Parking Aids 231
If your vehicle is equipped with active guidelines they are only shown
with fixed guidelines. To use active guidelines, turn the steering wheel to
point the guidelines toward an intended path. If the steering wheel
position is changed while reversing, the vehicle might deviate from the
original intended path.
The fixed and active guidelines fade in and out depending on the
steering wheel position. When the steering wheel position is straight, the
active guidelines are not shown.
Always use caution while reversing. Objects in the red zone are closest
to your vehicle and objects in the green zone are further away. Objects
are getting closer to your vehicle as they move from the green zone to
the yellow or red zones. Use the side view mirrors and rear view mirror
to get better coverage on both sides and rear of the vehicle.
Selectable settings for this feature are ACTIVE + FIXED, FIXED and
OFF.
Visual Park Aid Alert
Note: Visual park alert is only available when the transmission is in R
(Reverse).
Note: The reverse sensing system is not effective at speeds above 3 mph
(5 km/h) and may not detect certain angular or moving objects.
The visual park aid alert allows the driver to view the area that is being
detected by the reverse sensing system. The system uses red, yellow and
green highlights which appear on top of the video image when an object
is detected by the reverse sensing system. The alert highlights the
closest object detected. The reverse sensing alert can be disabled and if
visual park aid alert is enabled, highlighted areas are still displayed.
Selectable settings for this feature are ON and OFF.
