become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. ( P. 386)
• 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.

Battery-saving function
In order to prevent the vehicle battery from discharging, if the headlights
and/or tail lights are on when the engine switch is turned to the “LOCK” posi-
tion (vehicles without a smart key system) or when the “ENGINE START
STOP” switch is turned off (vehicles with a smart key system) the battery
saving function will operate and automatically turn off all the lights after
approximately 20 minutes.
When the engine switch is turned to the “ON” position (vehicles without a
smart key system) or when the “ENGINE START STOP” switch is turned to
IGNITION ON mode (vehicles with a smart key system), the battery-saving
function will be disabled.
When any of the following are performed, the battery-saving function is can-
celed once and then reactivated. All the lights will turn off automatically 20
minutes after the battery-saving function has been reactivated:
●When the headlight switch is operated
● When a door is opened or closed
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 493)

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, observe the following before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.

■After recharging/reconnecting the battery (vehicles with a smart key
system)
●Unlocking the doors using the smart key system may not be possible
immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the engine with the “ENGINE START STOP” switch in ACCES-
SORY mode. The engine may not start with the “ENGINE START STOP”
switch turned off. However, the engine will operate normally from the sec-
ond attempt.
● The “ENGINE START STOP” switch mode is recorded by the vehicle. If
the battery is reconnected, the vehicle will return the “ENGINE START
STOP” switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the engine before disconnect the battery.
Take extra care when connecting the battery if the “ENGINE START
STOP” switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact your Toyota
dealer.
