FUNCTION DESCRIPTION
• The BSW system can help alert the driver of ot her vehicles in adjacent lanes when changing lanes.
• The BSW system uses rear view camera near the rear bumper to detect vehicles in an adjacent lane.
• The rear view camera can detect vehicles on either si de of vehicle within the detection zone shown as illus-
trated.
• This detection zone starts from the back of the v ehicle and extends approximately 3.0 m (10 ft) behind the
rear bumper, and approximately 13.0 m (10 ft) sideways.
• The BSW system operates above approximately 32 km/h (20 MPH).
• If the rear view camera detects vehicles in the detec tion zone, the Blind Spot Warning indicator illuminates.
• If the driver then activates the turn signal, a buzzer will sound twice and the Blind Spot Warning indicator will blink.
NOTE:
A buzzer sounds if the rear view camera has already detected vehicles when the driver activates the turn
signal. If a vehicle comes into the detection zone after t he driver activates the turn signal, then only the Blind
Spot Warning indicator blinks and no buzzer sounds.
BSW SYSTEM OPERATION DESCRIPTION
• Control unit enables BSW system.
• The control unit turns on the BSW system w hen the warning systems switch is turned ON.
• Rear view camera detects a vehicle in the adjacent l ane, and transmits the vehicle detection signal to control
unit.
• Control unit starts the control as follows, based on a vehicle detection signal, turn signal and dimmer signal transmitted from BCM via CAN communication:
- Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal transmission to rear view camera.
- Buzzer signal transmission to warning buzzer.
• Rear view camera transmits an indicator operation signal to the Blind Spot Warning indicator according to
Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal.

REAR VIEW CAMERA HANDLING
The rear camera unit “1” for the LDW/BSW sy stems is located above the rear license plate.
To keep the proper operation of the LDW systems and prev ent a system malfunction, be sure to observe the
following:
• Always keep the camera lens clean. Be careful not to damage the nozzle of the automatic washer and
blower.
• Do not attach ”license plate accessories” that reflect light.
• Do not strike or damage the areas around the camera unit.
BLIND SPOT WARNING (BSW)
• BSW system is not a replacement for proper drivi ng procedure and is not designed to prevent contact with
vehicles or objects. When changing lanes, always use the side and rear mirrors and turn and look in the
direction you will move to ensure it is safe to change lanes. Never rely solely on the BSW system.
• The camera unit may not detect properly under the following conditions:
- When towing a trailer.
- When strong light enters the camera unit. (For exampl e, direct sunlight or headlight from the rear.)
- When ambient light changes instantly. (For example, when the vehicle enters or exits a tunnel or passes
under a bridge.)
• Automatic washer and blower may not be able to secu re detection capability when excessive dirt adheres on
the camera lens.
• Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime sound, and it
may not be heard.
• The camera unit may not be able to detect when certain objects are present such as:
- Pedestrians, bicycles, animals.
- Several types of vehicles such as motorcycles.
- Oncoming vehicles.
- A vehicle approaching rapidly from behind
- A vehicle which your vehicle overtakes rapidly.
• The camera unit may not be able to detect properly when your vehicle travels beside the middle section of a
vehicle with a long wheelbase (e.g., trailer truck, semi-trailer, tractor).
• The camera unit is 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.
• The camera unit may detect reflection image of vehicles or roadside objects that are not actually in the
detection zone, especially when the road is wet.

CONSULT Function (AVM)INFOID:0000000009951646
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and no-start condition.
