- When passing through the entrance or exit of a tunnel
- When the rear aspect of the vehicle in front is low, small or irregular (forexample a low bed trailer, etc.)
- When there is a fence, a wall or a shutter, etc. with a uniform pattern (a
striped pattern, brick, etc.) or with no pattern in front
- When there is a wall or door made of glass or a mirror in front
- When driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
- When passing a banner or flag, low branches on a tree or thick/tall vege- tation
- On steep uphill or downhill grades
- When the stereo cameras are obstructed by a hand, etc. (If even one of the cameras is obstructed, the system does not operate properly.)
- When it is completely dark and no objects are detected
- When the area around the vehicle has a uniform color (such as when completely covered in snow, etc.)
- When the stereo camera lenses are dirty due to fingerprints, etc.
- When accurate detection is not possible due to reflections in the front windshield
- When the stereo cameras have become misaligned due to a strong impact
• Under the conditions listed below, EyeSight may temporarily stop
operating. If this occurs, EyeSight will resume operating when the
conditions improve.
- The temperature inside the vehicle is high, such as after the vehicle was left in bright sunshine, or the temperature inside the vehicle is low, such
as after the vehicle was left in an extremely cold environment.
- Immediately after the engine starts
• When there is a malfunction in the EyeSight system, turn off the Pre-Colli-
sion Braking System (
Ÿ refer to page 31) and the Lane Departure Warning
(
Ÿ refer to page 61), and stop using the Adaptive Cruise Control and Con-
ventional Cruise Control. Contact a SUBARU dealer and have the system
inspected.
• When the Vehicle Dynamics Control warning light is illuminated, the Pre-
Collision Braking System may not operate properly. In this case, turn off
the Pre-Collision Braking System. Also, do not use the Adaptive Cruise
Control or Conventional Cruise Control.

Pre-Collision Braking System
22
Ÿ Continued from previous page
- 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)

Pre-Collision Braking System
23
Continued on next page Ÿ
• When the rear aspect of
the vehicle in front is
low, small or irregular
(the system may recog-
nize another part of the
vehicle as its rear and
will determine operation
from that)- When there is an
empty truck or trailer
with no rear and/or
side panels on the
cargo bed
- With vehicles that have cargo protruding
from their back ends
- With non-standard shaped vehicles (vehicle transporters or vehicles with a sidecar fitted, etc.)
- When the height of the vehicle is low, etc.
• When there is a wall, etc. in front of a stopped vehicle
• When there is another object near the vehicle
• When a vehicle, etc. has it’s side facing you.
• With vehicles that are backing up or with oncoming vehicles, 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, etc.
- With pedestrians who are sitting or lying down
• When the detected object
is a fence or wall, etc.
with a uniform pattern (a
striped pattern or brick
pattern, etc.)
• When there is a wall ordoor made of glass or a
mirror in front
• When the vehicle in front suddenly swerves, accel-
erates, or decelerates.
• When a vehicle, motorcy- cle, bicycle or pedestrian
suddenly cuts in from the
side or suddenly runs in
front of you.
• When you suddenly change lanes and your vehicle is immediately
behind an obstacle
• When there is a vehicle, motorcycle, bicycle or pedestrian in a location
close to your vehicle’s bumper
• When the speed difference between your vehicle and an obstacle is 5 MPH (5 km/h) or less (As braking is performed once the obstacle is in
close proximity to your vehicle, depending on the shape and size of the
obstacle, there may be some cases when the obstacle is outside the
range of the cameras’ field of vision.)

Adaptive Cruise Control
35
Continued on next page Ÿ
- 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)
• 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
• 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.
• 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.
S02133

Adaptive Cruise Control
38
CAUTION
•After Adaptive Cruise Control has started, it maintains control continuously
according to the behavior of the vehicle in front. When your vehicle comes
to a stop if the vehicle in front has stopped, the stay-stopped function is
engaged. However, if the EyeSight stereo cameras lost detection of the
vehicle in front, the system may not stop your vehicle. Operate the brake
pedal and maintain the correct following distance as necessary. Be aware
that the EyeSight system has difficulty detecting objects or vehicles that
have a relative speed in comparison to your vehicle. Therefore, if the
EyeSight system loses detection just as you are approaching a line of
stopped cars, for example - you will have to brake manually.
• There is no possibility that the vehicle will automatically begin moving from
a stay-stopped condition without operation from the driver.
• Braking may not be sufficient depending on the following conditions. Oper-
ate the brake pedal and decelerate as necessary.
- Vehicle conditions (amount of load, number of occupants, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- Vehicle maintenance status (brake systems, tire wear, air pressure, tem- porary spare tire is being used, etc.)
- When the brakes are cold. (For example, just after the engine is started or when the outside temperature is low.)
- For a short period of time when driving after the engine is started until the engine has warmed-up
- When the brakes are overheated on downhill grades (braking effective-
ness may be reduced)
- When driving in rain or after washing the vehicle (the brakes may become wet and braking effectiveness may be reduced)
- When towing a trailer or another vehicle, etc.

Pre-Collision Throttle Management
54
Ÿ Continued from previous page
• 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 58.
• 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.
