Hyundai Tucson: Blind-Spot Collision Warning (BCW) / Blind-Spot Collision-Avoidance Assist Malfunction and Limitations

Blind-Spot Collision-Avoidance Assist malfunction

When the Blind-Spot Collision-Avoidance Assist is not working properly, the "Check Blind-Spot Safety system" warning message may appear, and the warning light may illuminate on the instrument cluster. Have the vehicle inspected by an authorized HYUNDAI dealer.

When the side view mirror warning light is not working properly, the "Check side view mirror warning light" warning message may appear, and the warning light may illuminate on the instrument cluster. Have the vehicle inspected by an authorized HYUNDAI dealer.

Blind-Spot Collision-Avoidance Assist disabled

If the rear corner radar is blocked or covered, or when the rear bumper around the rear corner radar or sensor is covered by any foreign material, such as snow, rain, or dirt, or when a trailer or hitch mounted carrier is installed, the detecting performance may decrease and temporarily limit or disable Blind- Spot Collision-Avoidance Assist.

The "Blind-Spot Safety system disabled. Radar blocked" warning message may appear on the instrument cluster.

The function operates normally when such foreign material, trailer, or carrier is removed, and the engine is restarted.

If the function does not operate normally after anything covering or blocking the sensors is removed, have the vehicle inspected by an authorized HYUNDAI dealer.

WARNING

• Blind-Spot Collision-Avoidance Assist may not operate properly even if there is no warning message or warning light on the instrument cluster.
• Blind-Spot Collision-Avoidance Assist may not operate properly in open areas where no objects are detected (e.g. empty parking lot) or when the detecting sensors are blocked right after turning on the engine.
• Always turn off Blind-Spot Collision- Avoidance Assist when towing a trailer or using a hitch mounted carrier.

Limitations of Blind-Spot Collision- Avoidance Assist

Blind-Spot Collision-Avoidance Assist may not operate normally or the function may operate unexpectedly if:

• There is inclement weather, such as heavy snow, heavy rain, etc.
• The rear corner radar or the area near the rear corner radar is covered by snow, water, or dirt.
• The rear corner radar or the area near the rear corner radar is blocked by a vehicle, wall, or pillar.
• The temperature near the rear corner radar is very hot or cold.
• You are driving on a highway access road or through a tollbooth.
• The road pavement (or the ground near your vehicle) contains metallic components (i.e. possibly due to subway construction).
• There is a fixed object near your vehicle, such as sound barriers, guardrails, central dividers, entry barriers, streetlights, signs, tunnels, walls, etc.
• You are driving on a narrow road where trees or grass are overgrown.
• You are driving in large, open areas where there are few vehicles or structures (e.g. desert, meadow, empty parking lot).
• You are driving on a wet road.
• The other vehicle drives very close behind your vehicle, or passes by your vehicle in close proximity.
• The speed of the other vehicle is so fast that it passes by your vehicle in a short time.
• Your vehicle passes another vehicle.
• Your vehicle changes lanes.
• Your vehicle has started at the same time as the vehicle next to you and has accelerated.
• The vehicle in the next lane moves two lanes away from you, or the vehicle moves two lanes away to the next lane.
• A trailer or hitch mounted carrier is installed and it blocks the rear corner radar.
• The area near the rear corner radar is covered with objects, such as bumper sticker, bumper guard, bike rack, etc.
• The bumper around the rear corner radar has been damaged or modified, and the radar is out of position.
• Your vehicle height is lower or higher than normal due to heavy loads, abnormal tire pressure, etc.

Blind-Spot Collision-Avoidance Assist may not operate normally or may operate unexpectedly when the following objects are detected:

• A motorcycle or bicycle
• A vehicle such as flat trailer
• A big vehicle such as bus or truck
• A moving obstacle such as pedestrian, animal, shopping cart, or baby stroller
• A vehicle with lower height, such as sports car

Blind-Spot Collision-Avoidance Assist may not assist braking when:

• Your vehicle severely vibrates while driving over a bumpy road, uneven road, or concrete patch.
• You are driving on a slippery surface due to snow, water puddle, ice, etc.
• The tire pressure is low or any tire is damaged.
• There is an issue with the braking system.
• Your vehicle makes abrupt lane changes.

Information

For more information on limitations of the front view camera, refer to the "Forward Collision-Avoidance Assist (FCA)" section in this chapter.

WARNING

Driving curves

Blind-Spot Collision-Avoidance Assist may not detect a vehicle in an adjacent lane when driving on curves and may not activate a warning or brake your vehicle.

Always check road conditions, and if necessary, take appropriate actions to drive safely.

Blind-Spot Collision-Avoidance Assist may detect a vehicle in the same lane when driving on curves and activate a warning or brake your vehicle.

Always check road conditions, and if necessary, take appropriate actions to drive safely.

Driving where the road is merging/ dividing

Blind-Spot Collision-Avoidance Assist may not detect a vehicle in an adjacent lane when the road merges or divides and may not activate a warning or brake your vehicle.

Always check road conditions, and if necessary, take appropriate actions to drive safely.

Driving on hills

Blind-Spot Collision-Avoidance Assist may not detect a vehicle in an adjacent lane or may incorrectly detect the ground or another object when driving on hills and activate a warning or brake your vehicle.

Always check road conditions, and if necessary, take appropriate actions to drive safely.

Driving where the heights of the lanes are different

Blind-Spot Collision-Avoidance Assist may not operate properly when driving where the heights of the lanes are different. The function may not detect a vehicle on a road with a different lane height (underpass joining section, grade separated intersections, etc.) and not activate a warning or brake your vehicle.

Always check road conditions, and if necessary, take appropriate actions to drive safely.

WARNING

• Blind-Spot Collision-Avoidance Assist may not operate normally if there is interference from strong electromagnetic waves.
• Blind-Spot Collision-Avoidance Assist may not operate right after your vehicle is started or when the front view camera and rear corner radars are initialized.
