Revision: 2006 July 2007 FX35/FX45
In the automatic mode
–LDW system automatically turns on, when the ignition switch is turned to the ON position.
–LDW system ON indicator located on the LDW switch illuminates, indicating that the system is on.
–To cancel LDW system, push the LDW switch to turn off LDW system ON indicator.
–To turn on the system, push LDW switch again.
In the manual mode
–LDW system is still off when the ignition switch is turned to the ON position.
–The LDW switch must be pushed to turn on the system.
To the change modes
–Push and hold LDW switch for more than 4 seconds, when LDW system ON indicator is off.
–Then LDW chime sounds and blinking of LDW system ON indicator informs that the mode change is com-
pleted.

Temporary disabled status at high temperature
–If the vehicle is parked in direct sunlight under high temperature conditions [approximately over 104 °F
(40 °C)] and then started, the LDW system may sound a chime and cancel automatically. Then LDW sys-
tem ON indicator will blink.
–When the interior temperature is reduced, the system will resume to operate automatically and the LDW
system ON indicator illuminates.
