■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:

NOTICE
■Cleaning detergents
●Do not use the following types of detergent, as they may discolor the vehicle inte-
rior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline, alkaline
or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
●Do not use polish wax or polish cleaner. The instrument panel’s or other interior
part’s painted surface may be damaged.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces:
●Remove any dust or dirt from leather surfaces immediately.
●Do not expose the vehicle to direct sun light for extended periods of time. Park
the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the upholstery, as
they may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into
contact with electrical components such as the audio system above or under the
floor of the vehicle. Water may also cause the body to rust.
■When cleaning the inside of the windshield (vehicles with LKA [Lane-Keeping
Assist])
Be careful not to touch the camera sensor ( P. 344).
If the camera is accidentally scratched or hit, LKA may not operate properly or
may cause a malfunction.
■Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause damage to
the rear window defogger heater wires or antenna. Use a cloth dampened with
lukewarm water to gently wipe the window clean. Wipe the window in strokes
running parallel to the heater wires or antenna.
●Be careful not to scratch or damage the heater wires or antenna.

6-2. Maintenance
●Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
The interval for scheduled maintenance is determined by the odometer reading
or the time interval, whichever comes first, shown in the schedule.
Maintenance beyond the last period should be performed at the same intervals.
●Where to go for maintenance service?
It makes good sense to take your vehicle to your local Lexus dealer for mainte-
nance service as well as other inspections and repairs.
Lexus technicians are well-trained specialists receiving the latest service informa-
tion through technical bulletins, service tips and in-dealership training programs.
They learn to work on Lexus before they work on your vehicle, rather than while
they are working on it. Doesn’t that seem like the best way?
Your Lexus dealer has invested a lot of money in special Lexus tools and service
equipment. It helps them to do the job better and at less cost.
Your Lexus dealer’s service department will perform all of the scheduled mainte-
nance on your vehicle reliably and economically.
Rubber hoses (for cooling and heater system, brake system and fuel system)
should be inspected by a qualified technician according to the Lexus mainte-
nance schedule.
Rubber hoses are particularly important maintenance items. Have any deterio-
rated or damaged hoses replaced immediately. Note that rubber hoses will dete-
riorate with age, resulting in swelling, chafing or cracking.
Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance are essential. Lexus recommends the following mainte-
nance:

■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following situa-
tions, oil consumption may increase, and engine oil may need to be refilled in
between oil maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or after
replacing the engine
●If low quality oil or oil of an inappropriate viscosity is used
●When driving at high engine speeds or with a heavy load, or when driving while
accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently through
heavy traffic
CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammation and skin cancer, so care should be taken to avoid
prolonged and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in household trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.
●Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
●Avoid overfilling, or the engine could be damaged.
●Check the oil level on the dipstick every time you refill the vehicle.
●Be sure the engine oil filler cap is properly tightened.

■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life
hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized
water. (Minimum temperature: -35 C [-31F])
For more details about engine coolant, contact your Lexus dealer.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock and
water pump.
If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in
the cooling system.
CAUTION
■When the engine is hot
Do not remove the engine coolant reservoir cap. ( P. 644)
The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of water
and antifreeze must be used to provide proper lubrication, corrosion protection
and cooling. Be sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
