6-1.Maintenance and care
Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle to remove any dirt and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use car
wash soap and rinse thoroughly with
water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■Black stainless steel window moldings
(IS500)
The stainless steel window moldings are
made of black oxide coated stainless steel.
When cleaning the vehicle, do not scrub the
moldings with an abrasive cleaner as their
finish may be damaged or the color may
change.
■Self-restoring coat
The vehicle body has a self-restoring coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
●The restoration time differs depending on
the depth of the scratch and outside tem-
perature.
The restoration time may become
shorter when the coating is warmed by
applying warm water.
●Deep scratches caused by keys, coins,
etc. cannot be restored.
●Do not use wax that contains abrasives.
■Automatic car washes
●Fold the mirrors before washing the vehi-
cle. Start washing from the front of the
vehicle. Make sure to extend the mirrors
before driving.
●Brushes used in automatic car washes
may scratch the vehicle surface, parts
(wheel, etc.) and damage the paint.
■High pressure car washes
As water may enter the cabin, do not bring
the nozzle tip near the gaps around the
doors or perimeter of the windows, or spray
these areas continuously.
■When using a car wash
If the door handle becomes wet while the
electronic key is within the effective range,
the door may lock and unlock repeatedly. In
that case, follow the following correction
procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or
more separate from the vehicle while the
vehicle is being washed. (Take care to
ensure that the key is not stolen.)
●Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.98)
■Wheels and wheel ornaments (vehicles
without matte black painted wheels)
●Remove any dirt immediately by using a
neutral detergent.
●Wash detergent off with water immedi-
Cleaning and protecting the
vehicle exterior

3006-3. Do-it-yourself maintenance
communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
●When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines rap-
idly for example when a tire has burst, the
warning may not function.
■Warning performance of the tire pres-
sure warning system
The warning of the tire pressure warning
system will change in accordance with driv-
ing conditions. For this reason, the system
may give a warning even if the tire pressure
does not reach a low enough level, or if the
pressure is higher th an the pressure that
was adjusted to when the system was initial-
ized.
When replacing the tires or wheels, the
tire pressure warning valve and trans-
mitters must be installed to the wheels
which will be installed to the vehicle.
When new tire pressure warning
valves and transmitte rs are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. ( P.302)
■Replacing tires and wheels
If the ID code of the tire pressure warning
valve and transmitter is not registered, the
tire pressure warning system will not work
properly. After driving for about 20 min-
utes, the tire pressure warning light blinks
for 1 minute and stays on to indicate a sys-
tem malfunction.
■The tire pressure warning system
must be initialized in the following
circumstances:
 When rotating the tires.
 When the tire inflation pressure is
changed such as when changing
traveling speed or load weight.
 When changing the tire size.
When the tire pressure warning system
is initialized, the current tire inflation

NOTICE
■Repairing or replac ing tires, wheels,
tire pressure warning valves, trans-
mitters and tire valve caps
●When removing or fitting the wheels,
tires or the tire pressure warning
valves and transmitters, contact your
Lexus dealer as the tire pressure warn-
ing valves and transmitters may be
damaged if not handled correctly.
●Make sure to install the tire valve caps.
If a tire valve cap is not installed, water
may enter the valve and cause it to
corrode, possibly leading to the valve
sticking or air to leak from the tire.
●When replacing tire valve caps, do not
use tire valve caps other than those
specified. The cap may become stuck.
■To avoid damage to the tire pressure
warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressure warning valve and
transmitter may not operate properly. If a
liquid sealant is used , contact your Lexus
dealer or other qualified service shop as
soon as possible. Afte r use of liquid seal-
ant, make sure to re place the tire pres-
sure warning valve and transmitter when
repairing or replacing the tire.
