A vehicle (in front of your vehicle) is not detected, is detected later or detection is
lost quickly.
Is the vehicle in front stopped, moving slowly relative to your vehicle or moving
extremely slowly?
Detection of stopped vehicles, vehicle moving slowly relative to your vehicle, and
vehicles moving extremely slowly may be difficult.
Is the windshield dirty or fogged?
If the windshield is dirty or fogged, it may not be possible to detect object or vehi-
cles. Clean off the dirt or fog from the windshield, and then try using the system
again.
Is the vehicle in front far away?
The maximum detection distance of EyeSight’s stereo cameras is approximately
360 ft (110 m). Detection is not possible if the vehicle is farther away.
Is the vehicle on a curve?
The detection range is limited in the left and right directions when the cameras are
properly aimed.
Is the vehicle on a road with repeated uphill and downhill grades (such as an over-
pass), or on a banked road?
The detection range is limited in the up and down directions.
Did the vehicle detected in front change?
Detection may be delayed after the vehicle in front has changed.
Have water, snow or other substances been kicked up by the vehicle in front as it
drives?
When water or snow have been kicked up, it may not be possible to detect the
vehicle in front.
Control is activated even though no vehicle in front is detected?
Is there a vehicle in the neighboring lane?
Depending on the road conditions, vehicles in neighboring lanes may be detected
as well as a vehicle directly in front.
Are you driving on or near a curve?
When driving on a curve, braking control may be activated in response to guard
rails, the angle of the steering wheel, or roadside structures.
The Lead Vehicle Start Alert activates, even though there is no vehicle in front.
Depending on surrounding objects, traffic environment and weather, the Lead
Vehicle Start Alert may issue a warning in response to objects other than a vehicle
that appear in front of your vehicle.

Troubleshooting

EyeSight does not restart after a temporary stop.
Has the vehicle been parked in a cold or hot place? In either of these cases,
EyeSight may temporarily stop operating until the temperature increases or
decreases to a temperature at which the camera is operable.
Are you driving in the rain with poorly performing wipers or is there an oily film on
the windshield?
Replace the wipers with new ones, or clean the oily film off the windshield.
Are you driving in poor weather conditions with heavy rain, snow, fog, or dust? In
these cases, EyeSight may temporarily stop operating while visibility is very low.
Is your vehicle subject to sunlight from the front (sunset or sunrise, etc.) or to
bright headlights from oncoming vehicles at nighttime?
In these cases, EyeSight may temporarily stop operating.
The timing of the “brake more” warning is sometimes earlier and sometimes later
than what seems to be normal operation.
The “brake more” warning sounds when the system determines that more braking
is necessary, based on conditions such as the distance from the vehicle in front
and the difference in speed compared to it. As a result, timing may vary depend-
ing on how the brakes are applied in relation to the vehicle in front, and your rela-
tive speed to that vehicle.
When the vehicle in front has turned off the road away or the distance from the
vehicle in front has increased, acceleration is sometimes slower or faster.
Depending on the timing of when the detection of the vehicle in front is lost,
EyeSight’s ability to react may be slower, causing the start of acceleration to feel
delayed and braking time to feel longer than what seems to be normal operation.
