Seat Belts
Warning: Ensure that the seat belt is
positioned correctly and that the
shoulder anchor is locked into position
before driving. Riding in a moving vehicle
with the seat belt positioned incorrectly
or with the shoulder anchor not locked
into position can reduce the effectiveness
of the seat belt in a collision.
To Release a Belt
Hold the belt near the buckle to prevent the
belt from retracting too quickly, then press the
button on the buckle. The belt retracts
automatically. Ensure there is no obstruction
that prevents the belt from fully retracting.
The belt should not hang loose. If a seat belt
does not fully retract, contact Tesla.
Wearing Seat Belts When Pregnant
Do not put the lap or shoulder sections of the
seat belt over the abdominal area. Wear the
lap section of the belt as low as possible
across the hips, not the waist. Position the
shoulder portion of the belt between the
breasts and to the side of the abdomen.
Consult your doctor for specific guidance.
Warning: Never place anything between
you and the seat belt to cushion the
impact in the event of a collision.

Seat Belt Pre-tensioners
The front seat belts are equipped with
pre‑tensioners that work in conjunction with
the airbags in a severe frontal collision. The
pre‑tensioners automatically retract both the
seat belt anchor and the seat belt webbing,
reducing slack in both the lap and diagonal
portions of the belts, resulting in reduced
forward movement of the occupant.
The rear outboard seats are equipped with
shoulder pre-tensioners to retract the seat
belt webbing to reduce forward movement of
the occupant.
If the pre-tensioners and airbags did not
activate in an impact, this does not mean they
malfunctioned. It usually means that the
strength or type of force needed to activate
them was not present.
Warning: Once the seat belt pre-
tensioners have been activated, they must
be replaced. After any collision, have the
airbags, seat belt pre-tensioners and any
associated components checked and, if
necessary, replaced.
Testing Seat Belts
To confirm that seat belts are operating
correctly, perform these three simple checks
on each seat belt.
1. With the seat belt fastened, give the
webbing nearest the buckle a quick pull.
The buckle should remain securely locked.
