2007 GMC YUKON light

{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. See
Airbag Readiness Light on page 229for
more on this, including important safety
information.Aftermarket equipment, such as seat covers, can
affect how well the passenger sensing system
operates. You may want to consider not using seat
covers or other aftermarket equipment if your
vehicle has the passenger sensing system. See
Adding Equipment to Your Airbag-Equipped
Vehicle on page 107for more information about
modications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 530for more
information.
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.Also look for any opened or broken airbag covers,
and have them repaired or replaced. The airbag
system does not need regular maintenance.
Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
or the side impact airbag covering on the
ceiling near the side windows, the airbag may
not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel
for the right front passenger’s airbag, or
side impact airbag module and ceiling covering
for roof-mounted rollover airbags. Do not
open or break the airbag coverings.
108

If an airbag inates, you will need to replace
airbag system parts. See the part on the airbag
system earlier in this section.
If the frontal airbags inate you will also need to
replace the driver and front passenger’s safety belt
retractor assembly. Be sure to do so. Then the
new retractor assembly will be there to help protect
you in a collision.After a crash you may need to replace the driver
and front passenger’s safety belt retractor
assemblies, even if the frontal airbags have not
deployed. The driver and front passenger’s safety
belt retractor assemblies contain the safety belt
pretensioners. Have your safety belt pretensioners
checked if your vehicle has been in a collision,
or if your airbag readiness light stays on after you
start your vehicle or while you are driving. See
Airbag Readiness Light on page 229.

Remote start can be extended one time.
When you enter the vehicle during a remote start,
and the engine is still running, turn the key to

Obstacle Detection Features
If the liftgate encounters an obstacle during a
power open or close cycle, a warning chime will
sound and the liftgate will automatically reverse
direction to the full closed or open position.
After removing the obstruction, the liftgate may be
power opened or closed normally. If the liftgate
encounters multiple obstacles on the same power
cycle, the power function will deactivate, and
the liftgate will switch to manual operation. The
REAR ACCESS OPEN warning message in
the Driver Information Center (DIC) will indicate
that the liftgate is open. After removing the
obstructions, manually open the liftgate to the full
open position or close the liftgate to the fully
closed and latched position. The liftgate will now
resume normal power operation.
Your vehicle has pinch sensors located on the
side edges of the liftgate. If an object is caught
between the liftgate and the vehicle body and
presses against this sensor, the liftgate will reverse
direction and open fully. The liftgate will remain
open until it is activated again or closed manually.
