Head Restraints
Front Seats
The vehicle's front seats have
adjustable head restraints in the
outboard seating positions.
{Warning
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.
To raise or lower the head restraint,
press the button located on the side
of the head restraint, and pull up orpush the head restraint down, and
release the button. Pull and push on
the head restraint after the button is
released to make sure that it is
locked in place.
To adjust the head restraint forward
and rearward, press the button
located on the side facing of the
head restraint and move it forward
or rearward until the desired locking
position is reached. Try to move the
head restraint after the button is
released to make sure that it is
locked in place.
The front seat outboard head
restraints are not removable.
Rear Seats
The vehicle's rear seats have
adjustable head restraints in the
outboard seating positions.
The height of the head restraint can
be adjusted. Pull the head restraint
up to raise it. Try to move the head
restraint to make sure that it is
locked in place.

place.
Always adjust the head restraint so
that the top of the restraint is at the
same height as the top of the
occupant’s head.The rear outboard head restraints
are designed to be folded. The head
restraint can be folded backward to
allow for better visibility when the
rear seat is unoccupied. To fold the
head restraint, press the button on
the side of the head restraint.When an occupant is in the seat,
always return the head restraint to
the upright position. Pull the head
restraint up and push it backward
until it locks into place. Push and
pull on the head restraint to make
sure that it is locked.

Split Folding Seatbacks
Either side of the rear seatback can
be folded down for more cargo
space.
Manually Folding the
SeatbacksCaution
Folding a rear seat with the safety
belts still fastened may cause
damage to the seat or the safety
belts. Always unbuckle the safety
belts and return them to their
normal stowed position before
folding a rear seat.
Sliding Seatback
To fold a sliding seatback: 1. Place the front seatbacks in the upright position. See Reclining
Seatbacks 054.
2. Fold the rear seat head restraints. See Head Restraints
0 51.
3. Pull on the lever on the side of
the seatback to unlock it and
fold the seatback forward.
4. Verify the seat is locked in the folded position by pushing
down on the seatback.
5. Repeat the steps for the other seatback, if desired.
Automatically Folding the
Seatbacks
If equipped, to automatically fold the
seatback:
1. Place the front seatbacks in the upright position. See Reclining
Seatbacks 054. 2. Fold the rear seat head
restraints. See Head Restraints
0 51.
3. Pull the lever to activate the
automatic folding feature.
4. Verify the seat is locked in the folded position by pushing

belts during the early stages of a
moderate to severe frontal, near
frontal, or rear crash if the threshold
conditions for pretensioner
activation are met. Safety belt
pretensioners can also help tighten
the safety belts in a side crash or a
rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle's safety
belt system will need to be replaced.
SeeReplacing Safety Belt System
Parts after a Crash 067.
Do not sit on the outboard safety
belt while entering or exiting the
vehicle or at any time while sitting in
the seat. Sitting on the safety belt
can damage the webbing and
hardware.
Rear Safety Belt Comfort
Guides
Rear safety belt comfort guides may
provide added safety belt comfort
for older children who have
outgrown booster seats and for
some adults. When installed on a shoulder belt, the comfort guide
positions the belt away from the
neck and head.
Comfort guides are available
through your dealer for the rear
outboard seating positions.
Instructions are included with the
guide.
Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. 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.
To wear it, attach it to the regular

When Should an Airbag
Inflate?
This vehicle is equipped with
airbags. SeeAirbag System 068.
Airbags are designed to inflate if the
impact exceeds the specific airbag
system's deployment threshold.
Deployment thresholds are used to
predict how severe a crash is likely
to be in time for the airbags to
inflate and help restrain the
occupants. The vehicle has
electronic sensors that help the
airbag system determine the
severity of the impact. Deployment
thresholds can vary with specific
vehicle design.
Frontal airbags are designed to
inflate in moderate to severe frontal
or near frontal crashes to help
reduce the potential for severe
injuries, mainly to the driver's or
front outboard passenger's head
and chest.
Whether the frontal airbags will or
should inflate is not based primarily
on how fast the vehicle is traveling. It depends on what is hit, the
direction of the impact, and how
quickly the vehicle slows down.
Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or
moving, rigid or deformable, narrow
or wide.
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or many side impacts.
In addition, the vehicle has
advanced technology frontal
airbags. Advanced technology
frontal airbags adjust the restraint
according to crash severity or
occupant interaction.
The vehicle also has a seat position
sensor that enables the sensing
system to monitor the position of the
front outboard passenger seat. The
passenger seat position sensor and
the passenger safety belt buckle
provide information that is used to
adjust the deployment of the front
outboard passenger frontal airbag.Knee airbags are designed to inflate
in moderate to severe frontal or
near frontal impacts. Knee airbags
are not designed to inflate during
vehicle rollovers, in rear impacts,
or in many side impacts.
The passenger seat position sensor
and the passenger safety belt
buckle also provide information that
is used to determine if the
passenger knee airbag should
inflate.
Seat-mounted side impact airbags
are designed to inflate in moderate
to severe side crashes depending
on the location of the impact.
Seat-mounted side impact airbags
are not designed to inflate in frontal
impacts, near frontal impacts,
rollovers, or rear impacts.
A seat-mounted side impact airbag
is designed to inflate on the side of
the vehicle that is struck.
Roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location
of the impact. In addition, these
roof-rail airbags are designed to
inflate during a rollover or in a

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
10122659) - 2017 - crc - 11/16/16
Seats and Restraints 73
severe frontal impact. Roof-rail
airbags are not designed to inflate in
rear impacts. Both roof-rail airbags
will inflate when either side of the
vehicle is struck, if the sensing
system predicts that the vehicle is
about to roll over on its side, or in a
severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
vehicle damage or the repair costs.
What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out
of the cover. The inflator, the airbag,
and related hardware are all part of
the airbag module.
For airbag locations, seeWhere Are
the Airbags? 070.
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.
Airbags supplement the protection
provided by safety belts by
distributing the force of the impact
more evenly over the
occupant's body.
Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in the
outboard seating positions in the
first and second rows. The rollover
capable roof-rail airbags are
designed to help reduce the risk of
full or partial ejection in rollover
events, although no system can
prevent all such ejections. But airbags would not help in many
types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? 072.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See after
an Airbag Inflates?
After the frontal, knee, and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they inflate. Some components of
the airbag module may be hot for
several minutes. For location of the
airbags, see Where Are the
Airbags? 070.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not

Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light on the overhead console
when the vehicle is started.
United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, or the symbol for on and off will be visible. See
Passenger Airbag Status Indicator
0
121.
The passenger sensing system
turns off the front outboard
passenger frontal airbag and knee
airbag, under certain conditions. No
other airbag is affected by the
passenger sensing system.
The passenger sensing system
works with sensors that are part of
the front outboard passenger seat
and safety belt. The sensors are
designed to detect the presence of
a properly seated occupant and
determine if the front outboard
passenger frontal airbag and knee
airbag should be allowed to inflate
or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in a correct
child restraint for their weight
and size.
Whenever possible, children aged
12 and under should be secured in
a rear seating position. 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 inflates.
{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the passenger frontal
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
passenger frontal airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the front
outboard passenger airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag(s) are off.

in a child restraint. If a child restraint
has been installed and the on
indicator is lit:1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints (With
the Safety Belt in the Rear
Seat) 094 orSecuring Child
Restraints (With the Safety Belt
in the Front Seat) 096.
Make sure the safety belt
retractor is locked by pulling
the shoulder belt all the way
out of the retractor when
installing the child restraint,
even if the child restraint is
equipped with a safety belt
lock-off. When the retractor lock is set, the belt can be
tightened but not pulled out of
the retractor.
5. If, after reinstalling the child restraint and restarting the
vehicle, the on indicator is still
lit, turn the vehicle off. Then
slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback
is not pushing the child
restraint into the seat cushion.
Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. See Head Restraints
0 51.
6. Restart the vehicle.
The passenger sensing system
may or may not turn off the
airbags for a child in a child
restraint depending upon the
child’s size. It is better to
secure the child restraint in a
rear seat. Never put a rear-facing child restraint in the
front seat, even if the on
indicator is not lit.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat or that the child
restraint locking feature is engaged.
Use the following steps to allow the
system to detect that person and
enable the front outboard passenger
frontal airbag and knee airbag:
1. Turn the vehicle off.
