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,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to x 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 to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine 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, your GM dealer can prepare
the vehicle for inspection.
Oil Pressure Light
If you have low engine oil
pressure, this light will stay
on after you start your
engine, or come on when
you are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it xed immediately by
your GM dealer.

Average Fuel Economy
Press the information button until AVG ECONOMY
displays. This mode shows the approximate average
miles per gallon (mpg) or liters per 100 kilometers
(L/100 km). This number is calculated based on the
number of mpg (L/100 km) recorded since the last time
this menu item was reset. To reset AVG ECONOMY,
press and hold the set/reset button. The display
will return to zero.
Instantaneous Fuel Economy
Press the information button until INST ECONOMY
displays. This mode shows the current fuel economy
at a particular moment and will change frequently
as driving conditions change. This mode shows the
instantaneous fuel economy in miles per gallon (mpg)
or liters per 100 kilometers (L/100 km). Unlike average
fuel economy, this screen cannot be reset.
Battery
Press the information button until BATTERY displays.
This mode shows the current battery voltage.
If there is a problem with the battery charging system,
a DIC message will display. SeeDIC Warnings and
Messages on page 3-51for more information.Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal.
Oil Life
Press the information button until OIL LIFE displays.
This mode shows an estimate of the oil’s remaining
useful life. If you see OIL LIFE 99% on the display, that
means 99% of the current oil life remains. The engine
oil life system will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the LOW OIL
PRESSURE message will appear on the display.
You should change your oil as soon as possible. See
Engine Oil on page 5-13. In addition to the engine oil life
system monitoring the oil life, additional maintenance
is recommended in the Maintenance Schedule in
this manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.

LOW BRAKE FLUID
This message will display when the brake uid level is
low. Fill the brake master cylinder to the proper
level. SeeEngine Compartment Overview on page 5-12
for the location of the brake master cylinder reservoir.
Also, seeBrakes on page 5-33for proper uid level.
The brake system warning light will also appear on the
instrument panel cluster when this message appears
on the DIC. SeeBrake System Warning Light on
page 3-37.
This message will display and a chime will sound only
while the ignition is in RUN. Press any of the DIC
buttons to acknowledge this message and to clear it
from the screen.
This message will continue to display for two seconds
if it has not been acknowledged when the engine is
turned off. It will also re-display for two seconds if the
message has been acknowledged, but the condition still
exists when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on.
LOW FUEL
This message will display when your vehicle is low on
fuel. You should rell the tank as soon as possible.
SeeFuel Gage on page 3-44andFilling the Tank on
page 5-8for more information.
The message will display and a chime will sound while
the ignition is in RUN. Press any of the DIC buttons
to acknowledge this message and to clear it from
the screen.
If the condition still exists, the message will re-appear
when the engine is turned on.
LOW OIL PRESSURE
Notice:If the LOW OIL PRESSURE warning
message appears on the DIC display, stop the
vehicle immediately. Do not drive the vehicle until
the cause of the low oil pressure is corrected.
Severe engine damage can result from driving a
vehicle with low oil pressure. SeeEngine Oil
on page 5-13for more information.
This message will display when the vehicle’s engine oil
pressure is low. The oil pressure light will also appear
on the instrument panel cluster. SeeOil Pressure Light
on page 3-42.

Once you are moving on the freeway, make certain
you allow a reasonable following distance. Expect
to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit,
do not, under any circumstances, stop and back up.
Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer,
not to your sense of motion. After driving for any
distance at higher speeds, you may tend to think you
are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts in
GM dealerships all across North America. They will be
ready and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full?
Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to
the recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?

Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
