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.
■When cleaning the carpeted portions of
the glove box, console box, etc.
If a strong adhesive tape is used, there is a
possibility that the surface of the carpet
could be damaged.
Cleaning and protecting the
vehicle interior
Perform cleaning in a manner
appropriate to each component
and its material.
Protecting the vehicle interior
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 vents, and
in the trunk. ( P.69)
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.29)
An electrical malfunction may cause
the airbags to deploy or not function
properly, 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, obstructin g the driver’s view
and leading to an accident, resulting in
death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types of
detergent, as they may discolor the
vehicle interior or cause streaks or
damage to painted surfaces:
• Areas other than the seats and steer- ing wheel: Organic substances such as
benzene or gasoline, alkaline or acidic
solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
• Steering wheel: Organic substances, such as thinner, and cleaner that con-
tains alcohol
●Do not use polish wax or polish

regularly. If dirty areas are left uncleaned for
long periods of time, they may be difficult to
clean.
 Remove dirt and dust using a vac-
uum cleaner.
 Wipe off any excess dirt and dust

the quality of the vehicle’s interior.
 Remove dirt and dust using a vac-
uum cleaner.
 Wipe it off with a soft cloth damp-
ened with neutral detergent diluted
to approximately 1%.
 Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent and
water.

LS500h_OM_(U)_1809

Vehicle specifications
■Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction.
■Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudd
en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is properly inflated and not
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
Glossary of tire terminology
Tire related termMeaning
Cold tire inflation pressure
Tire pressure when the vehicle has been parked for
three hours or more, or has not been driven more
than 1 mile or 1.5 km under that condition
Maximum inflation pressureThe maximum cold inflated pressure to which a tire
may be inflated, shown on the sidewall of the tire
Recommended inflation pressureCold tire inflation pressure recommended by a
manufacturer
Accessory weight
The combined weight (in excess of those standard
items which may be replaced) of hybrid transmis-
sion, power steering, power brakes, power win-
dows, power seats, radio and heater, to the extent
that these items are available as factory-installed
equipment (whether installed or not)
