Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the next lane,
you could hit a vehicle that is
driving next to you. Check the
inside mirror or glance over your
shoulder before changing lanes.
If equipped, the lower portion of the
driver and passenger side mirror is
convex. A convex mirror's surface is
curved so more can be seen from
the driver seat. The convex mirror
can be adjusted manually to the
driver preferred position for better
vision.
Manual Mirrors
Adjust the mirrors by moving the
mirror up and down and left and
right. The mirrors can be manually folded
in or out.
On the lower portion of each mirror
is an auxiliary convex mirror.
A convex mirror's surface is curved
so you can see more from the driver
seat. The auxiliary convex mirrors
can be adjusted manually by
moving the mirror.
Trailer-Tow Mirrors
Vehicles with towing mirrors can be
adjusted manually for a clear view
of the objects behind you.

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 0333
and
Event Data Recorders 0333.
. 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.

items in the ashtray.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.

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
Information Center (DIC) 099.
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 0235.

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.This condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can be only driven for a
short time with the reading in either
warning zone. If it must be driven,
turn off all unnecessary
accessories.
Readings in either warning zone
indicate a possible problem in the
electrical system. Have the vehicle
serviced as soon as possible.
Seat Belt Reminders
Seat Belt Reminder Light
There is a seat belt reminder light
on the instrument cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their seat belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver seat belt is buckled,
neither the light nor the chime
comes on.
Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), the
pretensioners (if equipped), the
airbag modules, the wiring, and the
crash sensing and diagnostic
