Model X Owner`s Manual

• Visibility is poor and lane markings are not
clearly visible (due to heavy rain, snow,
fog, etc.). The exact detection zone of the
ultrasonic sensors vary depending on
environmental conditions.
• Bright light (oncoming headlights or
direct sunlight) is interfering with the
camera's view.
• A vehicle in front of Model X is blocking
the camera's view.
• The windshield area in the camera's
field
of view is obstructed (fogged over, dirty,
covered by a sticker, etc.).
• Lane markings are excessively worn, have
been adjusted due to road construction,
or are changing quickly (for example,
lanes branching
o, 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
aected by other
electrical equipment or devices that
generate ultrasonic waves.
• An object that is mounted to Model X 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 X
away from an adjacent vehicle, or may apply
unnecessarily or inappropriate steering, if:
• You are driving Model X on sharp corners
or on a curve at a relatively high speed.
• Bright light (oncoming headlights or
direct sunlight) is interfering with the
camera's view.
• 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 X is traveling less than 70 km/h or
over 140 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 aected by other
electrical equipment or devices that
generate ultrasonic waves.
• An object mounted to Model X (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
been adjusted due to road construction or
are changing quickly (for example, lanes
branching
o, 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 Model X so you
can anticipate the need to take corrective
action as early as possible.
Caution: If a fault occurs with the Lane
Assist system, Model X displays an alert.
