GS450h_OM_OM30E99U_(U)
Immobilizer system
The indicator light flashes after the
power switch has been turned off to
indicate that the system is operating.
The indicator light stops flashing after
the power switch has been turned to
ACCESSORY or ON mode to indi-
cate that the system has been canceled.
■System maintenance
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 transponder chips that prevent the hybrid sys-
tem from starting if a key has not been previously registered in the vehicle’s
on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not guarantee
absolute security against all vehicle thefts.

Operation of each component
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the following
situations, the communication between th e electronic key and the vehicle may be
affected, preventing the smart access system with push-button start, wireless remote
control and immobilizer system from operating properly. (Ways of coping: P. 4 5 1 )
●When the electronic key battery is depleted
●Near a TV tower, electric powe r plant, gas station, radio station, large display, airport or
other facility that generates strong radio waves or electrical noise
●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 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.

4-2. Driving procedures
If the hybrid system is stopped with the shift lever in a position other than P, the
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.
Check that “Turn Off Vehicle” on the multi-information display is off.
■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-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. 6 8
■Electronic key battery depletion
P. 118
■When the ambient temperature is low, such as during winter driving conditions
When starting the hybrid system, the flas hing 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.

■Notes for the entry function
P. 1 3 6
■If the hybrid system does not start
●The immobilizer system may no t have been deactivated. (P. 74 )

lever is displaced out of P. “Shift to P position to Start” will be displayed on the multi-
information display.
■Steering lock
After turning the power switch off and opening and closing the doors, the steering wheel
will be locked due to the stee ring lock function. Operating the power switch again auto-
matically cancels the steering lock.
