Engine Oil
To ensure proper engine
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 Engine Oil
Life System on page 10‑12.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
If the engine oil pressure light
comes on, check the engine oil level
right away. The oil pressure light is
on the instrument panel cluster. See
Engine Oil Pressure Light on
page 5‑18. Check the engine oil
level regularly; this is an added
reminder.

10-10 Vehicle Care
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 oil
must be warm and the vehicle must
be on level ground. The engine oil
dipstick handle is a yellow loop. See
Engine Compartment Overview on
page 10‑8for the location of the
engine oil dipstick.
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.
2. Pull out the dipstick and clean it with a 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
If the oil is below the MIN
(minimum) mark on 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.
Notice: 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 upper mark 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 10‑8 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
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade:
Specification
Use and ask for engine oils with the
dexos™ certification mark. Oils
meeting the requirements of the
vehicle should have the dexos™
certification mark on the container.

Black plate (11,1)Chevrolet Aveo Owner Manual - 2011
Vehicle Care 10-11
This certification mark indicates that
the oil has been approved to the
dexos™specification.
Notice:Use only engine oil that is
approved to the dexos™
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine oils
approved to the dexos™
specification will show the
dexos™ symbol on the container.
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty. If you are
unsure whether the oil is
approved to the dexos™
specification, ask your service
provider. Use of Substitute Engine Oils if
dexos™
is unavailable: In the event
that dexos™ approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil
displaying the API Starburst symbol
and of SAE 5W-30 viscosity grade.
Use of oils that do not meet the
dexos™ specification, however, may
result in reduced performance under
certain circumstances.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity oils such as
SAE 10W‐30, 10W‐40, or 20W-50.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below −29°C
(−20°F), an SAE 0W-30 oil should

Black plate (12,1)Chevrolet Aveo Owner Manual - 2011
10-12 Vehicle Care
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, be sure to always select an
oil that meets the required
specification, dexos™. See
“Specification”in this section for
more information.
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 the Engine Oil Life
System, a computer system that
indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
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 light
displays. Change the oil as soon as
possible within the next 1 000 km
(600 miles). 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

Black plate (13,1)Chevrolet Aveo Owner Manual - 2011
Vehicle Care 10-13
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 miles)
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. Turn the ignition to ON/RUN,with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
3. Turn the key to LOCK/OFF. If the change engine oil light comes
back on when the vehicle is started,
the engine oil life system has not
reset. Repeat the procedure.
Automatic Transmission
Fluid
When to Check Automatic
Transmission Fluid
Check the automatic transmission
fluid level at least twice a year. Add
fluid if needed. See
Scheduled
Maintenance on page 11‑2.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, it may be decided to
have this done at the dealer service
department.
If not taken to the dealer, be sure to
follow all the instructions here, or a
false reading on the dipstick could
result. Notice:
Too much or too little
fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Wait at least 30 minutes before
checking the transmission fluid level
if the vehicle has been driven:
.When outside temperatures are
above 32°C (90°F).
.At high speed for quite a while.
.In heavy traffic —especially in
hot weather.
To get the right reading, the fluid
should be at normal operating
temperature, which is 70°C to 80°C
(158°F to 176°F).

Black plate (14,1)Chevrolet Aveo Owner Manual - 2011
10-14 Vehicle Care
Get the vehicle warmed up by
driving about 24 km (15 miles) when
outside temperatures are above
10°C (50°F). If it is colder than
10°C (50°F), you may have to
drive longer.
Checking the Fluid Level
Prepare the vehicle as follows:
1. Park the vehicle on a levelplace. Keep the engine running.
2. With the parking brake applied, place the shift lever in P (Park).
3. With your foot on the brake pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, position the
shift lever in P (Park).
4. Let the engine run at idle for three to five minutes. Then, without shutting off the
engine, follow these steps:
1. Locate the automatic
transmission dipstick which is
located toward the front of the
engine compartment, near the
power steering fluid reservoir.
See Engine Compartment
Overview on page 10‑8 for more
information on location.
2. Pull out the dipstick and wipe it with a clean rag or paper towel.
3. Push the dipstick back in all the way, wait three seconds, and
then pull it back out again.
4. Check both sides of the dipstick.The fluid should be between the
MIN (A) and MAX (B) mark of
the hot area of the dipstick. 5. If the fluid level is in the
acceptable range, push the
dipstick back in all the way.
How to Add Automatic
Transmission Fluid
Refer to the Maintenance Schedule
to determine what kind of
transmission fluid to use. See
Recommended Fluids and
Lubricants on page 11‑6.
If the fluid level is low, add only
enough of the proper fluid to bring
the level into the area between the
two dimples in the hot range on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add
enough fluid at the dipstick hole
to bring it to the proper level.
It does not take much fluid,
generally less than 0.5 L (1 pint).
Do not overfill.

Black plate (15,1)Chevrolet Aveo Owner Manual - 2011
Vehicle Care 10-15
Notice:Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑6.
3. After adding fluid, recheck the fluid level as described under
“How to Check Automatic
Transmission Fluid” earlier in
this section.
4. When the correct fluid level is obtained, push the dipstick back
in all the way.
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 the
dealer service department and have
it repaired as soon as possible. See Recommended Fluids and
Lubricants on page 11‑6
for the
proper fluid to use.
Hydraulic Clutch
There is one reservoir for both the
brake and the hydraulic clutch fluid.
See Brakes on page 10‑24 for more
information.
The hydraulic clutch linkage in the
vehicle is self-adjusting. The master
cylinder reservoir is filled with
hydraulic fluid.
A fluid loss in this system could
indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
Refer to the Maintenance Schedule
to determine how often to check the
fluid level in the master cylinder
reservoir and for the proper fluid.
See Scheduled Maintenance on
page 11‑2 andRecommended
Fluids and Lubricants on page 11‑6.
How to Check and Add Fluid
The reservoir is located near the
back of the engine compartment on
the driver side of the vehicle. See
Engine Compartment Overview on
page 10‑8 for more information on
location.
To check the fluid level, look on the
side of the reservoir. If the fluid
reaches the MAX (A) mark on the
reservoir, the fluid level is correct.
If the fluid does not reach the
MIN (B) mark on the reservoir,
then fluid needs to be added.

Engine Air Cleaner/Filter
The engine air cleaner/filter is
located in the engine compartment
on the passenger side of the
vehicle. SeeEngine Compartment
Overview on page 10‑8 for more
information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/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 you are driving in
dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect the engine air cleaner/
filter, remove the filter from the
vehicle and lightly shake the filter to release loose dust and dirt. If the
filter remains covered with dirt, a
new filter is required.
To inspect or replace the air
cleaner/filter:
1. Remove the screws and lift off
the cover.
2. Inspect or replace the engine air cleaner/filter.
3. Put the cover back on tightly and tighten the screws.
See Scheduled Maintenance on
page 11‑2 for replacement intervals.
{WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
