2007 CHEVROLET TRAIL BLAZER oil temperature

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 do not,
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 dealer in the area
where you will be parking your vehicle. The
dealer/retailer can give you the best advice for that
particular area.
Active Fuel Management™
Your vehicle’s V8 engine may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders,
depending on your driving conditions.When less power is required, such as cruising at a
constant vehicle speed, the system will operate
in the half cylinder mode, allowing your vehicle to
achieve better fuel economy. When greater
power demands are required, such as accelerating
from a stop, passing, or merging onto a freeway,
the system will maintain full-cylinder operation.
Automatic Transmission Operation
There are several different positions for your gear
shift lever.

Oil Pressure Gage
The oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) when
the engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals).
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above
the low pressure zone indicate the normal operating
range.
A reading in the low pressure zone may be
caused by a dangerously low oil level or other
problems causing low oil pressure.

Service Four-Wheel Drive
Warning Light
This light should come
on briey when you
turn on the ignition,
as a check to show
you it is working.
The service four-wheel drive light comes on,
except for the SS model, to indicate that there
may be a problem with the drive system and
service is required. Malfunctions can be indicated
by the system before any problem is apparent,
which may prevent serious damage to the vehicle.
This system is also designed to assist your GM
dealer in correctly diagnosing a malfunction.
Check Gages Warning Light
The check gages light
will come on briey
when you are starting
the engine.
If the light comes on and stays on while you
are driving, check your coolant temperature and
engine oil pressure gages to see if they are in
the warning zones.
Gate Ajar Light
If this light comes on,
the liftgate or liftglass
is not completely shut.
Close the liftgate or liftglass. Never drive with the
liftgate or liftglass even partially open.

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
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 gearbefore
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.
You can tow in DRIVE (D). You may want to shift
the transmission to THIRD (3) or a lower gear,
under heavy loads or hilly conditions.
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) for a few
minutes before turning the engine off. If you do get
the overheat warning, seeEngine Overheating
on page 418.

Oils meeting
these requirements
should have the
starburst symbol
on the container.
This symbol indicates
that the oil has been
certied by the
American Petroleum
Institute (API).
Look for this information on the oil container, and
use only those oils that are identied as meeting
GM Standard GM6094M and have the starburst
symbol on the front of the oil container.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.

with a Mobil 1®synthetic oil, which meets all
requirements for your vehicle.
Substitute Engine Oil: When adding oil to
maintain engine oil level, oil meeting
GM Standard GM4718M may not be available.
You can add substitute oil designated SAE 5W-30
with the starburst symbol at all temperatures.
Substitute oil not meeting GM Standard GM4718M
should not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
standards 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 change
will 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 engine oil
light will come on, and, if your vehicle has a
Driver Information Center (DIC), a CHANGE
ENGINE OIL message will come. SeeChange
Engine Oil Light on page 216andDIC
Warnings and Messages on page 224.Change your 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 may 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 has GM-trained people who will
perform this work using genuine GM 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 your oil at 3,000 miles (5 000 km)
since the last oil change. Remember to reset the
oil life system whenever the oil is changed.
