Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key III+ is a passive theft
deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
If the engine does not start and the
security light comes on, the key may
have a damaged transponder. Turn
the ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. If the engine
still does not start with the other key,
the vehicle needs service. If the
vehicle does start, the first key may
be faulty. See your dealer or a
locksmith who can service the
PASS-Key III+ to have a new
key made.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to eight keys may be
programmed for the vehicle. This
procedure is for learning additional
keys only. If all the currently
programmed keys are lost or do not
operate, you must see your dealer
or a locksmith who can service
PASS-Key III+ to have keys made
and programmed to the system.
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank that is cut exactly as
the ignition key that operates the
system.
To program the new key:
1. Verify the new key has
1
stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder and start
the engine. If the engine will
not start, see your dealer for
service.

3. After the engine has started,turn the ignition off and remove
the key.
4. Insert the key to be programmed and turn the
ignition on within 10 seconds of
removing the previous key.
The security message will turn
off once the key has been
programmed. It may not be
apparent that the security
message went on due to how
quickly the key is programmed.
5. Repeat Steps 1–4 if additional keys are to be programmed.
If you lose or damage a
PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to have a new
key made.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.Exterior Mirrors
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.

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.

.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.

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 diagnosticmodule. For more information on the
airbag system, see
Airbag System
0 60.
The airbag readiness light comes on
for several seconds when the
vehicle is started. If the light does
not come on then, have it fixed
immediately.
{Warning
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.

with the airbag system. For
example, the front outboard
passenger frontal airbag could
inflate even though the airbag
on-off switch is turned off.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. SeeAirbag Readiness
Light 0105 for more information,
including important safety
information.
If the word ON or the on symbol is
lit, it means that the front outboard
passenger frontal airbag is enabled,
and may inflate. See Airbag On-Off
Switch 067 for more information,
including important safety
information.
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
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
0177.
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.

108 Instruments and Controls
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this
light to come on. This could
lead to costly repairs not covered
by the vehicle warranty. This
could also affect the vehicle’s
ability to pass an Emissions(Continued)
Caution (Continued)
Inspection/Maintenance test. See
Accessories and Modifications
0230.
If the light is flashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
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:
. A loose or missing fuel cap may
cause the light to come on. See
Filling the Tank 0208. 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 0206.
If the light remains on, see your
dealer.
