■
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)

windshield, obstructing the driver's view and leading to an accident, resulting in
death or serious injury.

OBD (On Board Diagnostics) checks. The OBD system monitors the oper-
ation of the emission control system.
■ If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere in
the emission control system. Your vehicle may not pa ss the I/M test
and may need to be repaired. Cont act your Lexus dealer to service
the vehicle.
■ Your vehicle may not pass the I/M test in the following situations:
● When the 12-volt battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a temporary
malfunction and your vehicle may not pass the I/M test.
■ When the malfunction indicator la mp still remains on after several
driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your Lexus dealer to prep are the vehicle for re-testing.
