3-1.Key information
The following keys are provided with 
the vehicle.
Electronic keys
• Operating the smart access system with push-button start ( 
P.93)
• Operating the wireless remote control  function ( 
P.84)
Mechanical keys
Key number plate
Card key (electronic key) (if 
equipped)
Operating the smart access system with 
push-button start ( P.93)
■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that  is stored inside 
the card key should be used only if a 
problem arises, such as when the card  key does not operate properly.
●If it is difficult to take out the mechanical 
key, push down the lock release button 
using a pen tip etc. If it is still difficult to 
pull it out, use a coin etc.
●To store the mechanical key in the card 
key, insert it while pressing the lock 
release button.
●If the battery cover is not installed and the 
battery falls out or if the battery was 
removed because the key got wet, rein-
stall the battery with the positive terminal

■When riding in an aircraft
When bringing an electronic key onto an 
aircraft, make sure you do not press any 
buttons on the electronic key while inside 
the aircraft cabin. If you are carrying an 
electronic key in your bag etc., ensure that 
the buttons are not likely to be pressed acci-
dentally. Pressing a button may cause the 
electronic key to emit radio waves that 
could interfere with the operation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. 
(The card key battery life is about a year 
and a half.)
●If the battery becomes low, an alarm will 
sound in the cabin and a message will be 
shown on the multi-information display

window
●When the electronic key is placed near a 
battery charger or electronic devices
■Note for the entry function
●Even when the electronic key is within the 
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win- dow 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 engine 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 
conditions, it may be  detected by the 
antenna outside the cabin and the doors 
will become lockable from the outside, 
possibly trapping the electronic key 
inside the vehicle.
●As long as the electron ic 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 po ssible to start the 
engine 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 auto-
matically 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.)
●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 
electronic key is within the effective 
range, the door may lock and unlock 
repeatedly. In this case, follow the follow-
ing 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.94)
●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 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.
