2007 CHEVROLET COLORADO oil change

To prevent gear damage, this system also
prevents cranking if the engine is already
running. Engine cranking can be stopped
by turning the ignition switch to the ACC or
LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.
2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too
much gasoline. Try pushing the accelerator
pedal all the way to the oor and holding
it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator.If the vehicle starts briey but then stops
again, do the same thing. This clears the
extra gasoline from the engine. Do not race
the engine immediately after starting it.
Operate the engine and transmission gently
until the oil warms up and lubricates all
moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer/retailer. If you do not, your engine
might not perform properly. Any resulting
damage would not be covered by your
vehicle’s warranty.

Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could
be damaged. Avoid making very sharp
turns while trailering.
When you’re turning with a trailer, make wider turns
than normal. Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring and a heavy-duty turn signal asher.
The arrows on your instrument panel will ash
whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to
turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if
the bulbs on the trailer are burned out.Thus, you may think drivers behind you are seeing
your signal when they are not. It’s important to
check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before
you start down a long or steep downgrade.
If you don’t shift down, you might have to use
your brakes so much that they would get hot
and no longer work well.
When towing at high altitude on steep uphill
grades, consider the following: Engine coolant
will boil at a lower temperature than at normal
altitudes. If you turn your engine off immediately
after towing at high altitude on steep uphill grades,
your vehicle may show signs similar to engine
overheating. To avoid this, let the engine run
while parked (preferably on level ground) with
the automatic transmission in PARK (P) (or
the manual transmission out of gear and the
parking brake applied) for a few minutes before
turning the engine off. If you do get the overheat
warning, seeEngine Overheating on page 348.

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.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter.
This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil changewill be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE OIL message will
come on. SeeDIC Warnings and Messages on
page 202. Change the oil as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions,
the oil life system might not indicate that an
oil change is necessary for over a year. However,
the engine oil and lter must be changed at
least once a year and at this time the system must
be reset. Your dealer/retailer has trained people
who will perform this work using genuine parts and
reset the system. It is also important to check
the oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since
your last oil change. Remember to reset the oil
life system whenever the oil is changed.
336

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change the engine oil and lter based on vehicle
use. Whenever the oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change the oil prior to a CHANGE OIL message
being turned on, reset the system.
To reset the Engine Oil Life system:
1. With the engine off, turn the ignition to ON.
2. Press and release the stem in the lower center
of the instrument cluster until the OIL LIFE
message is displayed.
3. Once the alternating OIL LIFE and RESET
messages appear, press and hold the stem
until several beeps sound. This conrms
that the oil life system has been reset.
4. Turn the key to LOCK.
If the CHANGE OIL message comes back on
when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.
SeeDIC Warnings and Messages on page 202.
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 lter 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/retailer, a service station, or a local
recycling center for help.

Engine Air Cleaner/Filter
The engine air cleaner/lter is located in the
engine compartment on the passenger’s side of
the vehicle. SeeEngine Compartment Overview
on page 332for more information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval.
SeeScheduled Maintenance on page 442for
more information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine
oil change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect or replace the engine air cleaner/lter,
do the following:
1. Unfasten the clips that hold the cover on
and remove the cover.
2. Lift out the engine air cleaner/lter.
3. Inspect or replace the air lter. SeeNormal

{CAUTION:
Operating the engine with the air
cleaner/lter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop ames
if the engine backres. If it is not there
and the engine backres, you could be
burned. Do not drive with it off, and be
careful working on the engine with the
air cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre
can cause a damaging engine re. And, dirt
can easily get into your engine, which will
damage it. Always have the air cleaner/lter
in place when you are driving.
Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
A good time to check your automatic transmission
uid level is when the engine oil is changed.
Change the uid and lter at the intervals listed in
Additional Required Services on page 444, and
be sure to use the transmission uid listed in
Recommended Fluids and Lubricants on page 452.
How to Check Automatic
Transmission Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealer/retailer
service department.
