How Airbags Work
Airbags inflate when sensors detect an impact
that exceeds deployment thresholds. These
thresholds are designed to predict the severity
of a crash in time for the airbags to help
protect the vehicle's occupants. Airbags
inflate instantly with considerable force
accompanied by a loud noise. The inflated
bag, together with the seat belts, limits
movement of occupants to reduce the risk of
injury.
Front airbags are not ordinarily designed to
inflate in rear collisions, rollovers, side
collisions and when braking heavily or driving
over bumps and potholes. Likewise, front
airbags may not inflate in all frontal collisions,
such as minor front collisions, underride
collisions, or minor impacts with narrow
objects (such as posts or poles). Significant
superficial damage can occur to the vehicle
without the airbags inflating and, conversely, a
relatively small amount of structural damage
can cause airbags to inflate. Therefore, the
external appearance of the vehicle after a
collision does not represent whether or not
the front airbags should have inflated.
Warning: Before modifying your vehicle
to accommodate a person with
disabilities in a way that may aect the
airbag system, contact Tesla.
Types of Airbags
Model Y has the following types of airbags:
• Front airbags: The front airbags are
designed to reduce injuries if larger
children or adults are riding in the front
seats. Follow all warnings and instructions
related to seating a child on the front
passenger seat (if permitted in your
market region). See Child Safety Seats on
page 35.
• Knee airbags: Knee airbags and the front
airbags work together. The knee airbags
limit the forward motion of the front seat
occupants by restricting leg movement,
thereby positioning the occupants so that
the front airbags work more eectively.
• Seat-mounted side airbags: A seat-
mounted side airbag in the front seats
helps protect the pelvis and the thorax
region of the torso. The seat-mounted
side airbags on both the impacted and
non-impacted side of the vehicle will
inflate in the event of severe side impact
or severe oset frontal impact.
• Curtain airbags: Curtain airbags help
protect the head. Curtain airbags on both
the impacted and non-impacted side of
the vehicle will inflate only if a severe side
impact occurs, or if the vehicle rolls over.
