Tire Pressure Light
For vehicles with a tire pressure monitoring system, this
light comes on briefly when the engine is started. It
provides information about tire pressures and the Tire
Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC) on page 4-39for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. SeeIn ation - Tire Pressure on page 6-51for
more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about
a minute and stays on steady for the remainder of
the ignition cycle. This sequence repeats with every
ignition cycle. SeeTire Pressure Monitor Operation on
page 6-54for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It
ensures that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.

This can take several days of routine driving. If this
has been done and the vehicle still does not
pass the inspection for lack of OBD II system
readiness, your dealer/retailer can prepare
the vehicle for inspection.
Oil Pressure Light
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
This light comes on briefly while starting the engine. If it
does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
If the light comes on and stays on, it means that oil is
not flowing through the engine properly. The vehicle
could be low on oil and it might have some other system
problem.

this light and the vehicle’s
security system, see

Here are four things that some owners ask about.
These are normal and do not indicate a problem with
the fuel gage:
•At the service station, the gas pump shuts off
before the gage reads full.
•It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the fuel tank was half full, but it actually
took a little more or less than half the fuel tank’s
capacity to fill it.
•The indicator moves a little when while turning a
corner or speeding up.
•The gage goes back to empty when the ignition is
turned off.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
The DIC display gives you the status of many of your
vehicle’s systems. The DIC is also used to display driver
personalization menu modes and warning/status
messages. All messages will appear in the DIC display,
located at the bottom of the instrument panel cluster.The DIC buttons are
located on the left side of
the steering wheel.
INFO (Information):Press this button to scroll through
the vehicle information mode displays.
r(Reset):Press this button to reset some vehicle
information mode displays, select a personalization
menu mode setting, or acknowledge a warning
message.
Press and hold the information and reset buttons at the
same time for one second, then release the buttons
to enter the personalization menu. SeeDIC Vehicle

Gasoline Octane
If the vehicle has the 2.4L L4 engine (VIN Code 0), use
regular unleaded gasoline with a posted octane rating
of 87 or higher. If the octane rating is less than 87,
an audible knocking noise, commonly referred to
as spark knock, might be heard when driving. If this
occurs, use a gasoline rated at 87 octane or higher as
soon as possible. If heavy knocking is heard when
using gasoline rated at 87 octane or higher, the engine
needs service.
If the vehicle has the 3.6L V6 engine (VIN Code 7),
use regular unleaded gasoline with a posted octane
rating of 87 or higher. For best performance or trailer
towing, you could choose to use middle grade 89 octane
unleaded gasoline. If the octane rating is less than 87,
an audible knocking noise, commonly referred to as
spark knock, might be heard when driving. If this occurs,
use a gasoline rated at 87 octane or higher as soon
as possible. If heavy knocking is heard when using
gasoline rated at 87 octane or higher, the engine needs
service.
Gasoline Speci cations
At a minimum, gasoline should meet ASTM
specification D 4814 in the United States or
CAN/CGSB-3.5 or 3.511 in Canada. Some gasolines
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT).
We recommend against the use of gasolines
containing MMT. SeeAdditives on page 6-7for
additional information.
California Fuel
If the vehicle is certified to meet California Emissions
Standards, it is designed to operate on fuels that
meet California specifications. See the underhood
emission control label. If this fuel is not available
in states adopting California emissions standards, the
vehicle will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
might be affected. The malfunction indicator lamp
could turn on and the vehicle might fail a smog-check
test. SeeMalfunction Indicator Lamp on page 4-34.
If this occurs, return to your authorized dealer/retailer for
diagnosis. If it is determined that the condition is
caused by the type of fuel used, repairs might not be
covered by the vehicle warranty.

Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that help prevent
engine and fuel system deposits from forming, allowing
the emission control system to work properly. In
most cases, nothing should have to be added to the
fuel. However, some gasolines contain only the
minimum amount of additive required to meet U.S.
Environmental Protection Agency regulations. To help
keep fuel injectors and intake valves clean, or if the
vehicle experiences problems due to dirty injectors or
valves, look for gasoline that is advertised as TOP TIER
Detergent Gasoline.
For customers who do not use TOP TIER Detergent
Gasoline regularly, one bottle of GM Fuel System
Treatment PLUS, added to the fuel tank at every engine
oil change, can help clean deposits from fuel injectors
and intake valves. GM Fuel System Treatment PLUS is
the only gasoline additive recommended by General
Motors.
Also, your dealer/retailer has additives that will help
correct and prevent most deposit-related problems.Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available
in your area. We recommend that you use these
gasolines, if they comply with the specifications
described earlier. However, E85 (85% ethanol) and
other fuels containing more than 10% ethanol must not
be used in vehicles that were not designed for those
fuels.
Notice:This vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the
vehicle warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance of the
emission control system could be affected. The
malfunction indicator lamp might turn on. If this occurs,
return to your dealer/retailer for service.
