handle, such as in the rain or in a car
wash, when the electronic key is within
the effective range. (The doors will auto-
matically be locked after approximately
30 seconds if the doors are not opened
and closed.)

lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock or unlock sensor
while wearing gloves may prevent lock or

using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.

electronic key is within the effective
range, the door may lock and unlock
repeatedly. In this ca se, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle.
