radar sensor and front camera, prevent-

ing the system from operating properly:

• When a detectable object is approaching 

your vehicle

• When your vehicle or a detectable object 

is wobbling

• If a detectable object makes an abrupt 

maneuver (such as sudden swerving, 

acceleration or deceleration)

• When your vehicle approaches a detect-

able object rapidly

• When a detectable object is not directly 

in front of your vehicle

• When a detectable object is near a wall, 

fence, guardrail, manhole cover, vehicle, 

steel plate on the road, etc.

• When a detectable object is under a 

structure

• When  part  of  a  detectable object is hid-

den by an object, such as large baggage, 

an umbrella, or guardrail

• When there are many things which can 

reflect the radio waves of the radar in the 

vicinity (tunnels, truss bridges, gravel 

roads, snow covered road that have 

tracks, etc.)

• When there is an effect on the radio 

waves to the radar that is installed on 

another vehicle

• When multiple detectable objects are 

close together

• If the sun or other light is shining directly 

on a detectable object

• When a detectable object is a shade of 

white and looks extremely bright

• When a detectable object appears to be 

nearly the same color or brightness as its 

surroundings

• If a detectable object cuts or suddenly 

emerges in front of your vehicle

• When the front of your vehicle is hit by 

water, snow, dust, etc.

• When a very bright light ahead, such as 

the sun or the headlights of oncoming 

traffic, shines directly into the front cam-

era

• When approaching the side or front of a 

vehicle ahead

• If a vehicle ahead is a motorcycle

• If a vehicle ahead is narrow, such as a per-

sonal mobility vehicle

• If a preceding vehicle has a small rear 

end, such as an unloaded truck

• If a preceding vehicle has a low rear end, 

such as a low bed trailer

• If a vehicle ahead has extremely high 

ground clearance

• If a vehicle ahead is carrying a load which 

protrudes past its rear bumper

• If a vehicle ahead is irregularly shaped, 

such as a tractor or side car

• If a vehicle ahead is a child sized bicycle, 

a bicycle that is carrying a large load, a 

bicycle ridden by more than one person, 

or a uniquely shaped bicycle (bicycle with 

a child seat, tandem bicycle, etc.)

• If a pedestrian/or the riding height of a 

bicyclist ahead is shorter than approxi-

mately 3.2 ft. (1 m) or taller than approxi-

mately 6.5 ft. (2 m)

• If a pedestrian/bicyclist is wearing over-

sized clothing (a rain coat, long skirt, 

etc.), making their silhouette obscure

• If a pedestrian is bending forward or 

squatting or bicyclist is bending forward

• If a pedestrian/bicyclist is moving fast

• If a pedestrian is pushing a stroller, wheel-

chair, bicycle or other vehicle

• When driving in inclement weather such
