Operation of each component
■Note 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 near the ground or in a high place, or too close to the rear
bumper center when the trunk is opened.
• The electronic key is on the instrument pa nel, rear package tray or floor, or in the
door pockets or glove box when the engine is started or engine switch modes are
changed.
●Do not leave the electronic key on top of th e 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 doors will become lockable from the
outside, possibly trapping the el ectronic 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 door s detecting the electronic key can be used
to unlock the vehicle.
●Even if the electronic key is not inside the vehicle, it may be possible to start the engine
if the electronic key is near the window.
●The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash when th e 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 lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the door may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or
unlock operation.
●If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correction
procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle. (Take
care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart access system with push-button start. ( P. 1 0 8 )
●If the electronic key is insi de the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the mult i-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc.
Clean the lock sensor and attempt to operate it again, or use the lock sensor on the
lower part of the door handle.
●A sudden approach to the effective range or door handle may prevent the doors from
being unlocked. In this case, return the door handle to the original position and check
that the doors unlock before pulling the door handle again.
●Gripping the door handle when wearing a glove may not unlock the door.
●If there is another electronic key in the detection area, it may take slightly longer to
unlock the doors after the door handle is gripped.
