■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
been locked/unlocked. (Locked: Once; Unlocked: Twice)
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start from
operating properly:

●Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices
●When the electronic key is in contact with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When another wireless key (that emits radio waves) is being used nearby
●When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle's electronic key or a wireless key that emits radio waves
• Personal computer or personal digital assistant (PDA)
• Digital audio player

Retractable hardtop operation control linked to the intuitive parking
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
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 detected 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.
