■ Electronic key battery depletion
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin when the hybrid
system stops.
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( P. 459)
• The smart entry & start system, push button start or the wireless remote
control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appliances that produce a magnetic field.
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones

1383-2. Opening, closing and locking the doors
UK AURIS_HV_HB_EE (OM12M49E)
■ Note for the entry function
● 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 back door is opened.
• The electronic key is on the instrument panel, luggage cover or floor, or in
the door pockets or glove box when the hybrid system is started or power
switch modes are changed.
● 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 recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door 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 elec-
tronic key can be used to unlock the vehicle.
● Even if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.
● 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.
● When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following 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. 136)
