Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (vehicles with
front and rear tires of the same size)
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden braking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use LTA (Lane Tracing Assist)
system.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.

Maintenance and care
ately after use.
●To protect the paint from damage, make
sure to observe the following precau-
tions.
• Do not use acidic, al kaline or abrasive
detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driving or park-
ing in hot weather
■Wheels and wheel ornaments (vehicles
with matte black painted wheels)
As matte black painted wheels require dif-
ferent cleaning methods than conventional
aluminum wheels, be su re to observer the
following. For details, consult your Lexus
dealer.
●Remove dirt using water. If the wheels are
excessively dirty, use a sponge or soft
cloth dampened with a diluted neutral
detergent to remove the dirt.
●When using detergent, make sure to
rinse it off with water immediately. Then
use a soft cloth to wipe off the water.
●To prevent the matte black paint from
being damaged, make sure to observe
the following precautions:
• Do not scrub or polish the wheels using a brush or dry cloth.
• Do not use any wheel coatings or abra-sive detergents.
• When using an automatic car wash,
dis-able/do not select the wheel brush
func-tion(if such an option is available).
• Do not use a high pressure pressure
washer or steam cleaner.
• Do not use detergent on the wheels when they are hot, such as after driving or
park-ing in hot weather.
■Brake pads and calipers
Rust may form if the vehicle is parked with
wet brake pads or disc rotors, causing them
to stick. Before parking the vehicle after it is
washed, drive slowly and apply the brakes
several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent
coating (if equipped)
●The following precautions can extend the
effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate
on the windows for a long period.
Clean the windows with a soft, damp
cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance
has become insufficient, the coating can
be repaired. Contact your Lexus dealer.
■Plated portions
If dirt cannot be removed, clean the parts as
follows:
●Use a soft cloth dampened with an
approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to
remove any remaining moisture.
●To remove oily deposits, use alcohol wet
wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of the
engine compartment. Doing so may
cause the electrical components, etc. to
catch fire.

2726-1. Maintenance and care
WARNING
■When cleaning the windshield (vehi-
cles with rain-sensing windshield wip-
ers)
Set the wipers to the intermittent wind-
shield wipers. ( P.150)
If AUTO mode is se lected, the wipers
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries
and cause damage to the wiper blades.
●When the upper part of the windshield
where the raindrop sensor is located is
touched by hand
●When a wet rag or si milar is held close
to the raindrop sensor
●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into
the raindrop sensor
■Precautions regarding the exhaust
pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes
and rear bumper diffusers to become
quite hot.
When washing the vehicle, be careful not
to touch the pipes and diffusers until they
have cooled sufficiently, as touching hot
exhaust pipes and rear bumper diffusers
can cause burns.
■Precaution regarding the rear
bumper
If the paint of the rear bumper is chipped
or scratched, the following systems may
not function correctly. If this occurs, con-
sult your Lexus dealer.
●Lexus Safety System + 2.5
●BSM
●RCTA
●PKSB (if equipped)
NOTICE
■To prevent paint deterioration and
corrosion on the body and compo-
nents (aluminum wheels, etc.)
●Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the
paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chipped or scratched,
have it repaired immediately.
●To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights.
●Do not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses.

2766-1. Maintenance and care
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.
It is recommended that regular mainte-
nance should be performed for areas
that are frequently touched to maintain
quality.
■Routine maintenance
This maintenance is most effective if
performed regularly (around once per
month).
1 Soak a cloth in lukewarm water
(approximately 104°F [40°C]),
wring it out thoroughly and then
wipe the entire body.
Wipe carefully so that the pile is not dishev-
eled. Be sure to prepare a clean cloth.
Once you have wiped the part with the
cloth, rinse it until it is completely clean
before using the cloth again.
2 Once it has dried, use a lint brush
or the like to comb the pile.
■When cleaning the artificial
leather (Ultrasuede
®)
 If liquid is spilled onto the surface, apply tissue paper or the like to
absorb the liquid.
 If any substance such as mud or cof-
fee dries and becomes stuck to the
surface, use a lint brush or the like to
lightly brush the dirty area and
remove the substance. Then, it is
recommended to clean the dried
substance from the surface using a
vacuum cleaner.
 For oil-based substances, use a dry
cloth or tissue paper to wipe off the
substance as much as possible,
while being careful not to spread it.
If the substance still cannot be
removed, use the following procedure
to remove it.
1 Liquid substances: Soak a cloth in
lukewarm water (approximately
104°F [40°C]), wring it out thor-
oughly and then wipe the dirty area
from the outside inward.
Wipe carefully so that the pile is not dishev-
eled. Be sure to prepare a clean cloth and
use the clean portion of it to clean the sur-
face.
Oil-based substances: Dab a cloth soaked
in benzene, lukewarm water or pure ethyl
alcohol (for drinking) within the dirty area
from the outside inward, and then dab a
dry cloth on the dirty area to absorb the
substance.
2 If the pile on the surface is dishev-
eled, use a lint brush or the like to
lightly brush the surface, and then
allow the surface to dry completely.
