Canceling and Resuming
To manually cancel Trac-Aware Cruise
Control, briefly push the cruise control lever
away from you or press the brake pedal. The
speedometer icon on the instrument panel
turns gray to indicate that cruise control is not
actively controlling your speed.
To resume cruising at the previously set speed,
briefly pull the cruise control lever toward you.
Note: Depending on date of manufacture,
some Model S vehicles have a button on the
end of the cruise control lever. Pressing this
button when cruise control is active cancels
cruise control.
Note: When
Trac-Aware Cruise Control
cancels, Model S does not coast. Instead,
regenerative braking slows down Model S in
the same way as when you move your foot
o
the accelerator when driving without cruise
control (see Regenerative Braking on page
55).
Warning:
Trac-Aware Cruise Control
cancels, or may not be available, in the
following situations:
• You press the brake pedal.
• Your driving speed drops below
5 mph (8 km/h) in situations when
Model S does not detect a vehicle
ahead within the
specified distance.
• Your driving speed exceeds the
maximum cruising speed of 90 mph
(150 km/h).
• You shift Model S out of Drive.
• The driver's seat belt is unbuckled.
• A door is opened.
• The view from the radar sensor or
camera is obstructed. This could be
caused by dirt, mud, ice, snow, fog,
etc.
• The traction control setting is
manually disabled or is repeatedly
engaging to prevent wheels from
slipping.
• The wheels are spinning while at a
standstill.
• The cruise control system is failing.
• The cruise control system requires
service.
When
Trac-Aware Cruise Control is
unavailable or cancels, Model S no longer
drives consistently at a set speed and no
longer maintains a specified distance
from the vehicle ahead.
Warning: Trac-Aware Cruise Control can
cancel unexpectedly at any time for
unforeseen reasons. Always watch the
road in front of you and stay prepared to
take appropriate action. It is the driver's
responsibility to be in control of Model S
at all times.
Summary of Cruise Indicators
Trac-Aware Cruise Control is
available but is not actively
controlling your speed until you set
the cruising speed. Accelerate until
you reach a desired cruising speed,
then
briefly tap the cruise control
lever up or down (or pull briefly
toward you).
Trac-Aware Cruise Control is
operating and is either maintaining
the set speed (no vehicle in front) or
is maintaining a chosen following
distance from a vehicle in front (up
to the set speed).
Model S has fully stopped behind a
vehicle it was following but an object
is detected in front of Model S,
causing Trac-Aware Cruise Control
to be in a HOLD state. Tap the
accelerator pedal to resume cruising
at the set speed.
Limitations
Trac-Aware Cruise Control is particularly
unlikely to operate as intended in the
following types of situations:
