DAS-30, "LDW : Menu Displayed by
OPERATION DESCRIPTION
• LDW system is controlled by the front camera unit.
• When the system is turned ON, the front camera unit transmits LDW system display signal to combination
meter via CAN communication.
• The front camera unit monitors lane markers of the traveling lane.
• When judging from a lane marker detection signal that the vehicle is approaching the lane marker, the front
camera unit controls the following item to alert the driver.
- Activates warning buzzer in the sonar control unit (With sonar system) or combination meter (Without sonar
system).
- The front camera unit transmits a LDW system display signal to combination meter via CAN communication
and blinks the LDW system indicator (“icon”).
Operating Condition
• LDW system indicator (white): ON (“lane”)
When the LDW system setting on the combination meter is ON
• Vehicle speed: approximately 60 km/h (37 MPH) or more
• Turn indicator signal: After 2 seconds or more from turned OFF
NOTE:
• LDW system ON/OFF can be set on the combination meter
• After the operating conditions of warning are satisfied, the warning continues until the vehicle speed reaches
approximately 55 km/h (34 MPH)
• LDW system may not function properly, depending on the situation. Refer to

FUNCTION DESCRIPTION
• The BSW system can help alert the driver of other vehicles in adjacent lanes when changing lanes.
• The BSW system uses rear camera installed the back door finisher to detect vehicles in an adjacent lane.
• The rear camera can detect vehicles on either side of vehicle within the detection zone shown as illustrated.
• This detection zone starts from the outside mirror of vehicle and extends approximately 10 ft (3.0 m) behind
the rear bumper, and approximately 10 ft (3.0 m) sideways.
• The BSW system operates above approximately 32 km/h (20 MPH).
• If the rear camera detects vehicles in the detection zone, the BSW indicator illuminates.

If a vehicle comes into the detection zone after the driver activates the turn signal, then only the BSW indica-
tor blinks and no buzzer sounds.
OPERATION DESCRIPTION
• Around view monitor control unit enables BSW system.
• The around view monitor control unit turns on the BSW system when the turned ON by combination meter.
• Rear camera transmits the camera image signal to around view monitor control unit.
• Around view monitor control unit starts the control as follows, based on a camera image signal, turn indicator
signal and position light request signal transmitted from BCM via CAN communication:
- Buzzer drive signal transmission to sonar control unit via CAN communication. (With sonar system)
- Buzzer output signal transmission to combination meter via CAN communication. (Without sonar system)
• Around view monitor control unit transmits an indicator operation signal to the BSW indicator.
Operation Condition
• BSW system indicator (white): ON (Speaker icon ON in “Blind spot” position)
• When the vehicle drives at 32 km/h (20 MPH) or more to the forward direction.
NOTE:
BSW system ON/OFF can be set on the combination meter
