■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 unl ocked.
• The electronic key is near the ground or in a high place, or t oo close to
the rear bumper center when the trunk is opened.
• The electronic key is on the instrument panel or floor, or in the console
box or glove box when the engine is started or engine switch mo des 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 w ave recep-
tion 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.

locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.

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 lo cked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when t he electronic
key is near the vehicle, there is a possibility that the door m ay not be
unlocked by the entry function. (Use the wireless remote contro l to unlock
the doors.)
● Touching the door lock or unlock sensor while wearing gloves ma y prevent
lock or unlock operation. Remove the gloves and touch the lock sensor
again.
● When the lock operation is performed using the lock sensor, rec ognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.

tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more awa y from the
vehicle. (Take care to ensure that the key is not stolen.)
