■Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
■Conditions affecting operation
The smart access system with push-button st art, wireless remote control and immobilizer
system use weak radio waves. In the following situations, the communication between the
electronic key and the vehicle may be affect ed, preventing the smart access system with
push-button start, wireless remote control an d immobilizer system from operating prop-
erly. (Ways of coping: P. 692)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas st ation, radio station, large display, airport or
other facility that generates strong radio wave s or electrical noise
●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
• Portable radio, cellular phone, cordle ss phone or other wireless communication
devices
• Another vehicle’s electronic key, another electronic key of your vehicle, or a wireless
key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or me tallic objects are attached to the rear win-
dow
●When the electronic key is placed near a battery charger or electronic devices

Operation of each component
RX450h_RX450hL_U
■Note 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 near the ground or in a high place, or too close to the rear
bumper center when the back door is opened.
• The electronic key is on th e instrument panel, luggage co mpartment, 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 th e 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 outs ide 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 th e effective range, the doors may be locked or
unlocked 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 wa ter 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 door
will automatically be locked after approx imately 60 seconds if the doors are not
opened and closed.)
●If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock sensor while wearin g gloves may delay or prevent lock opera-
tion. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using the lock sensor, recognition 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 el ectronic key is within the effective 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 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 battery-saving mode to disable the smart access system with push-button start. ( P. 160)
●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 mult i-information display 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.
●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 de tection area, it may take slightly longer to
unlock the doors after the door handle is gripped.
