■Handling the radar sensor
Blind Spot Monitor sensors ar e installed behind the left and right sides of the rear
bumper respectively. Observe the following to ensure the Blind Spot Monitor can
function correctly.
●Do not subject a sensor or its surrounding area on the rear bumper to a strong
impact.
If a sensor is moved even slightly off po sition, the system may malfunction and vehi-
cles may not be detected correctly.
In the following situations , have your vehicle inspected by your Lexus dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is sc ratched or dented, or part of them has
become disconnected.
●Do not disassemble the sensor.
●Do not attach stickers to the sensor or surrounding area on the rear bumper.
●Do not modify the sensor or surrounding area on the rear bumper.
●Do not paint the rear bumper any colo r other than an official Lexus color.

warning message (P. 471) will be displayed.
In this situation, clear off the dirt or snow and
drive the vehicle with the operation condi-

Maintenance and care
RC350_RC300 AWD_RC300_RC F_U(OM24748U)
WARNING
■Precautions regarding the exhaust pipes
As exhaust gases cause the exhaust pipes to become quite hot, do not touch the
exhaust pipes while the engine is running or immediately after the engine is turned off.
When washing the vehicle, be careful not to touch the exhaust pipes until they have
cooled sufficiently, as touching hot exhaust pipes can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunction. If
this occurs, consult your Lexus dealer.
NOTICE
■Application of coatings to the vehicle body (vehicles with CFRP parts)
Do not apply any kind of coating to the vehicle body as doing so may damage the paint
or reduce its durability.
■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 dead insects, insect droppings or bird droppings are present on the paint surface
• 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 with 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 the 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 to 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 (vehicle s with rain-sensing windshield wipers)
Set the wipers to the intermittent windshield wipers. ( P. 236)
