lane assist SUBARU FORESTER 2017 SJ / 4.G Driving Assist Manual

Foreword
Congratulations on choosing a SUBARU vehicle equipped with EyeSightTM.
EyeSight incorporates the latest driver assistance features available from
SUBARU, including such features as Adaptive Cruise Control, a Lead Vehicle Start
Alert and a Lane Departure and Lane Sway Warning, all of which are designed to
assist the driver in making decisions and increase driver comfort and
convenience. Initially, the operation and u se of the various EyeSight features may
be unfamiliar to you. That is why we urge you to read this manual carefully before
using EyeSight. We also recommend that you first take the time to test EyeSight in
order to experience its features for yourself so that you can become familiar with
their operation.
Please keep in mind that it is the responsibilit y of drivers to operate their vehicles
safely at all times. Drivers should always remain alert and should never become
complacent while operating their vehicles because of the presence of EyeSight.
EyeSight is never a substitute for acti ve driver involvement and it may not operate
optimally under all driving conditions.
This booklet is a supplement to the Owner’s Manual for your SUBARU vehicle and
contains a detailed description of EyeSight. It should be read in conjunction with
your Owner’s Manual so that you will gain a thorough understanding of the proper
operation of your vehicle.
The information, specifications and illustrations found in this booklet are those in
effect at the time of printing. FUJI HEAVY INDUSTRIES LTD. reserves the right to
change specificatio ns and designs at any time without prior notice and without
incurring any obligation to make the same or similar changes on vehicles
previously sold.
Please keep this booklet together with your Owner’s Manual and leave it in the
vehicle at the time of resale. The next owner will need the information it contains.

About EyeSight
EyeSight is a driving support system that uses a range of functions to assist the driver in
making decisions in order to provide for more safe and comfortable driving and to reduce
driver fatigue. Making use of images created by stereo cameras specially designed by
SUBARU, EyeSight detects the vehicle in front, obstacles, traffic lanes and other items.
EyeSight
WARNING
Drivers are responsible for driving safely. Always comply with all
traffic rules and regulations regardless of the fact that your vehicle
is equipped with EyeSight. Always maintain a safe following dis-
tance behind the vehicle in front of you, pay attention to your sur-
roundings and the driving conditions, operate the brake pedal and
take other action as necessary in order to maintain a safe following
distance.
Never attempt to drive relying on EyeSight alone.
EyeSight is intended to assist the driver in making decisions in
order to reduce the chance of accidents or damage and lessen the
burden on the driver.
When a warning is activated, pay attention to what is in front of you
and to your surroundings, operate the brake pedal and take other
action as necessary.
This system is not designed to support driving in poor visibility or
in extreme weather conditions, or to protect against careless driv-
ing when the driver is not paying complete attention to the road
ahead. It also cannot prevent collisions from occurring in all driving
conditions.
There are limits to the EyeSight recognition performance and con-
trol performance. Be sure to read the instructions for each function
before using the system, and always use it properly. Improper use
may lead to failure of control performance, which could cause an
accident.
Refer to the following pages for each function:
x For the Pre-Collision Braking System, refer to page 22.
x For Adaptive Cruise Control, refer to page 34.
x For Pre-Collision Throttle Management, refer to page 62.
x For Conventional Cruise Control, refer to page 75.
The EyeSight system in your vehicle is designed for use in
countries in which traffic drives on the right-hand side of the road.
EyeSight for LHD vehicles such as yours is not designed for use in
countries in which vehicles are driven on the left-hand side of the
road.
xThe system may not operate correctly under the conditions listed below.
When these conditions occur, turn off the Pre-Collision Braking System.
Also, do not use Adaptive Cruise Control and Conventional Cruise Control.
- The tire pressure is not correct.
*1
- The temporary spare tire is installed on any wheel.*1

EyeSight includes the following functions.
■Pre-Collision Braking System
This function uses a following distance warning feature to warn the driver to take evasive
action when there is the possibility of a collision with a vehicle or obstacle in front of the
driver’s vehicle. If the driver still does not take evasive action, the brakes are quickly applied
automatically just before the collision in order to reduce the collision damage or, if possible,
prevent the collision.
Ÿ Refer to page 22.
■ Adaptive Cruise Control
This function maintains the set vehicle speed and when there is a vehicle in front in the
same traffic lane, it tracks the speed of the vehicle in front up to the maximum of the set
vehicle speed.
Ÿ Refer to page 34.
■Lane Keep Assist
This function helps suppress lane drifting by detecting lane markings (e.g., white lines) on
highways, etc. and by a ssisting steering operation.
Ÿ Refer to page 54.
■Pre-Collision Throttle Management
This function reduces accidental forward movement caused by the select lever being placed
in the wrong position or the accelerator pedal being accidently depressed, or depressed too
strongly.
Ÿ Refer to page 62.
■Lane Departure Warning
This function warns the driver when the vehicle is about to depart the traffic lane during driv-
ing.
Ÿ Refer to page 68.
■Lane Sway Warning
This system detects vehicle drifting caused by driver fatigue, failure to concentrate on the
road, inattention, strong crosswinds or other factors, and warns the driver.
Ÿ Refer to page 71.

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.
