PRECAUTIONS: DYNAMIC RADAR CRUISE CONTROL

PRECAUTIONS: DYNAMIC RADAR CRUISE CONTROL

Dynamic Radar Cruise Control(9) is a system primarily for driving on expressways and highways. With regard to traffic conditions on general roads, there are cases where it will not operate appropriately and could lead to an accident. In these situations, do not use Dynamic Radar Cruise Control. Dynamic Radar Cruise Control (9) operation is dependent on the millimeter-wave radar’s ability to detect a preceding vehicle, as well as the detectability of the preceding vehicle itself. While driving, the driver will need to continually pay attention to the distance between vehicles with the leading vehicle and surroundings, and decelerate and accelerate themselves to ensure the distance between their vehicle and preceding or following vehicles is safe. Situations such as a broken, dirty, ice, rain, snow, film, or sticker-covered front Lexus emblem blocking the radar, all may affect Dynamic Radar Cruise Control (9) operation.

IN THE FOLLOWING CONDITIONS, DYNAMIC RADAR CRUISE CONTROL (9) MAY LEAD TO AN UNEXPECTED ACCIDENT, SO DO NOT USE THE SYSTEM:

1. Bad weather conditions, such as rain, fog, snow or a dust storm
• When the system judges the weather to be bad, there are cases where it automatically turns OFF

2. Raindrops, snow, ice, road debris, or film/metal coatings on the millimeter-wave radar sensor (badge or cover)

• If the system detects filth, it may automatically turn OFF

Other:

• Roads with a lot of traffic or around a sharp curve
• Slippery road surfaces, such as icy or snowy roads
• Steep Inclines
• Traffic conditions leading to frequent acceleration and deceleration
• When leaving lane while on an expressway, etc.
• When the vehicle is being towed

IN THE FOLLOWING CONDITIONS, THE SYSTEM IS NOT ABLE TO ACCURATELY DETECT LEADING VEHICLES AND MAY NOT BE ABLE TO MAINTAIN APPROPRIATE DISTANCE BETWEEN VEHICLES:

1. When the leading vehicle is pulling an empty trailer, etc., making rear surface area very small (including motorcycles)
2. When vehicle angle or stance changes dramatically due to load, changes to suspension, tire pressure, etc.

IN THE FOLLOWING CONDITIONS, DETECTION OF THE LEADING VEHICLE MAY BE DELAYED OR MAY NOT BE POSSIBLE:

• When a leading vehicle cuts in front of your vehicle at a close distance
• Motorcycle driving at the edge of the lane

IN THE FOLLOWING CONDITIONS, THE SYSTEM MAY INADVERTENTLY OPERATE OR MAY NOT BE ABLE TO DETECT THE LEADING VEHICLE:

1. In a curve or when the lane width is narrow; if a vehicle from another lane is recognized as that of your lane
2. When the leading vehicle is driving at the edge of the lane and is not in the detection area

Other:

• When the leading vehicle leaves the sensor detection area, such as at a curve
• When the leading vehicle leaves the sensor detection area due to steering input

THE SYSTEM WILL NOT OPERATE IN THE FOLLOWING CONDITION:

• If the opposing object is a stopped vehicle or a leading vehicle with a speed dramatically slow compared to your own vehicle
