Nissan Murano: Traffic Sign Recognition (TSR) (if so equipped) / System malfunction
If the TSR system malfunctions, it will be
turned off automatically and the LDW indicator
(orange) will illuminate in the vehicle
information display.
Action to take:
If the LDW indicator (orange) illuminates in
the display, pull off the road at a safe location
and stop the vehicle. Turn the engine
off and restart the engine. If the LDW indicator
(orange) continues to illuminate,

started, the TSR system may be deactivated
