■Before recharging
When recharging, the 12-volt battery produces hydrogen gas whic h is flam-
mable and explosive. Therefore, observe the following precautio ns before
recharging:
● If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
■ After recharging/reconnecting the 12-volt battery
● The hybrid system may not start. Follow the procedure below to initialize the
system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
● Vehicles with entry function: Unlocking the doors using the smart entry &
start system may not be possible immediately after reconnecting the 12-volt
battery. If this happens, use the wireless remote control or th e mechanical
key to lock/unlock the doors.
● Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. H owever, the
hybrid system will operate normally from the second attempt.
● The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to t he status it
was in before the 12-volt battery was disconnected. Make sure t o turn off
the power switch before disconnect the 12-volt battery. Take ex tra care
when connecting the 12-volt battery if the power switch mode pr ior to dis-
charge is unknown.
If the system will not start even after multiple attempts at al l methods above,
contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer.

Do not disconnect the negative (-) terminal on the body side. T he discon-
nected negative (-) terminal may touch the positive (+) termina l, which may
cause a short and result in death or serious injury.
NOTICE

Maintenance and care
■Cleaning the air intake vent
● Dust in the air intake vent may interfere with the cooling of the hybrid battery
(traction battery). If charging/discharging of the hybrid batte ry (traction bat-
tery) becomes limited, the distance that the vehicle can be dri ven using the
electric motor (traction motor) may be reduced and the fuel eco nomy may
be reduced. Inspect and clean the air intake vent periodically.
● Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter , contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ If “Maintenance required for Traction battery cooling parts See owner’s
manual.” is shown on the multi-information display
● If this message is shown on the multi-information display, remove the air
intake vent cover and clean the filter. ( P. 638)
● After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer displayed.
After the hybrid system is started, it may be necessary to driv e the vehicle
up to approximately 20 minutes before the warning message disap pears. If
the warning message does not disappear after driving for approp riately 20
minutes, have the vehicle inspected by any authorized Toyota re tailer or
Toyota authorized repairer, or any reliable repairer.
WARNING
■ When cleaning the air intake vent
● Before cleaning the air intake vent, make sure to turn the power switch off
to stop the hybrid system.
● Do not use water or other liquids to clean the air intake vent. If water is
applied to the hybrid battery (traction battery) or other compo nents, a mal-
function or fire may occur.
■ When removing the air intake vent cover
Do not touch the service plug located near the air intake vent. (P. 125)

NOTICE
■When cleaning the air intake vent
■ To prevent damage to the vehicle
● Do not allow water or foreign matter to enter the air intake vent when the
cover is removed.
● Carefully handle the removed filter so that it will not be damaged. If the fil-
ter is damaged, have it replaced with a new filter by any autho rized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r.
● Make sure to reinstall the filter and cover to their original positions after
cleaning.
● Do not install anything to the air intake vent other than the exclusive filter
for this vehicle or use the vehicle without the filter installe d.
■ If “Maintenance required for Traction battery cooling parts See owner’s
manual.” is shown on the multi-information display
If the vehicle is continuously driven with the warning message (indicating
that charging/discharging of the hybrid battery [traction batte ry] may
become limited) displayed, the hybrid battery (traction battery ) may mal-
function. If the warning message is displayed, clean the air in take vent
immediately.
When cleaning the air intake vent, make
sure to only use a vacuum to suck out
dust and clogs. If a compressed air blow
gun, etc., is used to blow out dust and
clogs, the dust or clogs may be pushed
into the air intake vent, which may affect
the performance of the hybrid battery
(traction battery) and cause a malfunc-
tion.

■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic .
■ When the 12-volt battery is removed or discharged
● Information stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at any authorized Toyota r etailer or
Toyota authorized repairer, or any reliable repairer.
● Some systems may require initialization. (P. 791)
■ When removing the 12-volt battery terminals
When the 12-volt battery terminals are removed, the information stored in the
ECU is cleared. Before removing the 12-volt battery terminals, contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ Charging the 12-volt battery
The electricity stored in the 12- volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the dra ining effects of
certain electrical appliances. If the vehicle is left for a lon g time, the 12-volt
battery may discharge, and the hybrid system may be unable to s tart. (The
12-volt battery recharges automat ically while the hybrid system is operating.)
