3-2. Opening, closing and locking the doors
lock and unlock repeatedly. In that
case, follow the following correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca-
tion 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
key system. (

P.166)
● 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 vehi-
cle. 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 effec-
tive range or door handle may pre-
vent 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.
● 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.
■ When the vehicle is not driven
for extended periods
● Vehicles with entry function: To
prevent theft of the vehicle, do not
leave the electronic key within 6 ft.
(2 m) of the vehicle.
● The smart key system can be
deactivated in advance. (

● Battery-saving mode can reduce
the power consumption of elec-
tronic keys. (

key when operating the system. Do
not get the electronic key too close
to the vehicle when operating the
system from the outside of the vehi-
cle.
Depending on the position and hold-
ing condition of the electronic key,
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off
accidentally, or the door lock pre-
vention may not operate.)
■ If the smart key system does
not operate properly
