■Remaining hybrid battery (tract ion battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or electricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may not
reach the highest level (level 8). However, this does not indicate a malfunc-
tion.
■ Resetting the consumption data (audio system)
Selecting “Clear” on the “Trip Information” screen will reset the fuel consump-
tion and the regenerated energy for the past 15 minutes. Selecting “Clear” on
the “Past Record” screen will reset the past records and best past fuel con-
sumption. Selecting “Yes” on the following screen will confirm resetting of all
the data.
■ Updating the past record data (audio system)
Selecting “Update” on the “Past Record” screen will update the past record
data.

Key battery depletion
Vehicles without a smart key system
If the wireless remote control function does not operate, the battery may be
depleted. Replace the battery when necessary. (→ P. 448)
Vehicles with a smart key system
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin when the hybrid
system stops. ( →P. 499)
● 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. 448)
• The smart key 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 3 ft. (1
m) 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. 448
■ Confirmation of the registered key number (vehicles with a smart key
system)
The number of keys already registered to the vehicle can be confirmed. Ask
your Toyota dealer for details.
■ If a wrong key is used (vehicles with a smart key system)
The key cylinder rotates freely to isolate inside mechanism.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. wireless remote control system) can be changed.

Notes for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is on the instrument panel, luggage cover or floor, in
the door pockets or glove box when the hybrid system is started or
“POWER” switch modes are changed.
● Do not exit the vehicle with the electronic key placed on the instrument
panel or near the door pockets. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door
will become lockable from the outside, possibly trapping the electronic key
inside the vehicle.
● As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Whether or not the electronic key is inside the vehicle, the hybrid system
could be started if the electronic key is near the window.
● The doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
60 seconds if the doors are not opened and closed.)
● The lock and unlock sensors may not work properly if they come into con-
tact with ice, snow, mud, etc. Clean the sensors and attempt to operate
them again.
● If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Using the wireless remote control to unlock
the doors may resume the function.)
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart key system. ( →P. 141)
