assist (vehicles with an intuitive parking assist)
This function detects if there is an obstruction behind the vehicle and reg-
ulates retractable hardtop operation according to the vehicle’s distance
from that obstruction.
This function is merely designed to assist the driver and is not a guarantee
of the safety of the area behind the vehicle. The driver should always
check the vehicle’s surroundings with their own eyes before operating the
retractable hardtop.
■ Operation controls according to each detection area
Area within approximately
1.2 ft. (35 cm) of the vehicle

tion display to alert the driver.
If the switch is held up or down for 3 seconds while the message is being dis-
played, retractable hardtop operation will start normally.
