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.
QSelf-restoring coat
The vehicle body has a self-restoring coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
OThe coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
OThe 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.
ODeep scratches caused by keys, coins,
etc. cannot be restored.
ODo not use wax that contain abrasives.
QAutomatic car washes
OBefore washing the vehicle:
• Fold the mirrors
• Turn off the power trunk lid (if equipped)
Start washing from the front of the vehicle.
Make sure to extend the mirrors before
driving.
OBrushes used in automatic car washes
may scratch the vehicle surface, parts
(wheel, etc.) and harm your vehicle’s
paint.
ORear spoiler may not be washable in
some automatic car washes. There may
also be an increased risk of damage to
vehicle.

Maintenance and care
tors are showing on a tire.
QWhen to replace your vehicle’s tires
OTires should be replaced if:
• The treadwear indicators are showing on
a tire.
• You have tire damage such as cuts, splits, cracks deep enough to expose the fabric,
and bulges indicating internal damage
• A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult your Lexus
dealer.
OVehicles with 17-inch tires:
The wheel angle differs from vehicles
equipped with 18-inch/19-inch tires. There-
fore, 18-inch/19-inch tires cannot be
installed, as sufficient gaps with surrounding
parts cannot be ensured.
QTire life
Any tire over 6 years old must be checked
by a qualified technician even if it has sel-
dom or never been used or damage is not
obvious.
QLow profile tires (18-inch/19-inch tires)
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to use
snow tires on snowy and/or icy roads and
drive carefully at a speed appropriate for
road and weather conditions.
QMaximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR) of
either the front axle or the rear axle, which-
ever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the
load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the
tire. ( P.412)
QTire types
OSummer tires
Summer tires are high-speed perfor-
mance tires best suited to highway driv-
ing under dry conditions. Since summer
tires do not have the same traction per-
formance as snow tires, summer tires are
inadequate for driving on snow-covered
or icy roads. For driving on snow-cov-
ered roads or icy roads, the use of snow
tires is recommended. When installing
snow tires, be sure to replace all four
tires.
OAll season tires
All season tires are designed to provide
better traction in snow and to be ade-
quate for driving in most winter condi-
tions as well as for use year-round. All
season tires, howeve r, do not have ade-
quate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
OSnow tires
For driving on snow-covered roads or icy
roads, we recommend us ing snow tires. If
you need snow tires, select tires of the
same size, construction and load capacity
as the originally installed tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also
have radial construction. Do not install
studded tires without first checking local
regulations for possible restrictions.
Snow tires should be installed on all
wheels. ( P.260)
QIf the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.

3326-3. Do-it-yourself maintenance
Rotate the tires in the order shown.
To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Do not fail to initialize the tire pressure
warning system after tire rotation.
QWhen rotating the tires
Make sure that the power switch is off. If the
tires are rotated while the power switch is in
ON mode, the tire position information will
not be updated.
If this accidentally occurs, either turn the
power switch to off and then to ON mode,
or initialize the system after checking that
the tire pressure is properly adjusted.
WARNING
QWhen inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drivetrain as well as danger-
ous handling characteristics, which may
lead to an accident re sulting in death or
serious injury.
ODo not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
ODo not use tire sizes other than those
recommended by Lexus.
ODo not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
ODo not tow if your vehicle has a com-
pact spare tire installed.
ODo not mix summer, all season and
snow tires.
ODo not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
NOTICE
QDriving on rough roads
Take particular car e when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
QLow profile tires (18-inch/19-inch
tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
OBe sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
OAvoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
QIf tire inflation pressure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
