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)
S01970
Low objects surrounding the vehicle
cannot be detected.

xDo not install any accessories other than the ones designated by SUBARU
on the prohibited areas shown in the illustrations (grey zones).
Even if some accessories are installed on the outside of the prohibited areas,
abnormal operation of EyeSight may occur due to the reflection of the light or
any objects. In this situation, move the accessories. For details, contact a
SUBARU dealer.

x Do not place any objects on top of the instrument panel. The stereo cameras
may not be able to detect objects accurately and the EyeSight system may
not function properly due to reflections in the front windshield. For details,
contact a SUBARU dealer.
x If the top of the instrument panel is polished with chemicals or other sub-
stances, the stereo cameras may not be able to detect objects accurately
and the EyeSight system may not operate properly due to reflections in the
front windshield.
x Do not install any wiper blades other than genuine SUBARU wiper blades.
Doing so may affect the stereo cameras’ field of vision and could prevent the
EyeSight system from functioning properly.
x Replace damaged wiper blades as soon as possible. The stereo cameras
may not be able to detect objects accurately and the EyeSight system may
not function properly due to liquid remaining on the windshield.
x Do not install any accessories
on the front side such as on
the hood or the grille. It may
affect the camera view and
the system may not operate
correctly.
x Make sure that the cargo
loaded on the roof does not
obstruct or interfere in the ste-
reo cameras’ field of view.
Obstructing the stereo cam-
eras’ view may impair the sys-
tem operation. For details,
contact a SUBARU dealer.

Continued on next page Ÿ
- When the detected object is something other than a vehicle, motorcycle,
bicycle or pedestrian• A domestic animal or other animal (a dog or deer, etc.)
• A guardrail, telephone pole, tree, fence or wall, etc.
- Even if the obstacle is a motorcycle, bicycle or pedestrian, depending on
the brightness of the surroundings as well as the relative movement, and
aspect or angle of the object, there may be cases when the system can-
not detect it.
- When the system determines that operation by the driver (based on accelerator pedal operation, braking, steering wheel angle, etc.) is
intended as evasive action
- Vehicle maintenance status (brake systems, tire wear, tire pressure, whether a temporary spare tire is being used, etc.)
- When towing a trailer or another vehicle, etc.
- When the brakes are cold due to outside temperature being low or just after starting the engine.
- When the brakes are overheated on downhill grades (braking effective- ness is reduced)
- When driving in rain or after washing the vehicle (the brakes are wet and
braking effectiveness is reduced)
- Recognition conditions of the stereo cameras In particular, the function may be unable to stop the vehicle or may not
activate in the following cases.
• Bad weather (for example heavy rain, a blizzard or thick fog)
• 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,
dust or other substances to obscure the view through the windshield
• When driving at night or in a tunnel without the headlights on
• When driving at night or in a tunnel when there is a vehicle in front that does not have its taillights on
• When approaching a motorcycle, bicycle or pedestrian at night
• When ambient light is poor in the evening or early morning
• When a vehicle, motorcycle, bicycle or pedestrian is outside the area illuminated by the headlights
• When affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight beams, etc.)
• When there is snow, frost, dirt or dust on the windshield or it is clouded
• When fluid has not been fully wiped off the windshield during or after washer use
• When the target cannot be correctly recognized because the stereo cameras’ view is obstructed by water droplets from rain or the window
washer, or by the wiper blades.
• When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle)

Adaptive Cruise Control
36
ŸContinued from previous page
- When water droplets from rain or the window washer, or dirt has not
been fully wiped off the windshield
It may not be possible to detect the vehicle in front, making correct
control impossible.
- When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle)
x The stereo cameras may have difficulty detecting the following objects or
conditions. Operate the brake pedal and take other actions as necessary.
- Vehicles at significantly different speeds (vehicles driving slowly, stopped or oncoming vehicles, etc.)
- Vehicles cutting into your lane
- Motorcycles, bicycles, pedestrians and animals, etc.
- When light is poor in the evening or early morning
- When driving at night or in a tunnel without the headlights on
- When driving at night or in a tunnel when there is a vehicle in front that does not have its taillights on
- When affected by strong light from the front (sunlight or headlight high beams, etc.)
- Vehicles in front that have a rear aspect that is low,
small or irregular (the sys-
tem may recognize
another part of the vehicle
and will determine opera-
tion from that)• An empty truck or trailer that has no cargo in the
cargo bed being affected
by wind
• Vehicles that have cargo protruding from their
back ends
• Non-standard shaped ve- hicles (vehicle transport-
ers or vehicles with a sidecar fitted, etc.)
• Vehicles that are low
- Objects that are located close to the bumper of your vehicle
x When you do not want to use Adaptive Cruise Control, be sure to turn the
(CRUISE) switch off. If the switch is left on, cruise control may be
accidentally engaged, possibly resulting in an accident.
x Before using Adaptive Cruise Control, be sure to fully verify the safety of
the vehicle occupants and the area around the vehicle. Never operate the
cruise control from outside the vehicle.

ŸContinued from previous page
- Frozen roads, snow-covered roads or other slippery road surfacesThe tires may spin, causing loss of control of the vehicle.
- When entering a sharp curve into an interchange or junction, or a service area, parking area, toll booth or other facilities.
- When there are changes in brightness, such as at a tunnel entrance or exit.
- When visibility is poor due to sand, smoke or water vapor blowing in the wind, or when the vehicle in front or oncoming traffic causes water,
snow, dirt or dust to obscure the view.
- When there is snow, frost, dirt or dust on the windshield or it is clouded.
- When water droplets from rain or dirt have not been fully wiped off on the windshield.
It may not be possible to detect the lane, making correct control impossi-
ble.
- When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle).
x The stereo cameras may have difficulty detecting the objects under the follow-
ing conditions and the system may not operate properly.
- When driving at night or in a tunnel without the headlights on.
- When light is poor in the evening or early morning.
- In bad weather (for example, rain or snow)
- The distance between your vehicle and the vehicle in front is short, mak- ing it difficult to detect lane markings.
- When a vehicle intruded from an adjacent lane or the vehicle in front changed lanes.
- The shape of a curve in the road suddenly changes.
- Shadows of guardrails or similar objects are overlapped on the lane markings.
- When your vehicle is exposed to a strong light from the front (backlight from the sun, headlights, etc.).
- The width of a lane is narrow.
- The stereo cameras may have difficulty detecting the lane due to the per- formance of the cameras.
• There are no lane markings or they are very worn.
• The lane markings are painted in yellow.
• It is difficult to detect lane markings because they are similar in color to the road surface.
• The lane markings are drawn in double.
• The width of lane markings is narrow.
• The indicated lines for the area are touched to walls and poles.
- The shape of lane markings suddenly changes (entrance/exit of a curve, crank and S-shaped road, etc.).

- The brightness changes such as when you drive under an overpass.

Pre-Collision Throttle Management
63
Continued on next page Ÿ
x
If your vehicle is trapped on a railroad crossing and you are trying to
escape by driving through the crossing gate, the stereo cameras may rec-
ognize the crossing gate as an obstacle and Pre-Collision Throttle
Management system may activate. In this case, remain calm and either
continue to depress the accelerator pedal or turn off the Pre-Collision
Throttle Management system.
Ÿ Refer to page 67.
x Pre-Collision Throttle Management may not activate depending on the fol-
lowing conditions:
- The distance between your vehicle and the obstacle, speed difference, and lateral displacement (amount of offset)
- Recognition status of the stereo cameras
In particular, the function may not activate in the following cases:• Bad weather (for example heavy rain, a blizzard or thick fog)
• When visibility is poor due to sand or smoke in the air
• When light is poor in the evening, early morning, or at night
• In a dark area (indoor parking area, etc.)
• When there is an obstacle outside the area illuminated by the head-
lights
• When affected by strong light from the front (for example sunlight at sunrise or sunset headlight beams, etc.)
• When there is snow, frost, dirt or dust on the windshield, or it is clouded
• When fluid has not been fully wiped off the windshield during or after use of the window washer
• When obstacles cannot be correctly recognized due to water droplets from rain or the washer, or the wiper blades obstructing the stereo cam-
eras’ field of view
• When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle)
• With low obstacles (low wall, crash barrier, low vehicle, etc.)
• When the size and height of an obstacle is smaller than the limitations of the stereo cameras’ recognition capability
• With small animals or children.
• With pedestrians who are sitting or lying down
• When the rear portion
nearest your vehicle is
too small or too close
(such as a trailer or
oncoming vehicle) the
system may not recog-
nize the part of that
vehicle which is closest
to you.
