Lane Assist
• 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 X is not traveling within the speeds at which
the Lane Assist feature is designed to operate.
• One or more of the ultrasonic sensors is damaged,
dirty, or obstructed (such as by mud, ice, or snow, or
by a vehicle bra, excessive paint, or adhesive
products such as wraps, stickers, rubber coating,
etc.).
• 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 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 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 features. There are many reasons why Lane
Assist may not operate as intended. To avoid a
collision, stay alert and always pay attention to
the roadway so you can anticipate the need to
take corrective action as early as possible.
