StabiliTrak®System
Your vehicle may be equipped with the StabiliTrak®
system which combines antilock brake, traction and
stability control systems and helps the driver
maintain directional control of the vehicle in most
driving conditions.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic
checks to ensure there are no problems. You may
hear or feel the system working. This is normal and
does not mean there is a problem with your vehicle.
The system should initialize before the vehicle
reaches 20 mph (32 km/h). In some cases, it may
take approximately two miles of driving before the
system initializes.
If the system fails to turn on or activate, the
StabiliTrak
®light along with one of the following
messages will be displayed on the Driver
Information Center (DIC): TRACTION CONTROL
OFF, SERVICE TRACTION CONTROL,
STABILITRAK OFF, SERVICE STABILITRAK.If these DIC messages appear, make sure the
StabiliTrak
®system has not been turned off using
the StabiliTrak®on/off button. Then turn the
steering wheel clockwise from the nine o’clock
position to the three o’clock position. If this clears
the message(s), your vehicle does not need
servicing. If this does not clear the message(s),
then turn the vehicle off, wait 15 seconds, and then
turn it back on again to reset the system. If any
of these messages still appear on the Driver
Information Center (DIC), your vehicle should be
taken in for service. For more information on
the DIC messages, seeDriver Information
Center (DIC) on page 269.
The StabiliTrak
®light
will ash on the
instrument panel cluster
when the system is
both on and activated.
You may also feel or hear the system working;
this is normal.

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.
505

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change your oil prior to a CHANGE ENGINE
OIL SOON message coming on, reset the system.
Always reset the engine oil life to 100% after
every oil change. It will not reset itself. To reset
the Engine Oil Life System, do the following:
1. Display the OIL LIFE REMAINING on the DIC.
If your vehicle does not have DIC buttons, the
vehicle must be in PARK (P) to access this
display. SeeDIC Operation and Displays (With
DIC Buttons) on page 270orDIC Operation
and Displays (Without DIC Buttons) on
page 277.
2. Press and hold the SET/RESET button on the
DIC, or the trip odometer reset stem if your
vehicle does not have DIC buttons, for more
than ve seconds. The oil life will change
to 100%.If the CHANGE ENGINE OIL SOON message
comes back on when you start your vehicle, the
Engine Oil Life System has not reset. Repeat
the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that
may be unhealthy for your skin and could
even cause cancer. Do not 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 dispose of 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 threat to the environment. If you
change your own oil, be sure to drain all the oil from
the lter before disposal. Never 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
used oil, ask your dealer, a service station, or a
local recycling center for help.

If the warning continues, pull over, stop, and park
your vehicle immediately.
If there is still no sign of steam and your vehicle
has an engine-driven cooling fan, push down
the accelerator until the engine speed is about
twice as fast as normal idle speed for at least
ve minutes while you are parked.
If there is still no sign of steam and your vehicle
has an electric cooling fan, idle the engine for
ve minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down. Also, see “Overheated Engine
Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode (V8 Engines Only)
If an overheated engine condition exists and
the REDUCED ENGINE POWER message
is displayed, an overheat protection mode which
alternates ring 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. Driving
extended miles (km) and/or 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
system. SeeEngine Oil (Gasoline Engine) on
page 502.
