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 door will automatically be
locked after approximately 30 seconds if
the doors are not opened and closed.)
If the wireless remote control is used to
●
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 sensor while
●
wearing gloves may delay or prevent lock
operation. Remove the gloves and touch
the lock sensor again.
Some models: When the lock operation
●
is performed using the lock sensor, rec-
ognition signals will be shown up to two
consecutive times. After this, no recogni-
tion signals will be given.
If the door handle becomes wet while the
●
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In that case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 2 m
(6 ft.) 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 entry & start
system. (P.185)
If the electronic key is inside the vehicle
●
and a door handle becomes wet during a
car wash, a message may be shown on
the multi-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.
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.
