IN CASE OF AN EMERGENCY
NOTICE
You must provide the Lexus Link operator with your
Lexus Link PIN (Personal Identification Number) or
personal security word, before they lock/unlock your
vehicle. However, the Lexus Link System will not be
able to lock or unlock your vehicle if it has been parked
for 48 hours or more after the ignition is turned off.
Upon subscription expiration, all Lexus Link services
(i.e. automatic notification, emergency call functions,
service call functions) are deactivated.
If you must break a window to get in, we suggest breaking the
smallest side window because it is the least expensive to
replace. Be extremely cautious to avoid glass cuts.
