Features
These safety features are available on all Tesla
vehicles equipped with Driver Assistance
components:
• Lane Assist (see Lane Assist on page
91).
• Collision Avoidance Assist (see Collision
Avoidance Assist on page 93).
• Speed Assist (see Speed Assist on page
97).
• Auto High Beam (see High Beam
Headlights on page 56).
These convenience features, designed to
reduce driver workload, are available only if
your Tesla vehicle is equipped with the
optional Enhanced Autopilot or Full Self-
Driving Capability packages:
•
Trac-Aware Cruise Control (see Trac-
Aware
Cruise Control on page 76).
• Autosteer (see Autosteer on page 82).
• Auto Lane Change (see Auto Lane
Change on page 85).
• Autopark (see Autopark on page 87).
You can enable/disable Driver Assistance
features and in some cases, control how they
work. To access settings for Driver Assistance
features, touch Controls > Settings > Driver
Assistance.
Calibration
Model S must maneuver with a great deal of
precision when Driver Assistance features are
being used. Therefore, before some features
(for example,
Trac-Aware Cruise Control or
Autosteer) can be used for the first time,
some cameras must complete a self-
calibration process.
Calibration typically completes after driving
32-40 km, but the distance varies depending
on road and environmental conditions. Driving
on a straight road with highly-visible lane lines
allows Model S to calibrate quicker. When
calibration is complete, the features are
available for use the next time you drive (i.e.
you must stop and shift into Park before you
can use the features). Contact Tesla if your
Model S has not completed the calibration
process after driving 160 km.
Note: If you attempt to use a feature that is
not available until the calibration process is
complete, the feature will not be enabled and
the instrument panel displays a message.
Note:
Model S repeats the calibration process
if the cameras are serviced by Tesla and in
some cases, after a software update.
Limitations
Many factors can impact the performance of
Driver Assistance components, causing them
to be unable to function as intended. These
include (but are not limited to):
• Poor visibility (due to heavy rain, snow,
fog, etc.).
• Bright light (due to oncoming headlights,
direct sunlight, etc.).
• Damage or obstructions caused by mud,
ice, snow, etc.
• Interference or obstruction by object(s)
mounted onto the vehicle (such as a bike
rack).
• Obstruction caused by applying excessive
paint or adhesive products (such as
wraps, stickers, rubber coating, etc.) onto
the vehicle.
• Narrow or winding roads.
• A damaged or misaligned bumper.
• Interference from other equipment that
generates ultrasonic waves.
• Extremely hot or cold temperatures.
Warning: The list above does not
represent an exhaustive list of situations
that may interfere with proper operation
of Driver Assistance components. Never
depend on these components to keep
you safe. It is the driver's responsibility to
stay alert, drive safely, and be in control
of the vehicle at all times.
Caution: If a windshield replacement is
needed, take your vehicle to Tesla
Service. This will ensure appropriate
handling and mounting of the camera(s).
Failure to do so can cause one or more
Driver Assistance features to malfunction.
Cleaning Cameras and Sensors
To ensure the various Driver Assistance
components can provide information that is as
accurate as possible, keep them clean and free
of obstructions or damage. Occasionally
remove any buildup of dirt by wiping the
components with a soft cloth dampened with
warm water.
Caution:
Do not use chemical-based or
abrasive cleaners. Doing so can damage
surfaces.
