WARNING: To minimize the risk of severe injury or
death in the event of a collision, ensure that head
supports are positioned correctly before sitting in,
or operating, Model 3.
WARNING: When installing a seat belt retained
child safety seat in the center seating position in
the second row, you must lower the associated
head support (described next).

Front and Rear Seats
25Seating and Safety Restraints

Wearing 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 seat belts. 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) feature that, by fully extracting the seat
belt (beyond the length needed for a typical adult
occupant), locks the belt into place until the seat belt is
unbuckled.
The seat belt reel automatically locks to prevent
movement of occupants if
Model 3 experiences a force
associated with hard acceleration, braking, cornering, or
an impact in a collision.
Seat Belt Reminders
The seat belt reminder on the touchscreen
alerts you if a seat belt for an occupied driver or passenger seat is unbuckled. If
the belt remains unbuckled, the reminder
flashes and an intermittent chime sounds.
If all occupants are buckled up and the
reminder stays on, re-buckle 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.
You can temporarily mute a seat belt reminder
associated with a rear seating position. This is useful in situations when you are carrying an object in a rear seat
that triggers the seat belt reminder alert. To mute the reminder, touch the associated seat on the seat belt reminder card that displays on the touchscreen when a seat belt reminder alert is active. When a reminder is muted, the seat belt reminder icon is replaced by a seat icon. Touch the seat again to unmute the reminder. The reminder is disabled for the current drive only.
WARNING: Seat belts must be worn by passengers
in all seating positions. Do not disable a seat belt
reminder when the seating position is occupied by
a passenger.
To Fasten a Belt
1.
Ensure correct positioning of the seat (see Correct
Driving Position on page 23).
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 Adjust the Shoulder Anchor
Height
Model 3 is equipped with an adjustable shoulder anchor
for each front seat to ensure that the seat belt is positioned correctly. The seat belt should lay
flat across
the mid-point of your collar bone while in the correct driving position
(see Correct Driving Position on page
23. Adjust the height of the shoulder anchor if the seat
belt is not positioned correctly:
1.
Press and hold the button on the shoulder anchor to release the locking mechanism.
2.
While holding the button, move the shoulder anchor up or down as necessary so that the seat belt is
positioned correctly.
3.
Release the button on the shoulder anchor so that it
locks into position.
Seat Belts
27Seating and Safety Restraints

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.
For information about cleaning seat belts, see Seat Belts
on page 168.
Seat Belt Warnings
WARNING: 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 a collision occurs.
WARNING: Secure small children in a suitable child
safety seat as described in the Child Safety Seat
topic. Always follow the child safety seat
manufacturer

In the second row, install LATCH child safety seats in the
outboard seating positions only. Use only a seat belt
retained seat in the center position.
To install a LATCH 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 to ensure the anchors remain securely in
place.
NOTE: Lower LATCH anchors should not be used with
child seats or booster seats that have an integrated safety belt in situations where the combined weight of
the child plus the child restraint is more than
65 lbs (29.5
kg). In these situations, use the safety belt instead.
Attaching Upper Tether Straps
If an upper tether strap is provided, attach its hook to the anchor point located on the shelf behind the rear
seats.
NOTE: The location of anchor points may not be readily
visible but can be found by identifying a slice in the seat

To access an anchor point, press down on the back of its
cover.
For dual-strap tethers, position a strap on each side of
the head support.
For single-strap tethers at the outboard seating positions, run the strap over the outside-facing side of the head support (same side of the head support as the
seat belt retraction mechanism).
For a single-strap tether in the center seating position,
fully lower the head support
(see Head Supports on
page 24) and run the strap over the top center of the
head support.
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 one inch (2.5 cm), it is
too loose. Tighten the belt or reconnect the
LATCH
retained child safety seat.
3.
If you are unable to reduce slack, try a different seat
location or try another child safety seat.
Child Safety Seat Warnings
WARNING: Extreme hazard! Do not seat a child on
the front passenger seat even if you are using a
child safety seat. This seat has an airbag in front of
it. Although this airbag is disabled when Model 3
detects a lightweight passenger, do not rely on
technology to protect your child.
WARNING: Child restraint systems are designed to
be secured in vehicle seats by lap belts or the lap
belt portion of a lap-shoulder belt. Children could
be endangered in a crash if their child restraints
are not properly secured in the vehicle.
WARNING: According to collision statistics,
children are safer when properly restrained in the
rear seating positions than in the front seating
positions.
WARNING: Do not use a forward facing child
safety seat until your child weighs over 20 lbs (9
kg) and can sit independently. Up to the age of
two, a child
