■System maintenance
The vehicle has a maintenance-free
type immobilizer system.
■Conditions that may cause the
system to malfunction
●If the grip portion of the key is in
contact with a metallic object
●If the key is in close proximity to or

tem (key with a built-in transpon-
der chip) of another vehicle
■Certification
 P.543
Immobilizer system
The vehicle’s keys have
built-in transponder chips
that prevent the fuel cell
system from starting if a key
has not been previously
registered in the vehicle’s
on-board computer.
Never leave the keys inside
the vehicle when you leave
the vehicle.
This system is designed to
help prevent vehicle theft
but does not guarantee
absolute security against all
vehicle thefts.
Operating the system
NOTICE
■To ensure the system oper-
ates correctly
Do not modify or remove the sys-
tem. If modified or removed, the
proper operation of the system
cannot be guaranteed.

1324-2. Opening, closing and locking the doors and trunk
Owners Manual_USA_M62084_en
●Electronic keys that will not be
used for long periods of time can
be set to the battery-saving mode
in advance.
■Conditions affecting operation
The smart key system uses weak
radio waves. In the following situa-
tions, 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.468)
●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 covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is
attached
• Cigarette boxes that have alumi- 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 electronic key or a wire- less key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint wit h 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.
■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 near the ground or in a high place, or too
close to the center of the rear
bumper when the trunk is opened.
• The electronic key is on the instru- ment panel, rear package tray or
floor, or in the door pockets or
glove box when the fuel cell sys-
tem 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 reception conditions, it may
be detected by the antenna out-
side the cabin and the doors 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
