WARNING: Do not rely on Trac-Aware Cruise
Control or Speed Assist to determine an accurate
or appropriate cruising speed. It is the driver's
responsibility to cruise at a safe speed based on
road conditions and applicable speed limits.
Changing the Cruising Speed
Roll the right scroll wheel up to increase, or down to
decrease, the set speed. Slowly rolling the scroll wheel
changes the set speed in
1 mph (1 km/h) increments
and quickly rolling the scroll wheel changes the set
speed to the closest 5 mph (5 km/h) increment.
You can also use the touchscreen to change the set
cruising speed:
•
To adjust the cruising speed to your current driving
speed, touch the speedometer icon.
•
To adjust the cruising speed to the speed limit (plus
any oset you've specified using Speed Assist),
touch the speed limit icon (if displayed).
•
Touch plus (+) or minus (-) next to the set cruising
speed icon. A quick tap changes the set speed by
1 mph (1 km/h) and a press and hold changes the set
speed to the closest 5 mph (5 km/h) increment. To
increase/decrease to the next increment, you must
release the plus (
+) or minus (-) then press it again.
NOTE:
It may take a few seconds for Model 3 to reach
the new cruising speed, assuming Model 3 does not
detect a vehicle ahead driving slower than your set
speed.
Cruising at the Set Speed
Trac-Aware Cruise Control maintains your set cruising
speed whenever a vehicle is not detected in front of
Model 3. When cruising behind a detected vehicle,
Trac-Aware Cruise Control accelerates and
decelerates Model 3 as needed to maintain a chosen
following distance (see Adjust the Following Distance
on page 85), up to the set speed.
Trac-Aware Cruise Control also adjusts the cruising
speed when entering and exiting curves.
You can manually accelerate at any time when cruising
at a set speed, but when you release the accelerator,
Trac-Aware Cruise Control resumes cruising at the set
speed.
NOTE: When Trac-Aware Cruise Control is actively
slowing down
Model 3 to maintain the selected
distance from the vehicle ahead, brake lights turn on to
alert other road users that you are slowing down. You
may notice slight movement of the brake pedal.
However, when Trac-Aware Cruise Control is
accelerating
Model 3, the accelerator pedal does not
move.
WARNING:
Trac-Aware Cruise Control may
occasionally cause Model 3 to brake when not
required or when you are not expecting it. This
can be caused by closely following a vehicle
ahead, detecting vehicles or objects in adjacent
lanes (especially on curves), etc.
WARNING:
Due to limitations inherent in the
onboard GPS (Global Positioning System), you
may experience situations in which Trac-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:
Trac-Aware Cruise Control cannot
detect all objects and, especially in situations
when you are driving over 50 mph (80 km/h),
may not brake/decelerate when a vehicle or
object is only partially in the driving lane or when
a vehicle you are following moves out of your
driving path and a stationary or slow-moving
vehicle or object is in front of you. Always pay
attention to the road ahead and stay prepared to
take immediate corrective action. Depending on
Trac-Aware Cruise Control to avoid a collision
can result in serious injury or death. In addition,
Trac-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.
