1-1. Hybrid system
1
Before driving
■
Charging the hybrid battery (traction battery)
●As the gasoline engine charges the hybrid battery (traction battery), the
battery does not need to be charged from an outside source. However, if
the vehicle is left parked for a long time the hybrid battery will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every
few months for at least 30 minutes or 10 miles (16 km). If the hybrid bat-
tery becomes fully discharged and you are unable to jump-start the vehi-
cle with the 12-volt battery, contact your Toyota dealer.
● If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. Always put the shift lever in P when the vehicle is stopped.
When driving in heavy traffic, operate the vehicle with the shift lever in D
or B to avoid discharging the battery.
■ Charging the 12-volt battery
P. 477
■ After the 12-volt battery has di scharged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact your Toyota
dealer.

Before driving
■
Switching the door unlock function
It is possible to set which doors the entry function unlocks using the wireless
remote control.
Turn the “POWER” switch off.
When the indicator light on the key surface is not on, press and
hold or for about 5 seconds while pressing and holding
.
The setting changes each time an operation is performed, as shown below.
(When changing the setting continuously, release the buttons, wait for at
least 5 seconds, and repeat step 2.)
■ Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic 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 key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m)
of the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
● If the smart key system has not been used for 14 days or longer, the
doors cannot be unlocked at any of the doors except the driver’s door. In
this case, take hold of the driver’s door handle, or use the wireless
remote control or the mechanical key, to unlock the doors.

When stopping the hybrid system with the shift lever in a
position other than P
If the hybrid system is stopped with the shift lever in a position other
than P, the “POWER” switch will not be turned off but instead be
turned to ACCESSORY mode. Perform the following procedure to
turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that is displayed on the multi-information dis-
play and then press the “POWER” switch once.
Check that on the multi- information display is off.
■Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON mode
with the hybrid system not operating for more than 20 minutes (ACCES-
SORY mode) or one hour (ON mode), the “POWER” switch will automati-
cally turn off. However, this function cannot entirely prevent 12-volt battery
discharge. Do not leave the vehicle with the “POWER” switch in ACCES-
SORY or ON mode for long periods of time when the hybrid system is not
operating.

■The clock is displayed when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The “POWER” switch is in ON mode.
■ Eco score
●As the accelerator pedal is not depressed, the driven distance using
cruise control (if equipped) is not included in the eco score.
● As the eco score evaluation differs according to driving conditions and
environmental factors, in some cases it may not be linked to fuel con-
sumption.
■ Eco savings
●Fuel cost and savings should be used as a guide only.
● Depending on refueling methods, driving conditions and environmental
factors, the actual and displayed fuel costs may differ.
● In some cases, fuel cost and savings may not be linked to the eco score
evaluation.
■ When disconnecting and reconnect ing 12-volt battery terminals
The following information data will be reset:
● Clock
● Past record (aside from the top 3 results)
● Average fuel consumption
● Cruising range
● Average vehicle speed
● Driving time
● EV driving rate/EV driven distance
Additionally, some displays may return to their default settings.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.
