For safety and security
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 indicate 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 registered 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 system from starting if a key has not been previously
registered in the vehi cle’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.

3-2. Opening, closing and locking the doors
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.
■ 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. 705)
● 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 key (that emit radio waves) is 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 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
Press twice while pressing and
holding . Confirm that the electronic
key indicator flashes 4 times.
While the battery-saving mode is set, the
smart key system cannot be used. To
cancel the function, press any of the elec-
tronic key buttons.

4-2. Driving procedures
■When the ambient temperature is low, such as during winter driving con-
ditions

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.
