.It takes a little more, or less fuel to fill up
than the gauge indicated. For example,
the gauge may have indicated the tank
was half full, but it actually took a little
more, or less than half the tank's capacity
to fill the tank.
.The gauge moves a little while turning a
corner, speeding up or braking.
.The gauge takes a few seconds to
stabilize after the ignition is turned on
and goes back to empty when the
ignition is turned off.
Engine Oil Pressure Gauge
Uplevel Metric Shown, Base Level andMidlevel Similar
Uplevel English Shown, Base Level and
Midlevel Similar
The engine oil pressure gauge shows the
engine oil pressure in kPa (kilopascals)
or psi (pounds per square inch) when the
engine is running.
Oil pressure can vary with engine speed,
outside temperature, coolant temperature,
and oil viscosity.
On some models, the oil pump will vary
engine oil pressure according to engine
needs. Oil pressure may change quickly as
the engine speed or load varies. This is
normal. If the oil pressure warning light or
Driver Information Center (DIC) message indicates oil pressure outside the normal
operating range, check the vehicle's oil as
soon as possible.
See
Engine Oil 0311.
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
If the vehicle has a diesel engine, see the
Duramax diesel supplement.

Engine Coolant Temperature
Gauge
Uplevel Metric Shown, Base Level andMidlevel Similar
Uplevel English Shown, Base Level and Midlevel Similar
This gauge measures the temperature of the
vehicle's engine coolant.
While driving under normal operating
conditions, if the needle moves into the red
warning area, the engine is too hot. Pull off
the road, stop the vehicle, and turn off the
engine as soon as possible.
Voltmeter Gauge
Uplevel Shown, Base Level and Midlevel Similar
When the ignition is on, this gauge indicates
the battery voltage.
When the engine is running, this gauge
shows the condition of the charging system.
The gauge can transition from a higher to
lower or a lower to higher reading. This is
normal. If the vehicle is operating outside
the normal operating range, the charging
system light comes on. See Charging System
Light 0116. The voltmeter gauge may also
read lower when in fuel economy mode.
This is normal.

To help prevent damage, reduce vehicle
speed and avoid hard accelerations and
uphill grades. If towing a trailer, reduce the
amount of cargo being hauled as soon as
possible.
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:
.If fuel has been added to the vehicle
using the capless funnel adapter, make
sure that it has been removed. See
“Filling the Tank with a Portable Gas Can”
under Filling the Tank (Chassis Cab and
Box Delete Models) 0272 or
Filling the Tank (Pickup Models) 0271. The
diagnostic system can detect if the
adapter has been left installed in the
vehicle, allowing fuel to evaporate into
the atmosphere. A few driving trips with
the adapter removed may turn off the
light.
.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 0269.
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
0 303. 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.

Radio Reception
Unplug electronic devices from the accessory
power outlets if there is interference or
static in the radio.
FM
FM signals only reach about 16 to 65 km (10
to 40 mi). Although the radio has a built-in
electronic circuit that automatically works to
reduce interference, some static can occur,
especially around tall buildings or hills,
causing the sound to fade in and out.
AM
The range for most AM stations is greater
than for FM, especially at night. The longer
range can cause station frequencies to
interfere with each other. Static can also
occur when things like storms and power
lines interfere with radio reception. When
this happens, try reducing the treble on the
radio.

If your language supports it, try stating a
one-shot command, such as“Directions to
address province>.” Do not include the ZIP code
while stating the address during the
command. Another example of a one-shot
Destination Entry command is, “Directions to
Place of Interest at .” If these
commands do not work, try saying, “Take
me to Place of Interest” or“Find address”
and the system will walk you through by
asking additional questions.
Hybrid Speech Recognition
If equipped, this feature helps distinguish
words by using Internet-based information
along with the system’s voice recognition
database. This allows you to speak more
naturally when using voice recognition.
Using Voice Recognition
Voice recognition becomes available once
the system has been initialized. This begins
when the ignition is turned on. Initialization
may take a few moments.
1. Press
gon the steering wheel controls
to activate voice recognition.
2. The audio system mutes and the system plays a prompt. 3. Clearly speak one of the commands
described in this section.
A voice recognition system prompt can
be interrupted while it is playing by
pressing
gagain.
Once voice recognition is started, both the
infotainment display and instrument cluster
show the selections and visual dialog
content. These displays can be turned on or
off in the Tutorial Mode under Settings
0 184.
There are three voice prompt modes
supported:
.Informative verbal prompts: This type of
prompt will provide more information
regarding the supported actions.
.Short prompts: This type of prompt will
provide simple instructions about what
can be stated.
.Auto informative prompts: This type of
prompt plays during the first few speech
sessions, then automatically switches to
the short prompt after some experience
has been gained through using the
system.
If a command is not spoken, the voice
recognition system says a help prompt. Prompts and Infotainment Displays
While a voice recognition session is active,
there may be corresponding options
showing on the displays. A selection can be
made by manually touching the option,
or by speaking the number for the option to
select. Manual interaction in the voice
recognition session is permitted. Interaction
during a voice session may be completed
entirely using voice commands while some
manual commands may expedite a task. If a
selection is made using a manual control,
the voice recognition dialog will progress in
the same way as if the selection were made
using a voice command. Once the system
completes the task, or the session is
terminated, the voice recognition dialog
stops.
An example of this type of manual
intervention is touching an entry of a
displayed number list instead of speaking
the number associated with the entry
desired.
Canceling Voice Recognition
.Touch or say
“Cancel”or“Exit” to
terminate the voice recognition session
and show the display where voice
recognition was initiated.
