2005 CHEVROLET OPTRA 5 check engine light

You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.

Engine Oil
If the oil pressure light
appears on the instrument
cluster, it means you
need to check your engine
oil level right away.
For more information, seeOil Pressure Light on
page 3-38.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your 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. See
Engine Compartment Overview on page 5-12for
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.
When to Add Engine Oil
If the oil is at or below the lower hole at the tip of the
dipstick (B), then you will need to add at least one quart
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 5-82.
Notice:Do not add too much oil. If your engine has
so much oil that the oil level gets above the upper
hole (A) that shows the proper operating range, your
engine could be damaged.
SeeEngine Compartment Overview on page 5-12for
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.

How to Check and Add Fluid
You do not need to check the fluid level unless you
suspect a clutch problem. 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.
The reservoir is located near the back of the engine
compartment on the driver’s side of the vehicle.
SeeEngine Compartment Overview on page 5-12for
more information on location.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-23.
A 50/50 mixture of clean, drinkable water and proper
coolant will:
•Give freezing protection down to−22°F (−30°C).
•Give boiling protection up to 268°F (131°C).
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as
they should.

Part B: Owner Checks and Services
Listed in this part are owner checks and services
which should be performed at the intervals specified to
help ensure the safety, dependability and emission
control performance of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in Part D.
At Each Fuel Fill
It is important for you or a service station attendant to
perform these underhood checks at each fuel fill.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-14for further
details.
Engine Coolant Level Check
Check the engine coolant level and add the proper
coolant mixture if necessary. SeeEngine Coolant on
page 5-20for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the windshield
washer tank and add the proper fluid if necessary. See
Windshield Washer Fluid on page 5-29for further details.
At Least Once a Month
Tire Ination Check
Visually inspect your tires and make sure tires are
inflated to the correct pressures. Do not forget to check
your spare tire. SeeTires on page 5-45for further details.
At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken airbag coverings,
and have them repaired or replaced. (The airbag system
does not need regular maintenance.)
