Troubleshooting
EyeSight does not restart after a temporary stop.
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 poor.
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.
Are you parking in an extremely hot or cold condition?
EyeSight will maintain temporary stop until the temperature is back to normal.
The timing of the "Obstacle Detected" warning is sometimes earlier and some-
times later than what seems to be normal operation.
The "Obstacle Detected" 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
depending on how the brakes are applied in relation to the vehicle in front, and
your relative speed to that vehicle.
When the vehicle in front has turned off the roadway or the distance from the vehi-
cle 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.
