{Warning
Lifting a vehicle can cause an
injury. The vehicle can slip off the
jack and roll over you or other
people. You and they could be
badly injured. Find a level place
to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine.
To be even more certain the
vehicle will not move, put blocks
in front of and behind the wheels.
{Warning
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack,
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle or the vehicle
may fall and cause injury to you
or others.
If a jack is used to lift the vehicle,
follow the instructions that came
with the jack, and be sure to use the
correct lifting points to avoid
damaging the vehicle.

Doing Your Own
Service Work
{Warning
It can be dangerous to work on
your vehicle if you do not have
the proper knowledge, service
manual, tools, or parts. Always
follow owner manual procedures
and consult the service manual
for your vehicle before doing any
service work.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see Service
Publications Ordering Information
on page 13-11.

Vehicle Care 10-13
Obtaining an accurate oil level
reading is essential:
1. If the engine has been runningrecently, turn off the engine and
check within five and 10 minutes
of shutoff. 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.
2. Pull 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
(Except Z51 and Z06)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) 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.
See Track Events and Competitive
Driving on page 9-5 for additional
information on engine oil.
{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 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
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.
See Engine Compartment Overview
on page 10-7 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.

4. Remove the dipstick from the external engine oil tank and wipe
it with a clean lint-free paper
towel or a cloth. Re-insert the
dipstick into the external oil tank,
pushing it all the way in until it
stops.
5. Remove the dipstick from the oil tank and read the level on the
cross-hatched area.
When to Add Engine Oil
(Z51 and Z06)
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 and then recheck the level.
See “Selecting the Right Engine Oil”
for an explanation of what kind of oil
to use. For engine oil crankcase
capacity, see Capacities and
Specifications on page 12-2.

Vehicle Care 10-17
GM recommends Mobil 1®engine
oils that show the dexos1 approved
logo for its dry sump equipped
engines.
{Caution
Failure 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.
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. When selecting an oil
of the appropriate viscosity grade,
always select an oil of the correct
specification. See “Specification”
earlier in this section for more
information.
For track events or competitive
driving, use Mobil 1®15W-50 engine
oil. An instrument cluster warning
light will be illuminated at high oil
temperatures. See Driver
Information Center (DIC) on
page 5-26.
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.
