■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 compartment, floor, or in thedoor 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 door will become lockable from theoutside, possibly trapping the electronic key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be locked orunlocked by anyone.
●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 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 approx imately 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 d oor 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 to uch 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 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 sys-
tem. ( P. 170)
●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 mult i-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.
●A sudden approach to the effective range or door handle may prevent the doors frombeing unlocked. In this case, return the door  handle to the original position and check that the doors unlock before pulling the door handle again.
●If there is another electronic key in the de tection area, it may take slightly longer to unlock the doors after the door handle is gripped. 
●Fingernails may scrape against the door duri ng operation of the door handle. Be care- 
ful not to injure fingernails or damage the surface of the door.
