- 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)

• 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.)

• When driving on sharp curves, steep uphill grades or steep downhill
grades
• When driving on a bumpy or unpaved road
• When there are changes in brightness, such as at a tunnel entrance or exit
• Do not test Pre-Collision Braking System on its own. It may operate
improperly and cause an accident.
• The system may not operate correctly under the conditions listed below.
When these conditions occur, turn off the Pre-Collision Braking System.
- The tire pressure is not correct.
*1
- The temporary spare tire is installed on any wheel.*1
- Tires that are worn or have large variations in wear conditions are installed.*1
- Tires other than those of the designated size are installed.*1
- Flat tires have been fixed temporarily with a tire repair kit.
- The suspension has been modified (including a genuine SUBARU sus-
pension that has been modified).
- Any object that disturbs the stereo cameras’ view is installed on the vehi- cle.
- The headlights are dirty or they have snow and ice or dirt on them. (Objects are not correctly illuminated and are difficult to detect.)
- The optical axes are not aligned correctly. (Objects are not correctly illu-
minated and are difficult to detect.)
- The lights including headlights and fog lamps have been modified.
- Vehicle operation has become compromised due to an accident or mal-
function.
- The brake system warning light is illuminated in red.
- A heavy cargo is loaded onto or inside the vehicle.
- The maximum number of occupants is exceeded.
- There is something wrong with the combination meter; such as when the
lights do not illuminate, the beeps do not sound, the display is different
from when it is normal, etc.

CAUTION
•In the following situations, turn off the Pre-Collision Braking System. Other-
wise the Pre-Collision Braking System may activate unexpectedly.
- When the vehicle is being towed
- When loading the vehicle onto a carrier
- When a chassis dynamometer, free-rollers or similar equipment is used
- When a mechanic lifts up the vehicle, starts the engine and spins the wheels freely
- When passing hanging banners, flags or branches, or when thick/tall
vegetation is contacting the vehicle
- When using a drive-through car wash
• The Pre-Collision Braking System may activate in the following situations.
Therefore concentrate on safe driving.
- When passing through an automatic gate (opening and shutting)
- When driving close to the vehicle in front
- When driving in a location where the grade of the road changes rapidly
- 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 passing through clouds of steam or smoke, etc.

- When the exhaust gas emitted by the vehicle in front is clearly visible in cold
weather, etc.
- When there is an obstacle on a curve or intersection
- When narrowly passing a vehicle or an object
- When stopping very close to
a wall or a vehicle in front
• If there is cargo or installed
accessories, etc. that are pro-
truding over the edge of the
front bumper, the vehicle’s
length will increase and the
system may not be able to pre-
vent a collision.
• If the driver operates the brake
pedal during automatic braking, the pedal may feel stiff; however, this is nor-
mal. By depressing the brake pedal further you can apply more braking force.
NOTE
Some unusual noises may be audible during automatic braking. This is
caused by the braking control and is normal.

■Detection of pedestrians
The EyeSight system can also detect
pedestrians. The EyeSight system detects
pedestrians from their size, shape and
movement. The system detects a pedestrian
when the contour of the head and shoulders
are clear.
WARNING
The EyeSight system’s Pre-Collision Braking function also treats pedestrians
as obstacles. However, depending on the conditions, there may be cases
when the system cannot detect a pedestrian. In the following conditions, the
possibility that the system may not be able to detect a pedestrian as an object
is particularly high.
• When pedestrians are walking in a group
• When a pedestrian is next to a wall or other obstacle
• When a pedestrian is using an umbrella
• When a pedestrian is wearing clothes that are a similar color to the sur-
rounding environment
• When a pedestrian is carrying bulky luggage
• When a pedestrian is bent over, crouching down or lying down
• When a pedestrian is in a dark location
• When a pedestrian suddenly crosses in front of you from the side or sud-
denly runs in front of you

Pre-Collision Braking System

When there is an obstacle in the forward direction during driving, the system activates in the
following sequence in order to warn the driver, activate braking control, and active the brake
lights.
Following Distance Warning:
When the system determines that there is a risk of collision, a buzzer sounds repeated short
beeps and the indicators on the multi information display illuminate to warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is not set.
When the driver depresses the brake pedal to decelerate and achieves a suitable following
distance, the warning is canceled.
First Braking and Warning:
When the system determines that there is a high risk of collision with an obstacle in front, a
buzzer sounds repeated short beeps and the indicators on the multi information display illu-
minate to warn the driver, and braking control is activated and the engine output, in some
situations, is also controlled. If the system determines that the amount of evasive action
(braking, steering, etc.) taken by the driver has reduced the risk of collision, braking activa-
tion is canceled.
Secondary Braking and Warning:
If the system then determines that the risk of collision is extremely high, the buzzer changes
to a continuous beeping sound and stronger braking control is activated. If, despite any eva-
sive action taken by the driver, the system subsequently determines that a collision is
unavoidable, braking control and the engine output control are continued.
Even after the vehicle has stopped, depress the brake pedal.
Vehicle restart:
After the vehicle is completely stopped by the automatic braking system, brake will be
slightly released 2 seconds after vehicle stop. After sounding a short tone “beep, beep,
ding”, the vehicle starts creeping.
