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 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.

●By keeping the indicator within Eco area, more Eco-friendly driving can be
achieved.
● Charge area indicates regeneration
* status. Regenerated energy will be
used to charge the hybrid battery (traction battery).
*: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.
■ Eco Driving Indicator Light (vehicl es without multi-information display)
When all of the following conditions ar e satisfied and the Eco-friendly driving,
the light will illuminate:
● Driving with the shift position in D
● Either normal mode or Eco drive mode is selected, and EV drive mode or
power mode are not in use ( →P. 214, 255)
● The vehicle speed is approximately 130 km/h (80 mph) or below.
Eco Driving Indicator Light can be set to activated or deactivated. ( →P. 117)

PRIUS +_OM_OM47B24E_(EE)■
Electronic key battery depletion
●The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin, and the smart
entry & start system warning light will flash (vehicles without multi-informa-
tion display) or a message will be displayed on the multi-information display
(vehicles with multi-information display) when the hybrid system stops.
(→ P. 415)
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( →P. 361)
• The smart entry & start system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appl iances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
■ Replacing the battery
→ P. 361
■ Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask
any authorized Toyota dealer or re pairer, or another duly qualified and
equipped professional.
■ If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.

Battery-saving function
The battery-saving function will be activated in order to prevent the electronic
key battery and the 12-volt battery from being discharged while the vehicle is
not in operation for a long time.
●In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.) of
the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
● If the smart entry & start system has not been used for 14 days or longer,
the doors cannot be unlocked at any doors except the driver’s door. In this
case, take hold of the driver’s door handle, or use the wireless remote con-
trol or the mechanical key, to unlock 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.
