Forward Collision Warning System

The forward collision warning system (FCWS) feature is for
information only and does not replace your responsibility to
observe all road and driving conditions, abide by all traffic
regulations, and use safe driving judgment at all times. The
FCWS relies on the camera to provide a warning of upcoming
vehicles and, as a result, may have limited functionality in low
visibility conditions. For more information, go to
/warnings.
NOTE: This feature is not available in all areas or for all product
models.
The FCWS feature alerts you when the device detects that you
are not maintaining a safe distance between your vehicle and
the vehicle in front of you. The device determines your vehicle
speed using GPS, and it calculates an estimated safe following
distance based on your speed. The FCWS activates
automatically when your vehicle speed exceeds 48 km/hr
(30 mph).
When the device detects that you are too close to the vehicle
ahead of you, the device plays an audible alert, and a warning
appears on the screen.

Lane Departure Warning System

The lane departure warning system (LDWS) feature is for
information only and does not replace your responsibility to
observe all road and driving conditions, abide by all traffic
regulations, and use safe driving judgment at all times. The
LDWS relies on the camera to provide warnings for lane
markers and, as a result, may have limited functionality in low
visibility conditions. For more information, go to
/warnings.
The LDWS feature alerts you when the device detects you may
be crossing a lane boundary unintentionally. For example, the
device alerts you if you cross some solid painted lane
boundaries or cross into an oncoming traffic lane. The LDWS
feature provides alerts only when your vehicle speed exceeds
64 km/h (40 mph). The alert appears on the left or right side of
the screen to indicate which lane boundary you crossed.
NOTE: For the best LDWS performance, you should set the
Camera Placement option to indicate the location of your device
in the vehicle.

Lane Departure Warning Performance Tips

warning system (LDWS). Some conditions may prevent the
LDWS feature from detecting lane departures.
• The LDWS feature provides alerts only when your vehicle
speed exceeds 65 km/h (40 mph).
• The LDWS feature does not provide alerts on certain types of
roads, such as highway ramps or merging lanes.
• The LDWS feature may not function properly if the camera is
incorrectly aligned.
• The LDWS feature may not function properly if the camera
placement settings do not correctly indicate your vehicle

lane divider lines.
◦ Lane departures may not be detected when divider lines
are obscured by rain, fog, snow, extreme shadows, sun or
headlight glare, road construction, or any other visual
obstruction.
◦ Lane departures may not be detected if lane divider lines
are misaligned, missing, or heavily worn.
