Front Passenger Occupant Detection
Model 3 has an occupancy sensor in the front passenger seat that controls the status of the front airbag.
NOTE: The occupancy classification system (OCS) meets the regulatory requirement of FMVSS 208 and
automatically detects when
inflating the passenger front airbag would be unnecessary or potentially harmful.
WARNING: Seating an infant in a rear facing child restraint system on a seat equipped with an operational
airbag can cause serious injury or death.

*If the passenger airbag status indicator does not match the situation, do not use the seat. The passenger must
ride in a
different seat. Contact Tesla Service.
NOTE: It takes approximately six seconds after you power on Model 3 for the occupant classification system (OCS)
to report accurate status of the front passenger airbag. As a result, when you
first power on Model 3, even in
situations when it should be OFF because the seat is occupied by a weight of
20 lbs (9 kg) or less, it will take the
touchscreen approximately six seconds to display the status, PASS AIRBAG OFF. If it fails to do so, contact Tesla
Service and do not seat a child in the front passenger seating position.
To make sure the sensing system can correctly detect occupancy status, eliminate the following:
WARNING: If seating a child in the front passenger seat is legally permissible in your market region, it is the
driver
Inflation EffectsWARNING: When airbags inflate, a fine powder is
released. This powder can irritate the skin and
should be thoroughly flushed from the eyes and
from any cuts or abrasions.
After inflation, the airbags deflate to provide a gradual
cushioning
effect for the occupants and to ensure the

High Beam Headlights
By default, Auto High Beam is enabled to allow high
beam headlights to automatically switch to low beam when there is light detected in front of
Model 3 (for
example, from an oncoming vehicle). To control this
feature, touch
Controls > Lights > Auto High Beam or
touch
Auto on the lights popup that displays on the
touchscreen when you pull the turn signal stalk toward
you.
NOTE: Auto High Beam is automatically enabled when
Autosteer is engaged. To switch to low beam headlights, push the turn signal stalk forward and release.
Auto High
Beam is re-enabled every time Autosteer is activated.
In situations where high beam headlights are off (for
example, lights are turned
off, or Auto High Beam is
active and light is detected in front of
Model 3) or you
are driving in daylight, you can temporarily turn on high
beams by pulling the turn signal stalk toward you. When
you release, high beam headlights turn
off (unless of
course, Auto High Beam is engaged and light is not detected in front of you). To
briefly flash the high beam
headlights, pull the turn signal stalk towards you and immediately release.
NOTE: Your chosen setting is retained until you manually
change it.
The following indicator lights are visible on the touchscreen to show the status of the headlights:
Low beam headlights are on.High beam headlights are on and Auto
High Beam is disabled or currently
unavailable.Auto High Beam is enabled and high
beams are on.
Model 3 is ready to turn off
the high beams if light is detected.
Auto High Beam is enabled but high beams
are not on because light is detected in front of
Model 3. When light is no longer
detected, high beams automatically turn
back on.
WARNING: Auto High Beam is an aid only and is
subject to limitations. It is the driver
The turn signals stop operating when canceled by the steering wheel, by moving the stalk in the opposite direction, or lightly pushing the stalk in the same
direction once more.
If Controls > Lights > Automatic Turn Signals is set to
Auto Cancel, turn signals cancel automatically when
Model 3 detects completion of a maneuver such as a
merge, lane change, or a fork in the roadway. If
Automatic Turn Signals is set to Off, you must cancel
the turn signal manually by using the turn stalk.
The corresponding turn signal indicator
lights up on the touchscreen when a turn
signal is operating.
Model 3 also emits a
clicking sound.

WARNING: When actively using Traffic-Aware
Cruise Control, engaging a turn signal can cause
Model 3 to accelerate in specific situations (see
Overtake Acceleration on page 83).
WARNING: When actively using Autosteer,
engaging a turn signal can cause Model 3 to
change lanes (see Auto Lane Change on page 87).
Hazard Warning Flashers
To turn on the hazard warning flashers, press the button
located above the rear view mirror. All turn signals
flash.
Press the button again to turn off the hazard warning
flashers.
NOTE: Hazard warning flashers operate even when
Model 3 cannot detect a key.
Condensation in Head or Tail Lights
Due to weather changes, humidity levels, or recent
exposure to water (such as a car wash), condensation may occasionally accumulate in your vehicle
Braking SystemsWARNING: Properly functioning braking systems
are critical to ensure safety. If you experience a
problem with the brake pedal, brake calipers, 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 briefly flashes amber on
the
touchscreen when you first start Model
3. If this indicator lights up at any other
time, an ABS fault has occurred and the ABS is not operating. Contact Tesla. The
braking system remains fully operational
and is not
affected by an ABS failure.
However, braking distances may increase. Drive cautiously and avoid heavy braking.
If the touchscreen displays this red brake
indicator at any time other than
briefly
when you first start Model 3, a brake
system fault is detected, or the level of the
brake
fluid is low. Contact Tesla
immediately. Apply steady pressure and
keep the brakes
firm to bring the vehicle to
a stop when safe to do so.
The touchscreen displays this amber brake
indicator if a brake booster fault is detected. Apply steady pressure and keep the brakes
firm to stop the vehicle when
safety permits. Hydraulic Boost
Compensation will be active (see
Hydraulic
Boost Compensation on page 61).
Emergency Braking
In an emergency, fully press the brake pedal and
maintain
firm pressure, even on low traction surfaces.
The ABS varies the braking pressure to each wheel according to the amount of traction available. This prevents wheels from locking and ensures that you stop as safely as possible.
WARNING: Do not pump the brake pedal. Doing so
interrupts operation of the ABS and can increase
braking distance.
WARNING: Always maintain a safe distance from
the vehicle in front of you and be aware of
hazardous driving conditions. While the ABS can
improve stopping distance, it cannot overcome the
laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of water
prevents direct contact between the tires and the
road).
CAUTION: Automatic Emergency Braking (see
Automatic Emergency Braking on page 112) may
intervene to automatically brake in situations
where a collision is considered imminent.
Automatic Emergency Braking is not designed to
prevent a collision. At best, it can minimize the
impact of a frontal collision by attempting to
reduce your driving speed. Depending on
Automatic Emergency Braking to avoid a collision
can result in serious injury or death.
CAUTION: In emergency situations, if the brakes
are not functioning properly, press and hold the
Park button on the drive stalk to bring the vehicle
to a stop. Do not use this method to stop the
vehicle unless absolutely necessary.
Dynamic Brake Lights (if equipped)
If you are driving over 30 mph (50 km/h) and brake
forcefully
(or if Automatic Emergency Braking engages),
the brake lights
flash quickly to warn other drivers that
Model 3 is rapidly slowing down. If Model 3 stops
completely, the hazard warning lights
flash. Flashing
continues until you press the accelerator or manually press the hazard lights button to turn them
off (see
Hazard Warning Flashers on page 55).
NOTE: Dynamic brake lights will not flash while Track
Mode is enabled (see
Track Mode on page 69).
NOTE: When towing a trailer (if applicable), the brake
lights on the trailer also operate as described above,
even when the trailer is not equipped with a separate
braking system.
WARNING: When towing a trailer (if applicable),
always increase your following distance. Sudden
braking may result in skidding, jack-knifing, and
loss of control.
Brake Disc Wiping
To ensure brakes remain responsive in cold and wet
weather,
Model 3 is equipped with brake disc wiping.
When cold and wet weather is detected, this feature repeatedly applies an imperceptible amount of brake
force to remove water from the surface of the brake discs.

Hydraulic Fade Compensation
Model 3 is equipped with hydraulic fade compensation.
This assists in monitoring brake system pressure and ABS activity for instances of reduced brake
performance. If reduced brake performance is detected (for example, as a result of brake fade, or cold or wet
conditions), you may hear a sound, feel the brake pedal pull away from your foot, and notice a strong increase in braking. Brake as you normally would and continue to
press the brake pedal without releasing or pumping the
brakes.
CAUTION: If brakes are not functioning properly,
stop the vehicle when safety permits and contact
Tesla Service. See Park on page 51 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 exercise
caution when driving conditions are hazardous.
Brake disc wiping and hydraulic fade
compensation is not a substitute for adequately
applying the brakes.
Hydraulic Boost Compensation
Model 3 is equipped with a brake booster that activates
the brakes when the brake pedal is pressed. Hydraulic boost compensation provides mechanical assistance if the brake booster fails. If a brake booster failure is detected, the brake pedal feels
stiffer to press and you
may hear a sound when you press the brake pedal. To
stop
Model 3, apply steady force to the brake pedal
without releasing or pumping. Drive cautiously and
maintain a safe distance from other road users
