■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the follow-
ing 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 engine immobilizer system from operating prop-
erly. (Ways of coping: →P. 6 7 7 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
●When the electronic key is in contact with, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that emit radio waves) are being used nearby

Operation of each component
■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 panel, rear package tray or floor, or in the door pockets or glove box when the engine is started or
“START STOP ENGINE” <“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 reception condi-
tions, 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 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 am ount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the effec-
tive 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 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.)

■Note for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent lock
operation. Remove the gloves and touch the lock sensor again.
●If the door handle becomes wet while the electronic 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 sys- tem with push-button start. (→ P. 1 3 3 )
●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.
●Fingernails may scrape against the door during operation of the door handle. Be
careful not to injure fingernails or damage the surface of the door.
■Note for the unlocking function
●A sudden approach to the effective range or door handle may prevent 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.
●Gripping the door handle when wearing a glove may not unlock the door.
●If the door handle becomes wet while the electronic 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 sys- tem with push-button start. (→ P. 1 3 3 )
●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.
●Fingernails may scrape against the door during operation of the door handle. Be
careful not to injure fingernails or damage the surface of the door.
