Maintenance and care
■When using a car wash (vehicles with a smart entry & start system)
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In that case, follow the fol-
lowing correction procedures to wash the vehicle:
● Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not
stolen.)
● Set the electronic key to battery-saving mode to disable the smart entry &
start system. ( P. 136)
■ Aluminum wheels
● Remove any dirt immediately by using a neutral detergent.
● Wash detergent off with water immediately after use.
● To protect the paint from damage, make sure to observe the following pre-
cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
■ Bumpers
Do not scrub with abrasive cleaners.
WARNING
■ When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.

Maintenance and care
■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 luggage compartment.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 39)
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, 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
● Vehicles with a smart entry & start system: Unlocking the doors using the
entry function may not be possible immediately after reconnecting the 12-
volt battery. If this happens, use the wireless remote control or the mechani-
cal 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. However, 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 the status it
was in before the 12-volt battery was disconnected. Make sure to turn the
power switch off before disconnecting the 12-volt battery. Take extra care
when connecting the 12-volt battery if the power switch mode prior to dis-
charge is unknown.
● When the 12-volt battery is reconnected, start the hybrid system, depress
the brake pedal, and confirm that it is possible to shift into each shift posi-
tion.
If the system will not start even after multiple attempts, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
