used to lock the doors when the
electronic key is near the vehicle,
there is a possib ility that the door
may not be unlocked by the entry
function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock sensor
while wearing gloves may delay or
prevent lock operation. Remove
the gloves and touch the lock sen-
sor again.
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recognition signals will be
