Park AssistHow Park Assist Works
If Model S is equipped with the Park Assist
option, both the front and rear bumpers include
four sensors. When moving slowly in Drive or
Reverse, the sensors alert you if an object is
detected close to the front or rear bumper,
respectively.
When driving less than 4.8 km/h, the sensors
are activated.
WARNING: Never depend on Park Assist
to inform you if an area you are
approaching is free of objects and/or people.
Several external factors can reduce the
performance of Park Assist, causing either no
readings or false readings (see page 4.17).
Therefore, depending on Park Assist to
determine if Model S is approaching an
obstruction can result in damage to the vehicle
and/or objects, and can cause serious injury to
people. Always inspect the area with your own
eyes. When reversing, perform shoulder checks
and use all mirrors. Park assist does not detect
children, pedestrians, bicyclists, animals, or objects that are moving, protruding, located
too far above or below the sensors, or too close
or too far from the sensors. Park Assist is for
guidance purposes only and is not intended to
replace your own direct visual checks for
obstructions or objects. It is not a substitute for
careful driving.
Visual and Audio Feedback
Whenever Model S is moving slowly in Reverse
or Drive at a speed of less than 4.8 km/h, the
left side of the instrument panel provides
feedback to alert you if an object is detected
near the corresponding back or front bumper.
When reversing, visual feedback also displays
on the touchscreen, immediately below the
camera view (see page 4.24).
If chimes are turned on (see page 4.17), an
audible beep sounds as you approach an
object. You can temporarily mute the chime by
pressing the scroll wheel on the left side of the
steering wheel.
Model S detects an
object within about
120 cm in Drive, and
about 160 cm of the
rear bumper in Reverse.
The chime starts to
beep (if enabled).
As Model S moves
closer to the object, the
yellow zone and the
approximate distance
from the object
displays.
When Model S detects
the object within about
40 cm of the front
bumper in Drive, and
about 30 cm of the rear
bumper in Reverse, the
red zone and a stop
advisory displays. The
chime’s beep changes to
a higher pitch.
If a sensor is unable to provide feedback, the
instrument panel displays an alert message.
