Blind Spot Assist with Trailer Coverage

WHAT IS BLIND SPOT ASSIST WITH TRAILER COVERAGE



Blind spot assist with trailer coverage is an extension of the lane keeping system.

It may help you identify adjacent vehicles during a lane change.

Blind spot assist provides a blind spot warning and steering assistance to help you become aware of and steer away from vehicles in your blind spot during lane changes.

When attaching a trailer, ensure you have properly set up the trailer coverage settings.   See   Blind Spot Information System

HOW DOES BLIND SPOT ASSIST WITH TRAILER COVERAGE WORK



Lane Keeping System Activation  Activate and deactivate the system using the lane keeping system button on the steering wheel.

During lane changes, the design of the blind spot assist feature detects vehicles in, or approaching, your blind spot and provides a warning, plus steering assistance to direct your vehicle back into your lane.

If a supported trailer is connected, the function is reduced to only detecting vehicles on both sides of your vehicle and trailer, extending rearward from the exterior mirrors to the end of your trailer.   See   Blind Spot Information System

When active, this system functions with or without the use of direction indicators and hazard flashers.

You must keep your hands on the steering wheel at all times.

BLIND SPOT ASSIST WITH TRAILER COVERAGE LIMITATIONS



All system limitations present in the basic lane keeping system also apply to blind spot assist.

Blind spot assist does not function under the following conditions:

  • No lane markings are detected.
  • One or both rear radar sensors become blocked or faulty.
  • You have not configured the attached trailer correctly in the trailer tow menus or you attached an unsupported trailer. The system only supports certain trailer shapes and dimensions.

Note:   Blind spot assist with trailer coverage could have reduced performance if any of the above limitations are present.

Blind spot assist may have difficulty detecting hazards under the following conditions:

  • If a vehicle is approaching in an adjacent lane at a relative speed much higher than your vehicle.
  • Bad weather conditions are present that obstruct the sensors.
  • Attaching bike or cargo racks could cause false alerts due to obstruction of the sensor.

BLIND SPOT ASSIST WITH TRAILER COVERAGE INDICATORS

Lane Keeping System with Blind Spot Assist

Diagram 1: Vehicle A uses its left turn signal preparing to change from the right lane to the middle lane. Vehicle B is already in the middle lane and just entered Vehicle A's blind spot causing the blind spot information system alert indicator to flash on the exterior mirror.

Diagram 2: The driver of Vehicle A begins to steer into the center lane not aware of Vehicle B.

Diagram 3: Blind spot assist counter steers to help alert the driver of Vehicle A to direct their vehicle back into the right lane to help avoid a possible collision with Vehicle B.

The lane keeping aid warning lamp or yellow lane marking in your instrument cluster display indicate blind spot assist activation. In addition, the blind spot information system alert indicator flashes on the exterior mirror on the same side as the detection.   See   Blind Spot Information System
