Information
This section provides a brief
overview about some of the
important features that may or may
not be on your specific vehicle.
For more detailed information, refer
to each of the features which can be
found later in this owner ’s manual.
Remote Keyless Entry
(RKE) System
The Remote Keyless Entry (RKE)
transmitter is used to remotely lock
and unlock the doors and it may
work up to 60 m (197 ft) away from
the vehicle.
Key Access RKE Transmitter

appropriate DIC message
displays.
. Press and release
gagain to
turn on both systems.
StabiliTrak will automatically turn on
if the vehicle exceeds 56 km/h
(35 mph). Traction control will
remain off.
See Traction Control/Electronic
Stability Control 0242.
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits
0212. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
0 349.
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure. See “Tire Fill Alert (If
Equipped)” underTire Pressure
Monitor Operation 0350.
Fuel (L83 5.3L V8 Engine)
Regular Unleaded Fuel
Use only Regular 87 octane —(R
+M)/2 —or higher unleaded
gasoline in your vehicle. TOP TIER
Detergent Gasoline is
recommended. Do not use gasoline
with an octane rating lower as it will
result in reduced performance and
lower fuel economy.
See Recommended Fuel (L86 6.2L
V8 Engine) 0269 orRecommended
Fuel (L83 5.3L V8 Engine) 0269.

Warning (Continued)
children or others could be caught
in the path of a closing window.
Do not leave children in a vehicle
with the ignition key or an RKE
transmitter.
{Warning
If the key is unintentionally
rotated while the vehicle is
running, the ignition could be(Continued)
Warning (Continued)
moved out of the RUN position.
This could be caused by heavy
items hanging from the key ring,
or by large or long items attached
to the key ring that could be
contacted by the driver or
steering wheel. If the ignition
moves out of the RUN position,
the engine will shut off, braking
and steering power assist may be
impacted, and airbags may not
deploy. To reduce the risk of
unintentional rotation of the
ignition key, do not change the
way the ignition key and Remote
Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
The ignition key and key rings, and
RKE transmitter, if equipped, are
designed to work together as a
system to reduce the risk of
unintentionally moving the key out
of the RUN position. The ignition
key has a small hole to allow attachment of the provided key ring.
It is important that any replacement
ignition keys have a small hole. See
your dealer if a replacement key is
required.
The combination and size of the
rings that came with your keys were
specifically selected for your
vehicle. The rings are connected to
the key like two links of a chain to
reduce the risk of unintentionally
moving the key out of the RUN
position. Do not add any additional
items to the ring attached to the
ignition key. Attach additional items
only to the second ring, and limit
added items to a few essential keys
or small, light items no larger than
an RKE transmitter.

32 Keys, Doors, and Windows
Interference from radio-frequency
identification (RFID) tags may
prevent the key from starting the
vehicle. Keep RFID tags away from
the key when starting the vehicle.
The key is used for the driver door,
ignition, and glove box.
If equipped with memory seats,
keys 1 and 2 are linked to seating
positions of memory 1 or 2. See
Memory Seats069.
Programming Keys to the
Vehicle
Follow these procedures to program
up to eight keys to the vehicle.
Programming with Two
Recognized Keys (Key
Vehicles Only)
To program a new key:
1. Insert the original, already programmed key in the ignition
and turn the ignition on without
starting the engine.
2. Turn the ignition off and remove the key. 3. Quickly, within five seconds,
insert the second original
already programmed key in the
ignition and turn the ignition on
without starting the engine.
4. Turn the ignition off and remove the key.
5. Insert the new key to be programmed, and within
five seconds, turn the ignition
on without starting the engine.
The security light will turn off
once the key has been
programmed.
6. Repeat Steps 1–5 if additional keys are to be programmed.
If a key is lost or damaged, see your
dealer to have a new key made.
Programming without Recognized
Keys (Key Vehicles Only)
Program a new key to the vehicle
when a recognized key is not
available. Canadian regulations
require that Canadian owners see
their dealer.

Keys, Doors, and Windows 33
If two currently recognized keys are
not available, follow this procedure
to program the first key.
This procedure will take
approximately 30 minutes to
complete for the first key. The
vehicle must be off and all of the
keys must be with you.1. Insert the new vehicle key into the ignition.
2. Turn the ignition on without starting the engine. The
security light will come on.
3. Wait 10 minutes until the security light turns off.
4. Turn the ignition off.
5. Repeat Steps 2–4 two more times. After the third time, turn
the ignition on; the key is
learned and all previously
known keys will no longer work
with the vehicle.
6. To learn the second key, turn the ignition off, insert the
second key to be learned, and
turn the ignition on without
starting the engine. After the two keys are learned,
remaining keys can be learned by
following the procedure in
“Programming with Two Recognized
Keys (Key Vehicles Only).”
The key has a bar-coded key tag
that the dealer or qualified locksmith
can use to make new keys. Store
this information in a safe place, not
in the vehicle.
See your dealer if a replacement
key or additional key is needed.
If it becomes difficult to turn a key,
inspect the key blade for debris.
Periodically clean with a brush
or pick.
If locked out of the vehicle, see
Roadside Assistance Program

With an active OnStar or connected
service plan, an OnStar Advisor
may remotely unlock the vehicle.
See OnStar Overview 0425.Remote Keyless Entry
(RKE) System
See Radio Frequency Statement
0 421.
If there is a decrease in the Remote
Keyless Entry (RKE) operating
range:
. Check the distance. The
transmitter may be too far from
the vehicle.
. Check the location. Other
vehicles or objects may be
blocking the signal.
. Check the transmitter's battery.
See “Battery Replacement” later
in this section.
. If the transmitter is still not
working correctly, see your
dealer or a qualified technician
for service.

56 Keys, Doors, and Windows
When trying to start the vehicle, the
security light comes on briefly when
the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. 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. It may be
necessary to check the fuse. See
Fuses and Circuit Breakers0329.
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. It is possible for the immobilizer
system to learn new or replacement
keys. Up to eight keys can be
programmed for the vehicle. To
program additional keys, see
Keys
(Keyless Access) 029 orKeys (Key
Access) 030. To program additional
transmitters, see your dealer.
Do not leave the key or device that
disarms or deactivates the vehicle
theft system in the vehicle.
See your dealer to get a new key
blank cut exactly as the ignition key
that operates the system.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 right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.
