WARNING
●If the 12-volt battery’s voltage decreases or there is a disconnection, the system may not be able to access
the Public Safety Answering Point (PSAP).
■When replacing DCM to a new one
ERA-GLONASS have to be activated. Contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer.
■For your safety
●Please drive safely.The function of this system is to assist
you in making the Emergency Call in case of accidents as traffic accidents or sudden medical emergencies, and it
does not protect the driver or the pas- sengers in any way. Please drive safely and fasten your seatbelts at all times
for your safety.
●In case of an emergency, make lives the top priority.
●If you smell anything burning or another unusual smell, do not stay
inside the vehicle and evacuate to a safe area immediately.
●Since the system detects shocks, the automatic reporting may not always
occur synchronized with the operation of the airbag system. (If the vehicle is bumped from behind, etc.)
●The airbag may not inflate even in case
of an accident, if it does not involve high impact. In such cases, the system may not make emergency calls auto-
matically. The system may also not make automatic emergency calls even if the airbag has been inflated. If any of
these should occur, please report to the Public Safety Answering Point (PSAP) by operating the “SOS” but-
ton.
●For safety, do not make the Emergency Call while driving.
Making calls during driving may cause mishandling of th e steering wheel, which may lead to unexpected acci-
dents. Stop the vehicle and confirm the safety of the area before making the Emer-
gency Call.
●When changing fuses, please use fuses that correspond to the described stan-dard.
If you use fuses other than those described, it may cause ignition or smoke in the circuit and may lead to a
fire.
●Using the system while there is smoke or an unusual smell may cause a fire. Stop using the system immediately and
consult any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
NOTICE
■To prevent damage
Do not pour any liquid on to the “SOS”
button panel etc. and make any impact to it.
■If the “SOS” button panel malfunc-tions
It may not be able to make the Emer-
gency Call or inform you of the correct condition of the system. If the “SOS” but-ton panel has been broken, please con-
sult any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.

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 the wiper switch is in AUTO, the wipers may operate and the wiper blades may be damaged.
