WARNING
●Do not allow a child to open or
close the back door.
Doing so may cause the back
door to move unexpectedly, or
cause the child’s hands, head,
or neck to be caught by the
closing back door.
■Operating the back door
●Remove any heavy loads, such
as snow and ice, from the back
door before opening it. Failure
to do so may cause the back
door to suddenly shut again
after it is opened.
●When opening or closing the
back door, thoroughly check to
make sure the surrounding area
is safe.
●If anyone is in the vicinity, make
sure they are safe and let them
know that the back door is
about to open or close.
●Use caution when opening or
closing the back door in windy
weather as it may move
abruptly in strong wind.
●The back door may suddenly
shut if it is not opened fully. It is
more difficult to open or close
the back door on an incline than
on a level surface, so beware of
the back door unexpectedly
opening or closing by itself.
Make sure that the back door is
fully open and secure before
using the luggage compartment.
●When closing the back door,
take extra care to prevent your
fingers etc. from being caught.
●When closing the back door,
make sure to press it lightly on
its outer surface. If the back
door handle is used to fully
close the back door, it may
result in hands or arms being
caught.
●Do not pull on the back door
damper stay to close the back
door, and do not hang on the
back door damper stay. Doing
so may cause hands to be
caught or the back door damper
stay to break, causing an acci-
dent.
●If a bicycle carrier or similar
heavy object is attached to the
back door, it may suddenly shut
again after being opened, caus-
ing someone’s hands, head or
neck to be caught and injured.
When installing an accessory
part to the back door, using a
genuine Toyota part is recom-
mended.

■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 cover 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 unl ock 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 w ithin 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 possib ility that the door
may not be unlocke d by the entry
function. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock
sensor while wearing gloves may
prevent lock or unlock operation.
●When the lock operation is per-
formed using the lock sensor, rec-
ognition 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 that
case, follow the
following correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca-
tion 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 bat- tery-saving mode to disable the
smart key system. ( P.104)
●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 vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it comes into contact
with ice, snow, m ud, etc. Clean
the lock sensor and attempt to
operate it again.
●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 befo re pulling the
door handle again.
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.
