About Driver Assistance
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 on a Model S equipped with the
forward looking camera, you must take
your vehicle to Tesla Service. This will
ensure appropriate handling and
mounting of the camera. Failure to do so
can cause one or more Driver Assistance
features to malfunction.
Cleaning Driver Assistance
Traffic-
Components
To ensure the various Driver Assistance
components can provide information that is as
accurate as possible, keep them clean and free
of obstructions. Occasionally remove any
buildup of dirt by wiping with a soft cloth
dampened with warm water.
Caution: Do not use chemical-based or
abrasive cleaners. Doing so can damage
surfaces.
Caution: Avoid using a high-pressure
power washer.
Caution: Do not clean an ultrasonic sensor
with a sharp or abrasive object that can
scratch or damage its surface.
