The vehicle has a maintenance-free type immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key to the security system (key with a built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transpon der chips that prevent the hybrid sys-
tem from starting if a key has not been previously registered in the vehicle’s

Operation of each component
GS450h_300h_OM_OM30F92E_(EE)
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery de pletion 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 and the vehicle may be affected, preventingthe smart entry & start system, wireless re mote control and immobilizer system from
operating properly. (Ways of coping: P. 527)
●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 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
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
• 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. While the battery-saving mode is set, the smart

power switch will not be turned off but instead be turned to ACCESSORY
mode. Perform the following procedure to turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that “Turn Off Vehicle” is displayed on the multi-information display
and then press the power switch once.

■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON mode (the
hybrid system is not operating) for more than an hour with the shift lever in P, the power switch will automatically turn off. However, this function cannot entirely prevent 12-voltbattery discharge. Do not leave the vehicle with the power switch in ACCESSORY or
ON mode for long periods of time when the hybrid system is not operating.

■When the ambient temperature is low, such as during winter driving conditions
When starting the hybrid system, the flashing time of the “READY” indicator may be long. Leave the vehicle as it is until the “REA DY” indicator is steady on, as steady means the vehicle is able to move.
