■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. U se 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 obt ained 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 cut s.
■ Cleaning the air intake vents and filters
●Dust on the air intake vents or filters may interferes cooling of the hybrid bat-
tery (traction battery) and results in poor electricity and fue l consumption.
Clean the air intake vents and filters periodically.
● If continuing to drive the vehicle with “Maintenance required f or Traction bat-
tery cooling parts See owner’s manual” shown on the multi-infor mation dis-
play, the hybrid battery (traction battery) may overheat, leadi ng to
decreasing in distance that can be driven using the electric mo tor. It may
cause poor electricity and fuel consumption or a malfunction. If the warning
message is shown, clean the air intake vents and filters immediately.
● Improper handling may result in damage to the grille or filters. If you have
any concerns about cleaning the filters, contact your Toyota dealer.
● If the warning message on the multi-information display does not disappear
after cleaning the filters, have the vehicle inspected by your Toyota dealer.
