●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
Immobilizer system
The vehicle’s keys have built-in transponder chips that prevent
the hybrid system 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 vehi-
cle.
This system is designed to help prevent vehicle theft but does
not guarantee absolute security against all vehicle thefts.

Operation of each component
■Conditions affecting operation
The smart key system, 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 affected, preventing the smart key
system, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping: P. 484)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates 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
• Portable radio, cellular phone, cordless phone or other wireless commu-
nication devices
• Another vehicle’s electronic key, another electronic key of your vehicle, 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 metallic objects are attached to the
rear window
●When the electronic key is placed near a battery charger or electronic
devices
●When the vehicle is parked in a pay parking spot where radio waves are
emitted.

1984-2. Driving procedures
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (with the hybrid system not operating) for more than an hour with the
shift lever in P, the power switch will automatically turn off. However, this func-
tion cannot entirely prevent 12-volt battery discharge. Do not leave the vehi-
cle with the power switch in ACCESSORY or ON mode for long periods of
time when the hybrid system is not operating.
■Automatic hybrid system shut off feature
●The vehicle is equipped with a feature that automatically shuts off the hybrid
system when the shift lever is in P with the hybrid system operating for an
extended period.
●The hybrid system will automatically shut off after approximately 1 hour if it
has been left running while the shift lever is in P.
●The timer for the automatic hybrid system shut off feature will reset if the
brake pedal is depressed or if the shift lever is in a position other than P.
●After the vehicle is parked, if the door is locked with the door lock switch
(P. 140) from the inside or the mechanical key (P. 484) from the outside,
the automatic hybrid system shut off feature will be disabled. The timer for
the automatic hybrid system shut off feature will be re-enabled if the driver’s
door is opened.
■Sounds and vibrations specific to a hybrid vehicle
P. 78
■Electronic key battery depletion
P. 136
■When the ambient temperature is low, such as during winter driving con-
ditions
●When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady
on, as steady means the vehicle is able to move.
●When the hybrid battery (traction battery) is extremely cold (below approxi-
mately -22°F [-30°C]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to
the outside temperature increase etc.
■Conditions affecting operation
P. 151
■Notes for the entry function
P. 152
■If the hybrid system does not start
●The immobilizer system may not have been deactivated. (P. 86)
Contact your Toyota dealer.
●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.

4827-2. Steps to take in an emergency
One of the following may be the cause of the problem:
●The electronic key may not be functioning properly. (P. 485)
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
●There may be a malfunction in the immobilizer system.
(P. 86)
●There may be a malfunction in the steering lock system.
●The hybrid system may be malfunctioning due to an electrical prob-
lem such as electronic key battery depletion or a blown fuse. How-
ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. (P. 483)
●The temperature of the hybrid battery (traction battery) may be
extremely low (below approximately -22°F [-30°C]). (P. 81, 198)
One of the following may be the cause of the problem:
●The 12-volt battery may be discharged. (P. 487)
●The 12-volt battery terminal connections may be loose or corroded.
(P. 411)
If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on
the situation. Check the following and perform the appropriate
procedure:
The hybrid system will not start even though the correct starting
procedure is being followed. (P. 196)
The interior lights and headlights are dim, or the horn does not
sound or sounds at a low volume.
