WARNING
■When the Emergency Call may not be made
●Any of the followings may occur. In such cases, report to the Public Safety
Answering Point (PSAP) by other means such as nearby public phones.
• It may sometimes be difficult to con- nect to the Public Safety Answering Point (PSAP) even in the reception
area of the cellular phone due to the reception level, or if the line is busy.In such cases, you may not be able to
connect to the Public Safety Answer- ing Point (PSAP) and thus will not be able to make emergency calls and
report to the emergency departments even though the system tries to con-nect to the Public Safety Answering
Point (PSAP).
• When the vehicle is out of the cellular
phone service area, the Emergency Call cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator lights, microphone, speaker, DCM,
antenna, or any wires connecting the equipment.) has an abnormality, is damaged or broken, the Emergency
Call cannot be made.
• During the Emergency Call, the sys-
tem makes repeated attempts to con- nect to the Public Safety Answering Point (PSAP). However, if it cannot
connect to the Public Safety Answer- ing Point (PSAP) due to poor radio wave reception, the system may not be
able to connect to the cellular network and the call may finish without con-necting. The red indicator light will
blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.

6-1. Maintenance and care
WARNING
●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
As exhaust gases cause the exhaust
pipes and rear bumper diffusers to become quite hot, do not touch the exhaust pipes and rear bumper diffusers
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 and rear
bumper diffusers until they have cooled sufficiently, as touching hot exhaust pipes and rear bumper diffusers 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 malfunc-
tion. If this occurs, consult any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
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 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, pollen 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.
■When using an automatic car wash
Set the wiper switch to the off position.

■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus retailer

When the light comes on yellow, the assist to the power steering is restricted. When the
light comes on red, the assist to the power st eering is lost and handling operations of the steering wheel become extremely heavy. When steering wheel operations are heavier than usual, grip the steering wheel firmly and operate it using more force than usual.

cle control and result in death or serious injury.
●Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 80 km/h (50 mph).
●Check and adjust the tire inflation pressure immediately.
●If the tire pressure warning light comes on ev en after tire inflation pressure adjustment, it is probable that you have a flat tire. Have the flat tire replaced by nearest authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer.
