If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON light is on or not
working properly.Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.

2-81 Oil Warning Light
United States Canada
If you have a problem with your oil pressure, this light
may stay on after you start your engine, or come on
when you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in two other situations:
When the ignition is on but the engine is not running,
the light will come on as a test to show you it's
working. The light will go out when you turn the
ignition to RUN. If it doesn't come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.If you make a hard stop, the light may come on for a
moment. This is normal.
CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-82 Low Oil Level Light
The engine is equipped with
an oil level monitoring
system. When the ignition
key is turned to RUN, the
LOW OIL LEVEL light
will briefly flash.
If the light does not flash, have it fixed so it will be
ready to warn you if there is a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See ªEngine Oilº in the Index).
The oil level monitoring system only checks the oil level
during the brief period when the ignition key is between
RUN and START. It does not monitor engine oil level
when the engine is running. Additionally, an oil level
check is only performed if the engine has been turned
off for a considerable period of time, allowing the oil
normally in circulation to drain back into the oil pan.
Fuel Gage
United States Canada
The fuel gage tells you about how much fuel you have
left when the ignition is on. When the indicator nears
empty, you still have a little fuel left, but you should get
more soon.

NOTICE:
Although the HUD image appears to be near the
front of the vehicle, do not use it as a parking aid.
The HUD was not designed for that purpose.
If you try to use it that way, such as in a parking
lot, you may misjudge distance and run
into something.
When the HUD is on, the speedometer reading will be
displayed continually. The current radio station or CD
track number will only be displayed for three seconds
after the radio or CD track status changes. This will
happen whenever one of the radio controls is pressed,
either on the radio itself or on the optional steering
wheel controls.To adjust the HUD so you can see it properly:
1. Start your engine and turn the DIM thumbwheel to
the desired HUD image brightness.
2. Adjust your seat, if necessary, to a
comfortable position.
3. Press the top of the UP/DN switch until the HUD image
stops moving. Then press the bottom of the switch until
the image is as low as possible but in full view.
4. Turn the DIM thumbwheel down until the HUD
image is no brighter than necessary. To turn the HUD
off, turn the DIM thumbwheel all the way down.

2-89 Functions
: If one of the doors is ajar, this light will
appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the
system indicates that it's time for an oil change. The
system predicts remaining oil life using inputs from
length of drives, coolant temperature, engine rpm and
vehicle speed. It alerts you to change the oil on a
schedule consistent with the vehicle's driving
conditions. After changing the oil, the system must be
reset. See ªHow to Reset the GM Oil Life Systemº in
the Index.
LOW: This light will come on when the ignition is
on and the fluid in the washer fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.LOW TRAC: This light will come on when the traction
control system is limiting wheel spin. See ªTraction
Control Systemº or ªLow Traction Lightº in the Index.
TRAC OFF: This light lets you know that the traction
control system has been disabled and will not limit
wheel spin. See ªEnhanced Traction System Warning
Lightº or ªLow Traction Lightº in the Index.
TRAC: If the vehicle has the traction control system,
you will have a disable switch on the far right side of the
DIC. The traction control system is automatically
activated when you turn the ignition on. This switch will
activate/deactivate the traction control system. If you
need to disable the system, such as when you are stuck
and are rocking the vehicle back and forth, push this
button. See ªStuck: In Sand, Mud, Ice or Snowº in
the Index.
