Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situ-
ations, the communication between the electronic key and the vehicle may be
affected, preventing the smart entry & start system, wireless remote control
and immobilizer system from operating properly. (Ways of coping: P. 908)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
When the electronic key is in contact with, or is covered by the following
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 keys (that emit radio waves) are being used nearby
When carrying the electronic key together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
If window tint with a metallic content or metallic objects are attached to the
rear window

Operation of each component

Note for the entry 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 rear bumper center when the trunk is opened.
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. 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 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 possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)

1523-2. Opening, closing and locking the doors and trunk
GS450h_300h_OM_OM30D53E_(EE)
Note for locking the doors (vehicles with entry function)
Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
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
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry
& start system. (P. 149)
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 dis-
play and a buzzer will sound outside the vehicle. To turn off the 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, or use
the lock sensor on the lower part of the door handle.
Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.
Note for the unlocking function (vehicles with entry function)
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.
Gripping the door handle when wearing a glove may not unlock the door.
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
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry
& start system. (P. 149)
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.
Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.

Operation of each component
GS450h_300h_OM_OM30D53E_(EE)
Note for the push-start function
Even when the electronic key is within the effective range (detection areas),
the system may not operate properly when the electronic key is on the
instrument panel, rear package tray or floor, or in the door pockets or glove
box when the hybrid system is started or power switch modes are changed.
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.
When the vehicle is not driven for extended periods
Vehicles with entry function: 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. 942)
Alarm (if equipped)
Using the smart entry & start system to lock the doors will set the alarm sys-
tem.
(P. 97)
To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention function
may not operate.)
Do not leave the electronic key inside the luggage compartment.
The key confinement prevention function may not operate, depending on
the location of the key (close to a spare tire [if equipped], the inside edge of
the luggage compartment), conditions (inside a metal bag, close to metallic
objects) and the radio waves in the surrounding area. (P. 189)
If the smart entry & start system does not operate properly
Locking and unlocking the doors and opening the trunk: Use the mechani-
cal key.
(P. 908)
Starting the hybrid system: P. 9 0 9

Electronic key battery depletion
The standard battery life is 1 to 2 years. (The card key battery life is about a
year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 867)
As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms
indicate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 777)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Table lamps
• Induction cookers
When the electronic key battery is fully depleted
P. 7 7 7
Customization
Settings (e. g. smart entry & start system) can be changed.
(Customizable features: P. 942)
If the smart entry & start system has been deactivated in a customized setting
Locking and unlocking the doors and opening the trunk:
Use the wireless remote control or mechanical key. (P. 168, 908)
Starting the hybrid system and changing power switch modes:P. 9 0 9
Stopping the hybrid system: P. 2 4 7
