■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
WARNING
■ Water in the vehicle
● Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air vents, and in the rear seat. Doing so
may cause the hybrid battery, electrical components, etc. to malfunction or
catch fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 42)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, obser ve the following precautions 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.
■ When disconnecting the 12-volt battery terminals
Always disconnect the negative (-) terminal first.
■ After recharging/reconnecting the 12-volt battery
● Unlocking the doors using entry function of 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 the mechanical key to lock/
unlock the doors.
● Vehicles with a smart entry & start system: Start the hybrid system with the
power switch in ACCESSORY mode. The hybrid system may not start with
the power switch turned off. However, the hybrid system will operate nor-
mally from the second attempt.
● Vehicles with a smart entry & start system: 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 the status it was in before the 12-volt bat-
tery was disconnected. Make sure to turn off the power before disconnect
the 12-volt battery. Take extra care when connecting the 12-volt battery if
the power switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional.

WARNING
■Chemicals in the 12-volt battery
The 12-volt battery contains poisonous and corrosive sulfuric acid and may
produce hydrogen gas which is flammable and explosive. To reduce the risk
of death or serious injury, take the following precautions while working on or
near the 12-volt battery:
● Do not cause sparks by touching the 12-volt battery terminals with tools.
● Do not smoke or light a match near the 12-volt battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the 12-volt battery.
● Keep children away from 12-volt battery.
■ Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charge the 12-
volt battery in a garage or closed room where there is insufficient ventila-
tion.
■ When disconnecting the 12-volt battery terminals
Always disconnect the negative (-) terminal first. If the positive (+) terminal
is disconnected first and touches a surrounding metal surface sparks will be
produced, possibly starting a fire. It could also result in an electric shock or
serious injury.
