The parking assist monitor assists with the following 2 backing-up
operations:
• Perpendicular parking (parking in a garage, etc.)
• Parallel parking (parking at the side of the road, etc.)
The screen illustrations used in this text are intended as examples, and
may differ from the image that is actually displayed on the screen.
Parking assist monitor will acti-
vate when the shift lever is in R.
If you move the lever out of R, the
parking assist monitor will be

the parking assist monitor is can-
celed, and the screen is switched to
the mode of the button that was
pressed.
The parking assist monitor assists the driver by displaying an
image of the view behind the vehicle while backing up, for exam-
ple while parking.
