CAUTION
xThe characteristics of the stereo cameras are similar to those of human
eyes. For this reason, conditions that make it difficult for the driver to see
in the forward direction have the same effect on the stereo cameras and
make it difficult for the system to detect vehicles, obstacles and traffic
lanes.
x Detection by the EyeSight system is limited to objects that are within the
range of the stereo cameras’ field of vision. Also, after an object enters the
range of the cameras’ field of vision, it may take some time for the system
to detect it as a controllable target and warn the driver.
x Under the conditions listed below, it will become more difficult for the sys-
tem to detect the vehicle in front, motorcycles, bicycles, pedestrians and
obstacles on the road, and lane markers. Also, EyeSight may temporarily
stop operating. However, the temporary stop will be canceled once these
conditions have improved and the vehicle is driven for a short period of
time.
- Bad weather (for example heavy rain, a blizzard or thick fog). In particu- lar, the system is more likely to temporarily stop operating when there is
an oil film adhering to the windshield, a glass coating has been applied
or old wipers are used.)
- When affected by strong light from the front (sunlight or headlight beams of oncoming traffic, etc.)
- When the front windshield washer is being used.
- The windshield has become fogged, or snow, dirt, dust or frost has adhered to it, reducing the stereo cameras’ field of view.
- The vehicle is tilted at an extreme angle due to loaded cargo or other factors.
- When visibility is poor due to sand, smoke or water vapor in the air, or when the vehicle in front or oncoming traffic causes water, snow, dirt or
other substances to obscure the view
- When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle)

The stereo cameras are installed at the posi-
tions of the front map lights.

Handling of the Stereo Cameras
CAUTION
xA function is included that will automatic ally detect that the fronts of the
stereo cameras are dirty. However it is not 100% effective.
Under certain conditions, this function may fail to detect that the fronts of
the stereo cameras have become dirty. In addition, this function may not
detect that there is snow or ice on the windshield close to the stereo cam-
eras. In such conditions, be sure to keep the windshield clean at all times
(indicated by ). Otherwise the system may not operate correctly.
When this function detects that the fronts of the stereo cameras are dirty,
no EyeSight functions are activated except for Conventional Cruise
Control.
x The stereo camera is a precision component. Always observe the following
precautions especially when handling lenses.
- Never touch the stereo camera lenses, and do not attempt to wipe or
clean the lenses. Doing so could damage or soil the lens, and lead to
improper system performance.
If you ever touch a lens for any reason, be sure to contact a SUBARU
dealer.

xKeep the windshield (outside and inside) clean at all times. When the wind-
shield has become fogged, or it has a dirt or an oil film on it, the stereo
camera may not detect objects accurately and the EyeSight system may
not operate correctly. Never mount any device to the center air vent, as
any airflow change may impact performance of the EyeSight system.
x Do not place any stickers or accessories on the windshield (outside or
inside). If you have to do so (for example, legally required or electronic toll
tag), avoid the area directly in front of the camera. Doing so may adversely
affect the field of vision of the stereo camera and can cause improper
operation of the system. For details, contact a SUBARU dealer.
x Do not use any glass coating agents or similar substances on the wind-
shield. Doing so may prevent the system from operating correctly.
x Do not install a film on the front windshield. The system may not operate
correctly.
x If there are scratches or cracks on the front windshield, contact a SUBARU
dealer.
x To have the front windshield replaced or repaired, contact a SUBARU
dealer. Do not install a front windshield other than a genuine SUBARU
front windshield. The stereo cameras may not be able to detect objects
accurately and the EyeSight system may not operate properly.

Troubleshooting
98
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 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.
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.
