Cleaning and protecting the vehicle interior
The following procedures will help protect your vehicle’s interior and
keep it in top condition:
■Protecting the vehicle interior
Remove dirt and dust using a vacuum cleaner. Wipe dirty sur-
faces with a cloth dampened with lukewarm water.
■Cleaning the leather areas
●Remove dirt and dust using a vacuum cleaner.
●Wipe off any excess dirt and dust with a soft cloth dampened
with diluted detergent.
Use a diluted water solution of approximately 5% neutral wool deter-
gent.
●Wring out any excess water from the cloth and thoroughly
wipe off all remaining traces of detergent.
●Wipe the surface with a dry, soft cloth to remove any remain-
ing moisture. Allow the leather to dry in a shaded and venti-
lated area.

Maintenance and care
■Caring for leather areas

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
keeping 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.
CAUTION
■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 (traction battery), electrical compo-
nents, etc. to malfunction or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(→P. 1 8 6 )
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.

stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■Water on the floor

into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.
■Cleaning the inside of the rear window

damage to the rear window defogger heater wires. Use a cloth dampened
with lukewarm water to gently wipe the window clean. Wipe the window in

Maintenance requirements
■Repair and replacement
It is recommended that genuine Toyota parts be used for repairs to ensure
performance of each system. If non-Toyota parts are used in replacement or
if a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
To e n s u r e s a f e a n d e c o n o m i c a l d r i ving, day-to-day care and regular
maintenance are essential. It is the owner’s responsibility to perform
regular checks. Toyota recommends performing the following main-
tenance:
■General maintenance
General maintenance should be performed on a daily basis.
This can be done by yourself or by a Toyota dealer.
■Scheduled maintenance
Scheduled maintenance should be performed at specified inter-
vals according to the maintenance schedule.
For details about maintenance items and schedules, refer to the
“Scheduled Maintenance Guide” or “Owner’s Manual Supplement”.
■Do-it-yourself maintenance
Yo u c a n p e r f o r m s o m e m a i n t e n a n c e p r o c e d u r e s b y y o u r s e l f .
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Toyota repair manuals is recommended.
For details about warranty coverage, refer to the separate “Owner’s
Warranty Information Booklet” or “Owner’s Manual Supplement”.
