■Emergency Assistance Button (“SOS”)
In the event of an emergency, push the “SOS” button to reach the Pub-
lic Safety Answering Point (PSAP). The answering agent will determine
your vehicle's location, assess the emergency, and dispatch the neces-
sary assistance required.
If you accidentally press the “SOS” button, tell the agent that you are not expe-
riencing an emergency.
When the engine switch is turned to IGNITION ON mode, the red indi-
cator light will illuminate for 10 seconds and then the green indicator light
will illuminate for 2 seconds, indicatin g that the system is enabled. The
indicator lights indicate the following:
●If the green indicator light illuminates and stays on, the system is
enabled.
●If the green indicator light flashes, an emergency call is being made
(either automatically or manually).
●If no indicator lights illuminate, the system is not enabled.
●If the red indicator light illuminates any time other than immediately
after the engine switch is turned to IGNITION ON mode, the system
may be malfunctioning or the backup battery may be depleted. Con-
tact your Lexus dealer.
The service life of the backup battery is 3 years or more.

CAUTION
■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 connect 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 Answering
Point (PSAP) and thus will not be able to make emergency calls and report to
the emergency departments even though the system tries to connect 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, indicators,
microphone, speaker, DCM, antenna, or any wires connecting the equip-
ment.) has an abnormality, is damaged or broken, the Emergency Call cannot
be made.
• During the Emergency Call, the system makes repeated attempts to connect
to the Public Safety Answering Point (PSAP). However, if it cannot connect to
the Public Safety Answering 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 connecting. 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.
●If the 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 your Lexus dealer.

CAUTION
■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 passengers 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 vehi-
cle 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 automatically.
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” button panel button.
●For safety, do not make the Emergency Call while driving.
Making calls during driving may cause mishandling of the steering wheel, which
may lead to unexpected accidents.
Stop the vehicle and confirm the safety of the area before making the Emergency
Call.
●When changing fuses, please use fuses that correspond to the described stan-
dard. If you use fuses other than those de scribed, 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 your Lexus dealer.

6-1. Maintenance and care
●Working from top to bottom, liberally apply water to the vehicle body,
wheel wells and underside of the vehi cle 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 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.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface
scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside
temperature.
The restoration time may become shorter when the coating is warmed by applying
warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
Cleaning and protecting the vehicle exterior
Perform the following to protect the vehicle and maintain it in prime
condition:

■Automatic car washes
●Fold the mirrors before washing the vehicle. 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.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the win-
dows and the air suspension unit (if equipped).
●Before using the car wash, check that the fuel filler door on your vehicle is closed
properly.
■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 and side moldings
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long period.
Clean the windows with a soft, damp cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance has become insufficient, the coating can
be repaired. Contact your Lexus dealer.

CAUTION
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause
the electrical components etc. to catch fire.
■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 pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes and rear bumper diffusers to become quite
hot.
When washing the vehicle, be careful not to touch the pipes and 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 your Lexus dealer.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, 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.
