WARNING

  • You are driving on a curved road.

    OCV054214N_4
    OCV054215N_4

    Forward Collision-Avoidance Assist may not detect other vehicles, powered two-wheelers, pedestrians or cyclists in front of you when driving on curved roads adversely affecting the performance of the sensors. This may result in no warning, braking assist or steering assist (if equipped) when necessary.

    When driving on a curve, you must maintain a safe braking distance and, if necessary, steer the vehicle and engage the brake pedal to reduce your speed.

    Forward Collision-Avoidance Assist may detect a vehicle, motorcyclist, pedestrian, or cyclist in the adjacent lane or outside of the lane when you drive on a curved road.

    If this occurs, Forward Collision-Avoidance Assist may unnecessarily warn the driver and control the brake or steering (if equipped). Always check the traffic conditions around the vehicle.

  • Driving on an incline

    OCV054216N_4

    Forward Collision-Avoidance Assist may not detect other vehicles, motorcyclists, pedestrians, or cyclists ahead of you when you drive uphill or downhill, and adversely affect sensor performance.

    This may result in unnecessary warning, braking assist, steering assist (if equipped) or no warning, braking assist, steering assist (if equipped) when necessary.

    The vehicle speed may rapidly decrease when a vehicle, powered two-wheeler, pedestrian or cyclist ahead is suddenly detected.

    Always have your eyes on the road while driving uphill or downhill and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

  • Changing lanes

    OCV105005N
    OCV105006N

    1. Your vehicle

    2. Lane changing vehicle

    3. Same lane vehicle

    When a vehicle (2) moves into your lane from an adjacent lane, it cannot be detected by the sensor until it is in the sensor’s detection range.

    Forward Collision-Avoidance Assist may not immediately detect the vehicle when the vehicle changes lanes abruptly. In this case, you must maintain a safe braking distance, and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

    When a vehicle (2) in front of you merges out of the lane, Forward Collision-Avoidance Assist may not immediately detect the vehicle (3) that is now in front of you. In this case, you must maintain a safe braking distance, and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

  • Detecting a vehicle

    OCV054105N_2

    If the vehicle ahead of yours has cargo extending backward from the cab or high ground clearance, pay special attention. Forward Collision-Avoidance Assist may not be able to detect the cargo extending from the vehicle. In this case, you must maintain a safe braking distance from the rearmost object and, if necessary, steer your vehicle and engage the brake pedal to reduce your speed.

  • When you are towing a trailer or another vehicle, turn OFF Forward Collision-Avoidance Assist for safety reasons.

  • Forward Collision-Avoidance Assist may activate if it detects objects similar to vehicles, motorcyclists, pedestrians, or cyclists.

  • Forward Collision-Avoidance Assist does not operate on bicycles, motorcycles, or smaller wheeled objects, such as luggage bags, shopping carts, or strollers.

  • Forward Collision-Avoidance Assist may not operate normally if there is strong electromagnetic interference.

  • Forward Collision-Avoidance Assist may not activate for 15 seconds after you start the vehicle or initialize the front view camera.
