■Languages
The Safety Connect response center will

Safety Connect system will offer voice
prompts in English, Spanish, and French.
Please indicate your language of choice
when enrolling.
■When contacting the response center
You may be unable to contact the response
center if the network is busy.
When the engine switch is turned to
IGNITION ON mode, the red indica-
tor light comes on for 2 seconds then
turns off. Afterward, the green indica-
tor light comes on, indicating that the
service is active.
The following indicator light patterns
indicate specific system usage condi-
tions:
 Green indicator light on = Active
service
 Green indicator light flashing =
Safety Connect call in process
 Red indicator light (except at vehi-
cle start-up) = System malfunction
(contact your Lexus dealer)
 No indicator light (off) = Safety
Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or
severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the agent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
Safety Connect LED light Indi-
cators
