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.
■Front side windows with UV protective
coating (vehicles with UV protective
coating)
The front side windows have UV protective
coating. To prevent any damage to the UV
protective coating, observe the following:
●If the windows are dirty, gently wipe them with a cloth soaked in water or lukewarm
water as soon as possible.
●If the windows are very dirty, do not open
and close them repeatedly.

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 intake
vent, and in the luggage compartment.
(  P.67)
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.31)
An electrical malfunction 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.303) get
wet. Failure to do so may cause the
charger to become hot and cause
burns or could cause electric shock
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.

fuse has been replaced, a bulb may need
replacement. ( P.374)
●If the replaced fuse blows again, have the
vehicle inspected by your Lexus dealer.
■If there is an overload in a circuit
The fuses are designed to blow, protecting
the wiring harness from damage.
