1523-2. Opening, closing and locking the doors and trunk
IS300h_EE(OM53B95E)
Note for the entry function (if equipped)
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 unlocked.
• The electronic key is near the ground or in a high place, or too close to the
rear bumper center when the trunk is opened.
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 wave reception con-
ditions, it may be detected by the antenna outside the cabin and the doors will
become lockable from the outside, possibly trapping the electronic key inside
the vehicle.
As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the electronic
key can be used to unlock the vehicle.
The doors may unlock or lock if a large amount 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 doors 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 or unlock sensor while wearing gloves may prevent
lock or unlock operation.
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In this 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 vehi-
cle. (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. 150)
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, or use the lock
sensor on the lower part of the door handle.
A sudden handle operation or a handle operation immediately after entering the
effective range may prevent the doors from being unlocked. Touch the door
unlock sensor and check that the doors are unlocked before pulling the door
handle again.
Unlocking the vehicle may take more time if another electronic key is within
the effective range.
