■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affe cting operation
The smart access system with push-button start uses weak radio waves. In the following
situations, the communication between th e electronic key and the vehicle may be
affected, preventing the smart access system with push-button start, wireless remote
control and engine immobilizer system from operating properly.
(Ways of coping: P. 600)

■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 trunk is opened.
• The electronic key is on the instrument pa nel, rear package tray or floor, or in the
door pockets or glove box when the engine is started or engine 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 outside the cabin and the doors 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. However, only the door s detecting the electronic 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 engine
if the electronic key is near the window.
●The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash, when th e electronic key is within the effective range.
(The doors 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 or unlock sensor while wearing gloves may prevent lock or
unlock operation.
●When the lock operation is performed using the lock sensor, recognition signals will be
shown up to two consecutive times. After this, 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 this 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 5 0 )
●If the electronic key is insi de the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the mult i-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock both side 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 handle operation or a handle operation immediately after entering the effec-
tive range may prevent the doors from bein g 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 effec-
tive range.
