Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0°F (−18°C) or colder, the engine coolant heater can
help. You will 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. At temperatures above 32°F (0°C),
use of the coolant heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on
the passenger’s side of the vehicle, above the
headlamp assembly.
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
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp
or glove box lamp. When the ignition is turned off, the
power to these features will automatically turn off

{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If you have the optional Head-Up Display (HUD), you
can see some of the driver information also available on
your instrument panel cluster. The information maybe displayed in English or metric units and appears as
an image focused out toward the front of your vehicle.
The HUD shows the following:
Speedometer Reading
Turn Signal Indicators
High-beam Indicator Symbol
CHECK GAGES Message (for low oil pressure,
high coolant temperature, low oil level, high/low
battery, brake, ABS and air bag)
Low Fuel Warning Symbol

Oil Pressure Gage (V6 Engine)
Readings above the shaded warning zone indicate the
normal operating range. Oil pressure may vary with
engine speed, outside temperature and oil viscosity.
A reading in the shaded warning zone may be caused
by a low oil level or another problem causing low oil
pressure. On vehicles with the systems monitor,
the CHECK GAGES light will come on and a warning
chime will sound.On vehicles with a DIC, a CHECK GAGES OIL
PRESSURE message will be displayed and a warning
chime will sound. SeeDIC Warnings and Messages
on page 3-62for more information.
{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 States

When you have the oil changed according to the
maintenance schedule, you will have to reset the engine
oil life system. To reset the engine oil life system, see
“How to Reset the Engine Oil Life System” underEngine
Oil Life System on page 5-20.
Tire Pressure Status:Press the SELECT button until
TIRE PRESSURE appears in the display. TIRE
PRESSURE NORMAL is displayed when the Check
Tire Pressure System believes your vehicle’s tire
pressures are normal. If a potential problem is detected,
the display will show CHECK TIRE PRESSURE and
the tire pressure status will show TIRE PRESSURE
LOW. If you see the CHECK TIRE PRESSURE
message, you should stop as soon as you can and
check all your tires for damage. If a tire is at, seeIf a
Tire Goes Flat on page 5-92. Also check the tire
pressure in all four tires as soon as you can. See
In ation - Tire Pressure on page 5-80andCheck Tire
Pressure System on page 5-83.DIC Warnings and Messages

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 20W-50.
Oils meeting these
requirements should also
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certi ed by the American
Petroleum Institute (API).
You should look for this information on the oil container,
and useonlythose oils that are identi ed as meeting
GM Standard GM6094M and have the starburst symbol
on the front of the oil container.Notice:Use only engine oil identi ed as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certi ed 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 will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Do not add anything to your oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all you will need for good performance
and engine protection.
