not press any buttons on the elec-
tronic key while inside the aircraft 
cabin. If you are carrying an elec-
tronic key in your bag, etc., ensure 
that the buttons are  not likely to be 
pressed accidentally. Pressing a 
button may cause the electronic key 
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.

 even if the
e
lectronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may
 be
de
pleted. Replace the battery
when necessary. ( P.450)
• The smart key system or the wire-
less remote contro l does not oper-

while driving t he vehicle.
Failure to do so m ay result in a 
door opening and an occupant 
being thrown out of the vehicle, 
resulting in death or serious injury.
●Ensure that all doors are prop-
erly closed and locked.
●Do not pull the inside door han-
dle while driving.
Be especially careful of the front 
doors, as the doors may be 
opened even if the inside lock 
buttons are in the locked posi-
tion.
●Set the rear door child-protector 
locks when children are seated 
in the rear seats.
■When opening or closing a 
door
Check the surroundings of the 
vehicle such as whether the vehi-
cle is on an incline, whether there 
is enough space for a door to 
open and whether a strong wind 
is blowing. When opening or clos-
ing the door, hold the door handle 
tightly to prepare for any unpre-
dictable movement.
■When using the wireless 
remote control and operating 
the power windows
Operate the power windows after

is no possibility of any passenger 
having any of their body parts 
caught in the windows. Also, do 
not allow children to operate the 
wireless remote control. It is pos-
sible for children and other pas-
sengers to get caught in the

■Battery-saving function
The battery-saving function will be 
activated in order to prevent the 
electronic key battery and the vehi-
cle battery from being discharged 
while the vehicle is  not operated for 
a long time.
●In the following situations, the 
smart key system may take some 
time to unlock the doors.
• The electronic key has been left 
within approximately 11 ft. (3.5 m) 
of the outside of the vehicle for 2 
minutes or longer.
• The smart key system has not  been used for 5 days or longer.

control and engi ne immobilizer sys-
tem from operating properly.
●When the electronic key battery is 
depleted
●Near a TV tower,  electric power 
plant, gas station, radio station, 
large display, airpo rt or other facil-
ity 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 con-
tact with, or is c overed by the fol-
lowing metallic objects

num 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
●When carrying the electronic key 
together with the following devices 
that emit radio waves
• Another vehicle’s electronic key or 
a wireless key that emits radio 
waves
• Personal computers or personal 
digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic con-
tent or metallic objects are 
attached to the rear window
●When the electronic key is placed 
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a 
pay parking spot where radio 
waves are emitted
If the doors cannot be 
locked/unlocked using the smart key 
system, lock/unlock the doors by 
performing any of the following:
●Bring the electronic key close to 
either front door handle and oper-
ate the entry function.
●Operate the wireless remote con-
trol.
If the doors cannot be 
locked/unlocked using the above 
methods, use the mechanical key. 
(  P.500)
If the engine cannot be started using 
the smart key system, refer to 
P.501.
■Note for the entry function
●Even when the electronic key is 
within the effective range (detec-
tion areas), the system may not 
operate properly in the following  cases:
• The electronic key is too close to  the window or outside door han-
dle, near the ground, or in a high 
place when the doors are locked 
or unlocked.
• The electronic key is on the instru- ment panel, luggage cover 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 out-
side 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 electro nic key is not 
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic 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 effec-
tive 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 possib ility 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.
