remote key is damaged, you may not be
able to start the vehicle. When trying to start the vehicle, the
security light comes on briefly when the
vehicle is turned on.
If the vehicle does not start and the security
light stays on, there is a problem with the

disarms or deactivates the theft-deterrent
system in the vehicle.

Head Restraints
The vehicle's front and rear seats have
adjustable head restraints in the outboard
seating positions.

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.

Chevrolet BOLT EV Owner Manual (GMNA-Localizing-U.S./Canada-
16404388) - 2023 - CRC - 3/7/22
26 Seats and Restraints
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.
Front Seats
The height of the head restraint can be
adjusted. To raise or lower the head
restraint, press the button located on the
side of the head restraint, and pull up or
push 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.
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 it is
locked in place.
To lower the head restraint, press the
button on the top of the seatback and push
the head restraint down. Try to move the
head restraint after the button is released to
make sure it is locked in place.If installing a child restraint in the rear seat,
see
“Securing a Child Restraint Designed for
the LATCH System” underLower Anchors
and Tethers for Children (LATCH System)
0 55.
Folding the Rear Head Restraint
The head restraint can be folded rearward 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.

36 Seats and Restraints
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. SeePassenger Sensing
System 044.
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 037.
Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.
4. To make the lap part tight, pull up on the shoulder belt.
To unlatch the belt, push the button on the
buckle. The belt should return to its stowed
position.
Always stow the seat belt slowly. If the seat
belt webbing returns quickly to the stowed
position, the retractor may lock and cannot
be pulled out. If this happens, pull the seat
belt straight out firmly to unlock the
webbing, and then release it. If the webbing
is still locked in the retractor, see your
dealer.
Before a door is closed, be sure the belt is
out of the way. If a door is slammed against
a seat belt, damage can occur to both the
seat belt and the vehicle.
Seat Belt Pretensioners
This vehicle has seat belt pretensioners for
the front outboard occupants. Although the
seat belt pretensioners cannot be seen, they
are part of the seat belt assembly. They can
help tighten the seat 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. Seat belt pretensioners can also help
tighten the seat belts in a side crash or a
rollover event.
