■Automatic Collision Notification
If any airbag deploys, the system is designed to automatically call the Public
Safety Answering Point (PSAP).* The responding agent receives the vehicle’s
location and attempts to speak with the vehicle occupants to assess the level
of emergency. If the occupants are unable to communicate, the agent auto-
matically treats the call as an emer gency, contacts the nearest emergency
services provider to describe the situation, and requests that assistance be
sent to the location.
*: In some cases, the call cannot be made.( P. 580)
■Emergency Assistance Button (“SOS”)
In the event of an emergency, push the “SOS” button to reach the Public
Safety Answering Point (PSAP). The answering agent will determine your
vehicle’s location, assess the emergency, and dispatch the necessary assis-
tance required.
If you accidentally press the “SOS” button, tell the agent that you are not experi-
encing an emergency.
When the engine switch is turned to IGNITION ON mode, the red indicator
light will illuminate for 10 seconds and then the green indicator light will illumi-
nate for 2 seconds, indicating that the syst em is enabled. The indicator lights indi-
cate 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 malfunc-
tioning or the backup battery may be depleted. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
The service life of the backup battery is 3 years or more.

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 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 w ill 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 th e “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 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 sys- tem may not be able to connect to the cellular network and the call may finish with-
out connecting. The red indicator light w ill 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 any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

■Note for a smart entry & start system
●If the door handle becomes wet while the electronic key is within the effective range, the door may lock and unlock repeatedly. Place the key in a position 2 m (6 ft.) or more
separate from the vehicle while the vehicle is being washed. (Take care to ensure that the key is not stolen.)
●If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors.
●Set the electronic key to battery-saving mode to disable the smart entry & start system. ( P. 169)
■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 as used on the paint.
●Do not use detergent on the wheels when th ey are hot, for example after driving for long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coating.
• 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 co ntain abrasives when cleaning the windows.
• Do not use any metallic objects to remove condensation build up.

WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energize d. To avoid death or serious injury, observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc., right after driving
as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel andbattery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted sur- faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may auto- matically start to run if the air conditioning is on and/or the coolant temperature is high. ( P. 607)
■Safety glasses
Wear safety glasses to prevent flying or fa lling material, fluid spray, etc., from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high.If the reservoir needs frequent refillin g, it may indicate a serious problem.
