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 vehicle, resulting in death or serious injury.
● Ensure that all doors are properly closed and locked.
● Do not pull the inside handle of the doors while driving.
Be especially careful 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 children are seated in the rear
seats.
■ When opening or closing a door

Operation of each component
■Conditions affecting operation
The smart key system, wireless remote control and immobilizer s ystem use
weak radio waves. In the following situations, the communication between
the electronic key and the vehicle may be affected, preventing the smart key
system, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping: P. 699)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
noise

metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When other wireless key (that emit radio waves) is being used n earby
● When carrying the electronic key together with the following devices that

■Note for the entry function
●Even when the electronic key is within the effective range (det ection 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 unl ocked.
• The electronic key is on the instrument panel, floor, or in th e 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 w ave 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, th e doors may be
unlocked or locked by anyone.
● 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 han-
dle, such as in the rain or in a car wash when the electronic k ey is within the
effective range. (The door will automatically be locked after a pproximately
60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when t he electronic
key is near the vehicle, there is a possibility that the door m ay not be
unlocked by the entry function. (Use the wireless remote contro l to unlock
the doors.)
● Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor aga in.
● If the door handle becomes wet while the electronic key is with in the effec-
tive range, the door may lock and unlock repeatedly. In this ca se, follow the
following correction procedures to wash the vehicle.
• Place the electronic key in a location 6 ft. (2 m) or more awa y from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set electronic key to battery-saving mode to disable the smart key sys-
tem. ( P. 292)
● If the electronic key is inside the vehicle and a door handle b ecomes wet
during a car wash, a message may be shown on the multi-informat ion dis-
play and a buzzer will sound outside the vehicle. To turn off t he alarm, lock
all the doors.
● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
● 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 origi-
nal position and check that the doors unlock before pulling the door handle
again.
● If there is another electronic key in the detection area, it ma y take slightly
longer to unlock the doors after the door handle is gripped.
