When a red frame is displayed in the
assist mode
If the frame turns red and the message
“Adjust the frame to the target.” is dis-
played while setting the target parking
position, you cannot use the assist mode.
In this situation, move the target parking
position, or move the position of the ve-
hicle.
The frame may be displayed in red, de-
pending on the location and angle of the
vehicle when “R” is selected.
Furthermore, even if the frame is displayed
in green, if you move the frame to a loca-
tion unsuitable for parking using the assist
mode, the frame will change to red.
When in the parking assist mode, if the
message “Steer to left (right) until the
frame becomes green.” is displayed, you
may use the assist mode by turning the
steering wheel. 1. Align
the frame with the target park-
ing position.
2. While stopped, turn the wheel to the
left (right) until the frame turns green
and “Too much force applied to the
steering wheel.” is displayed.
Turn the wheel slightly more than neces-
sary to overcome tire resistance.
If you turn the wheel too far, the direction
of turn displayed on the screen will re-
verse.
3. Touch “OK”.
Once you have turned the steering wheel,
you can no longer change the target park-
ing position. Be sure to align the frame be-
fore turning the steering wheel.
