3-2. Opening, closing and locking the doors
■Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
discharging.
●When the entry function has not been used for 5 days or more
● When the electronic key has been left within approximately 6 ft. (2 m) of the
vehicle for 10 minutes or more
● If the entry function has not been used for 14 days or more, the vehicle can-
not be unlocked by a door other than the driver’s door. To unlock the vehicle,
grip the driver’s door handle or use the wireless remote control or the
mechanical key.
The system will resume operation when...
● The vehicle is locked using the lock sensor when carrying the electronic key
on your person.
● The vehicle is locked/unlocked using the wireless remote control. ( P. 1 1 1 )
● The vehicle is locked/unlocked using the mechanical key. ( P. 581)
■ Conditions affecting operation
P. 1 1 9
■ Notes 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 on the instrument panel, floor or in the 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 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.
● 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 smart key system. (Use the wireless remote control to
unlock the doors.)
● If power slide door is unable to operate due to prohibition by the power slid-
ing door main switch, the door unlock and open operation will not be per-
formed. ( P. 124)

NOTICE
■To prevent damage to the seat
● Avoid putting heavy loads on a folded seat that is being used as a tempo-
rary table.
● Do not sit on or put heavy loads on a second seat that has been removed
from the vehicle. The metal tips of the seat leg may be damaged, prevent-
ing reinstallation of the seat.
● The second seats must be reinstalled in their original positions. If they are
installed in the wrong position, the seat locks or bezels will be damaged.
● Make sure that the path the seat will move through is clear before stowing
or returning the third seat.
● 8-passenger models: Be sure to raise the stowed second center seat
above the outer trim, when removing from the storage box of the luggage
room.
■ Stowing the seat belt
The seat belts and the buckles must be stowed before you fold down the
rear seatbacks.
■ To prevent an ottoman malfunctio n (vehicles with Ottoman seats)
● Do not place any objects in the second passenger footwell that could pre-
vent the operation of the ottoman.
● Do not place heavy luggage on the ottoman.
● Do not place anything under the ottoman when in use. There is a possibil-
ity that something may get caught and cause damage when stowing the
ottoman.
