2009 GMC YUKON airbag off

The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to
one of the following conditions. If this occurs the
left indicator light on the mirror will ash.
A slow ash may indicate a loss of video signal, or
no video signal present during the reverse cycle.
A fast ash may indicate that the display has been
on for the maximum allowable time during a
reverse cycle, or the display has reached an Over
Temperature limit.
The fast ash conditions are used to protect the
video device from high temperature conditions. Once
conditions return to normal the device will reset and
the green indicator will stop ashing.
During any of these fault conditions, the display will be
blank and the indicator will continue to ash as long
as the vehicle is in R (Reverse) or until the conditions
return to normal.
Pressing and holding
zwhen the left indicator light is
ashing will turn off the video display along with the
left indicator light.

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light comes
on and stays on for
several seconds, then
ashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor the
light comes on.
Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
sounds for several seconds to remind the front passenger
to buckle their safety belt. This only occurs if the
passenger airbag is enabled. SeePassenger Sensing
System on page 1-90for more information. The
passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then ashes for several more.
3-36

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.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.
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 1-81.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
inate in a crash, or they could even inate
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 3-64
for more information.

Passenger Airbag Status Indicator
The vehicle has the passenger sensing system.
SeePassenger Sensing System on page 1-90for
important safety information. The overhead console has
a passenger airbag status indicator.
When the vehicle is started, the passenger airbag status
indicator will light ON and OFF, or the symbol for on and
off, for several seconds as a system check. If you are
using remote start to start the vehicle from a distance, if
equipped, you may not see the system check.Then, after several more seconds, the status indicator
will light either ON or OFF, or either the on or off symbol
to let you know the status of the right front passenger
frontal airbag.
If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag is enabled (may inate).
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger
frontal airbag.

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to the vehicle’s
three control systems. In the braking skid, the wheels are
not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
Remember: StabiliTrak
®helps avoid only the
acceleration skid. SeeStabiliTrak®System on page 4-6.
If the StabiliTrak®System is off, then an acceleration
skid is best handled by easing your foot off the
accelerator pedal.
If the vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
the vehicle may straighten out. Always be ready for
a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control more
limited.While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by shifting to
a lower gear. Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery until
the vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.
Off-Road Driving
Vehicles with four-wheel drive can be used for off-road
driving. Vehicles without four-wheel drive and vehicles
with 20-inch tire/wheel assemblies should not be driven
off-road except on a level, solid surface.
The airbag system is designed to work properly under
a wide range of conditions, including off-road usage.
Always wear your safety belt and observe safe driving
speeds, especially on rough terrain.
Drinking and driving can be very dangerous on any road
and this is certainly true for off-road driving. At the very
time you need special alertness and driving skills, your
reexes, perceptions, and judgment can be affected
by even a small amount of alcohol. You could have a
serious — or even fatal — accident if you drink and drive
or ride with a driver who has been drinking.
