Note: When

specified distance.
• Your driving speed exceeds the
maximum cruising speed of 90 mph
(150 km/h).
• You shift Model S into a
dierent
gear.
• The driver's seat belt is unbuckled.
• A door is opened.
• The view from the radar sensor or
camera(s) 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
Trac-Aware Cruise Control
system is failing or requires service.
When

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:
Trac-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.
