When Should an Airbag In ate?
Frontal airbags are designed to in ate in moderate to
severe frontal or near-frontal crashes to help reduce the
potential for severe injuries mainly to the driver’s or
right front passenger’s head and chest. However, they
are only designed to in ate if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash is
likely to be in time for the airbags to in ate and
help restrain the occupants.
Whether your frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact,
and how quickly your vehicle slows down.
Frontal airbags may in ate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could in ate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could in ate at a different crash speed than
if the vehicle hits an object that does not deform.
If the vehicle hits a narrow object (like a pole), the
airbags could in ate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle, the
airbags could in ate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with speci c vehicle design.
In addition, your vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags in ate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
Frontal airbags are not intended to in ate during
vehicle rollovers, rear impacts, or in many side impacts.
The vehicle may or may not have seat-mounted side
impact airbags. SeeAirbag System on page 1-77.
Seat-mounted side impact airbags are intended to in ate
in moderate to severe side crashes. Seat-mounted
side impact airbags will in ate if the crash severity is
above the system’s designed threshold level. The
threshold level can vary with speci c vehicle design.

The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine if the right
front passenger frontal airbag and seat-mounted
side impact airbag (if equipped) should be enabled
(may in ate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on your sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag in ates. This is because the
back of the rear-facing child restraint would be
very close to the in ating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
in ates and the passenger seat is in a forward
position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped),
no system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag(s) are off.
Secure rear-facing child restraints in a rear seat,
even if the airbag(s) are off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint
in a rear seat.

{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
in ate during improper service. You can be injured
if you are close to an airbag when it in ates. 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 quali ed to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensingand diagnostic module, steering wheel, instrument
panel, front sensors, or airbag wiring can affect
the operation of the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front passenger position, which
includes sensors that are part of the passenger seat.
The passenger sensing system may not operate
properly if the original seat trim is replaced with
non-GM covers, upholstery or trim, or with GM
covers, upholstery or trim designed for a different
vehicle. Any object, such as an aftermarket seat
heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could also
interfere with the operation of the passenger sensing
system. This could either prevent proper deployment
of the passenger airbag(s) or prevent the passenger
sensing system from properly turning off the
passenger airbag(s). SeePassenger Sensing
System on page 1-85.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses for

sensing and diagnostic module and airbag wiring.
Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
If the vehicle has the built-in child restraint, also
periodically check the harness straps, latch plates,
buckle, clip, child head restraint and anchorages are
working properly.Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing
its job. See your dealer/retailer to have it repaired. Torn
or frayed safety belts may not protect you in a crash.
They can rip apart under impact forces. If a belt is torn
or frayed, get a new one right away.
If the vehicle has the built-in child restraint, torn or
frayed harness straps can rip apart under impact forces
just like torn or frayed safety belts can. They may not
protect a child in a crash. If a harness strap is torn
or frayed, get a new harness right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders on page 3-32for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts and Built-in Child Restraint Harness on page 5-92
for more information.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 3-33for more information.

Warm-Up Shift
Your vehicle has a computer controlled transmission
designed to warm up the engine faster when the outside
temperature is 35°F (2°C) or colder. You may notice
that the transmission will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly. See
Climate Control System on page 3-22andDual
Climate Control System on page 3-25for more
information.
THIRD (3):This position is also used for normal driving.
It reduces vehicle speed more than DRIVE (D) without
using your brakes. You might choose THIRD (3) instead
of DRIVE (D) when driving on hilly, winding roads,
when towing a trailer, so there is less shifting between
gears and when going down a steep hill.
SECOND (2):This position reduces vehicle speed more
than DRIVE (D) without using your brakes. You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you would
also want to use your brakes off and on.Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transmission. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of SECOND (2).
Notice:If your vehicle seems to start up rather
slowly, or if it seems not to shift gears as you go
faster, something may be wrong with a transmission
system sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens, have
your vehicle serviced right away. Until then, you can
use SECOND (2) when you are driving less than
35 mph (55 km/h) and THIRD (3) for higher speeds.
FIRST (1):This position reduces vehicle speed even
more than SECOND (2) without using your brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is put in FIRST (1) while the
vehicle is moving forward, the transmission will not shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.

mirrors. See “Rear Window Defogger” underClimate
Control System on page 3-22.
Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
If the vehicle has the URPA system, it helps you park
easier and avoid other vehicles while in R (Reverse). It
operates at speeds less than 3 mph (5 km/h). It can
determine how close objects are to the rear bumper, up
to 5 feet (1.5 m) behind the vehicle. The distance
sensors are located on the rear bumper.
{CAUTION:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
objects that are below the bumper,
underneath the vehicle, or if they are too
close or far from the vehicle
children, pedestrians, bicyclists, or pets.
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle’s mirrors.
2-44
Page 144 of 464
URPA can be turned off by
pressing the rear park aid
disable switch located
in the overhead console
switchbank.
While the system is disabled, an indicator light will be lit
on the switch. You will not see any lights on the rear
display if the switch is in the off position.When the System Does Not Seem to
Work Properly
The driver disabled the system.
The ultrasonic sensors are not clean, a red URPA
display light may illuminate when the vehicle is in
R (Reverse). Keep the rear bumper free of
mud, dirt, snow, ice and slush. For cleaning
instructions, seeWashing Your Vehicle on
page 5-93.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the liftgate during the
last drive cycle, the red light may illuminate.
Once the attached object is removed, URPA will
return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take the vehicle to your
dealer/retailer.

Wiper Activated Headlamps
For vehicles with this feature, the headlamps and
parking lamps are automatically activated after the
windshield wipers have been in use for about 30 seconds
and when all of the following conditions are met.
The exterior lamp control is in AUTO.
The headlamps have not already been activated by
automatic lighting.
The automatic lighting feature has not been disabled
using the exterior lamp control.
SeeExterior Lamps on page 3-13for additional
information.
If the wipers are activated for over 30 seconds and the
exterior lamp control is in the parking lamps position, or
the automatic lighting feature has been disabled using
the exterior lamp control, a HEADLAMPS SUGGESTED
message appears on the Driver Information Center, if
equipped.
Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. Fully functional Daytime Running Lamps are
required on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered. The DRL
system makes the front turn signal lamps come on in
daylight when the following conditions are met:
The ignition is on.
The exterior lamps control is off.
When the DRL are on, only the front turn signal lamps
will be on. The instrument panel will not be lit up.
The exterior lamps automatically switch from DRL to
regular headlamps depending on the darkness of
the surroundings.
If vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes approximately
30 seconds for the automatic headlamp system to
change to DRL if it is light outside. During that delay, the
instrument panel cluster may not be as bright as usual.
Make sure the instrument panel brightness control is in
the full bright position. SeeInstrument Panel Brightness
on page 3-15.

Power Outlet 115 Volt Alternating
Current
The vehicle may have a power outlet that can be used
to plug in electrical equipment that uses a maximum
limit of 150 watts.
The power outlet is located behind the third row seats
on the passenger’s side rear quarter trim panel.
An indicator light on the outlet turns on to show it is in
use. The light comes on when the ignition is in ON/RUN
and equipment requiring less than 150 watts is
plugged into the outlet, and no system fault is detected.The indicator light does not come on when the
ignition is in LOCK/OFF or if no equipment is
plugged into the outlet.
If you try to connect equipment using more than
150 watts or a system fault is detected, a protection
circuit shuts off the power supply and the indicator light
turns off. To reset the circuit, unplug the item and
plug it back in or turn the Remote Accessory Power
(RAP) off and then back on. SeeRetained Accessory
Power (RAP) on page 2-32. The power restarts
when equipment using 150 watts or less is plugged
into the outlet and a system fault is not detected.
The power outlet is not designed for the following
electrical equipment and may not work properly if these
items are plugged into the power outlet:
Equipment with high initial peak wattage such as:
compressor-driven refrigerators and electric
power tools.
Other equipment requiring an extremely stable
power supply such as: microcomputer-controlled
electric blankets, touch sensor lamps, etc.

This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the airbag
modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 1-77.The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.
{CAUTION:
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
in ate in a crash, or they could even in ate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 3-51
for more information.
