warning TESLA MODEL 3 2020 s User Guide

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.
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 173.
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 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

Child Safety Seats
Guidelines for Seating Children
Your Model 3 seat belts are designed for adults and larger children. You must restrain infants and small children in the second row seats only, and you must use a suitable child safety seat
appropriate for the child’s age, weight, and size.
Warning: Never seat a child on a seat with an ACTIVE AIRBAG in front of it. DEATH or
SERIOUS INJURY to the child can occur. See Passenger Front Airbag Status on page 43.Warning: Do not associate the Easy Entry setting with the driver

Choosing a Child Safety SeatAll children age 12 and under should ride in the second and third row seats. Always use a child
safety seat suitable for a young child’s age and weight. The following table is based on child
safety seat recommendations determined by the National Highway Traffic Safety Administration
(NHTSA) in the United States (for more information, go to www.nhtsa.gov/ChildSafety/Guidance).InfantsToddlersYoung

CHECK THE CHILD SAFETY SEAT MANUFACTURER’S INSTRUCTIONS AND CAREFULLY
FOLLOW ALL INSTRUCTIONS
** ISOFIX is the international standard for attachment points for child safety seats in passenger
cars. The system has other regional names including LATCH ("Lower Anchors and Tethers for
Children") in the United States and LUAS ("Lower Universal Anchorage System") or Canfix in
Canada. It has also been called the "Universal Child Safety Seat System" or UCSSS.
*** Subject to instructions provided by the child safety seat manufacturer.Warning: Laws that govern how and where children should be carried when traveling in a
vehicle are subject to change. It is the driver’s responsibility to keep up to date on, and
comply with, all current regulations in the region(s) where Model 3 is driven. To check the
child passenger safety laws for states in the U.S., go to: http://www.ghsa.org/html/stateinfo/
laws/childsafety_laws.html.Warning: Do not use LATCH/Isofix/i-Size anchors with child restraint system or booster seats
that have an integral safety belt where the combined weight of the child plus the child restraint system exceeds 65 lbs (29.5 kg).

For dual-strap tethers, position a strap oneach 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 (sameside 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 Raising/Lowering the Rear Center HeadSupport on page 29) 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

Braking and Stopping
Braking Systems
Warning: Properly functioning braking
systems are critical to ensure safety. If you experience a problem with the brake
pedal, brake caliper, or any component of
a Model 3 braking system, contact Tesla
immediately.
Model 3 has an anti-lock braking system (ABS)
that prevents the wheels from locking when
you apply maximum brake pressure. This improves steering control during heavy
braking in most road conditions.
During emergency braking conditions, the
ABS constantly monitors the speed of each
wheel and varies the brake pressure according to the grip available.
The alteration of brake pressure can be felt as
a pulsing sensation through the brake pedal.
This demonstrates that the ABS is operating
and is not a cause for concern. Keep firm and
steady pressure on the brake pedal while
experiencing the pulsing.
The ABS indicator brie

Caution: If the brakes are not functioning
properly, stop the vehicle as soon as safety permits and contact Tesla Service.
See Park on page 56 for information on
using the Park button to stop the vehicle
in case of emergency.Warning: Always maintain a safe driving
distance from the vehicle in front of you
and be cautious in hazardous driving
conditions. Do not rely on brake disc
wiping or hydraulic fade compensation to act as a substitute for adequate braking.
Regenerative Braking
Whenever Model 3 is moving and your foot is
off the accelerator, regenerative braking slows
down Model 3 and feeds any surplus energy back to the Battery.
By anticipating your stops and reducing or
removing pressure from the accelerator pedal
to slow down, you can take advantage of regenerative braking to increase driving range.
Of course, this is no substitute for regular braking when needed for safety.
Note: If regenerative braking is aggressively
slowing Model 3 (such as when your foot is
completely off the accelerator pedal at
highway speeds), the brake lights turn on to
alert others that you are slowing down.
Note: Installing winter tires with aggressive
compound and tread design may result in
temporarily-reduced regenerative braking
power. However, your vehicle is designed to continuously recalibrate itself, and after changing tires it will increasingly restore
regenerative braking power after some
moderate-torque straight-line accelerations.
For most drivers this occurs after a short
period of normal driving, but drivers who
normally accelerate lightly may need to use
slightly harder accelerations while the
recalibration is in progress.
Warning: In snowy or icy conditions
Model 3 may experience traction loss
during regenerative braking, particularly
when in the Standard setting and/or not
using winter tires. Tesla recommends
using the Low setting (see To Set the
Regenerative Braking Level on page 66)
in snowy or icy conditions to help maintain vehicle stability.The amount of energy fed back to the Battery
using regenerative braking can depend on the
current state of the Battery and the charge
level setting that you are using. For example,
regenerative braking may be limited if the Battery is already fully charged or if the
ambient temperature is too cold.
Note: If regenerative braking is limited, a
dashed line displays on the energy bar (see
Driving Status on page 63).
To Set the Regenerative Braking Level
You can use the touchscreen to change the
level of regenerative braking:
1. Touch Controls > Driving > Regenerative
Braking .
2. Choose from two levels:

Note: The parking brake operates on the rear
wheels only, and is independent of the pedal-
operated brake system.
Warning: In snowy or icy conditions the
rear wheels may not have sufficient
traction to prevent Model 3 from sliding
down a slope, particularly if not using winter tires. Avoid parking on hills in
snowy or icy conditions. You are always responsible for parking safely.Warning: Your Model 3 may display an
alert if the road is too steep to safely park
on, or if the parking brakes are not
properly engaged. These alerts are for
guidance purposes only and are not a
substitute for the driver’s judgment of safe parking conditions, including specific
road or weather conditions. Do not
depend on these alerts to determine
whether or not it is safe to park at any location. You are always responsible for
parking safely.When you use the touchscreen to
manually apply the parking brake,
the red parking brake indicator lights
up on the touchscreen.If the parking brake experiences an
electrical issue, the amber parking brake indicator lights up and a fault
message displays at the top of the
touchscreen.Caution: In the unlikely event that Model 3
loses electrical power, you cannot access
the touchscreen and are therefore unable to release the parking brake without first
jump starting Model 3 (see Instructions
for Transporters on page 199).Brake Wear
Model 3 brake pads are equipped with wear indicators. A wear indicator is a thin metal
strip attached to the brake pad that squeals as
it rubs against the rotor when the pad wears
down. This squealing sound indicates that the
brake pads have reached the end of their service life and require replacement. To
replace the brake pads, contact Tesla Service.
Brakes must be periodically inspected visually by removing the tire and wheel. For detailed
specifications and service limits for rotors and
brake pads, see Subsystems on page 188.
Additionally, Tesla recommends cleaning and
lubricating the brake calipers every year or
12,500 miles (20,000 km) if in an area where
roads are salted during winter months.Warning: Neglecting to replace worn
brake pads damages the braking system
and can result in a braking hazard.

Park Assist
How Park Assist Works
Model 3 has several sensors designed to
detect the presence of objects. When driving
slowly in Drive or Reverse (for example, when
parking), the sensors alert you if an object is
detected in close proximity of your Model 3.
Objects are only detected in the direction of
the gear you selected; front objects in Drive,
rear objects in Reverse.
Warning: You may not be alerted if Model
3 rolls freely in the opposite direction of
the gear you selected (for example, you
will not receive an alert if Model 3 rolls
backwards down a hill while in Drive).
The sensors are activated when driving slower
than 5 mph (8 km/h).
Warning: Never depend on Park Assist to
inform you if an area you are approaching is free of objects and/or people. Several
external factors can reduce theperformance of Park Assist, causing
either no readings or false readings (see
Limitations and False Warnings on page
71). Therefore, depending on Park Assist
to determine if Model 3 is approaching an
obstruction can result in damage to the vehicle and/or objects, and can
potentially cause serious injury. Always
inspect the area with your own eyes.
When reversing, perform shoulder checks and use all mirrors. Park assist does not
detect children, pedestrians, bicyclists,
animals, or objects that are moving, protruding, located too far above or
below the sensors, or too close or too far
from the sensors. Park Assist is for
guidance purposes only and is not intended to replace your own direct visual
checks. It is not a substitute for careful
driving.
Visual and Audio Feedback
When you shift to Reverse, the Park Assist
view displays on the touchscreen, showing objects that are in close proximity to the front
and rear of Model 3. This view closes when you shift into Drive unless an object is
detected close to the front of Model 3, in
which case the Park Assist view closes automatically when your driving speed
exceeds 5 mph (8 km/h). When reversing,
visual feedback also displays on the touchscreen, immediately below the camera
view (see Rear View Camera on page 75).
You can manually close the park assist view on
the touchscreen by touching the X in the
upper corner.
When driving with the Camera app displayed
on the touchscreen, you can switch to the
Park Assist view when driving at speeds below
5 mph (8 km/h). Touch the button located in
the upper left corner of the Camera app
window. This is useful if you need assistance
with parallel parking.
If chimes are turned on (see Controlling
Audible Feedback on page 71), an audible
beep sounds as you approach an object. You
can temporarily mute the chime by pressing
the scroll button on the left side of the
steering wheel or by touching the mute button on the bottom left corner of the Park Assist
view.
Note: If a sensor is unable to provide
feedback, the touchscreen displays an alert
message.

Caution: Keep sensors clean from dirt,
debris, snow, and ice. Avoid using a high
pressure power washer on the sensors
and do not clean a sensor with a sharp or abrasive object that can scratch or
damage its surface.Caution: Do not install accessories or
stickers on or near the parking sensors.
Controlling Audible Feedback
You can use Park Assist with or without
audible feedback. To turn chimes on or off,
touch Controls > Safety & Security > Park
Assist Chimes .
To mute the chimes temporarily, press the
scroll button on the left side of the steering
wheel or touch the mute button in the corner
of the Park Assist view. The chimes are muted
until you shift into a different gear or drive
over 5 mph (8 km/h).
