2006 GMC Yukon, Yukon XL Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or in
different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the following
topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3
Warning Lights, Gages, and Indicators in Section 3

or the instrument panel... or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That is why
safety belts make such good sense.
1-30

{CAUTION:
Anyone who is up against, or very close to, any
airbag when it inates can be seriously injured
or killed. Airbags plus lap-shoulder belts offer
the best protection for adults, but not for young
children and infants. Neither the vehicle’s safety
belt system nor its airbag system is designed
for them. Young children and infants need the
protection that a child restraint system can
provide. Always secure children properly in
your vehicle. To read how, seeOlder Children
on page 1-47orInfants and Young Children
on page 1-50.
There is an airbag
readiness light on the
instrument panel cluster,
which shows the airbag
symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-38
for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
1-76

The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.If your vehicle has one, the driver’s side impact airbag
is in the side of the driver’s seatback closest to the door.
1-77

Your vehicle may or may not have a side impact airbag.
SeeAirbag System on page 1-74. Side impact airbags
are intended to inate in moderate to severe side
crashes. A side impact airbag will inate if the crash
severity is above the system’s designed “threshold
level.” The threshold level can vary with specic
vehicle design. Side impact airbags are not intended
to inate in frontal or near-frontal impacts, rollovers
or rear impacts. A side impact airbag is intended
to deploy on the side of the vehicle that is struck.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair
costs were. For frontal airbags, ination is determined
by what the vehicle hits, the angle of the impact,
and how quickly the vehicle slows down. For side
impact airbags, ination is determined by the location
and severity of the impact.
The airbag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving on page 4-16for tips on off-road driving.What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is in a crash.
The sensing system triggers a release of gas from
the inator, which inates the airbag. The inator,
the airbag and related hardware are all part of the
airbag modules. Frontal airbag modules are located
inside the steering wheel and instrument panel.
For seating positions with side impact airbags, there
are also airbag modules in the side of the seatbacks
closest to the door.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the
inside of the vehicle. The airbag supplements the
protection provided by safety belts. Airbags distribute
the force of the impact more evenly over the occupant’s
upper body, stopping the occupant more gradually.
But the frontal airbags would not help you in many
types of collisions, including rollovers, rear impacts,
and many side impacts, primarily because an
occupant’s motion is not toward the airbag.
1-80

Side impact airbags would not help you in many types
of collisions, including many frontal or near frontal
collisions, and rear impacts, primarily because an
occupant’s motion is not toward those airbags. Airbags
should never be regarded as anything more than a
supplement to safety belts, and then only in moderate to
severe frontal or near-frontal collisions for the frontal
airbags, and only in moderate to severe side collisions
for vehicles with a side impact airbag.
What Will You See After an
Airbag Inates?
After the airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module may
be hot for a short time. These components include
the steering wheel hub for the driver’s frontal airbag and
the instrument panel for the right front passenger’s
frontal airbag. For seating positions with side impact
airbags, the side of the seatback closest to the door may
be hot. The parts of the airbag that come into contact
with you may be warm, but not too hot to touch.There will be some smoke and dust coming from the
vents in the deated airbags. Airbag ination does
not prevent the driver from seeing out of the windshield
or being able to steer the vehicle, nor does it stop
people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is
safe to do so. If you have breathing problems
but cannot get out of the vehicle after an
airbag inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment,
you should seek medical attention.
1-81

If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat.
If this happens, turn the vehicle off and ask the person to
place the seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about
two minutes. This will allow the system to detect that
person and then enable the passenger’s airbag.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-38for more on this, including
important safety information.
