2017 SUBARU FORESTER warning light

Pre-Collision Braking System
31
When the Pre-Collision Braking System is activated (when the system determines that there
is a high risk of collision with an obstacle in front), if the driver depresses the brake pedal,
the system determines that this is emergency braking and activates braking assist automat-
ically.x
Neither first braking nor secondary braking will operate in the following
cases.
- When the vehicle is traveling at approximately 1 MPH (1 km/h) or less (When the select lever is in the position and your vehicle speed is
approximately 2 MPH (4 km/h) or less) or 100 MPH (160 km/h) or more
- When Vehicle Dynamics Control is active
x If the system detects the brake lights of the vehicle in front, your vehicle
will start decelerating earlier than if it does not.
x There are some cases where the first braking is applied for a longer period
of time. One of the reasons for this is due to a large speed difference with
an obstacle in front. In those cases, stronger or weaker braking control
may be activated.
Pre-Collision Braking Assist operation
CAUTION
If the driver depresses the brake pedal manually while following distance
warning is activated, the Pre-Collision Braking Assist will not work. (The
vehicle decelerates with the normal braking force operated by the driver.)
NOTE
xPre-Collision Braking Assist function does not operate when the vehicle
speed is approximately 7 MPH (10 km/h) or less or 100 MPH (160 km/h) or
more.
x For information about the braking assist function, refer to the Owner’s
Manual for your 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.

WARNING
Do not use Adaptive Cruise Control on slippery roads. Doing so may result in
an accident.
CAUTION
When shifting the select lever to the position, Adaptive Cruise Control will
be automatically canceled. Do not shift the lever to the position unless it is
an emergency. Otherwise the engine brake may not operate, which could
cause an accident.
NOTE
xIf EyeSight operation has temporarily stopped, the Pre-Collision Braking
System OFF indicator light and Lane Departure Warning OFF indicator
light illuminate, and the EyeSight temporary stop indicator is displayed on
the multi information display.
Ÿ Refer to page 89.
xIf EyeSight is malfunctioning, the EyeSight warning indicator is displayed
on the multi information display, and the Pre-Collision Braking System OFF
indicator light and Lane Departure Warning OFF indicator light will also
illuminate. If this occurs, stop the vehicle in a safe location and then turn off
the engine and restart it. If the indicators remain illuminated after restarting
the engine, Adaptive Cruise Control cannot be used. This will not interfere
with ordinary driving; however the system should be inspected by a
SUBARU dealer as soon as possible.
Ÿ Refer to page 88.
x When the operation of Adaptive Cruise Control has been automatically
canceled, perform the set cruise control operation again after the condition
that caused the cancellation has been corrected. If the cruise control func-
tion cannot be set even after the condition has been corrected, EyeSight
may be malfunctioning. This will not interfere with ordinary driving; how-
ever contact a SUBARU dealer and have the system inspected.

■“Brake more” warning
The “brake more” warning is activated while Adaptive Cruise Control is tracking a lead
vehicle. This function warns the driver when it determines that the current level of
deceleration by automatic braking control is insufficient.
x When the ‘brake more’ function operates,
“Obstacle Detected” will be shown in the
warning screen area of the multi information
display, a lead vehicle indicator will flash,
and a buzzer will sound several short
beeps.
x When this function activates, depress the
brake pedal to decelerate and maintain a
correct following distance.
Other functions
WARNING
xIf the buzzer sounds frequently, do not use Adaptive Cruise Control.
x The “brake more” warning will not activate in the following situations.
- The accelerator pedal is depressed.
- The brake pedal is depressed.
x Even when the following distance is short, the “brake more” warning may
not activate in the following situations.
- The difference in speed with the vehicle in front is small. (The two vehi- cles are traveling at almost the same speed.)
- The vehicle in front is traveling faster than your vehicle. (The following
distance is gradually increasing.)
- Another vehicle cuts into your lane very close to your vehicle.
- The vehicle in front decelerates suddenly.
- When there are repeated uphill and downhill grades
x The “brake more” warning may not activate in time in the case of a vehicle that
is stopped at the end of a line at a toll gate, at a stop light or intersection or in
traffic congestion, or a vehicle that is moving much slower than your vehicle.
EyeSight requires a speed differential in order to recognize a potential obsta-
cle and react to it.
