●
If window tint with a metallic content or metallic objects are attached to
the rear window
● Vehicles with AUTO ACCESS SEAT: If the wireless remote control of the
AUTO ACCESS SEAT is operated simultaneously, the AUTO ACCESS
SEAT may not operate properly.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.
■ Notes for the entry function
● Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel, floor or in the glove box when the engine is started or “ENGINE START STOP” switch modes
are changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave
reception conditions, it may be detected by the antenna outside the cabin
and the door will become lockable from the outside, possibly trapping the
electronic key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone. However, only the doors detecting the
electronic key can be used to unlock the vehicle.
● The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash when the electronic key
is within the effective range. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the smart key system. (Use the wireless remote control to
unlock the doors.)
● If power slide door is unable to operate due to prohibition by the power
sliding door main switch, the door unlock and open operation will not be
performed. ( P. 70)
