6384-1. Maintenance and care
■
Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain 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 overlappin g circles. Do not apply water. 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 vehicl e, such as on the floor and in the hybrid
battery (traction battery) air vents or in the luggage compartment.
Doing so may cause the hybr id battery, electrical components, etc. to malfunc-
tion or catch fire.●
Do not get any of the SRS components or wiring in the vehicle interior wet.
(  P. 1 3 4 )
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or severe 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.

7044-3. Do-it-yourself maintenance
■
After a fuse is replaced ●
If the lights do not turn on even afte r the fuse has been replaced, a bulb may
need replacement. (  P. 7 0 8 )●
If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.■
If there is an overload in the circuit
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION■
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or injury. ●
Never use a fuse of a higher amperage rating than that in dicated, or use any
other object in place of a fuse.●
Always use a genuine Lexus fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix. ●
Do not modify the fuses or fuse boxes.
NOTICE■
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer as soon as possible.
