• 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

If the doors cannot be locked/unlocked
using the smart en try & start system,
lock/unlock the doors by performing any of the following (vehicles with entry func-
tion):
●Bring the electronic key close to either
front door handle and operate the
entry function.
●Operate the wireless remote control.
If the doors cannot be locked/unlocked
using the above methods, use the mechanical key. ( P.512)
If the engine cannot be started using the
smart entry & start system refer to P.512.
■Note for the entr y function (if
equipped)
●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
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 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 elec-
tronic key inside the vehicle.
●As long as the electronic key is within
the effective range, the doors may be locked or unlocked by anyone. How-
ever, 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 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 30 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 pos- sibility that the door may not be
unlocked by the entry function. (Use
the wireless remote control to unlock the doors.)
