Reclining Seatbacks
{Warning
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the seat belts
cannot do their job.
The shoulder belt will not be against
your body. Instead, it will be in front of
you. In a crash, you could go into it,
receiving neck or other injuries.
The lap belt could go up over your
abdomen. The belt forces would be there,
not at your pelvic bones. This could cause
serious internal injuries.
For proper protection when the vehicle is
in motion, have the seatback upright.
Then sit well back in the seat and wear
the seat belt properly.
Do not have a seatback reclined if the
vehicle is moving.
Manual Reclining Seatbacks
{Warning
If either seatback is not locked, it could
move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on
the seatbacks to be sure they are locked.

Rear Seats
Rear Seat Reminder
If equipped, the message REAR SEAT
REMINDER LOOK IN REAR SEAT displays
under certain conditions indicating there
may be an item or passenger in the rear
seat. Check before exiting the vehicle.
This feature will activate when a second row
door is opened while the vehicle is on or up
to 10 minutes before the vehicle is turned
on. There will be an alert when the vehicle
is turned off. The alert does not directly
detect objects in the rear seat; instead,
under certain conditions, it detects when a
rear door is opened and closed, indicating
that there may be something in the
rear seat. The feature is active only once each time
the vehicle is turned on and off, and will
require reactivation by opening and closing
the second row doors. There may be an
alert even when there is nothing in the rear
seat; for example, if a child entered the
vehicle through the rear door and left the
vehicle without the vehicle being shut off.
The feature can be turned on or off. See
Vehicle Personalization
0109.
Folding the Seatback
Either side of the seatback can be folded for
more cargo space. Fold a seatback only
when the vehicle is not moving.
Caution
Folding a rear seat with the seat belts
still fastened may cause damage to the
seat or the seat belts. Always unbuckle
the seat belts and return them to their
normal stowed position before folding a
rear seat.

Seats and Restraints 41
To fold the seatback:
1. Pull the handle on top of the seatback tounlock it.
A tab near the seatback lever raises
when the seatback is unlocked.
2. Fold the seatback forward.
3. Repeat the steps to fold the other seatback, if desired.
Raising the Seatback
{Warning
If either seatback is not locked, it could
move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on
the seatbacks to be sure they are locked.
{Warning
A seat belt that is improperly routed, not
properly attached, or twisted will not
provide the protection needed in a crash.
The person wearing the belt could be
seriously injured. After raising the rear
seatback, always check to be sure that
the seat belts are properly routed and
attached, and are not twisted.
To raise a seatback: 1. Lift the seatback up and push it rearward to lock it in place.
A tab near the seatback lever retracts
when the seatback is locked in place.
2. Push and pull the top of the seatback to be sure it is locked into position. 3. Repeat the steps to raise the other
seatback, if necessary.
When the seat is not in use, it should be
kept in the upright, locked position.
Seat Belts
This section describes how to use seat belts
properly, and some things not to do.
{Warning
Do not let anyone ride where a seat belt
cannot be worn properly. In a crash,
if you or your passenger(s) are not
wearing seat belts, injuries can be much
worse than if you are wearing seat belts.
You can be seriously injured or killed by
hitting things inside the vehicle harder or
by being ejected from the vehicle. In
addition, anyone who is not buckled up
can strike other passengers in the vehicle.
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, passengers riding in these
areas are more likely to be seriously (Continued)

Warning (Continued)
injured or killed. Do not allow passengers
to ride in any area of the vehicle that is
not equipped with seats and seat belts.
Always wear a seat belt, and check that
all passenger(s) are restrained
properly too.
This vehicle has indicators as a reminder to
buckle the seat belts. See Seat Belt
Reminders 093.
Why Seat Belts Work
When riding in a vehicle, you travel as fast
as the vehicle does. If the vehicle stops
suddenly, you keep going until something
stops you. It could be the windshield, the
instrument panel, or the seat belts!
When you wear a seat belt, you and the
vehicle slow down together. There is more
time to stop because you stop over a longer
distance and, when worn properly, your
strongest bones take the forces from the
seat belts. That is why wearing seat belts
makes such good sense.
Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after a
crash if I am wearing a seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you canunbuckle and get out,
is much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work withseat belts —not instead
of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection. Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.
Buckle To Drive
If equipped, this feature prevents the vehicle
from shifting out of P (Park) when the driver
seat belt is not buckled. The Buckle to Drive
feature must be turned ON in the
infotainment system to work. See
Vehicle
Personalization 0109 and if equipped, Teen
Driver 0166. If the engine is running, the
driver seat belt is not buckled, and the brake
pedal is pressed with the vehicle in P (Park),
a message displays in the Driver Information
Center (DIC). Buckle the driver seat belt to
shift out of P (Park). Shifting from P (Park)
will be prevented once for each ignition
cycle.
For some fleet vehicles, the feature is
always ON and it cannot be turned OFF in
the infotainment system. Shifting from
P (Park) will be prevented each time the
above conditions exist.
On some models, Buckle to Drive may also
prevent shifting out of P (Park) if a front
passenger is unbuckled under similar
conditions. A message displays in the DIC.
Buckle the front passenger seat belt to shift

14583509) - 2021 - CRC - 1/8/21
Seats and Restraints 43
out of P (Park). This feature may not allow
the vehicle to shift out of P (Park) if an
object, such as a briefcase, handbag, grocery
bag, laptop, or other electronic device, is on
the front passenger seat. If this happens,
remove the object from the seat or buckle
the seat belt to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains unbuckled,
the DIC message will turn off after several
seconds and the vehicle can be shifted out
of P (Park). See“Seat Belts”and“Child
Restraints” in the Index for information
about the importance of proper
restraint use.
If the driver seat belt, and in some vehicles
the front passenger seat belt, is unbuckled
when driving, the seat belt reminder chime
and light(s) will come on. See Seat Belt
Reminders 093. This feature may not
function properly if the airbag readiness
light is on. See Airbag Readiness Light 094.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see Older Children058 or Infants and Young Children
060. Review
and follow the rules for children in addition
to the following rules.
It is very important for all occupants to
buckle up. Statistics show that unbelted
people are hurt more often in crashes than
those who are wearing seat belts.
There are important things to know about
wearing a seat belt properly.
.Sit up straight and always keep your feet
on the floor in front of you (if possible).
.Always use the correct buckle for your
seating position.
.Wear the lap part of the belt low and
snug on the hips, just touching the
thighs. In a crash, this applies force to the strong pelvic bones and you would be
less likely to slide under the lap belt.
If you slid under it, the belt would apply
force on your abdomen. This could cause
serious or even fatal injuries.
.Wear the shoulder belt over the shoulder
and across the chest. These parts of the
body are best able to take belt
restraining forces. The shoulder belt locks
if there is a sudden stop or crash.
{Warning
You can be seriously injured, or even
killed, by not wearing your seat belt
properly.

Buick E2UB-N Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583509) - 2021 - CRC - 1/8/21
44 Seats and Restraints
Never allow the lap or shoulder belt to
become loose or twisted.Never wear the shoulder belt under both
arms or behind your back.
Always use the correct buckle for your
seating position.
Never route the lap or shoulder belt over an
armrest.
{Warning
The seat belt can be pinched if it is
routed under plastic trim on the seat,
such as trim around the rear seatback
folding handle or side airbag. In a crash,
pinched seat belts might not be able to
provide adequate protection. Never allow
seat belts to be routed under plastic trim
pieces.
Lap-Shoulder Belt
All seating positions in the vehicle have a
lap-shoulder belt.

14583509) - 2021 - CRC - 1/8/21
Seats and Restraints 45
The following instructions explain how to
wear a lap-shoulder belt properly.1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how,
see “Seats” in the Index.
2. Pick up the latch plate and pull the belt
across you. Do not let it get twisted.
The lap-shoulder belt may lock if you
pull the belt across you very quickly.
If this happens, let the belt go back
slightly to unlock it. Then pull the belt
across you more slowly.
If the shoulder portion of a passenger
belt is pulled out all the way, the child
restraint locking feature may be engaged. See
Child Restraint Systems
0 62. If this occurs, let the belt go back
all the way and start again. If the
locking feature stays engaged after
letting the belt go back to stowed
position on the seat, move the seat
rearward or recline the seat until the
shoulder belt retractor lock releases.
Engaging the child restraint locking
feature in the front outboard seating
position may affect the passenger
sensing system. See Passenger Sensing
System 053.
3. Push the latch plate into the buckle until
it clicks. Pull up on the latch plate to make sure
it is secure. If the belt is not long
enough, see
Seat Belt Extender 047.
Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.
4. If equipped with a shoulder belt height adjuster, move it to the height that is
right for you. See “Shoulder Belt Height
Adjuster” later in this section for
instructions on use and important safety
information.5. To make the lap part tight, pull up on the shoulder belt.
