Retractable hardtop operation control linked to the intuitive parking
assist (vehicles with an intuitive parking assist)
This function detects if there is an ob struction behind the vehicle and reg-
ulates retractable hardtop operation according to the vehicle’s distance
from that obstruction.
This function is merely de signed to assist the driver and is not a guarantee
of the safety of the ar ea 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
Area approximately
1.2 ft. (35 cm) to 1.5 ft. (45 cm)
away from the vehicle
Areas within approximately
0.8 ft. (25 cm) of the vehicle
Areas approximately
0.8 ft. (25 cm) to 1.3 ft. (37.5
cm) away from the vehicle
This function only operates in the
areas indicated in the illustration.
Therefore, obstructions too close
to the sensors cannot be detected.
●If an obstruction is d etected in area or when the switch is oper-
ated
A buzzer will sound and a message will be shown in the multi-informa-
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.

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather
In addition to the examples above, there are instances in which, because of their
shapes, signs and other object s may be judged by the sensor to be closer than they
are.
●The shape of the obstacle may prevent th e sensor from detecting it. Pay particu-
lar attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle
