Maintenance and care
Remove dirt and dust using a vac-
uum cleaner. Wipe dirty surfaces
with a cloth dampened with luke-
warm water.
If dirt cannot be removed, wipe it off
with a soft cloth dampened with
neutral detergent diluted to approx-
imately 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 foaming-type
cleaners available. Use a sponge or brush
to apply the foam. Rub in overlapping cir-
cles. 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 spon ge. Also check the
belts periodically for excessive wear, fraying
or cuts.
■When cleaning the carpeted portions of
the glove box, console box, etc.
If a strong adhesive tape is used, there is a
possibility that the surface of the carpet
could be damaged.
Cleaning and protecting the
vehicle interior
Perform cleaning in a manner
appropriate to each component
and its material.

WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehi-
cle, such as on the floor, in the hybrid
battery (traction battery) air vents, and
in the trunk. ( P.69)
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.29)
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, obstructin g the driver’s view
and leading to an accident, resulting in
death or serious injury.

detergent, as they may discolor the
vehicle interior or cause streaks or
damage to painted surfaces:
• Areas other than the seats and steer- ing wheel: Organic substances such as
benzene or gasoline, alkaline or acidic
solutions, dye, and bleach

• Steering wheel: Organic substances, such as thinner, and cleaner that con-
tains alcohol
