that indicates
when to change the transmission external
canister fluid filter. This is based on the
number of miles driven as outlined in the
Service and Maintenance section. For the
fluid filter life system to work properly, the
system must be reset every time the filter is
replaced. When the system has calculated
that the external canister filter is near the
mileage interval, a REPLACE TRANSMISSION
OIL FILTER SOON message comes on. Replace
the external canister filter before the
indicator reaches 0%.
Failure to replace the transmission filter at
required intervals could lead to suboptimal
transmission performance. Your dealer has
trained service technicians who will replace
the external canister filter and reset the
system. If the system is ever reset
accidentally, the filter should be replaced
according to the service intervals indicated
in the Service and Maintenance section until

Warning (Continued)
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.
Use a mixture of 40% DEX-COOL coolant and
60% clean, drinkable water. If using this
mixture, nothing else needs to be added.
This mixture:
.Gives freezing protection down to −28 °C
(−18 °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.
If ambient temperatures are anticipated
below
−28 °C (−18 °F), make sure a proper
mixture ratio of 50% DEX-COOL coolant and
50% clean, drinkable water is used.
Checking Coolant
Be sure the cooling system is cool and that
the vehicle is on a level surface.
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 mixture of
40% DEX-COOL coolant and 60% clean,
drinkable water at the coolant recovery
tank, but be sure the cooling system is cool
before this is done. See Engine Overheating
0 261. The surge tank is in the engine
compartment. See
Engine Compartment
Overview 0238.
When the engine is cold, the coolant level
should be at the COLD FILL indicator in the
coolant surge tank.
When the engine is hot, the level could be
higher than the COLD FILL indicator. If the
coolant is below the COLD FILL indicator
when the engine is hot, there could be a
leak in the cooling system.
If the coolant is low, add the coolant or take
the vehicle to your dealer for service.
