• The ground clearance of the vehicle ahead is low or high.
• A vehicle, pedestrian, or cyclist suddenly crosses in front of your vehicle.
• The bumper around the front radar is impacted or damaged, or the front radar is out of position.
• The temperature around the front radar is too high or too low.
• Driving through a tunnel or under an iron bridge.
• Driving in large open areas where there are few vehicles or structures (for example, desert, meadow, suburbs, etc.).
• Driving near objects containing metal, such as construction zones, railways, etc.
• Nearby material that reflects very well to the front radar, such as guardrails, a closely parked vehicle, etc.
• A cyclist ahead riding a bicycle made of material that does not reflect well to the front radar.
• The vehicle ahead is detected late.
• The vehicle ahead is suddenly blocked by an obstacle.
• The vehicle ahead suddenly changes lanes or decelerates sharply.
• The vehicle ahead is curved due to its shape.
• The speed of the vehicle ahead is high or low.
• The vehicle ahead steers in the direction opposite to your vehicle to avoid a collision.
• When a vehicle is ahead, your vehicle changes lanes at low speed.
• The vehicle ahead is covered with snow.
• You are leaving or entering an alley.
• Unstable driving.
• You are at a roundabout and the vehicle ahead is not detected.
• You are continuously driving in a circle.
• The vehicle ahead has an unusual shape.
• The vehicle ahead is driving uphill or downhill.
• A pedestrian or cyclist is not fully detected, for example, when the pedestrian is leaning or not walking fully upright.
• A pedestrian or cyclist wears clothing or equipment that makes it difficult to identify as a pedestrian or cyclist.

The illustration above shows an example of how the front view camera may recognize a vehicle, pedestrian, and cyclist.

• A pedestrian or cyclist ahead is moving very fast.
• A pedestrian or cyclist ahead is short or is in a low posture.
• A pedestrian or cyclist ahead has limited mobility.
• A pedestrian or cyclist ahead is crossing the direction of travel.
• There is a group of pedestrians, cyclists, or a large crowd ahead.
• A pedestrian or cyclist wears clothing that easily blends into the background, making it difficult to detect.
• A pedestrian or cyclist is difficult to distinguish from similarly shaped structures in the surroundings.
• You are driving past a pedestrian, cyclist, road sign, structure, etc. near an intersection.
• Driving in a parking lot
• Driving through a barrier gate, construction site, unpaved road, partially paved road, rough road, speed bumps, etc.
• Driving on a sloped road, curved road, etc.
• Driving past a roadside with trees or street lights
• Excessive vehicle vibration during driving due to adverse road conditions
• The height of your vehicle is lowered or raised due to heavy loads, incorrect tire pressure, etc.
• Driving on a narrow road where trees or grass overgrow.
• Interference from electromagnetic waves, such as driving in an area with strong radio waves or electrical interference

WARNING

• Driving on a curve

Forward Collision-Avoidance Assist may not detect other vehicles, pedestrians, or cyclists ahead of you on curved roads, which adversely affects sensor performance. This may result in no warning or braking assistance when needed.

When driving through a curve, maintain a safe braking distance and, if necessary, steer the vehicle and depress the brake pedal to reduce speed and maintain a safe distance.

Forward Collision-Avoidance Assist may detect a vehicle, pedestrian, or cyclist in an adjacent lane or outside the driving lane when driving on a curved road.

If this occurs, the system may issue an unnecessary warning and apply the brakes. Always check the traffic conditions around the vehicle.

• Driving on a slope

Forward Collision-Avoidance Assist may not detect other vehicles, pedestrians, or cyclists ahead of you when driving uphill or downhill, which adversely affects sensor performance.

This may result in an unnecessary warning or braking assistance, or no warning or braking assistance when necessary.

In addition, the vehicle speed may decrease rapidly when a vehicle, pedestrian, or cyclist ahead is suddenly detected.

Always watch the road when driving uphill or downhill, and if necessary, steer the vehicle and depress the brake pedal to reduce driving speed and maintain a safe distance.

• Lane Change

[A]: Your vehicle, [B]: Vehicle changing lanes

When a vehicle moves into your lane from an adjacent lane, it may not be detected by the sensor until it is within the sensor detection range. Forward Collision-Avoidance Assist may not immediately recognize a vehicle when it changes lanes abruptly. In this case, you must maintain a safe braking distance and, if necessary, steer the vehicle and depress the brake pedal to reduce driving speed and maintain a safe distance.

[A]: Your vehicle, [B]: Vehicle changing lanes, [C]: Vehicle in the same lane

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

• Vehicle Detection

If the vehicle ahead is carrying cargo that protrudes rearward from the cab, or if the vehicle ahead is higher than your vehicle, extra caution is necessary. Forward Collision-Avoidance Assist may not be able to detect cargo protruding from the vehicle. In these cases, you must maintain a safe braking distance from the rearmost object and, if necessary, steer the vehicle and depress the brake pedal to reduce driving speed and maintain a safe distance.

WARNING

• When towing a trailer or another vehicle, we recommend that Forward Collision-Avoidance Assist be turned off for safety reasons.
• Forward Collision-Avoidance Assist may not work properly if objects with shapes or characteristics similar to vehicles, pedestrians, and cyclists are detected.
• Forward Collision-Avoidance Assist does not operate for bicycles, motorcycles, or wheeled objects such as luggage bags, shopping carts, or strollers.
• Forward Collision-Avoidance Assist may not operate normally if strong electromagnetic waves cause interference.
• Forward Collision-Avoidance Assist may not operate for 15 seconds after the vehicle is started or the front camera is initialized.
