You can now release the accelerator pedal and
allow Traffic-Aware Cruise Control to maintain
your set speed. When no vehicle is detected
ahead, Traffic-Aware Cruise Control maintains
the set speed. If a vehicle is detected, Traffic-
Aware Cruise Control maintains your chosen
following distance, up to the set speed,
accelerating and decelerating Model 3 as
needed. When the vehicle you are following is
no longer detected, Traffic-Aware Cruise
Control accelerates up to the set speed.
Traffic-Aware Cruise Control also adjusts the
speed as appropriate when entering and
exiting curves.
You can manually accelerate at any time when
driving at a set speed using Traffic-Aware
Cruise Control. But when you release the
accelerator, Model 3 returns to the set speed.
When following a vehicle, Traffic-Aware Cruise
Control remains active at low speeds, even if
Model 3 comes to a standstill. When the
vehicle is moving again, Traffic-Aware Cruise
Control resumes operating at your current set
speed. However, under certain circumstances,
Traffic-Aware Cruise Control goes into a
HOLD state instead of resuming and the
touchscreen displays a message indicating
that you need to resume cruise control.
Traffic-Aware Cruise Control may go into a
HOLD state under the following
circumstances:
• You have been at a standstill for 5
minutes.
• The driver's seat belt is unbuckled.
• Model 3 detects a pedestrian nearby (the
HOLD state may clear when the
pedestrian is no longer close by).
• Model 3 suddenly loses visibility of the
vehicle you are following.
• The ultrasonic sensors detect an obstacle
in front of Model 3.
To resume Traffic-Aware Cruise Control, press
the accelerator pedal.
Driver Assistance
Traffic-Aware Cruise Control
In right hand traffic, engaging the right turn
signal when driving in the right-most lane
within 164 feet (50 meters) of an exit (on a
controlled access road only, such as a highway
or freeway), causes Traffic-Aware Cruise
Control to assume you are exiting. As a result,
Traffic-Aware Cruise Control begins to slow
down the vehicle. Likewise in left hand traffic,
when engaging the left turn signal when
driving in the left-most lane within 164 feet
(50 meters) of an exit. The onboard GPS
(Global Positioning System) determines if you
are driving in a region with right or left hand
traffic. In situations where GPS data is
unavailable (for example, if there is inadequate
signal), engaging the turn signal near an exit
does not cause Traffic-Aware Cruise Control
to slow down Model 3.
Note: If Traffic-Aware Cruise Control is not
active and you move the gear lever down
twice in quick succession, Autosteer activates
if enabled (see Autosteer
the set speed changes to either your current
driving speed, or remains at the current set
speed (whichever is greater).
Note: When Traffic-Aware Cruise Control is
actively slowing down Model 3 to maintain the
selected distance from the vehicle ahead, the
brake lights turn on to alert other road users
that you are slowing down. You may also
notice slight movement of the brake pedal.
Warning: Due to limitations inherent in
the onboard GPS, you may experience
situations in which Traffic-Aware Cruise
Control slows down the vehicle, especially
near highway exits where a curve is
detected and/or you are actively
navigating to a destination and not
following the route.
Warning: Traffic-Aware Cruise Control
cannot detect all objects and may not
brake/decelerate for stationary vehicles,
especially in situations when you are
driving over 50 mph (80 km/h) and a
vehicle you are following moves out of
your driving path and a stationary vehicle
or object is in front of you instead. Always
pay attention to the road ahead and stay
prepared to take immediate corrective
action. Depending on Traffic-Aware
Cruise Control to avoid a collision can
result in serious injury or death. In
addition, Traffic-Aware Cruise Control
may react to vehicles or objects that
either do not exist or are not in the lane
of travel, causing Model 3 to slow down
unnecessarily or inappropriately.
