If the light continues to flash, find a safe
place to park. Turn the vehicle off and wait
at least 10 seconds before restarting the
engine. If the light is still flashing, follow
the previous guidelines and see your dealer
for service as soon as possible.
If the light is on steady :A malfunction has
been detected. Diagnosis and service may be
required.
Check the following:
.A loose or missing fuel cap may cause
the light to come on. See Filling the Tank
0 158. A few driving trips with the cap
properly installed may turn the light off.
.Poor fuel quality can cause inefficient
engine operation and poor driveability,
which may go away once the engine is
warmed up. If this occurs, change the fuel
brand. It may require at least one full
tank of the proper fuel to turn the light
off. See Recommended Fuel 0158.
If the light remains on, see your dealer.
Emissions Inspection and Maintenance
Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument panel to
the left of the steering wheel. Connecting
devices that are not used to perform an
Emissions Inspection/Maintenance test or to
service the vehicle may affect vehicle
operation. See Add-On Electrical Equipment
0 176. See your dealer if assistance is
needed.
The vehicle may not pass inspection if:
.The light is on when the engine is
running.
.The light does not come on when the
ignition is on while the engine is off.
.Critical emission control systems have not
been completely diagnosed. If this
happens, the vehicle would not be ready
for inspection and might require
several days of routine driving before the
system is ready for inspection. This can
happen if the 12-volt battery has recently
been replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not pass
or cannot be made ready for the test.
Brake System Warning Light
The vehicle brake system consists of two
hydraulic circuits. If one circuit is not
working, the remaining circuit can still work
to stop the vehicle. For normal braking
performance, both circuits need to be
working.
If the warning light comes on, there could
be a brake problem. Have the brake system
inspected right away.

Information Displays
Driver Information Center (DIC)
This vehicle has a DIC.
All messages will appear in the DIC display
at the bottom of the instrument cluster.
The DIC comes on when the ignition is on.
After a short delay, the DIC will display the
information that was last displayed before
the engine was turned off. The DIC displays trip, fuel, and vehicle
system information, and warning messages
if a system problem is detected.
If the vehicle has these features, the DIC
also displays the compass direction and the
outside air temperature when viewing the
trip and fuel information. The compass
direction appears on the top right corner of
the DIC display. The outside air temperature
automatically appears in the bottom right
corner of the DIC display. If there is a
problem with the system that controls the
temperature display, the numbers will be
replaced with dashes. If this occurs, have the
vehicle serviced by your dealer.
If the vehicle has a diesel engine, see the
Duramax diesel supplement.
DIC Operation and Displays
The DIC has different displays which can be
accessed by pressing the DIC buttons on the
instrument panel, next to the instrument

functional DRL are required on all vehicles
first sold in Canada.
The DRL system comes on in daylight when
the following conditions are met:
.The ignition is on.
.The exterior lamp control is in the AUTO
position.
.The shift lever is not in P (Park).
.The light sensor determines it is daytime.
When the DRL are on, the taillamps,
sidemarker, instrument panel lights, and
other lamps will not be on.

92 Lighting
The vehicle has a light sensor on the top of
the instrument panel. Do not cover the
sensor; otherwise the system will come on
whenever the ignition is on.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
There is a delay in the transition between
the daytime and nighttime operation of the
Daytime Running Lamps (DRL) and the
automatic headlamp system so that driving
under bridges or bright overhead street
lights does not affect the system. The DRL
and automatic headlamp system are only
affected when the light sensor sees a
change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. Once the vehicle leaves the
garage, it takes approximately 30 seconds
for the automatic headlamp system to
change to DRL if it is light outside. During
that delay, the instrument cluster may not
be as bright as usual. Make sure the
instrument panel brightness control is in the
full bright position. SeeInstrument Panel
Illumination Control 093. To idle the vehicle with the automatic
headlamp system off, turn the control off.
The headlamps will also stay on after
exiting the vehicle. This feature may be
programmable. See
Vehicle Personalization
0 86.
If the feature is not programmable, exit
lighting is automatic. When it is dark
enough outside, the exterior lamps remain
on for 30 seconds after the ignition is
turned off.
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on, and the
exterior lamp control is in AUTO, the
headlamps, parking lamps, and other
exterior lamps come on. The transition time
for the lamps coming on varies based on
wiper speed. When the wipers are not
operating, these lamps turn off. Move the
exterior lamp control to
Por;to
disable this feature.

Turn and Lane-Change Signals
G:An arrow on the instrument cluster
flashes in the direction of the turn or lane
change.
To signal a turn, move the lever all the way
up or down.
To signal a lane change, raise or lower the
