Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Option) 3. Plug it into a normal, grounded 1 10-volt AC outlet.
I
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt AC outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
In very cold weather, 0 OF (- 1 8 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord, located
behind the vehicle’s passenger side headlamp fixture.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you
don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind
of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your Chevrolet dealer in the area where you’ll be
parking your vehicle. The dealer can give you the best
advice for that particular area.

CHG OIL
SOON
The CHANGE OIL
SOON light should come
on as a bulb check when
you start the engine. If this
light stays on for about
20 seconds after you turn
on the ignition, have the
oil changed.
Security Light
SECURITY
This light will come on
when you
turn the key to
START and stay on until the
vehicle starts. It will also
come on and stay on
if your
key is too dirty or wet for
the PASS-Key
I1 system to
read the resistor pellet.
When to change your oil also depends on driving habits
and conditions because they directly affect engine speed,
coolant temperature and vehicle speed. Because of this,
the CHANGE
OIL SOON light may come on as early as
2,000 miles (3,200 km) or less for harsh conditions.
Remember, after changing your engine oil, the system
must be reset; with the ignition key in the RUN position,
but the engine
off, fully push and release the accelerator
pedal three times within five seconds. If the CHANGE
OIL SOON light flashes two times, the system is reset.
However
if the light comes on and stays on for five
seconds, it did not reset. You’ll need
to reset the
system again. If the resistor pellet is
damaged or missing, the light
will flash.
If you’re driving and the light comes on and remains on,
your PASS-Key I1 system is not working properly. Your
vehicle is not protected by PASS-Key
11, and you should
see your dealer.

DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
As shown in the chart, if you have the 3.4L DOHC
engine, SAE 1OW-30 is best for your vehicle. However,
you can use
SAE 5W-30 if it’s going to be colder than
60°F ( 16°C) before your next oil change. When it’s
very cold, you should use
SAE 5W-30. These numbers
on an oil container show its viscosity, or thickness.
Do
not use other viscosity oils, such as SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified 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 where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.

Don’t add anything to your oil. Your Chevrolet dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 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).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of

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, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs fiist. (See “Change Oil Soon” Light in
the Index.)
If none of them is true, use the long triphighway
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 causes engine oil
to
break down slower.
(See “Change Oil Soon” Light in the Index.)
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t 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 throw
away 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 real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever 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 your used oil,
ask your dealer, a service station or a local recycling
center for help.

Operating the engine with the air cleaner off can
cause you or others to be burned. The
air cleaner
not only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it off, and be careful working on the engine with
the air cleaner
off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage
it. Always
have the
air cleaner in place when you’re driving.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level
is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do
not require changing.
See “Scheduled Maintenance Services” in the Index.
