You or others could be
injured if caught in the path
of the power liftgate. Make
sure there is no one in the
way of the liftgate as it is
opening and closing.
Caution
Driving with an open and
unsecured liftgate may
result in damage to the
power liftgate components.
The power liftgate switch is on

Falling Liftgate Detection
If the power liftgate
automatically closes after a
power opening cycle, it
indicates that the system is
reacting to excess weight on
the liftgate or a possible
support strut failure.
A repetitive chime will sound
while the falling liftgate
detection feature is operating.
Remove any excess weight.
If the liftgate continues to
automatically close after
opening, see your dealer for
service before using the
power liftgate.
Interfering with the power
liftgate motion or manually
closing the liftgate too quickly
after power opening may
resemble a support strut
failure. This could also activate
the falling liftgate detection
feature. Allow the liftgate to
complete its operation and
wait a few seconds before
manually closing the liftgate.Obstacle Detection
Features
If the liftgate encounters an
obstacle during a power open
or close cycle, the liftgate will
automatically reverse direction
and move a short distance
away from the obstacle. After
removing the obstruction, the
power liftgate operation can
be used again. If the liftgate
encounters multiple obstacles
on the same power cycle, the
power function will deactivate.
After removing the
obstructions, manually close
the liftgate. This will allow
normal power operation
functions to resume.
If the vehicle is locked while
the liftgate is closing, and an
obstacle is encountered that
prevents the liftgate from
completely closing, the horn
will sound as an alert that the
liftgate did not close.
Setting the 3/4 Mode
To change the position the
liftgate stops at when
opening:1. Select MAX or 3/4 mode and power open the
liftgate.
2. Stop the liftgate movement at the desired
height by pressing any
liftgate button. Manually
adjust the liftgate position
if needed.
3. Press and hold
lnext to
the pull cup on the bottom
of the liftgate until the turn
signals flash and a beep
sounds. This indicates the
setting has been recorded.
The liftgate cannot be set
below a minimum
programmable height. If there
is no light flash or sound, then
the height adjustment may be
too low.

Seat Belt Extender
If the vehicle's seat belt will
fasten around you, you should
use it.
But if a seat belt is not long
enough, your dealer will order
you an extender. Only a GM
dealer issued extender should
be used. When you go in to
order it, take the heaviest coat
you will wear, so the extender
will be long enough for you. To
help avoid personal injury, do
not let someone else use it,
and use it only for the seat it is
made to fit. The extender has
been designed for adults.
Never use it for securing child
restraints. For more
information on the proper use
and fit of seat belt extenders
see the instruction sheet that
comes with the extender.
Safety System Check
Periodically check the seat
belt reminder, seat belts,
buckles, latch plates,
retractors, shoulder beltheight adjusters (if equipped),
and seat belt anchorages to
make sure they are all in
working order. Look for any
other loose or damaged seat
belt system parts that might
keep a seat belt system from
performing properly. See your
dealer to have it repaired.
Torn, frayed, or twisted seat
belts may not protect you in a
crash. Torn or frayed seat
belts can rip apart under
impact forces. If a belt is torn
or frayed, have it replaced
immediately. If a belt is
twisted, it may be possible to
untwist by reversing the latch
plate on the webbing. If the
twist cannot be corrected, ask
your dealer to fix it.
Make sure the seat belt
reminder light is working. See
Seat Belt Reminders
0123.
Keep seat belts clean and dry.
See Seat Belt Care 064.
Seat Belt Care
Keep belts clean and dry. Seat belts should be properly
cared for and maintained.
Seat belt hardware should be
kept dry and free of dust or
debris. As necessary, exterior
hard surfaces and seat belt
webbing may be lightly
cleaned with mild soap and
water. Ensure there is not
excessive dust or debris in the
mechanism. If dust or debris
exists in the system please
see the dealer. Parts may
need to be replaced to ensure
proper functionality of the
system.
{Warning
Do not bleach or dye seat
belt webbing. It may severely
weaken the webbing. In a
crash, they might not be
able to provide adequate
protection. Clean and rinse
seat belt webbing only with
mild soap and lukewarm
water. Allow the webbing
to dry.

{Warning
For up to 10 seconds after
the vehicle 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
proper service procedures,
and make sure the person
performing work for you is
qualified to do so.
Adding Equipment to
the Airbag-Equipped
Vehicle
Adding accessories that
change the vehicle's frame,
bumper system, height, front
end, or side sheet metal may
keep the airbag system from
working properly.The operation of the airbag
system can also be affected
by changing, including
improperly repairing or
replacing, any parts of the
following:
.Airbag system, including
airbag modules, front or side
impact sensors, sensing and
diagnostic module, or airbag
wiring
.Front seats, including
stitching, seams or zippers
.Seat belts
.Steering wheel, instrument
panel, overhead console,
ceiling trim, or pillar
garnish trim
.Inner door seals, including
speakers
Your dealer and the service
manual have information about
the location of the airbag
modules and sensors, sensing
and diagnostic module, and
airbag wiring along with the
proper replacement
procedures. In addition, the vehicle has a
passenger sensing system for
the front outboard 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). See
Passenger Sensing System
