■If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY” indicator does not come on, contact any au thorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light (P. 577)
go off. If there is only a smal l amount of fuel, the hybrid system may not be able to start. (The standard amount of fuel is about 10 L [2.7 gal., 2.2 Imp. gal.], when the vehicle is on
a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when
the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a li mited service life. The lifespan of the hybrid
battery (traction battery) can change in acco rdance with driving style and driving condi-
tions.
■Declaration of conformity
This model conforms to hydrogen emission s according to regulation ECE100 (Battery
electric vehicle safety).

■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 o ccupants are unable to communicate, the agent auto-
matically treats the call as an emergency, contacts the nearest emergency
services provider to describe the situ ation, and requests that assistance be
sent to the location.
*: In some cases, the call cannot be made.( P. 498)
ERA-GLONASS
: If equipped
ERA-GLONASS is a telematics service th at uses Global Navigation Satellite
System (GLONASS) data and embedded cellular technology to enable the
following emergency calls to be ma de: Automatic emergency calls (Auto-
matic Collision Notificati on) and manual emergency calls (by pressing the
“SOS” button). This service is required by Eurasian Customs Union Regula-
tions.

■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 power switch is turned to ON mode, the red indicator light will illumi-
nate for 10 seconds and then the green indicator light will illuminate for 2 sec-
onds, indicating that the system is en abled. 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
power switch is turned to ON mode, the system may be malfunctioning or the
backup battery may be depleted. Cont act any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer.
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 su ch as nearby public phones.
• It may sometimes be difficult to connect to the public Safety Answering Point (PSAP) even in the reception area of t he 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 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 brok en, the Emergency Call cannot be made.
• During the Emergency Call, the system makes repeated attempts to connect to
the Public Safety Answerin g 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 ce llular network and the call may finish with-
out connecting. The red indi cator 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 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. Contac t any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
