< SYSTEM DESCRIPTION >[BSW]
SYSTEM
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 (ADAS Control Unit)INFOID:0000000006223852
If a malfunction occurs in each s ystem, ADAS control unit cancels eac h control, sounds a beep, and turns ON
the warning lamp or indicator lamp.

Fail-safe (Side Radar)
INFOID:0000000006223853
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.

HANDLING PRECAUTION
Precautions for Blind Spot WarningINFOID:0000000006223856
SIDE RADAR HANDLING
 Side radar for BSW system is located inside the rear bumper.
 Always keep the rear bumper near the side radar clean.
 Do not attach a sticker (including transparent material), install an accessory or paintwork near the side radar.
 Do not strike or damage the areas around the side radar.
 Do not strike, damage, and scratch the side radar, especially the vent seal (gray circular) area, under repair.
PRECAUTIONS FOR BLIND SPOT WARNING
 The BSW system is not a replacement for proper driving procedure and are not designed to prevent contact
with vehicles or objects. When changing lanes, always us e the side and rear mirrors and turn and look in the
direction driver will move to ensure it is safe to change lanes. Never rely solely on the BSW system.
 The BSW system may not provide a warning for v ehicles that pass through the detection zone quickly.
 Do not use the BSW system when towing a trai ler because the system may not function properly.
 Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard.
 The side radar may not be able to detect and activate BSW when certain objects are present such as:
- Pedestrians, bicycles, animals.
- Several types of vehicles such as motorcycles.
- Oncoming vehicles.
- Vehicles remaining in the detection z one when driver accelerate from a stop.
- A vehicle merging into an adjacent lane at a speed approximately the same as vehicle.
- A vehicle approaching rapidly from behind.
- A vehicle which vehicle overtakes rapidly.
 Severe weather or road spray conditions may reduce t he ability of the side radar to detect other vehicles.
 The side radar detection zone is designed based on a standard lane width. When driving in a wider lane, the
side radar may not detect vehicles in an adjacent lane. When driving in a narrow lane, the side radar may
detect vehicles driving two lanes away.
 The side radar are designed to ignore most stationary objects, however objects such as guardrails, walls,
foliage and parked vehicles may occasionally be det ected. This is a normal operating condition.
