3-124 Instrument Panel
The system may be heard or felt
while it is working. This is normal and
does not mean there is a problem
with the vehicle. The system should
initialize before the vehicle reaches
20 mph (32 km/h). In some cases, it
may take approximately two miles
(3.2 km) 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,

GM6094M
Use only an oil that meets GM
Standard GM6094M.
SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use other
viscosity oils such as
SAE 20W-50.
American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst
symbol on the container. This
symbol indicates that the oil has
been certi ed by the American
Petroleum Institute (API).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 the
vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold,
where the temperature falls
below−20°F (−29°C), use either
an SAE 5W-30 synthetic oil or an
SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at
extremely low temperatures. Always
use an oil that meets the required
speci cation, GM6094M. See “What
Kind of Engine Oil to Use” for more
information.
Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
starburst symbol that meet GM
Standard GM6094M are all that is
needed for good performance and
engine protection.
Engine oil system ushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates 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 is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.
Service and Appearance Care 5-13
When the system has calculated
that oil life has been diminished,
it indicates that an oil change is
necessary. A CHANGE ENGINE OIL
SOON message comes on. Change
the oil as soon as possible within
the next 600 miles (1 000 km). It is
possible that, if driving under the best
conditions, the oil life system might
not indicate that an oil change is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and at
this time the system must be reset.
Your dealer/retailer has trained
service people who will perform this
work using genuine parts and reset
the system. It is also important to
check the oil regularly and keep it at
the proper level.If the system is ever reset
accidentally, the oil must be
changed at 3,000 miles (5 000 km)
since the last oil change. Remember
to reset the oil life system whenever
the oil is changed.
How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where the oil
is changed prior to a CHANGE
ENGINE OIL SOON message being
turned on, reset the system.If the vehicle does not have Driver
Information Center (DIC) buttons:
1. Turn the ignition to ON/RUN, with
the engine off. The vehicle must
be in P (Park) to access this
display. Press the trip odometer
reset stem until OIL LIFE
REMAINING displays.
2. Press and hold the trip
odometer reset stem until OIL
LIFE REMAINING shows 100%.
Three chimes sound and the
CHANGE ENGINE OIL SOON
message goes off.
3. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL
SOON message comes back on
when the vehicle is started, the
engine oil life system has not
reset. Repeat the procedure.

Used engine oil contains certain
elements that can 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. Recycle
it by taking it to a place that collects
used oil.
Engine Air Cleaner/Filter
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/ lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (80 000 km) interval.
SeeScheduled Maintenance on
page 6-3for more information. If you
are driving in dusty/dirty conditions,
inspect the lter at each engine oil
change.
SeeEngine Compartment Overview
on page 5-10for the location of
the engine air cleaner/ lter.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/ lter,
remove the lter from the vehicle and
lightly shake the lter (away from
vehicle) to release loose dust and
dirt. If the lter remains caked with
dirt, a new lter is required.

If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the
engine can get a little too hot when
the vehicle:
Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.3. If in a traffic jam, shift to
N (Neutral), otherwise, shift
to the highest gear while
driving —D (Drive) or L (Low).
If the temperature overheat gage is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue
to drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back
on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle
the engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating Mode”
next in this section.
Overheated
Engine Protection
Operating Mode
This emergency operating mode lets
the vehicle be driven to a safe place
in an emergency situation. If an
overheated engine condition exists,
an overheat protection mode which
alternates ring groups of cylinders
helps prevent engine damage. In this
mode, there is a signi cant loss in
power and engine performance.
The temperature gage indicates an
overheat condition exists. Driving
extended distances 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. See
Engine Oil on page 5-11.
Service and Appearance Care 5-23
Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers ash
their high-beam headlamps at
you (for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your
dealer/retailer for service.
