Navigation System
The vehicle's navigation system
(if equipped) provides detailed maps
of most major freeways and roads.
After a destination has been set, the
system provides turn-by-turn
instructions for reaching the
destination. In addition, the system
can help locate a variety of points of
interest (POI), such as banks,
airports, restaurants, and more.
See the Navigation System manual
for more information.
Side Blind Zone
Alert (SBZA)
If available, this feature will alert you
to vehicles located in the vehicle's
side blind zone. When the system
detects a vehicle in the side blind
zone, an amber SBZA display will
light up in the corresponding outside
side mirror.
The system is enabled at every
vehicle startup. It can be disabled
through the Driver Information
Center (DIC).
If the message SIDE BLIND ZONE
SYSTEM UNAVAILABLE appears
on the DIC, the system has been
disabled because the sensor is
blocked and cannot detect vehicles
in the blind zone. The sensor may
be blocked by mud, dirt, snow, ice,
slush, or even heavy rainstorms.
This message may also activate
during heavy rain or due to road
spray. The vehicle does not need
service. See
Side Blind Zone Alert (SBZA)
on page 9‑63 for more information.Rear Vision
Camera (RVC)
If available, the rear vision camera
displays a view of the area behind
the vehicle when the vehicle is
shifted into R (Reverse). The
display will appear on either the
inside rearview mirror or navigation
screen, if equipped.
To clean the camera lens, located
above the license plate, rinse it with
water and wipe it with a soft cloth.

3-46 Seats and Restraints
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or in many side impacts.
In addition, the vehicle has
dual-stage frontal airbags.
Dual-stage airbags adjust the
restraint according to crash severity.
The 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
inflate at a level less than full
deployment. For more severe frontal
impacts, full deployment occurs.
The vehicle has a seat position
sensor. Vehicles with dual stage
airbags also have seat position
sensors which enable the sensing
system to monitor the position of the
driver seat and may or may not
monitor the position of the front
passenger seat.The seat position sensor provides
information that is used to determine
if the airbags should deploy at a
reduced level or at full deployment.
The vehicle may or may not have
seat‐mounted side impact airbags.
The vehicle has roof-rail airbags.
See
Airbag System on page 3‑41.
Seat‐mounted side impact airbags
and roof-rail airbags are intended to
inflate in moderate to severe side
crashes. In addition, these roof-rail
airbags are intended to inflate
during a rollover or in a severe
frontal impact. Seat‐mounted side
impact airbags and roof-rail airbags
will inflate if the crash severity is
above the system's designed
threshold level. The threshold level
can vary with specific vehicle
design. Roof-rail airbags are not
intended to inflate in rear impacts.
A seat‐mounted side impact airbag
is intended to deploy on the side of
the vehicle that is struck. Both
roof-rail airbags will deploy when
either side of the vehicle is struck or
if the sensing system predicts that
the vehicle is about to roll over, or in
a severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
damage to a vehicle or because of
what the repair costs were. For
frontal airbags, inflation is
determined by what the vehicle hits,
the angle of the impact, and how
quickly the vehicle slows down. For
seat‐mounted side impact and
roof-rail airbags, deployment is
determined by the location and
severity of the side impact. In a
rollover event, roof-rail airbag
deployment is determined by the
direction of the roll.

Black plate (50,1)Chevrolet Tahoe/Suburban Owner Manual - 2011
3-50 Seats and Restraints
The passenger sensing system will
turn off the right front passenger
frontal airbag under certain
conditions. The driver airbag,
seat‐mounted side impact airbags
(if equipped) and the roof-rail
airbags are not affected by the
passenger sensing system.
The passenger sensing system
works with sensors that are part of
the right front passenger 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 should be
enabled (may inflate) or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
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 the 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.
{WARNING
A child in a rear-facing child
restraint can be seriously injured
or killed if the right front
passenger airbag inflates. This is
because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front
passenger airbag inflates and the
passenger seat is in a forward
position.
(Continued)
WARNING (Continued)
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag is turned off.
Secure rear-facing child
restraints in a rear seat, even if
the airbag is 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.

Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information on page 13‑14.
{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow(Continued)
WARNING (Continued)
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto 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
sensing and diagnostic module,
steering wheel, instrument
panel, roof-rail airbag modules,
ceiling headliner or pillar garnish
trim, overhead console, front sensors, side impact sensors,
or airbag wiring can affect the
operation of the airbag system.
In addition, the vehicle may have
a passenger sensing system for
the right front passenger's
position, which includes sensors
that are part of the passenger's
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). See
Passenger Sensing System on
page 3‑49.
If you have any questions about
this, you should contact
Customer Assistance before you
modify your vehicle. The phone
numbers and addresses for
Customer Assistance are in

Satisfaction Procedure in this
manual. SeeCustomer
Satisfaction Procedure (U.S. and
Canada) on page 13‑1 or
Customer Satisfaction
Procedure (Mexico) on
page 13‑3.
If the vehicle has rollover
roof-rail airbags, see Different
Size Tires and Wheels on
page 10‑67 for additional
important information. Q: What if I added a snow plow?
Will it keep the airbags from
working properly?
A: We have designed our airbag
systems to work properly under
a wide range of conditions,
including snow plowing with
vehicles that have the optional
Snow Plow Prep Package
(RPO VYU). But do not change
or defeat the snow plow's
“tripping mechanism.” If you do,
it can damage your snow plow
and your vehicle, and it may
cause an airbag inflation. Q: Because I have a disability,
I have to get my vehicle
modified. How can I find out
whether this will affect my
airbag system?
A: If you have questions, call
Customer Assistance. The
phone numbers and addresses
for Customer Assistance are in
Step Two of the Customer
Satisfaction Procedure in this
manual. See Customer
Satisfaction Procedure (U.S. and
Canada) on page 13‑1 or
Customer Satisfaction
Procedure (Mexico) on
page 13‑3.
In addition, your dealer and the
service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.
