Before driving
●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.530)
If the engine cannot be started using
the smart key system, refer to
P.531.
■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 compartment
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 electronic 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 possibilit y that the door
may not be unlocked by the entry
function. (Use the wireless remote
control to unlock the doors.)
●If the doors have been locked
from outside of the vehicle and are
then not unlocked using the wire-
less remote control or smart key
system, the engine cannot be
started using the smart key sys-
tem. (However, if the doors have
been locked from inside the vehi-
cle, the engine can be started
using the smart key system.)
If it is necessary to start the
engine, it can be started using the
procedure in “If the electronic key
dose not operate properly”
