Controlling the Passenger Front Airbag
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 safety seat 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:

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 yellow 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 yellow 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 59).
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).
NOTE: Automatic Emergency Braking (see Automatic
Emergency Braking on page 113) 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.
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 also equipped with hydraulic fade
compensation. This feature 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".
CAUTION: If brakes are not functioning properly,
stop the vehicle when safety permits and contact
Tesla Service. See Park on page 50 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.
Braking and Stopping
58MODEL 3 Owner

How It Works
The traction control system constantly monitors the speed of the front and rear wheels. If
Model 3
experiences a loss of traction, the system minimizes wheel spin by controlling brake pressure and motor power. By default, the traction control system is on. Under normal conditions, it should remain on to ensure
maximum safety.
This yellow indicator flashes on the
touchscreen whenever the traction control
system is actively controlling brake
pressure and motor power to minimize wheel spin. If the indicator stays on, a fault is detected with the traction control system. Contact Tesla Service.
WARNING: Traction control cannot prevent
collisions caused by driving dangerously or turning
too sharply at high speeds.
Allowing Wheel Slip
To allow the wheels to spin at a limited speed, you can
enable Slip Start.
Slip Start can be enabled at any speed,
however it is less effective at higher speeds.
Under normal conditions, Slip Start should not be enabled. Enable it only in circumstances where you deliberately want the wheels to spin, such as:

This is often a temporary issue that will clear up when condensation evaporates or a particular environmental
condition is no longer present.
If the alert does not clear by the end of your drive, inspect and clean the front camera area at the top center of the
windshield before your next planned drive. Check the camera surface for condensation, dirt, or other debris and
attempt to clear any obstruction. See the
About Autopilot on page 78 sections “How It Works” and “Cleaning
Cameras and Sensors” for more on front camera location and tips for careful cleaning.
Although condensation on the inside of the front camera enclosure cannot be wiped clean, you can usually clear it
quicker by following these steps:
1.
Pre-condition the cabin with the temperature set to High and A/C turned ON.
2.
Turn on the front windshield defroster.
Once all front cameras regain adequate visibility, the alert will clear and both Traffic-Aware Cruise Control and
Autosteer should again be available.
If this alert persists throughout subsequent drives but no front camera obstruction is visible, schedule service at your earliest convenience. Your vehicle is OK to drive in the meantime.

Cruise control unavailable
Continue driving to allow cameras to calibrate
Traffic-Aware Cruise Control and Autosteer are unavailable because the cameras on your vehicle are not fully
calibrated. Continue to your destination. Your vehicle is OK to drive.
Traffic-Aware Cruise Control and Autosteer will remain unavailable until camera calibration is complete.
Your vehicle must maneuver with great precision when features like Traffic-Aware Cruise Control and Autosteer are
active. Before these features can be used for the
first time, the cameras must complete an initial self-calibration.
Occasionally, one or more cameras can become uncalibrated.
For your convenience, a calibration progress indicator is displayed on the touchscreen. Calibration typically completes after your vehicle has driven 20-25 miles (32-40 km), but the distance varies depending on road and
environmental conditions. For example, driving on a straight road with highly visible lane markings helps the cameras calibrate quicker.
See Drive to Calibrate Cameras on page 79 for more information.
When calibration is complete, Traffic-Aware Cruise Control and Autosteer should be available.
If the alert persists and camera calibration has not completed after your vehicle has driven 100 miles (160 km) or
more, or
Traffic-Aware Cruise Control and Autosteer remain unavailable despite successful camera calibration,
schedule service at your earliest convenience. Your vehicle is OK to drive in the meantime.

Camera blocked or blinded
Clean camera or wait for it to regain visibility
One or more of the vehicle cameras is blocked or blinded due to external conditions. When the cameras cannot
provide accurate visual information, some or all Autopilot features may be temporarily unavailable.
Cameras can be blocked or blinded due to many factors, including:
