LDW INITIAL STATE CHANGE
CAUTION:
Never change LDW initial state “ON” ⇒ “OFF” without the con sent of the customer.
LDW initial state can be changed.
LDW initial ON* - LDW function is automatically turned ON, when the ignition switch OFF ⇒ ON.
LDW initial OFF - LDW function is st ill OFF when the ignition switch OFF ⇒ ON.
*: Factory setting
How to change FCW/LDW/BSW initial state
1. Turn ignition switch ON.
2. Warning systems switch is OFF.
3. Push and hold warning systems switch for more than 4 seconds.
4. Buzzer sounds and blinking of the warning systems ON indicator informs that the FCW/LDW/BSW initial
state change is completed.
