Cleaning and protecting the vehicle exterior
●Working from top to bott
om, liberally apply water to the vehicle body, wheel
wells and underside of the vehicl e 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 wa sh soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Automatic car washes
●Fold the mirrors back before washing the ve hicle. 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 and harm your
vehicle’s paint.
●Rear spoiler may not be wash able in some automatic car washes. There may also be an
increased risk of damage to vehicle.
■High pressure car washes
As water may enter the cabin, do not bring th e nozzle tip near the gaps around the doors
or perimeter of the windows, or spray these areas continuously.
■Wheels (including surrounding parts)
●Remove any dirt immediately by using a neut ral detergent. Do not use hard brushes or
abrasive cleaners. Do not use strong or harsh chemical cleaners. Use the same mild
detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after driving for
long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
Perform the following to protect the ve hicle and maintain it in prime condi-
tion:

LX570_OM_OM60R61U_(U)6-1. Maintenance and care
NOTICE
■To prevent paint deterioration and corrosion
on the body and components (aluminum
wheels etc.)
●Wash the vehicle immediatel y 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 you see dead insects, insect drop pings or bird droppings on the paint
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoli ne 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 wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic subs tances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wipers may operate and the wiper blades may be
damaged.
■When using a high pressure car wash
●Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
•Brake parts
●Keep the cleaning nozzle at least 11.9 in. (30 cm) away from the vehicle body. Other-
wise resin section, such as moldings and bumpers, may be deformed and damaged.
Also, do not continuously hold the nozzle in the same place.
●Do not spray the lower part of the windshield continuously. If water enters the air con-
ditioning system intake located near the lo wer part of the windshield, the air condi-
tioning system may not operate correctly.

Maintenance and care
Your Lexus is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise.
●If the tire pressure drops below a predet ermined level, the driver is warned by
a screen display and a warning light. ( P. 527)
●The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P. 96)
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pr essure warning valves and transmitters
must also be installed.
When new tire pressure wa rning valves and transmitters are installed, new ID
codes must be registered in the tire pressure warning computer and the tire
pressure warning system must be initia lized. Have tire pressure warning valve
and transmitter ID codes registered by your Lexus dealer. ( P. 492)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following circum-
stances:
●When rotating the tires in above situation.
●When the set tire pressure has been changed before towing. ( P. 571)
When the tire pressure warning system is initialized, the current tire inflation
pressure is set as the benchmark pressure.

Maintenance and care
■When to replace your vehicle’s tires
Tires 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 location of
a cut or other damage
If you are not sure, consult with your Lexus dealer.
■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 proper ly. After driving for about 20 minutes, the
tire pressure warning light comes on after blinking for 1 minute to indicate a system mal-
function.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has seldom
or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning syst em does not replace routine tire inflation pressure checks.
Make sure to check tire inflat ion pressure as part of your routine of daily vehicle checks.
■Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replacement
tire is greater than 1/2 of the Gross Axle We ight Ratings (GAWR) of either the front axle
or the rear axle, whichever 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 men-
tioned on the sidewall of the tire. ( P. 575)
