PRECAUTIONS: PRE-COLLISION SYSTEM WITH PEDESTRIAN DETECTION

Pre-Collision System (3) with Pedestrian Detection (6) is premised on safe driving by the driver. It is not a system that will avoid collisions under all conditions. Do not depend on the system or use it in place of emergency brake operation.

Pre-Collision System (3) with Pedestrian Detection (6) operation is dependent on the front-grille-mounted millimeter-wave radar and in-vehicle camera’s ability to detect and see clearly a preceding vehicle or pedestrian on relatively straight roadways, as well as the visibility/detectability of the preceding vehicle/pedestrian itself. Pre-Collision System with Pedestrian Detection may not operate if it cannot recognize a visible preceding vehicle or pedestrian. Pre-Collision System with Pedestrian Detection is not designed to detect animals. Situations such as a fogged, dirty, broken, or tinted windshield or ice, rain, snow, or sticker-covered windshield blocking the camera or laser may affect Pre- Collision System with Pedestrian Detection operation. Intense light from the front or inclement weather obstructing camera visibility or laser detection, or sharp curves in the road, may affect Pre-Collision System with Pedestrian Detection operation. Also, changes to the vehicle’s height or angle from load, suspension or tire modifications or chains may affect Pre-Collision System with Pedestrian Detection operation. Furthermore, if a preceding vehicle cannot be correctly recognized, there are cases where unneeded driver alerts / automatic braking may occur, so the driver needs to pay continuous attention to the surrounding conditions, the direction of travel and vehicle’s location on the road. Ultimately, the driver is responsible for brake input, vehicle speed, distance to a preceding vehicle and operation at all times.

VEHICLE DETECTION MAY NOT OPERATE IN THE FOLLOWING CONDITIONS:

1. When visibility to the front is poor due to bad weather (rain, snow, fog, dust raised by wind, sandstorm, blizzard, etc.)
2. When there is a sudden appearance in the forward direction of the vehicle
3. When driving around locations with sharp curves or undulations or for a period of time after turning due to camera recognition
4. When there is intense light from the front such as strong sunlight or high beams of a vehicle going the opposite direction
5. When a preceding vehicle cuts in front of you suddenly, abruptly steers, accelerates or decelerates, or is offset compared to your vehicle
6. When very close to the vehicle in front (distance of approximately 6.5 feet or less) or coming close to a preceding vehicle after making a lane change
7. Motorcycle or bicycle may not be detected
8. When driving on an up or down slope and not able to recognize a preceding vehicle
9. When vehicle angle or stance changes dramatically due to load, changes to suspension, tire pressure, etc.
10. If the rear-most surface of the preceding vehicle is small, low or irregularly high
11. When the camera or laser faces the wrong direction due to damage or misalignment
12. When something is on the sensor such as bugs, dirt, ice, etc.

In the following types of environment, the system may not be able to recognize vehicles in front and may not operate:
• If the vehicle in front does not have its taillights on at night or in a tunnel
• If camera recognition conditions are poor shortly after starting the vehicle or when the camera is hot, such as when parked in the sun
• Low light (dusk, dawn, etc.); when driving without headlights at night or in a tunnel. The system does not operate when the following operations are performed:
• While VSC13 is activated
• While the accelerator is pressed
• While the brake is pressed
• While backing up
• While driving at very high speeds

PRE-COLLISION SYSTEM (3) WITH PEDESTRIAN DETECTION (6) MAY OPERATE IN THE FOLLOWING CONDITIONS, EVEN IF A COLLISION IS NOT LIKELY:

1. When there is an obstacle or parked car at the point of entering a curve, in a curve or at an intersection
2. When passing through a narrow steel bridge or through a low ceiling area like a tunnel or parking structure
3. When there is a metal object or protrusion on the road surface or items dropped onto the road
4. When passing an opposing vehicle when turning right or left or passing an opposing vehicle around a curve
5. When driving on an uneven road or in weeds
6. When suddenly getting close to another vehicle that is driving ahead
7. Upon seeing a raised intersection, sign or advertisement board/vinyl in front of the vehicle
8. While driving up or down a slope, where metal such as a steel plate (manhole cover) is in front of the vehicle
9. Reacting to Electronic Toll Collection (ETC) bar when passing through an ETC gantry
10. When sensor direction is offset due to a strong impact near the sensor
11. When passing under a bridge or narrow tunnel
12. When turning around a curve where there is a pedestrian to the front of your vehicle (on a sidewalk)
13. While passing near a pedestrian or through a group of pedestrians
14. If a pedestrian suddenly crosses in front of your vehicle, or suddenly stops while crossing
15. When passing a leading vehicle or when a leading vehicle turns to the left or right
16. When passing through parked cars or driving between vehicles
17. When driving on a narrow road with roadside guardrails, telephone poles, trees, etc.

THE FOLLOWING TYPES OF PEDESTRIANS MAY NOT BE DETECTED OR PRE-COLLISION SYSTEM (3) WITH PEDESTRIAN DETECTION (6) MAY NOT OPERATE:

1. Pedestrians that suddenly appear from behind or alongside a vehicle
2. Pedestrians close to abrupt changes in lighting such as at tunnel exits
3. Pedestrians wearing white that reflects sunlight
4. Pedestrians walking in a group
5. Pedestrians staying close to or walking alongside a wall, fence, guardrail, vehicle or another obstacle
6. Pedestrians with brightness similar to scenery and that blend into the background
7. Pedestrians walking at high speed of approximately 5 MPH or higher
8. Pedestrians that abruptly change walking speed
9. Pedestrians colliding with the edge of the vehicle
10. Pedestrians walking on top of metal on the road surface
11. Pedestrians that are 3 feet or shorter or 6.5 feet or taller
12. Pedestrians whose silhouette is hidden by a raincoat, coat, long skirt, etc.
13. Pedestrians where a part of their body is hidden by any object
14. Pedestrians holding, shouldering or carrying a large package or using an umbrella
15. Pedestrians leaning forward, crouching, lying down or standing still upright
16. Pedestrians pushing a stroller, wheelbarrow, bicycle, etc.

This section is abbreviated and does not include all precautions or limitations. Refer to a Lexus Owner’s Manual for a more comprehensive description of system operation, precautions and limitations.
