●If the key is in close proximity to or touching a key registered to the security system (key
with a built-in transponder chip) of another vehicle
Immobilizer system
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
on-board computer.

Operation of each component
RC300h_EE(OM24740E)
■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.
While the battery-saving mode is set, the smart entry & start system cannot be used. To cancelthe function, press any of the electronic key but-
tons.

Driving
RC300h_EE(OM24740E)
■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, th is function cannot entirely prevent 12-volt
battery 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.
■Sounds and vibrations specific to a hybrid vehicle
 P. 88
■Electronic key battery depletion
 P. 141
■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.
■Conditions affecting operation
 P. 157
■Notes for the entry function
 P. 158
■If the hybrid system does not start
●Check that the shift lever is securely set in P. The hybrid system may not start if the shift lever is displaced out of P.
●The immobilizer system may not have been deactivated. ( P. 95)
Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
■Steering lock
After turning the power switch off and openin g and closing the doors, the steering wheel will be locked due to the steering lock func tion. Operating the power switch again auto- matically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, operation of the motor may be sus- pended if the hybrid system is turned on an d off repeatedly in a short period of time. In
this case, refrain from operating the power switch. After about 10 seconds, the steering lock motor will resume functioning.
“Steering Lock active” will be displayed on the
multi-information display.
Check that the shift lever is in P. Press the power switch while turning the steering wheel left and
right.
