Seat BeltsWearing Seat Belts
Using seat belts and child safety seats is the
most effective way to protect occupants if a
collision occurs. Therefore, wearing a seat belt
is required by law in most jurisdictions.
Both the driver and passenger seats are equipped with three-point inertia reel seatbelts. Inertia reel belts are automatically
tensioned to allow occupants to move
comfortably during normal driving conditions.
To securely hold child safety seats, all
passenger seating positions are equipped with an automatic locking retractor (ALR) that, by
pulling the seat belt beyond the length
needed for a typical adult occupant, locks the belt into place until the seat belt is unbuckled
(see Installing Seat Belt Retained Child Seats
on page 11).
The seat belt reel automatically locks to prevent movement of occupants if Model S
experiences a force associated with hard
acceleration, braking, cornering, or an impact in a collision.The seat belt reminder on the
instrument panel alerts you if a seat
belt for an occupied seat is not
fastened. If the belt remains
unfastened, the reminder flashes and
an intermittent chime sounds. If all
occupants are buckled up and the
reminder stays on, re-fasten seat
belts to ensure they are correctly
latched. Also remove any heavy
objects (such as a briefcase) from an
unoccupied seat. If the reminder
light continues to stay on, contact
Tesla.To Fasten a Belt
1. Ensure correct positioning of the seat.
2.
Draw the belt out smoothly, ensuring the
belt lays flat across the pelvis, chest and
mid-point of your collar bone, between
the neck and shoulder.
3. Insert the latch plate into the buckle and
press together until you hear a click indicating it is locked in place.
4. Pull the belt to check that it is securely
fastened.
5. Pull the diagonal part of the belt toward
the reel to remove excess slack.
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 an accident.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.
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 accident,
have the airbags, seat belt pre-tensioners and any associated components checkedand, 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.
2. With the belt unfastened, unreel the
webbing to its limit. Check that unreeling
is free from snags, and visually check the
webbing for wear. Allow the webbing to
retract, checking that retraction is smooth
and complete.
3. With the webbing half unreeled, hold the
tongue plate and pull forward quickly. The
mechanism should lock automatically and
prevent further unreeling.
If a seat belt fails any of these tests, contact Tesla immediately.
Seat Belt WarningsWarning: Seat belts should be worn by all
occupants at all times, even if driving for a very short distance. Failure to do so
increases the risk of injury or death if an
accident occurs.Warning: Secure small children in a
suitable child safety seat. Always follow
the child safety seat manufacturer's
instructions when installing.Warning: Ensure that all seat belts are
worn correctly. An improperly worn seat
belt increases the risk of injury or death if
an accident occurs.Warning: Do not wear seat belts over
hard, fragile or sharp items in clothing, such as pens, keys, eyeglasses, etc. The
pressure from the seat belt on such items can cause injury.Warning: Seat belts should not be worn
with any part of the strap twisted.Warning: Each seat belt assembly must
be used by one occupant only. It is
dangerous to put a seat belt around a
child being carried on an occupant’s lap.Warning: Seat belts that have been worn
in an accident must be inspected or
replaced by Tesla, even if damage to the
assembly is not obvious.Warning: Seat belts that show signs of
wear (such as fraying), or have been cut or damaged in any way, must be replacedby Tesla.Warning: Avoid contaminating a seat
belt’s components with any chemicals,
liquids, grit, dirt or cleaning products. If a
seat belt fails to retract or latch into the
buckle, it must be replaced immediately.
Contact Tesla.Warning: Do not make modifications or
additions that can prevent a seat belt
mechanism from taking up slack, or that
can prevent a seat belt from being
adjusted to remove slack. A slack belt
greatly reduces occupant protection.Warning: Do not make modifications that
can interfere with the operation of a seat
belt, or that can cause a seat belt to
become inoperable.Warning: When seat belts are not in use,
they should be fully retracted and not hanging loose. If a seat belt does not fullyretract, contact Tesla.

Child Safety SeatsGuidelines for Seating ChildrenYou must restrain infants and small children using a child safety seat appropriate for the child’sage, weight, and size. Never seat a child in a child safety seat or a booster seat on the front
passenger seat when the airbag is activated. To disable the front passenger seat airbag, see
Disabling the Passenger Front Airbags on page 20. Carefully follow the instructions provided by
the manufacturer of the child safety seat.Warning: Never use a rearward facing child restraint on a seat protected by an ACTIVE
AIRBAG in front of it. DEATH or SERIOUS INJURY to the child can occur. Refer to the
following label fitted to both sides of the passenger sunvisor.
If your Model S is equipped with the optional Tesla built-in rear facing child seats, these seats are
child safety seats and are designed only for children within a specific height and weight range
(see Tesla Built-In Rear Facing Child Seats on page 14).

Seating Larger Children
If a child is too large to fit into a child safety
seat, but too small to safely fit into the standard seat belts, use a booster seat
appropriate for the child’s age and size. Carefully follow the manufacturer’s
instructions to secure the booster seat using
the seat belts. Do not use the ISOFIX system to secure booster seats, even in situationswhere the booster seat is equipped with the
ISOFIX system.
Installing Child Safety Seats
There are two general methods used to install child safety seats:
• Seat belt retained - these seats are secured using the vehicle’s seat belts (see
Installing Seat Belt Retained Child Seats
on page 11).
• ISOFIX retained - these seats can attach to anchor bars built into the vehicle’s rear
seats (see Installing ISOFIX Child Seats on
page 12).
Check the child safety seat manufacturer’s
instructions and the table on Child Safety
Seats on page 8 to determine which
installation method to use. Some child safety
seats can be installed using either method.
Always follow the child safety seat
manufacturer’s instructions.
Installing Seat Belt Retained Child Seats
First, make sure that the child falls into the
correct weight range for the seat.
Avoid dressing the child in bulky clothing and do not place any objects between the child
and the restraint system.
Adjust harnesses for every child, every trip.To securely hold child safety seats, all
passenger seating positions are equipped with
an automatic locking retractor (ALR) that, by pulling the seat belt beyond the length
needed for a typical adult occupant, locks the
belt into place until the seat belt is unbuckled
and the webbing is fully retracted. The ALR
mechanism operates as a ratchet, winding in
slack and preventing the seat belt from
extending any further until it has been
completely rewound. When installing a child
safety seat, engage the belt's automatic
locking retractor by pulling the seat belt
webbing until it is fully extended. The ALR
system engages only when the seat belt is at its maximum extension point.
Note: An automatic locking retractor
disengages only when the seat belt is
unbuckled and fully retracted. The belt can then be worn as a normal belt, sliding freely inand out and locking tight only in an
emergency. Once disengaged, the belt must be fully extended to re-engage the locking
mechanism whenever you install a child safety seat.
Always follow the detailed instructions provided by the child safety seat
manufacturer. General guidelines are provided
below.
1. Place the child safety seat in Model S, and
fully extend the seat belt. Route and
buckle the seat belt in accordance with the child safety seat manufacturer’s
instructions.
2. Allow the seat belt to retract, and remove
all slack in the seat belt while firmly
pushing the child safety seat into the Model S seat.

3.If the seat belt retained child safety seat
has an upper tether, attach it to the back of the seat (see Attaching Upper Tether
Straps on page 12).
Installing ISOFIX Child Seats
Lower ISOFIX anchor positions are provided
in the second-row outboard seating positions
and are located between the seat's back rest
and rear cushion. The exact location of each
anchor is identified by a child safety seat
identification button, illustrated below. The button is located on the seat back, directlyabove its associated anchor.
Install ISOFIX seats in the outboard seating
positions only. Use only a seat belt retained
seat in the center position.
To install a ISOFIX retained child safety seat,
slide the safety seat latches onto the anchor
bars until they click into place. Carefully read
and follow the instructions provided by the child safety seat manufacturer.
Once installed, test the security of the
installation before seating a child. Attempt to
twist the child safety seat from side to side and try to pull it away from the seat, then
check that the anchors are still securely in place.
Attaching Upper Tether Straps If an upper tether strap is provided, attach its
hook to the anchor point located on the back
of the rear seats. Always position single-strap
tethers so that it runs over the center of the
Model S head support. Tighten dual-strap
tethers to run on each side of the head
support. Tighten according to the child safety
seat manufacturer’s instructions.
Note: To prevent single-strap tethers from
moving from side to side, the top of the head
support deforms.
