inflate. The feature may also
activate, without airbag inflation,
after an event that exceeds a
predetermined threshold. After
turning the ignition off and then on
again, the fuel system will return to
normal operation; the doors can be
locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as
normal.
{Warning
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.(Continued)
Warning (Continued)
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
. Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts. .
The vehicle has a crash
sensing and diagnostic
module which records
information after a crash. See
Vehicle Data Recording and
Privacy 0331 and
Event Data Recorders 0332.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Airbag On-Off Switch
If the instrument panel has one of
the switches pictured in the
following illustrations, the vehicle
has an airbag on-off switch that you
can use to manually turn on or off
the front outboard passenger airbag.
No other airbag is affected by the
airbag on-off switch.

{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.

If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
Speedometer
The speedometer shows the vehicle
speed in kilometers per hour (km/h)
and miles per hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Trip Odometer
The trip odometer shows how far
the vehicle has been driven since
the trip odometer was last reset.
The trip odometer is accessed and
reset through the Driver Information
Center (DIC). SeeDriver

Fuel Gauge
Metric
English The fuel gauge, when the ignition is
on, indicates how much fuel is left in
the vehicle fuel tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
The gauge first indicates empty
before the vehicle is out of fuel, and
the fuel tank should be
refueled soon.
Listed are four situations customers
might experience with the fuel
gauge. None of these indicate a
problem with the fuel gauge:
.
At the gas station, the fuel pump
shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the fuel 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 or speeding up.

.The gauge does not go back to
empty when the ignition is
turned off.
If the vehicle has a diesel engine,
see the Duramax diesel
supplement.
Engine Oil Pressure
Gauge
Metric
English
The oil pressure gauge shows the
engine oil pressure in psi (pounds
per square inch) or kPa (kilopascals)
when the engine is running.
Oil pressure may vary with engine
speed, outside temperature and oil
viscosity, but readings above the
low pressure zone indicate the
normal operating range.
A reading in the low pressure zone
may be caused by a dangerously
low oil level or other problem
causing low oil pressure.
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.

Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the engine
coolant temperature.
It also provides an indicator of how
hard the vehicle is working. During a
majority of the operation, the gauge
will read 100 °C (210 °F) or less.
If the vehicle is pulling a load or
going up hills, it is normal for the
temperature to fluctuate and
approach the 122 °C (250 °F) mark.
If the gauge reaches the 125 °C
(260 °F) mark, it indicates that the
cooling system is working beyond
its capacity.
See Engine Overheating 0234.
Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts.
When the engine is running, the
gauge shows the condition of the
charging system. Readings between
the low and high warning zones
indicate the normal operating range.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
at an idle for an extended period.

Charging System Light
This light comes on briefly when the
ignition key is turned to START, 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.
The light should go out once the
engine starts. If it stays on,
or comes on while driving, there
could be a problem with the
charging system. A charging system
message in the Driver Information
Center (DIC) can also appear. This
light could indicate that there are
problems with a generator drive belt,
or that there is an electrical
problem. Have it checked right
away. If the vehicle must be driven a
short distance with the light on, turn
off accessories, such as the radio
and air conditioner.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is on
and the engine is not running. See
Ignition Positions 0162.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.

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. SeeAdd-On
Electrical Equipment 0212. 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.
MetricEnglish
This light should come on briefly
when the vehicle is turned on. If it
does not come on then, have it fixed
so it will be ready to warn you if
there is a problem.
When the ignition is on, the brake
system warning light also comes on
when the parking brake is set. See
Parking Brake 0176 for more
information. The light stays on if the
parking brake does not fully release.
If it stays on after the parking brake
is fully released, it means the
vehicle has a brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal might go closer to the
