Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
dexos specification and displaying
the dexos certification mark 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.
Black plate (16,1)Chevrolet Volt Owner Manual - 2011
10-16 Vehicle Care
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 two years. The engine oil and
filter must be changed at least
once every two years 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.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Use the SELECT knob to selectOIL LIFE on the DIC menu.
2. Press SELECT to start the OIL LIFE reset procedure.
3. The DIC menu will display “Are
you sure that you want to reset?”
Use SELECT to choose YES to
reset oil life or NO to exit and
return to the previous menu.
4. If YES is selected, the DIC menu will display RESET OIL LIFE for
a short time and then 100% OIL
LIFE will be displayed when
OIL LIFE is successfully reset.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Engine Air Cleaner/Filter
See Engine Compartment Overview
on page 10‑10 for the location of the
engine air cleaner/filter.
When to Inspect the Engine Air
Filter
Inspect the air filter at the scheduled
maintenance intervals and replace
it at the first oil change after each
80 000 km (50,000 mi) interval.
See Scheduled Maintenance on
page 11‑2 for more information.
If driving in dusty/dirty conditions,
inspect the air filter at each engine
oil change.
How to Inspect the Engine Air
Filter
To inspect the air filter, remove it
from the engine air cleaner/filter
assembly and lightly shake to
release loose dust and dirt. If the
air filter remains covered with dirt,
a new air filter is required.

Headlamp Aiming
The headlamp aiming system has
been preset at the factory.
If the vehicle is damaged in an
accident, the aim of the headlamps
may be affected and adjustment
may be necessary.
It is recommended that a dealer
adjust the headlamps. To re-aim
the headlamps yourself, use the
following procedure.
The vehicle should be properly
prepared as follows:
.The vehicle should be placed so
the headlamps are 7.6 m (25 ft)
from a light‐colored wall.
.The vehicle must have all four
tires on a level surface which is
level all the way to the wall.
.The vehicle should be placed so
it is perpendicular to the wall or
other flat surface.
.The vehicle should not have any
snow, ice, or mud on it.
.The vehicle should be fully
assembled and all other work
stopped while headlamp aiming
is being performed.
.The vehicle should be normally
loaded with a full tank of fuel and
one person or 75 kg (160 lbs)
sitting on the driver seat.
.Tires should be properly inflated.
Headlamp aiming is done with the
vehicle's low-beam headlamps.
The high-beam headlamps will be
correctly aimed if the low-beam
headlamps are aimed properly. To adjust the vertical aim:
1. Open the hood. See
Hood on
page 10‑9 for more information.2. Locate the aim dot on the lens of
the low‐beam headlamp.
3. Measure the distance from the ground to the aim dot on the
low‐beam headlamp. Record
the distance.

Vehicle Care 10-61
Tire Inspection
GM recommends that the
tires, including the spare, be
inspected for signs of wear or
damage at least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord
or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). The first
rotation is the most important.
SeeScheduled Maintenance on
page 11‑2.
Tires are rotated to achieve a
more uniform wear for all tires.
Any time unusual wear is
noticed, rotate the tires as
soon as possible, and
check the wheel alignment.
See When It Is Time for New
Tires on page 10‑62 andWheel
Replacement on page 10‑67.
Use this rotation pattern when
rotating the tires.
Adjust the front and rear tires
to the recommended inflation
pressure on the Tire and
Loading Information label
after the tires have been
rotated. See Tire Pressure on
page 10‑54 andVehicle Load
Limits on page 9‑14.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑57.
