Failure to do so may result in death or serious injury.
● Do not leave children alone in the vehicle.
If a child is accidentally locked in the vehicle, they could have heat
exhaustion or other injuries.
● Do not allow a child to open or close the sliding door.
Doing so may cause the sliding door to move unexpectedly, or cause the
child’s hands, head, or neck to be caught by the moving sliding door.
■ Operating the sliding doors

Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
● When opening or closing a sliding door, thoroughly check to make sure the
surrounding area is safe.

on.
Failure to do so may cause death or serious injury.
● When using the door handle to open or close the power sliding door,
remove your hand from the door handle immediately after starting power
sliding door operation. If you leave your hand on the door handle during
operation, your hand, fingers, wrist etc. may be subjected to an excessive
amount of force.

buzzer may sound and the sliding door may stop opening or closing. The
sliding door then has to be operated manually. Take extra care when on an
incline, as the sliding door may open or close abruptly.
● On an incline, a sliding door may close by itself after it opens automati-
cally. Make sure the sliding door is fully open and secure.
● In the following situations, the power sliding door may detect an abnormal-
ity and automatic operation may be stopped. In this case, the sliding door
has to be operated manually. Take extra care when on an incline, as the
sliding door may open or close abruptly.
• When the sliding door contacts an obstacle
• When the battery voltage suddenly drops, such as when the engine
switch is turned to the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system) or the
engine is started during automatic operation
● Do not attach any accessories other than genuine Toyota parts to the
power sliding door. The power sliding door may not operate, causing itself
to malfunction, or the power sliding door may close again after it is
opened.

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)
