Maintenance and care
Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-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 keeping the carpet as
dry as possible.
■Handling the 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 and protect-
ing the vehicle interior

interior
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 lug-
gage compartment.
Doing so may cause the hybrid
battery, electrical components,
etc. to malfunction or catch fire.
●Do not get any of the SRS com-
ponents or wiring in the vehicle
interior wet.
(  P. 3 4 )
An electrical ma lfunction may
cause the airbags to deploy or
not function properly, resulting
in death or serious injury.
●Vehicles with wireless charger:
Do not let the wireless charger
(  P.373) get wet. Failure to do
so may cause t he charger to
become hot and cause burns or
could cause electric shock
resulting in death or serious
injury.
■Cleaning the interior (espe-
cially 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.

■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performanc e of each sys-

well-trained specialists and are
kept up to date with the latest ser-
vice information. They are well
informed about the operation of all

ranty coverage. If any problem
should arise while your vehicle is
under warranty, your Toyota
dealer will promptly take care of it.
General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.
For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
