Electronic Key battery-Saving Function
When battery-saving mode is set, battery de pletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■
Conditions affe cting operation
The smart access system with push-button star t, wireless remote control and immobilizer
system use weak radio waves. In the followi ng situations, the communication between the
electronic key and the vehicle may be affected, preventing the smart access system with
push-button start, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping: P. 5 9 2 )●

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 room, 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 th e instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be
detected by the antenna outs ide the cabin and the door will become lockable from the
outside, possibly trapping the el ectronic key inside the vehicle.●
As long as the electronic key is within the effective range, the doors may be locked or
unlocked by anyone. ●
Even if the electronic key is not inside the ve hicle, it may be possible to start the hybrid
system if the electronic key is near the window. ●
The doors may unlock if a large amount of wa ter 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 60 seconds if the doors are not
opened and closed.) ●
If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the door may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.) ●
Touching the door lock sensor while wearin g gloves may delay or prevent lock opera-
tion. Remove the gloves and touch the lock sensor again. ●
When the lock operation is performed using the lock sensor, recognition signals will be
shown up to two consecutive times. After th is, no recognition signals will be given. ●
If the door handle becomes wet while the el ectronic key is within the effective 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 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 access system
with push-button start. ( P. 1 4 2 )●
