NOTE:
 After the operating conditions of warning are satisfi
ed, the warning continues until the vehicle speed reaches
approximately 29 km/h (18 MPH)
 The BSW system may not function properly, depending on the situation. Refer to DAS-417, "
Precautions for
Blind Spot Warning".
BULB CHECK ACTION AND FAIL-SAFE INDICATION
*: If BSW initial state is ON, warning systems ON indicator continues turned ON.
NOTE:
 The condition is seen regardless BSW system status (ON/OFF).
 If either of the side radars is in factor y-default mode, the BSW warning lamp blinks.
 New side radars are in factory-default mode.

BSW INITIAL STATE CHANGE
CAUTION:
Never change BSW initial state “ON” ⇒ “OFF” without the con sent of the customer.
BSW initial state can be changed.
 BSW initial ON* - BSW function is automatic ally turned ON, when the ignition switch OFF ⇒ ON.
 BSW initial OFF - BSW function is still 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 changes completed.

FAIL-SAFE CONTROL BY DTC
If a malfunction occurs in the side radar, ADAS control unit cancels the control. Then the BSW warning lamp in
the combination meter illuminates.
TEMPORARY DISABLED STATUS AT BLOCKAGE
When the side radar is blocked, the operation is tempor arily cancelled. Then BSW warning lamp in combina-
tion meter blinks. Also, under the following conditions, the operation may be temporarily cancelled.
 The side radar may be blocked by temporary ambient c onditions such as splashing water, mist or fog.
 The blocked condition may also be caused by objects such as ice, frost or dirt obstructing the side radar.
