• The windshield is obstructing the view of
the camera(s) (fogged over, dirty, covered
by a sticker, etc.).
• Lane markings are excessively worn, have
visible previous markings, have been
adjusted due to road construction, or are
changing quickly (for example, lanes
branching off, crossing over, or merging).
• The road is narrow or winding.
• Objects or landscape features are casting
strong shadows on lane markers.
Lane Assist may not provide warnings, or may
apply inappropriate warnings, in these
situations:
• One or more of the ultrasonic sensors is
damaged, dirty, or obstructed (such as by
mud, ice, or snow).
• Weather conditions (heavy rain, snow,
fog, or extremely hot or cold
temperatures) are interfering with sensor
operation.
• The sensors are affected by other
electrical equipment or devices that
generate ultrasonic waves.
• An object that is mounted to Model S is
interfering with and/or obstructing a
sensor (such as a bike rack or a bumper
sticker).
In addition, Lane Assist may not steer Model S
away from an adjacent vehicle, or may apply
unnecessary or inappropriate steering, in
these situations:
• You are driving Model S on sharp corners
or on a curve at a relatively high speed.
• Bright light (such as from oncoming
headlights or direct sunlight) is interfering
with the view of the camera(s).
• You are drifting into another lane but an
object (such as a vehicle) is not present.
• A vehicle in another lane cuts in front of
you or drifts into your driving lane.
• Model S is traveling less than 48 km/h or
over 145 km/h.
• One or more of the ultrasonic sensors is
damaged, dirty, or obstructed (such as by
mud, ice, or snow).
• Weather conditions (heavy rain, snow,
fog, or extremely hot or cold
temperatures) are interfering with sensor
operation.
• The sensors are affected by other
electrical equipment or devices that
generate ultrasonic waves.
• An object mounted to Model S (such as a
bike rack or a bumper sticker) is
interfering with or obstructing a sensor.
• Visibility is poor and lane markings are
not clearly visible (due to heavy rain,
snow, fog, etc.).
• Lane markings are excessively worn, have
visible previous markings, have been
adjusted due to road construction or are
changing quickly (for example, lanes
branching off, crossing over, or merging).
WARNING:
The lists above do not
represent every possible situation that
may interfere with Lane Assist
warnings. Lane Assist may not operate
as intended for many other reasons.
To avoid a collision, stay alert and
always pay attention to the roadway
when driving so you can anticipate the
need to take corrective action as early
as possible.
