WARNING
■To prevent an accident
Observe the following precautions while driving the vehicle.
Failure to do so may result in a door
opening and an occupant could be thrown out of the v ehicle, resulting in
death or serious injury.
●Ensure that all doo rs are properly closed.
●Do not pull the in side handle of the doors while driving.
Be especially care ful for the front
doors, as the doors may be opened even if the inside lock buttons are in
locked position.
●Set the rear door child-protector
locks when childre n are seated in
the rear seats.
■When opening or closing a door
Check the surroundings of the vehicle such as whether the vehicle is on an
incline, whether there is enough
space for a door to open and whether a strong wind is blowing. When open -
ing or closing the door, hold the door
handle tightly to prepare for any unpredictable movement.

2264-2. Opening, closing and locking the doors
• 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 lo cked or unlocked.
• The electronic key is on the instru- ment panel, luggage co ver or floor, or
in the door pockets or glove box when
the hybrid system is started or power 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 m ay 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 unlocke d by anyone. How- ever, only the door s detecting the
electronic key can be used to lock or
unlock the vehicle.
●Even if the electronic key is not inside
the vehicle, it may be possible to start the hybrid system if the electronic key
is near the window.
●The doors may unlock if a large
amount of water splashes on the door
handle, such as in t he rain or in a car wash when the electronic key is within
the effective range . (The doors will
automatically be locked after approxi - mately 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 vehi cle, 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.)
●Touching the door lock sensor while
wearing gloves may delay or prevent lock operation. Remove the gloves
and touch the lo ck sensor again.
●When the lock operation is performed
using the lock sens or, recognition sig-
nals will be shown up to two consecu -
tive times. After this, no recognition
signals will be given.
●If the door handle becomes wet while
the electronic key is within the effec - tive range, the door may lock and
unlock repeatedly. In that case, follow
the following correction procedures to wash the vehicle:
• Place the electronic key in a location 2
m (6 ft.) or more away from the vehi - cle. (Take care to ensure that the key
is not stolen.)
• Set the electronic key to battery-sav - ing mode to disable the smart entry &
start system. ( →P.225)
●If the electronic key is inside the vehi-
cle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis -
play and a buzzer will sound outside
the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor m ay not work prop- erly if it comes int o contact with ice,
snow, mud, etc. Clean the lock sensor
and attempt to operate it again, or use the lock sensor on the lower part of
the door handle.
●A sudden approach to the effective
range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the
original position and check that the
doors unlock before pulling the door handle again.
●If there is another electronic key in the detection area, it may take slightly lon -
ger to unlock the doors after the door
handle is gripped.
■When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not
leave the electronic key within 2 m (6 ft.) of the vehicle.
●The smart entry & start system can be deactivated in advance. ( →P.633)
●Battery-saving mode can reduce the power consumption of electronic keys.
