■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depl etion is minimized by stopping the elec- tronic key from receiving radio waves.
■Conditions affecting operation
The smart entry & start system uses weak ra dio waves. In the following situations, the communication between the electronic key an d the vehicle may be affected, preventing the smart entry & start system, wireless remote control and immobilizer system from
operating properly. (Ways of coping: P. 578)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, airport or
other facility that gene rates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless com- munication device
●When the electronic key is in contact wi th, 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 radiowaves
• 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 me tallic objects are attached to the rear win-
dow
●When the electronic key is placed near a battery charger or electronic devices
Press twice while pressing and holding
. Confirm that the electronic key indica-
tor flashes 4 times.

■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 trunk is opened. • The electronic key is on the instrument pa nel, 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.
●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 outside the cabin and the doors 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 orunlocked by anyone. However, only the doors detecting the electronic key can be usedto unlock the vehicle.
●Even if the electronic key is not inside the ve hicle, it may be possible to start the hybrid system if the electronic key is near the window.
●The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash, when th e electronic key is within the effective range. (The doors will automatically be locked after approximately 30 seconds if the doorsare not opened and closed.)
●If the wireless remote control is used to lock the doors when the electronic key is nearthe 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 or unlock sensor while wearing gloves may prevent lock or unlock operation.
●If the door handle becomes wet while the electronic key is within the effective range,the door may lock and unlock repeatedly. In this 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 sys-
tem. ( P. 157)
●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 both side 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 handle operation or a handle oper ation immediately after entering the effec- tive range may prevent the doors from bein g unlocked. Touch the door unlock sensor
and check that the doors are unlocked before pulling the door handle again.
●Unlocking the vehicle may take more time if another electronic key is within the effec- tive range.
