BATTERY VOLTAGE LOW - 6: This message
will appear when the electrical system is charging less
than 10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may take a
few hours to do so. Consider using an auxiliary charger
(be sure to follow the manufacturer's instructions) to
boost the battery after returning home or to a final
destination. If this message appears while driving or
after starting your vehicle and stays on, have it checked
immediately to determine the cause of this problem.
To help the generator recharge the battery quickly, you
can reduce the load on the electrical system by turning off
the accessories. You can monitor battery voltage on the
DIC by pressing the INFO button. The normal range
is 11.5 to 15.5 volts.
CHANGE ENGINE OIL
- 82: This means that the
life of the engine oil has expired and it should be
changed within 200 miles. See ªEngine Oilº and
ªFilter Recommendationsº in the Maintenance Schedule
booklet. After an oil change, the Oil Life Indicator must
be reset. See ªOil Life Indicator, How to Resetº in
the Index.CHANGE TRANS FLUID
- 47: This message will
appear when it is time to replace the transaxle fluid. See
the Maintenance Schedule booklet for the proper fluid
and change intervals.
CHECK BRAKE FLUID
- 37: This message will
display if the ignition is in ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. See ªBrake
System Warning Lightº in the Index.
CHECK COOLANT LEVEL
- 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.
CHECK FUEL GAGE
- 50: (Analog Cluster Only)
This message will appear when the fuel supply is less
than 5 gallons (18.9 L) and the display is turned off.
A single chime will also sound when this message
is displayed.
CHECK GAS CAP
- 61: This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it's fully tightened.

2-114
The DIC may display a CHANGE ENGINE OIL
message. Always keep a written record of the mileage
and date when you changed your oil. For more
information, see the Maintenance Schedule booklet.
If you see CHANGE ENGINE OIL, it means the
oil life is gone and you should change the oil right away.
The system doesn't check how much oil you have,
so you'll still have to check for that. To see how,
see ªEngine Oilº in the Index.
When the oil is changed, you'll need to reset the system.
See ªOil Life Indicator, How to Resetº in the Index.Night Vision System (Option)
The Night Vision System can help you see better when
you drive at night. The system works by sensing heat
given off by objects in its field of view. Warmer objects,
such as pedestrians, animals and other moving vehicles,
will appear whiter. Colder objects, such as the sky, signs
and parked vehicles, will appear darker.

Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº and ªRecreational Vehicle Towingº in
the Index.
Engine Overheating
You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE OVERHEATED,
STOP ENGINE message on the Driver Information
Center (DIC). You will also hear a chime. There is
also an engine temperature warning light and/or gage
on the instrument panel cluster. See ªEngine Coolant
Temperature Warning Lightº or ªEngine Coolant
Temperature Gageº in the Index.
Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED, STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and engine
performance. This operating mode allows your vehicle
to be driven to a safe place in an emergency; you may
drive up to 50 miles (80 km). Towing a trailer in the
overheat protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and
reset the oil life indicator. See ªEngine Oilº in
the Index.

6-14
As in the chart shown previously, SAE 5W-30 is best for
your vehicle. However, you can use SAE 10W
-30 if it's
going to be 0F (
-18C) or above. These numbers on an
oil container show its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 20W
-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified 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 where the temperature falls below
-20F (-29C), consider using 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
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil
Your vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that the
oil needs changing, the GM Oil Life System will
indicate that a change is necessary. The mileage between
oil and filter changes will vary depending on how you
drive your vehicle
-- usually between 3,000 miles
(5 000 km) and 10,000 miles (16 000 km) since your
last oil and filter change. Under severe conditions, the
system may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 10,000 miles
(16 000 km) or 12 months (whichever occurs first)
without an oil change.
The system won't detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner. Remember to
reset the Oil Life Indicator whenever the oil is changed.

6-15
How to Reset the Oil Life Indicator
After the oil has been changed, display the OIL LIFE
message by pressing the INFO button. Then press and
hold the RESET button until the display shows 100%
ENGINE OIL LIFE. This resets the oil life index. The
percentage of oil life remaining may be checked at any
time by pressing the INFO button several times until the
OIL LIFE message appears. For more information on
the oil life feature, see ªOil Life Indicatorº in the Index.What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't 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 throw
away 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 real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever 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 your used oil,
ask your dealer, a service station or a local recycling
center for help.
