EyeSight does not restart after a temporary stop.
Is the X-mode turned on?
EyeSight cannot be activated when the X-mode is turned on.
Are you driving in the rain with old 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.
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.
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.
