• You shift Model S into a dierent gear.
• 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 Trac-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: 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.
Summary of Cruise Indicators
Trac-Aware
Cruise
Control is available but is
not actively controlling
your speed until you
activate it. The number
shown in gray is
determined by Speed
Assist (see
Controlling
Speed Assist on page
124).
Trac-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 ahead (up to the
set speed).
Model S
has fully stopped
but is in a HOLD state. If
safe, press the accelerator
pedal to resume cruising
at the set speed.

unlikely to operate as intended in the
following types of situations:
•
The road has sharp curves.
•
Visibility is poor (due to heavy rain, snow,
fog, etc.).
•
Bright light (such as from oncoming
headlights or direct sunlight) is interfering
with the view of the camera(s).
•
The radar sensor is obstructed (dirty,
covered, etc.).
•
The windshield is obstructing the view of
the camera(s) (fogged over, dirty, covered
by a sticker, etc.).

represent an exhaustive list of
situations that may interfere with
proper operation of Trac-Aware
Cruise Control.
