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 view. Also, after an object enters the
range of the cameras’ field of view, 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)

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.

- 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.
xBad weather (for example heavy rain, a blizzard or thick fog)
x 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
x When driving at night or in a tunnel without the headlights on
x When driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
x When approaching a motorcycle, bicycle or pedestrian at night
x When ambient light is poor in the evening or early morning
x When a vehicle, motorcycle, bicycle or pedestrian is outside the area
illuminated by the headlights
x When affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight beams, etc.)
x When there is snow, frost, dirt or dust on the windshield or it is clouded
x When fluid has not been fully wiped off the windshield during or after
washer use
x 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.

Pre-Collision Braking System

xWhen you suddenly change lanes and your vehicle is immediately
behind an obstacle
x When there is a vehicle, motorcycle, bicycle or pedestrian in a location
close to your vehicle’s bumper
x When the speed difference between your vehicle and an obstacle is 4
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 view.)
x When driving on sharp curves, steep uphill grades or steep downhill
grades
x When driving on a bumpy or unpaved road
x When there are changes in brightness, such as at a tunnel entrance or
exit

Adaptive Cruise Control
Adaptive Cruise Control is a driving support system intended to allow more comfortable driving on
expressways, freeways and interstate highways. The vehicle in front in the same traffic lane is
detected by means of the stereo cameras, and your vehicle tracks the vehicle in front (up to the
maximum speed of the set vehicle speed) while automatically maintaining a following distance that
corresponds to the speed of the vehicle in front. Through operation of the electronic parking brake,
the system uses the vehicle’s conventional braking system to stop your vehicle when the vehicle
in front is stopped. The vehicle is capable of being controlled at a speed between approximately 0
and 90 MPH (145 km/h). Please remember that you should not exceed posted speed limits.
WARNING
xThis system does not provide the driver with an automatic driving function
that handles all traffic conditions.
x Do not rely excessively on Adaptive Cruise Control. This system is not intended
to assist in driving when the driver is not paying full attention to what is ahead of
him/her due to distractions or a lack of concentration while driving, or under
conditions of poor visibility. It is not intended to prevent rear-end collisions.
Strive for safe driving at all times. Always maintain a safe following distance
behind the vehicle in front of you, pay attention to your surroundings and the
driving conditions, and operate the brake pedal and take other action as neces-
sary.
x Set the set vehicle speed within a range that is appropriate to the road con-
ditions and surrounding environment.
x Before using the system, perform a daily inspection and verify that there
are no malfunctions of the tires or brakes.
Ÿ Refer to the separate “Warranty and Maintenance Booklet”.
x The system may not operate correctly under the conditions listed below.
When these conditions occur, do not use Adaptive Cruise Control.
- The tire pressure is not correct.
*1
- The temporary spare tire is installed.*1
- Tires that are unevenly worn or tires with uneven wear patterns are installed.*1
- Tires that are the wrong 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 vehicle.

Adaptive Cruise Control
37
CAUTION
xAfter 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.
x There is no possibility that the vehicle will automatically begin moving from
a stay-stopped condition without operation from the driver.
x If the conditions for automatically canceling cruise control (
Ÿ refer to page
49) are met while the vehicle is stay-stopped, Adaptive Cruise Control is
canceled and for safety reasons, the electronic parking brake is automati-
cally applied.
x 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.

Lane Keep Assist
The stereo cameras detect lane markings
(including Botts’ dots) of the lane and the sys-
tem assists the steering operation by working
with the electric power steering to help keep
your vehicle in its lane when driving on
expressways, freeways and interstate high-
ways.
WARNING
Lane Keep Assist is not an automatic driving system.
Do not overestimate the capabilities of Lane Keep Assist. It is not a sys-
tem to assist inattentive driving or meant to permit driving without hold-
ing the steering wheel. Make sure to grip the steering wheel while
driving. To drive safely, check the distance from the vehicle in front or
from a vehicle driving in parallel with your vehicle, the surrounding con-
ditions and the surrounding environment while driving.
If you feel that the level of control and timing by the system are different from
your own driving style, the system may not support safe driving. Do not use
Lane Keep Assist.
Lane Keep Assist does not always operate under all situations. If you rely
only on the Lane Keep Assist to stay in a lane, it may cause an accident such
as a collision with an obstacle beside your lane or with a vehicle driving in an
adjacent lane.x Check that there are no problems with the tires and brakes during a daily
inspection before using the system.
Ÿ Refer to “Warranty and Maintenance Booklet”.
x The system may not operate properly under the following conditions. Do
not use Lane Keep Assist.
- The air pressure of tires is not to specification.
*1
- Tires that are unevenly worn or tires with uneven wear patterns are installed.*1
- Tires that are the wrong size are installed.*1
- The wheel balance is abnormal (e.g., the balance weight is removed ormisaligned.)*1
- The wheel alignment is out of the specified value.*1
- Flat tires have been fixed temporarily with a tire repair kit.
- The suspension has been modified (including genuine SUBARU parts).
