2007 CHEVROLET SILVERADO oil temperature

The additional ten minutes are considered a
second remote vehicle start.
Once two remote starts, or a single remote start
with one time extension has been done, the
vehicle must be started with the key.
After the key is removed from the ignition, the
vehicle can be remote started again.
The vehicle cannot be remote started if the key is
in the ignition, the hood is not closed, or if
there is an emission control system malfunction.
Also, the engine will turn off during a remote
vehicle start if the coolant temperature gets too
high or if the oil pressure gets low.
Vehicles that have the remote vehicle start feature
are shipped from the factory with the remote
vehicle start system enabled. The system may be
enabled or disabled through the DIC. See
“REMOTE START” underDIC Vehicle
Customization (With DIC Buttons) on page 291for
additional information. If your vehicle does not
have DIC buttons, see your dealer to enable
or disable the remote vehicle start system.Remote Start Ready
If your vehicle does not have the remote vehicle
start feature, it may have the remote start
ready feature. This feature allows your dealer to
add the manufacturer’s remote vehicle start
feature.
If your vehicle has the remote start ready feature,
your RKE transmitter will have extended range
that will allow you to lock or unlock your vehicle
from approximately 197 feet (60 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.

Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the driver’s
side of the engine compartment, near
the power steering uid reservoir.
3. Plug the cord 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 your dealer in the area
where you will be parking your vehicle. The dealer
can give you the best advice for that particular area.

Oil Pressure Gage
Your vehicle may have an engine oil pressure
gage. It 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 if readings
are outside the normal operating range, the oil
pressure light will come on. SeeOil Pressure Light
on page 266for more information.A reading outside the normal operating range 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 281andEngine Oil (Gasoline
Engine) on page 502.
{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

located on the instrument panel cluster. Pressing
the trip odometer reset stem will also turn off,
or acknowledge, DIC messages.
The DIC displays trip and vehicle system
information, and warning messages if a system
problem is detected.
If your vehicle does not have DIC buttons, you
can use the trip odometer reset stem to view the
following displays: odometer, engine hours,
trip odometer, transmission temperature, trailer
brake gain and output information for vehicles withthe Integrated Trailer Brake Control (ITBC)
system, oil life, Tire Pressure Monitor (TPM)
system programming for vehicles with a TPM
system, Remote Keyless Entry (RKE) transmitter
programming, and display language.

As soon as it is safe to do so, carefully pull your
vehicle over to the side of the road and turn
the ignition off. Check the wiring connection to the
trailer and turn the ignition back on. This
message clears if the trailer is reconnected. This
message also clears if you acknowledge it. If
this message still displays, either your vehicle or
the trailer needs service. See your dealer.
See “Integrated Trailer Brake Control System”
underTowing a Trailer on page 447for more
information.
DRIVER DOOR OPEN
This message displays and a chime sounds if the
driver’s door is not fully closed and the vehicle
is in a drive gear. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC.
ENGINE HOT A/C (Air Conditioning)
TURNED OFF
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. SeeEngine Coolant Temperature
Gage on page 260. To avoid added strain on a hot
engine, the air conditioning compressor
automatically turns off. When the coolant
temperature returns to normal, the air conditioning
compressor turns back on. You can continue to
drive your vehicle.
If this message continues to appear, have the
system repaired by your dealer as soon as
possible to avoid damage to the engine.
ENGINE OIL LOW ADD OIL
If your vehicle has an oil level sensor, this
message displays if the oil level in the vehicle is
low. Check the oil level and correct it as
necessary. You may need to let the vehicle cool
or warm up and cycle the ignition to be sure
this message clears.
This message clears itself after 10 seconds, until
the next ignition cycle. SeeEngine Oil (Gasoline
Engine) on page 502for additional information.

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 lower gear selection if the
transmission shifts too often (e.g., under heavy
loads and/or hilly conditions).You may also want to activate the tow/haul mode
if the transmission shifts too often. SeeTow/Haul
Mode Light on page 268.
When towing at high elevation on steep uphill
grades, consider the following: Engine coolant at
higher elevations will boil at a lower temperature
than at or near sea level. If you turn your
engine off immediately after towing at high
elevation 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 transmission
in PARK (P) at least ve minutes before turning the
engine off. If you do get the overheat warning,
seeEngine Overheating on page 517.

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.
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 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 SOON
message will come on. SeeDIC Warnings and
Messages on page 281. 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, your 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
service people who will perform this work using
genuine GM parts and reset the system. It is also
important to check your 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 your last oil change. Remember to reset the
oil life system whenever the oil is changed.
