For safety and security
■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 vehicl\
e 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) in the United Stat es, 1-877-539-8777 in Pu erto Rico or 1-800-265-
3987 in Canada, 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.
■Emergency Assistance Button (“SOS”)
In the event of an emergency on the ro ad, push the “SOS” button to reach the
Safety Connect response center. Th e 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 response-center agent that you
are not experiencing an emergency.
■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds GP S data to the already included war-
ranty-based Lexus roadside service.
Subscribers can press the “SOS” button to reach a Safety Connect response-
center agent, who can help with a wide range of needs, such as: towing, flat
tire, fuel delivery, etc. For a descript ion of the Roadside Assistance services
and their limitations, please see the Safety Connect Terms and Conditions,
which are available at Lexus.com.
