2023 TESLA MODEL 3 warning light

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.
The corresponding turn signal indicator

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.
Braking and Stopping
60MODEL 3 Owner

NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Autosteer, or the
feature may not operate exactly as described.
NOTE: Autosteer is a BETA feature.
Autosteer builds upon Traffic-Aware Cruise Control (see
Traffic-Aware Cruise Control on page 80), intelligently
keeping
Model 3 in its driving lane when cruising at a set
speed.
Autosteer also allows you to use the turn signals
to move Model 3 into an adjacent lane (see Auto Lane
Change on page 87). Autosteer detects lane markings
and the presence of vehicles and objects to
steer Model
3.
NOTE: To display more details about the roadway and its
surroundings, such as road markings, stop lights, objects (such as trash cans and poles), etc., touch
Controls >
Autopilot > Full Self-Driving Visualization Preview (if
equipped).
CAUTION: Ensure all cameras and sensors (if
equipped) are clean. Dirty cameras and sensors, as
well as environmental conditions such as rain and
faded lane markings, affect performance.
WARNING: Autosteer is a hands-on feature. You
must keep your hands on the steering wheel at all
times.
WARNING: Autosteer is intended for use on
controlled-access highways with a fully attentive
driver. When using Autosteer, hold the steering
wheel and be mindful of road conditions and
surrounding traffic. Do not use Autosteer in
construction zones, or in areas where bicyclists or
pedestrians may be present. Never depend on
Autosteer to determine an appropriate driving
path. Always be prepared to take immediate
action. Failure to follow these instructions could
cause damage, serious injury or death.
Operating Autosteer
Before you can operate Autosteer, you must enable it by touching
Controls > Autopilot > Autosteer (Beta).
To indicate that Autosteer is available (but
not actively steering
Model 3), the top
corner of the touchscreen displays a gray
Autosteer icon
next to the driving gear.
To initiate Autosteer, move the drive stalk fully down
twice in quick succession.
To indicate that Autosteer is now actively
steering
Model 3, the touchscreen displays
the Autosteer icon in blue. When Autosteer is able to detect lane markings, it also
displays the driving lane in blue.
Autosteer briefly displays a message on the touchscreen
reminding you to pay attention to the road and be ready
to take over at any time.
The speed at which you can initiate Autosteer can vary depending on various conditions and whether or not a vehicle is detected ahead of you. When no vehicle is
detected ahead of you, you must be driving at least
18 mph (30 km/h), unless certain vehicle and
environmental conditions are met, in which case, you
may be able to initiate it at lower speeds. When a
vehicle is detected ahead of you, you can initiate
Autosteer at any speed, even when stationary, provided
Model 3 is at least 5 feet (150 cm) behind the detected
vehicle.
NOTE: Auto High Beam is automatically enabled when
Autosteer is engaged and the maximum cruising speed is
85 mph (140 km/h).
CAUTION: If available in your market region, Model
3 detects lights from an emergency vehicle when
using Autosteer at night on a high speed road, the
driving speed is automatically reduced and the
touchscreen displays a message informing you of
the slowdown. You will also hear a chime and see a
reminder to keep your hands on the steering
wheel. When the light detections pass by or cease
to appear, Autopilot resumes your cruising speed.
Alternatively, you may tap the accelerator to
resume your cruising speed.
WARNING: Never depend on Autopilot features to
determine the presence of emergency vehicles.
Model 3 may not detect lights from emergency
vehicles. Keep your eyes on your driving path and
always be prepared to take immediate action.
In situations where Autosteer is temporarily unavailable, the Autosteer icon disappears. For example, your driving speed is not within the speed required for Autosteer to operate. Autosteer may also be unavailable if it is not receiving adequate data from the camera(s).
NOTE: In low light conditions (dusk or dark), Autosteer
aborts or is unavailable if headlights are set to
Off. For
best results, set headlights to
Auto.
If unable to detect lane markings, Autosteer may determine the driving lane based on a vehicle you are
following.
In most cases, Autosteer attempts to center Model 3 in
the driving lane. However, there may be situations in which Autosteer may steer
Model 3 in a driving path that
is
offset from the center of the lane (for example,
detection of guard rails).
Autosteer
85Autopilot

In situations where Auto Lane Change is unable to operate at optimal performance, or cannot operate due to inadequate data, the
touchscreen displays a series of
warnings. Therefore, when using Auto Lane Change,
always pay attention to the
touchscreen and be
prepared to manually steer
Model 3.
Adjacent Lane Speed
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Adjacent Lane
Speed, or the feature may not operate exactly as
described.
When moving significantly faster than vehicles in
adjacent lanes,
Model 3 automatically reduces the
driving speed. This is especially helpful in heavy
traffic
situations or when vehicles are constantly merging into
different lanes. When Model 3 detects other vehicles
driving
significantly slower, the touchscreen highlights
the adjacent lanes with arrows and detected vehicles in gray, and
Model 3 reduces the driving speed as
appropriate. To temporarily override this feature, press
the accelerator pedal.
WARNING: Never depend on Autopilot to
determine a safe driving speed; you are
responsible for driving safely and according to
traffic laws in your market region.
Stop Light and Stop Sign Warning
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Stop Light and
Stop Sign Warning, or the feature may not operate
exactly as described.
While Autosteer is in use, Model 3 displays a warning on
the
touchscreen and sounds a chime if it detects that
you are likely to run through a red stop light or stop sign. If this happens,
TAKE IMMEDIATE CORRECTIVE
ACTION!
The visual and audible warnings cancel after a few seconds, or when you press the brake pedal, whichever
comes
first.
Stop Light and Stop Sign Warning provides warnings
only. It does not slow down or stop
Model 3 at red traffic
lights, stop signs, road markings, etc. If equipped with
Traffic Light and Stop Sign Control, you can enable this
feature to automatically stop Model 3 at traffic lights
and stop signs (see Traffic Light and Stop Sign Control
on page 93).
CAUTION: Stop Light and Stop Sign Warning
requires on-board maps to know that a particular
stop light or stop sign exists at a location. In some
cases, map data is inaccurate or outdated and may
not include all stop lights or stop signs. Therefore,
Stop Light and Stop Sign Warning may not detect
all stop lights and stop signs.
WARNING: The Stop Light and Stop Sign Warning
feature does not apply the brakes or decelerate
Model 3 and may not detect all stop lights and
stop signs. Stop Light and Stop Sign Warning is
designed for guidance purposes only and is not a
substitute for attentive driving and sound
judgment. Keep your eyes on the road when
driving and never depend on Stop Light and Stop
Sign Warning to warn you of a stop light or stop
sign.
WARNING: Stop Light and Stop Sign Warning is
designed to warn you only when approaching a
visible red stop sign, solid red or later portion of a
yellow traffic light. It may not warn you of
intersections with flashing lights and it does not
warn you of yield signs or temporary stop and
yield signs (such as those used in construction
areas). Additionally, Stop Light and Stop Sign
Warning does not warn you of approaching stop
lights or stop signs when you are pressing the
accelerator pedal or brake pedal (which disables
Autosteer).
Limitations
Autosteer and its associated functions are particularly
unlikely to operate as intended when:

Stop Signs and Road Markings
When driving with Autosteer or Traffic-aware Cruise Control engaged, and Traffic Light and Stop Sign Control
enabled,
Model 3 is designed to respond as follows when approaching intersections controlled by stop signs, stop
lines, or road markings:
Type of IntersectionVehicle Intended Response
No Traffic Control
Arm of T-junction
Model 3 assumes the right of way and continues straight without slowing down or
stopping.
End of T-junction
If Model 3 detects a T-junction based on the map data, Model 3 slows down and
comes to a complete stop at the red stop line displayed on the
touchscreen. When
you want to proceed, you must take over steering and acceleration.
WARNING: Model 3 may not stop at a T-junction that does not have a stop sign
or stop line, or if the T-junction is not included in the map data. Drive
attentively and be prepared to stop (when necessary and/or appropriate).
Stop Sign
Model 3 slows down and comes to a complete stop at the red stop line displayed on
the
touchscreen. When you want to proceed through the intersection, you must
press down on the drive stalk or briefly press the accelerator pedal.
NOTE: If you confirm that you want to proceed through an intersection controlled by
a stop sign by
pressing down on the drive stalk or briefly pressing the accelerator
pedal before
Model 3 has stopped, your confirmation is ignored. Model 3 is not
designed to proceed through a stop sign without stopping.
NOTE: Even when using Autosteer, and even if you have engaged a turn signal, you
must turn the
steering wheel yourself (which cancels Autosteer) to complete a turn
at an intersection.

WARNING: Model 3 also slows down and stops at a roundabout. You must take over steering (which cancels
Autosteer) and press down on the drive stalk or briefly press the accelerator pedal to confirm that you want to
continue through the roundabout.
WARNING: At crosswalks, Model 3 may slow down and may stop, depending on whether the crosswalk is
controlled by a traffic light and whether the cameras detect pedestrians, bicyclists, etc. in the crosswalk. Pay
particular attention at crosswalks and be prepared to take over at any time. Failure to do so can result in injury
or death.
Limitations
Depending on many different circumstances and environmental conditions, Traffic Light and Stop Sign Control may
or may not stop at:

If tires need to be replaced early, for example due to a
flat tire, we recommend replacing the tires in pairs
unless the other tires are within
2/32 in (1.5 mm) of tread
depth of the new tire. When replacing tires, it is important to match the brand and model of the older
tires. Always place a pair of new tires on the rear if all four tires are the same size. Always balance the wheel and tire after replacing a tire. Consult with a professional tire retailer and installer for further guidance.
If you
replace your tires or install different ones, reset the tire
configuration (see Tire Configuration on page 179). This
resets the learned tire settings and improves the driving
experience on your new tires.
NOTE: Regardless of the number of tires replaced, a
complete set of matching tires is recommended for optimum performance.
If tires other than those specified are used, ensure that
the load and speed ratings marked on the tire
(see
Understanding Tire Markings on page 214) equal or
exceed those of the original
specification.
For the specification of the original wheels and tires
installed on
Model 3, see Wheels and Tires on page 213.
If you replace a wheel, the TPMS (Tire Pressure Monitoring System) sensors need to be reset to ensure they provide accurate warnings when tires are under-
or
over-inflated (see Automatic Reset of TPMS Sensors on
page 180).
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. Go to
Service > Wheel & Tire Configuration > Tires to select
winter tires and quicken this process.
WARNING: For your safety, use only tires and
wheels that match the original specification. Tires
that do not match the original specification can
affect the operation of the TPMS.
WARNING: Never exceed the speed rating of your
vehicle
