Maintenance and care
HS250h_U_75033U(Canada)
■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 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 bat-
tery (traction battery) air vents, and in the trunk.
Doing so may cause the hybrid 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 0 6 )
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, 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.

■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (→P. 4 6 9 )
●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 before the entire wiring harness is damaged.
CAUTION
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than indicated, 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.
This can cause extensive damage or even fire.
●Do not modify the fuses or fuse boxes.
■Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring near
the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer as soon as possible.
