xAdaptive Cruise Control is designed for use on expressways, freeways, toll
roads, interstate highways and similar limited access roads. It is not intended
to be used in city traffic. In the following conditions, do not use Adaptive
Cruise Control. Doing so may result in an accident.
- Ordinary roads (roads other than those mentioned above) Depending on the driving environment (complexity of roads and other fac-
tors), the system may not be able to perform as the traffic conditions
require, and that may result in an accident.
- Roads with sharp curves or winding roads
- Frozen roads, snow-covered roads or other slippery road surfaces
- The tires may spin, causing loss of control of the vehicle.
- Traffic conditions when frequent acceleration and deceleration make it diffi- cult to maintain the following distance
It may not be possible for the system to perform as the traffic conditions
require.
- Steep downhill grades The set vehicle speed may be exceeded.
- On a steep continuous downhill grade The brakes may overheat.
- Roads and overpasses with repeated steep uphill and downhill grades Detection of the vehicle in front may be lost, or the road surface may be
detected instead of the vehicle in front, making correct control impossible.
- When entering a sharp curve into an interchange or junction, or a service area, parking area, toll booth or other facilities
Detection of the vehicle in front may not be possible.
- When there are changes in brightness, such as at a tunnel entrance or exit
- When visibility is poor due to sand, smoke or water vapor blowing in the wind, or when the vehicle in front or oncoming traffic causes water, snow,
dirt or dust to obscure the view
Detection of the vehicle in front may be lost, or water or other substances
may be incorrectly detected instead, making correct control impossible.
- When there is snow, frost, dirt or dust on the windshield or it is clouded

- Frozen roads, snow-covered roads or other slippery road surfaces
The tires may spin, causing loss of control of the vehicle.
- When entering a sharp curve into an interchange or junction, or a service area, parking area, toll booth or other facilities.
- When there are changes in brightness, such as at a tunnel entrance or exit.
- When visibility is poor due to sand, smoke or water vapor blowing in the wind, or when the vehicle in front or oncoming traffic causes water,
snow, dirt or dust to obscure the view.
- When there is snow, frost, dirt or dust on the windshield or it is clouded.
- When water droplets from rain or dirt have not been fully wiped off on the windshield.
It may not be possible to detect the lane, making correct control impossi-
ble.
- When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle).
- The stereo cameras may have difficulty detecting the objects under the following conditions and the system may not operate properly.
- When driving at night or in a tunnel without the headlights on.
- When light is poor in the evening or early morning.
- In bad weather (for example, rain or snow)
- The distance between your vehicle and the vehicle in front is short, mak- ing it difficult to detect lane markings.
- When a vehicle intruded from an adjacent lane or the vehicle in front changed lanes.
- The shape of a curve in the road suddenly changes.
- Shadows of guardrails or similar objects are overlapped on the lane markings.
- When your vehicle is exposed to a strong light from the front (backlight from the sun, headlights, etc.).
- The width of a lane is narrow.
- The stereo cameras may have difficulty detecting the lane due to the per- formance of the cameras.
xThere are no lane markings or they are very worn.
x The lane markings are painted in yellow.
x It is difficult to detect lane markings because they are similar in color to
the road surface.
x The lane markings are drawn in double.
x The width of lane markings is narrow.
x The indicated lines for the area are touched to walls and poles.
- The shape of lane markings suddenly changes (entrance/exit of a curve, crank and S-shaped road, etc.).
- There is curb or side wall in the road shoulder.
- The brightness changes such as when you drive under an overpass.
