2007 CHEVROLET OPTRA 5 Owners Manual

Hood Release
To open the hood, do the following:
1. Pull the hood
release handle
inside the vehicle.
It is located on the
lower left side
of the instrument
panel.
2. Then go to the front of the vehicle and
lift up the secondary hood release lever.
The secondary hood release lever is located
under the front center of the hood.3. Lift the hood, release the hood prop from its
retainer and place the hood prop into the slot
in the hood.
4. Before closing the hood, be sure all the filler
caps are on properly. Then lift the hood to
relieve pressure on the hood prop. Remove
the hood prop from the slot in the hood
and return the prop to its retainer. Lower the
hood 12 inches (30 cm) above the vehicle
and release it to latch fully. Check to
make sure the hood is closed and repeat the
process if necessary.

Engine Oil
If the engine oil
pressure light appears
on the instrument
cluster, check the
engine oil level
right away.
For more information, seeOil Pressure Light on
page 175. You should check the engine oil
level regularly; this is an added reminder.
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. 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.
SeeEngine Compartment Overview on page 258
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull 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.
260

When to Add Engine Oil
If the oil is below the lower hole at the tip of
the dipstick (B), you need to add at least
one quart/liter of oil. But you must use the
right kind. This section explains what kind of oil
to use. For engine oil crankcase capacity,
seeCapacities and Specifications on page 352.Notice:Do not add too much oil. If the
engine has so much oil that the oil level
gets above the upper hole (A) that shows
the proper operating range, the engine could
be damaged.
SeeEngine Compartment Overview on page 258
for the location of the engine oil fill cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range, between
the holes on the dipstick. Push the dipstick all
the way back in when you are through.
261

What Kind of Engine Oil to Use
Look for two things:
•GM6094M
Your vehicle’s engine requires oil meeting GM
Standard GM6094M. Look for and use only
an oil that meets GM Standard GM6094M.
•SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
also have the starburst
symbol on the
container. This symbol
indicates that the oil
has been certified by the
American Petroleum
Institute (API).
Look for this information on the oil container, and
use only those oils that are identified as meeting
GM Standard GM6094M and have the starburst
symbol on the front of the oil container.
262

Notice:Use only engine oil identied as
meeting GM Standard GM6094M and showing
the American Petroleum Institute Certied
For Gasoline Engines starburst symbol.
Failure to use the recommended oil can
result in engine damage not covered by your
warranty.
GM Goodwrench
®oil meets all the requirements
for your vehicle.
If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both provide
easier cold starting and better protection for
the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet
GM Standard GM6094M are all you need for
good performance and engine protection.
When to Change Engine Oil
If any one of these is true for you, use the
short trip/city maintenance schedule:
•Most trips are less than 5 miles (8 km).
This is particularly important when outside
temperatures are below freezing.
•Most trips include extensive idling, such as
frequent driving in stop-and-go traffic.
•You frequently tow a trailer or use a carrier
on top of your vehicle.
•The vehicle is used for delivery service,
police, taxi, or other commercial application.
Driving under these conditions causes engine oil
to break down sooner. If any one of these is
true for your vehicle, change the oil and filter every
3,000 miles (5 000 km) or 3 months, whichever
occurs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and
filter every 7,500 miles (12 500 km) or 12 months,
whichever occurs first. Driving a vehicle with a
fully warmed engine under highway conditions will
cause engine oil to break down slower.
263

What to Do with Used Oil
Used engine oil contains certain elements that may
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, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If you have a problem properly disposing of
used oil, ask your dealer, a service station, or a
local recycling center for help.
Engine Air Cleaner/Filter
The engine air cleaner/filter is located in the
engine compartment on the passenger’s side of
the vehicle. SeeEngine Compartment Overview
on page 258for more information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the engine air cleaner/filter every
15,000 miles (25 000 km) and replace it every
30,000 miles (50 000 km). 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
caked with dirt, a new filter is required.
