Autosteer
NOTE: Auto Lane Change assists in moving
Model 3 one lane at a time. Moving into an
additional lane requires you to engage the
turn signal a second time after the first lane
change is complete.
Operating Auto Lane Change
Auto Lane Change is available whenever
Autosteer is active. To change lanes using
Auto Lane Change:
When using Auto Lane Change, it is
1. Perform visual checks to make sure it is
safe and appropriate to move into the
target lane
important to monitor its performance by
watching the driving path in front of you and
the surrounding area. Stay prepared to take
over steering at any time. As you are crossing
over into the adjacent lane, the touchscreen
displays the lane marking as a dashed blue
line. Once in your new lane, lane markings are
displayed as solid blue lines again.
2. Fully engage the appropriate turn signal
and initiate the lane change by having
your hands on the steering wheel.
3. Disengage the turn signal after you are in
the target lane.
In situations where Auto Lane Change is
unable to operate at optimal performance, or
cannot operate due to inadequate data, the
touchscreen displays a series of warnings.
Therefore, when using Auto Lane Change,
always pay attention to the touchscreen and
be prepared to manually steer Model 3.
NOTE: Auto Lane Change cancels if the lane
change cannot be completed in five seconds.
Auto Lane Change assists in moving Model 3
into the adjacent lane in the direction
indicated by the turn signal, provided the
following conditions are met:
Stop Light and Stop Sign
Warning
• Auto Lane Change detected your hands
on the steering wheel.
• The turn signal is fully engaged.
NOTE: Depending on market region, vehicle
configuration, options purchased, and
software version, your vehicle may not be
equipped with Stop Light and Stop Sign
Warning.
• The ultrasonic sensors and Autopilot
cameras do not detect a vehicle or
obstacle up to the center of the target
lane.
• The lane markings indicate that a lane
change is permitted.
While Autosteer is in use, Model 3 displays a
warning on the touchscreen and sounds a
chime if it detects that you are likely to run
through a red stop light or stop sign. If this
happens, TAKE IMMEDIATE CORRECTIVE
ACTION!
• The view of the camera(s) is not
obstructed.
• Your vehicle does not detect another
vehicle in its blind spot.
The visual and audible warnings cancel after a
few seconds, or when you press the brake
pedal, whichever comes first.
• Midway through the lane change, Auto
Lane Change can detect the outside lane
marking of the target lane.
• Driving speed is at least 30 mph
(45 km/h).
Stop Light and Stop Sign Warning provides
warnings only. It makes no attempt to slow
down or stop Model 3 at red traffic lights,
stop signs, road markings, etc. If your vehicle
is equipped with Traffic Light and Stop Sign
Control, you can enable this feature to
automatically stop Model 3 at traffic lights
and stop signs (see Traffic Light and Stop
Sign Control on page 124).
As the lane change is in progress, Overtake
Acceleration is activated, allowing Model 3 to
accelerate closer to a vehicle in front (see
Overtake Acceleration on page 113). Midway
through the lane change, Auto Lane Change
must detect the target lane's outside lane
marking. If this lane marking cannot be
detected, the lane change is aborted and
Model 3 returns to its original driving lane.
