4-1. Maintenance and care
nCaring 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.
nShampooing 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 apply water. Excellent
results are obtained by keeping the carpet as dry as possible.
nSeat 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
nWater in the vehicle
lDo not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch fire.
lDo not get any of the SRS components or wiring in the vehicle interior wet.
(→P. 111)
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or severe injury.
nCleaning 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.

4-3. Do-it-yourself maintenance
nAfter a fuse is replaced
lIf the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (→P. 511)
lIf the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.
nIf there is an overload in the circuit
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION
nTo prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
lNever use a fuse of a higher amperage rating than indicated, or use any other
object in place of a fuse.
lAlways 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.
lDo not modify fuse or fuse boxes.
NOTICE
nBefore replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer.
