Caring for leather areas
Lexus recommends cleaning the interior of
the vehicle at least twice a year to maintain
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.
Brush the surfaces using a soft
brush.
Do not brush hard as doing so may cause
damage.
Wipe the surfaces clean with a soft
cloth that has been dampened in
cold or lukewarm water and
squeezed out.
Allow the artificial leather (Alcan-
tara
®*
) to dry in a shaded and venti-
lated area.

Repair and replacement
It is recommended that genuine Lexus parts
be used for repairs to ensure performance
of each system. If non-Lexus parts are used
in replacement or if a repair shop other than
a Lexus dealer performs repairs, confirm
the warranty coverage.
■
Allow inspection and repairs to be per-
formed by a Lexus dealer
●
Lexus technicians are well-trained spe-
cialists and are kept up to date with the
latest service information. They are well
informed about the operations of all sys-
tems on your vehicle.
●
Keep a copy of the repair order. It proves
that the maintenance that has been per-
formed is under warranty coverage. If any
problem should arise while your vehicle is
under warranty, your Lexus dealer will
promptly take care of it.
General maintenance should be per-
formed on a daily basis. This can be
done by yourself or by a Lexus dealer.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.
For details about maintenance items and
schedules, refer to the “Warranty and Ser-
vice Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

U.S.A.:
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. (Minimum temperature: -31°F [-

For more details about engine coolant, con-
tact your Lexus dealer.
■
If the coolant level drops within a short
time of replenishing
Visually check the radiator, hoses,
engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have your Lexus
dealer test the cap and check for leaks in
the cooling system.
Check the radiator and condenser and
clear away any foreign objects.
If either of the above parts is extremely
dirty or you are not sure of their condi-
tion, have your vehicle inspected by
your Lexus dealer.
■
Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank.
WARNING
■
When the engine <hybrid system> is
hot
LC500: Do not remove the engine cool-
ant reservoir cap or the coolant inlet cap.
(
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
LC500h: Do not remove the

is removed, causing serious injuries, such
as burns.
NOTICE
■
When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mixture
of water and antifreeze must be used to
provide proper lubrication, corrosion
protection and cooling. Be sure to read
the antifreeze or coolant label.
■
If you spill coolant
Be sure to wash it off with water to pre-
vent it from damaging parts or paint.
