wipers)
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
■ Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.

7-1. 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.
■ Cleaning the air intake vent
●If the vehicle is driven further after dust has built up and clogged the air
intake vent and filter, the hybrid battery (traction battery) will overheat,
reducing the driving range of the electric motor and worsening fuel econ-
omy. Periodically clean the air intake vent to keep dust from building up in
the air intake vent and filter.
● Improper handling may result in damage to the air intake vent cover. If you
have any concerns about cleaning the part yourself, contact your Toyota
dealer.
● The necessary cleaning interval of the air intake vent will differ according to
the vehicle usage environment.
■ If “Maintenance required for Traction battery cooling parts See owner’s
manual” is shown on the multi-information display
● If “Maintenance required for Traction battery cooling parts See owner’s
manual” is shown on the multi-information display, the air intake vent and fil-
ter may be clogged due to dust build-up. Refer to the cleaning procedure
and clean the air intake vent.
● If the vehicle is driven further while “Maintenance required for Traction bat-
tery cooling parts See owner’s manual” is shown on the multi-information
display, the hybrid battery (traction battery) may overheat, reducing the driv-
ing range, worsening fuel economy and causing damage. Periodically clean
the air intake vent to keep dust from building up in the air intake vent and fil-
ter.
● If the warning message continues to be shown on the multi-information dis-
play even after cleaning the air intake vent, have the vehicle inspected by
your Toyota dealer.
