4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Before washing the vehicle:
•Fold the mirrors.
• Turn off the power back door system (if equipped).
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
●In certain automatic car washes, the rear spoiler may interfere with machine
operation. This may prevent the vehicle from being cleaned properly or result in
damage to the rear spoiler.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the
windows and the air suspension unit (if equipped).
●Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
Perform the following to protect the vehicle and maintain it in prime condi-
tion:
●Working from top to bottom, liberally 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 thor-
oughly 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.

■Aluminum wheels
●Remove any dirt immediately by using a neutral 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.
CAUTION
■When cleaning the windshield
●When the upper part of the windshield where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close to the raindrop sensor
●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps into the
raindrop sensor
■Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in , the wipers
may operate unexpectedly in the following
situations, and may result in hands being
caught or other serious injuries and cause
damage to the wiper blades.

NOTICE
■To prevent paint deterioration and corrosion on the body and components (alu-
minum wheels etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If you see coal tar or tree sap 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 by 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 on the surfaces of the lights.
Wax may cause damage to the lenses.
■To prevent damage to the windshield wiper arms
When lifting the wiper arms away from the windshield, pull the driver side wiper
arm upward first, and repeat for the passenger side. When returning the wipers to
their original position, do so from the passenger side first.
■When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in , the wipers may operate and the wiper blades may
be damaged.

RX350/270_EE
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and the tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional. (→P. 4 8 6 )
Vehicles with a full-size spare tire
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Lexus recom-
mends that you rotate your tires
approximately at the following
intervals:
2WD models:
Every 10000 km (6000
miles)
AW D m o d e l s :
Every 5000 km (3000
miles)
Vehicles with tire pressure
warning system: Do not fail to
initialize the tire pressure warn-
ing system after tire rotation.
■The tire pressure warning system (if equipped)
Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise. (→P. 546)

Maintenance and care
RX350/270_EE
■When to replace your vehicle’s tires
Tires should be replaced if:
●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 any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
■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 10
minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a
system malfunction.
■Tire life
●Standard tire over 6 years old must be checked by a qualified technician even if
they have seldom or never been used or damage is not obvious.
●The compact spare tire could be deformed gradually in the long term even if
you don't use it. Be sure to have the compact spare tire checked by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional if it is over 5 years.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■If the tread on snow tires wears down 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost

4-3. Do-it-yourself maintenance
RX350/270_EE
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters
and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitter, contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional as the tire pressure warning valves and trans-
mitters may be damaged if not handled correctly.
●When replacing tire valve caps, do not use tire valve caps other than those speci-
fied. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional
or other qualified service shop as soon as possible. Make sure to replace the tire
pressure warning valve and transmitter when replacing the tire. (→P. 4 8 4 )
■Driving on rough roads
Take particular care 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 vehicle’s wheels and body.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may occur
and result in an accident causing death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Poor sealing of the tire bead
●Wheel deformation and/or tire separation
●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and cause air leak-
age, which could result in an accident. If the caps are lost, replace them as soon as
possible.
