Conditions affecting operation
The smart key system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and immobilizer
system from operating properly. (Ways of coping: P. 398)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
● 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
● When carrying the electronic key together with the following devices that
emit radio waves
• Portable radio, cellular phone, cordless phone or other wireless commu-
nication devices
• 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 content or metallic objects are attached to the
rear window
● When the electronic key is placed near a battery charger or electronic
devices

Operation of each component
MIRAI_OM_USA_OM62004U■
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 fuel cell system is started or
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 recep-
tion conditions, 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 elec-
tronic 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 fuel cell system 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 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.)
● 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 sig-
nals 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 effec-
tive 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 key
system. ( P. 133)
● 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 dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.
1364-2. Opening, closing and locking the doors
MIRAI_OM_USA_OM62004U●
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 from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
● 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.
■ When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m)
of the vehicle.
● The smart key system can be deactivated in advance. ( P. 436)
■ To operate the system properly
●Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention function may not
operate.)
● Do not leave the electronic key inside the trunk.
The key confinement prevention function may not operate, depending on
the location of the key (close to the emergency tire puncture repair kit, the
inside edge of the trunk), conditions (inside a metal bag, close to metallic
objects) and the radio waves in the surrounding area. ( P. 128)
■ If the smart key system do es not operate properly
● Locking and unlocking the doors and opening the trunk:
Use the mechanical key. ( P. 398)
● Starting the fuel cell system: P. 399
■ Customization
Settings (e. g. smart key system) can be changed.
(Customizable features: P. 436)
■ If the smart key system has been deactivated in a customized setting
●Locking and unlocking the doors and opening the trunk:
Use the wireless remote control or mechanical key. ( P. 120, 126, 398)
● Starting the fuel cell system and changing power switch modes: P. 399
● Stopping the fuel cell system: P. 173

■The wireless charger can be operated when
The power switch is in ACCESSORY or ON mode.
■ Usable portable devices
Qi standard wireless charge standard can be used on compatible devices.
However, not all Qi standard devices and compatibility are guaranteed.
Starting with mobile phones and smart phones, it is aimed for low power elec-
trically supplied portable devices of no more than 5 W.
■ When covers and accessories are attached to portable devices
Do not charge in situations where cover and accessories not able to handle
Qi are attached to the portable device. Depending on the type of cover and
accessory, it may not be possible to charge. When charging is not performed
even with the portable device placed on the charge area, remove the cover
and accessories.
■ While charging, noise enters the AM radio
Turn off the wireless charger and confirm that the noise has decreased. If the
noise decreases, continuously pushing the power supply switch of the wire-
less charger for 2 seconds, the frequency of the charger can be changed and
the noise can be reduced.
Also, on that occasion, the operation indicator light will flash orange 2 times.
■ Important points of the wireless charger
●If the electronic key cannot be detected within the vehicle interior, charging
cannot be done. When the door is opened and closed, charging may be
temporarily suspended.
● When charging, the wireless charging device and portable device will get
warmer, however this is not a malfunction.
When a portable device gets warm while charging, charging may stop due
to the protection function on the portable device side. In this case, when the
temperature of the portable device drops significantly, charge again.
■ Operation sounds
When the power supply is turned on, while searching for the portable device a
sound will be produced, however this is not a malfunction.
