Pre-Collision Braking System
23
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
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. 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
x This 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 pre-
vent rear-end collisions.
Strive for safe driving at all times. Always maintain a safe following dis-
tance 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 necessary.
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 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.
*2
*1: The wheels and tires have functions that are critically important. Be sure to use the correct ones. For details, refer to the Owner’s Manual
for your vehicle.
*2: For details about the combination meter, refer to the Owner’s Manual for your vehicle.

Adaptive Cruise Control
39
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 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
system 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
highways.
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 problems with the tires and brakes during a daily
inspection before using the system.
* 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 worn or have large variations in wear conditions are installed.*1
- Tires other than those of the designated size are installed.*1
- The wheel balance is abnormal (e.g., the balance weight is removed ormisaligned.)*1
- The wheel alignment is not adjusted within the specified value.*1
- Flat tires have been fixed temporarily with a tire repair kit.
- The suspension has been modified (including genuine SUBARU parts).
- Any object that disturbs the stereo cameras’ view is installed on the vehi-cle.
