oil GMC SIERRA CLASSIC 2007 Owners Manual

Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm. 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.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START, and then released when the engine
begins cranking, the engine will continue
cranking until the vehicle starts or until
it exceeds the maximum cranking time allowed,
approximately 15 seconds to prevent cranking
motor damage. To prevent gear damage,
this system also prevents cranking if the
engine is already running. The engine cranking
can be stopped by turning the ignition switch
to the ACCESSORY or LOCK.Notice:Holding your key in START for longer
than 15 seconds at a time will disengage
the starter motor, cause your battery to be
drained much sooner, and add excessive heat
that can damage your starter motor. Try not
to hold the key in START for longer than
15 seconds and wait about 15 seconds
between each try to help avoid draining your
battery or damaging your starter.
2. If it does not start within 10 seconds, push the
accelerator pedal all the way to the oor,
while you hold the ignition key in START.
When the engine starts, let go of the key and
let up on the accelerator pedal. Wait about
15 seconds between each try.

3. Plug it into a normal, grounded 110-volt AC
outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
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 yourdealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.
Automatic Transmission Operation
If your vehicle has an automatic transmission,
it features an electronic shift position indicator
within the instrument panel cluster. This display
must be powered anytime the shift lever is moved
out of PARK (P). SeeFuses and Circuit Breakers
on page 600.
There are several different positions for your shift
lever.

If the transmission continues to operate above
265°F (130°C), contact your nearest dealer or the
GM Roadside Assistance Center. SeeRoadside
Assistance Program on page 644.
Notice:If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the
transmission. This could lead to costly repairs
that would not be covered by your warranty.
Do not drive your vehicle while the
transmission temperature gage reading is
above normal. See your dealer for service.
The following situations can cause the
transmission to operate at higher temperatures:
Towing a trailer
Hot outside air temperatures
Hauling a large or heavy load
Low transmission uid level
High transmission uid level
Restricted air ow to the radiator and the
auxiliary transmission oil cooler, if equipped.A temporary solution to reduce hotter transmission
operating temperatures may be to let the
transmission cool down. If the transmission is
operated at higher temperatures on a frequent
basis, seeScheduled Maintenance (Gasoline
Engine) on page 617for the proper transmission
maintenance intervals.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.

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).
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 some
other problem causing low oil pressure. Check
your oil as soon as possible. See “OIL PRESSURE
LOW” underDIC Warnings and Messages on
page 270andEngine Oil (Gasoline Engine)
on page 486.
{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.United StatesCanada
