■Trunk light
The trunk light turns on when the trunk is
opened.
■Function to prevent the trunk being
locked with the electronic key inside
●When both side doors are locked, closing
the trunk lid with the electronic key left
inside the trunk will sound an alarm.
In this case, the trunk lid can be opened
by pressing the trunk release button on
the trunk lid.
●If the spare electronic key is put in the
trunk with both side doors locked, the key
confinement prevention function is acti-
vated so the trunk can be opened. In
order to prevent theft, take all electronic
keys with you when leaving the vehicle.
●If the electronic key is put in the trunk with
both side doors locked, the key may not
be detected depending on the location of
the key and the surrounding radio wave
conditions. In this case, the key confine-
ment prevention function cannot be acti-
vated, causing the trunk to be locked
when the trunk lid is closed. Make sure to
check where the key is before closing the
trunk.
●The key confinement prevention function
cannot be activated if either door is
unlocked. In this case, open the trunk
using the trunk opener switch.
●If the trunk lid is closed by a hand having
the electronic key when the both side
doors are locked, a warning buzzer may
sound. In this case, the trunk is not locked.
Do not close the trunk lid by a hand hav-
ing the electronic key.
■Internal trunk release lever
The trunk lid can be opened by pulling the
glow-in-the-dark lever located on the inside
of the trunk to the side.
The lever will continue to glow for some
time after the trunk lid is closed.
■If the smart access system with push-
button start or the wireless remote con-
trol does not operate properly
Use the trunk opener switch to unlock the
trunk. ( P.359)
Replace the key battery with a new one if it
is depleted. ( P.322)
■If a symbol indicating the trunk opens is
shown on the multi-information display
P.111
■If the 12-volt batte ry is discharged
The trunk cannot be locked and unlocked
using the smart access system with push-
button start or wireless remote control.

1183-2. Opening, closing and locking the doors and trunk
• 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
engine switch
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 possible to start the
engine
key is near the window.
●The doors may unlock or lock if a large
amount of water spla shes 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 d oors 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.)
●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.117)
●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.
●If an outside door handle is not retracted
during a car wash, a door may be opened
or an outside door handle may be dam-
aged. Make sure that the outside door
handles are retracted before using the
car wash.
●A sudden handle operation or a handle
operation immediately after entering the
effective range may prevent the doors
from being unlocked. Touch the door
unlock sensor and check that the doors
are unlocked before pulling the door
handle again.
●Unlocking the vehicle may take more
time if another electronic key is within the
effective range.
■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 access system with push-but-
ton start can be deactivated in advance.
■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 out-
side of the vehicle.
Depending on the position and holding
condition of the elec tronic 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 oper-
ate.)
