Seat Belt Pre-tensionersThe 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 (see Choosing a Child Safety Seat on page 9). 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 Airbag on page 21. 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 15).
Choosing a Child Safety Seat
Refer to the tables below for guidelines on the type of seat belt installed and ISOFIX installed
child restraint you should use based on the weight of the child.

Note: If the combined weight of the child and the child safety seat is over 29 kg, Tesla
recommends attaching the safety seat using the seat belt and upper tether strap. In addition to
safety, this has the added benefit of ensuring the seat belt reminder does not stay lit. Always
follow the seat belt manufacturer’s instructions when installing child safety seats.

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 Choosing a Child Safety Seat on page 9 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.
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,
route the seat belt, and secure the buckle
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 13).

Installing ISOFIX Child Seats
Lower ISOFIX anchor positions are provided
in the second-row seats and are located
between the seat's back rest and rear cushion. The exact location of each anchor is identifiedby a child safety seat identification button,illustrated below. The button is located on the
seat back, directly above its associated
anchor. Some Model S vehicles have two
ISOFIX seating positions (outboard seating
positions only) whereas others have three.
On vehicles with the center ISOFIX position,
you can install two ISOFIX seats adjacent to
each other only if you install one of the seats on the right (passenger side) and the other in
the center, as illustrated below. To seat three children, use a seat belt retained seat in the
center position.
On vehicles without the center ISOFIX
position, install ISOFIX seats in the outboard
seating positions only and always use a seat
belt retained seat in the center position.
Safety Information

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 the strap so
that it runs over the center of the Model S
head support, except in cases where you are
installing a ISOFIX retained child safety seat in
the center position—in this case, run the strap
over the left hand side of the head support, as
shown. Tighten according to the child safety
seat manufacturer’s instructions.
Note: To prevent the strap from moving from
side to side, the top of the head support
deforms.
Testing a Child Safety Seat
Before seating a child, always make sure the child safety seat is not loose:
1. Hold the child safety seat by the belt path
and try to slide the safety seat from side
to side and front to back.
2. If the seat moves more than 2.5 cm, it is
too loose. Tighten the belt or reconnect the ISOFIX retained child safety seat.
3. If you are unable to reduce slack, try a
different seat location or try another child
safety seat.
