861-2. Hybrid system
PRIUS +_OM_OM47888E_(EE)
There is an air intake vent under
the right-hand front seat for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vent
becomes blocked, the hybrid bat-
tery (traction battery) may over-
heat, leading to a reduction in
hybrid battery (traction battery)
output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off system activates, your vehicle will not restart.
To restart the hybrid system, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. (→P. 388)

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. 206, 247)
● The vehicle speed is approximately 130 km/h (80 mph) or below.
Eco Driving Indicator Light can be set to activated or deactivated. ( →P. 115)

PRIUS +_OM_OM47888E_(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 a message
will be displayed on the multi-information display (if equipped) when the
hybrid system stops. ( →P. 403)
● 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. 351)
• 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
• Recharging cellular phones or cordless phones
• Induction cookers
• Table lamps
■ Replacing the battery
→ P. 351
■ If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.
