When contacting the response center
You may be unable to contact the resp onse center if the network is busy.■
Safety Connect backup battery depletion
An exclusive backup battery is built in to assist the Automatic Collision Notification,
which is activated when impact above a certain level is applied to the vehicle, or when the
airbags operate. This battery is a primary ba ttery, and cannot be recharged. The red LED
indicator will flash to indicate that the battery should be replaced.
The backup battery will need to be replaced if the Automatic Collision Notification oper-
ates for 60 seconds or more. For re placement, consult yo ur Lexus dealer.
When the engine switch is turned to IGNITION ON mode, the red indicator
light comes on for 2 seconds then turns off. Afterward, the green indicator light
comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage conditions: ●
Green indicator light on = Active service ●
Green indicator light flashing = Safety Connect call in process●
Red indicator light (except at vehicle 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 re sponse center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicle occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be sent to the location. ■
Stolen Vehicle Location
If your vehicle is stolen, Safety Conn ect can work with local authorities to
assist them in locating and recovering the vehicle. After filing a police report,
call the Safety Connect response ce nter at 1-800-25-LEXUS (1-800-255-
3987) and follow the prompts for Safety Connect to initiate this service.
In addition to assisting law enforcemen t with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle locatio n data may, under certain circum-
stances, be shared with third parties to locate your vehicle. Further informa-
tion is available at Lexus.com.Safety Connect LED light Indicators
