Pre-Collision Braking System
30
Ÿ Continued from previous page
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. •
Neither first braking nor secondary braking will operate in the following
cases.
- When your vehicle speed is approximately 1 MPH (1 km/h) or less (When the selector 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 VDC is active
• If the system detects the brake lights of the vehicle in front, your vehicle
will start decelerating earlier than if it does not.
• 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
•Pre-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.
• For information about the braking assist function, refer to the Owner’s
Manual for your vehicle.

Adaptive Cruise Control

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.Continued on next page Ÿ
WARNING
•This system does not provide the driver with an automatic driving function
that handles all traffic conditions.
• 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.
• Set the set vehicle speed within a range that is appropriate to the road con-
ditions and surrounding environment.
• 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”.
• 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
37
- When the vehicle in front isnot directly ahead of your
vehicle and is shifted to
one side
- When there is an obstacle at the side of the road
- When the relative speed difference compared to the
vehicle in front is large
- When a vehicle cuts into your lane in front of you
- When the distance between
vehicles is extremely short
- When your vehicle is drift-ing within the lane
- When driving on a bumpy or unpaved road surface
- When driving on a road with extremely narrow
lanes, such as when traffic
restrictions are in effect or in areas where construction work is taking
place
- When normal driving has become compromised due to an accident or
malfunction
- When extremely heavy cargo is loaded in the cargo area, rear seat or trunk of your vehicle
• There are limits to the capabilities of Adaptive Cruise Control. Even when
the vehicle in front is detected, the system may not be able to decelerate in
time in cases such as when the difference in speeds is large or when the
vehicle in front decelerates suddenly. Operate the brake pedal and decel-
erate as necessary.
• If the buzzer sounds frequently, do not use Adaptive Cruise Control.
• Even when the following distance is short, the “brake more” warning may
not activate in the following cases.
- When the relative speed difference compared to the vehicle in front is small (the two vehicles are travelling at almost the same speed)
- When the vehicle in front is traveling faster than your vehicle (the follow-
ing distance is gradually increasing)
- When another vehicle cuts into your lane very close to your vehicle
- When the vehicle in front decelerated suddenly
- When there are repeated uphill and downhill grades

■Increasing the set vehicle target speed
●
Using the RES/SET switch
While driving with Adaptive Cruise Control on, operate the RES/SET switch as follows.
• Push to the “RES/+” side briefly.
Every time the switch is pushed, the set
vehicle target speed will increase to the
next 5 MPH (5 km/h) increment.
• Push to the “RES/+” side continuously.
While the switch is being pushed, the set
vehicle target speed will increase by 1 MPH
(1 km/h).
When operating the switch, the set vehicle
target speed changes on the meter display
and the multi function display.
●Using the accelerator pedal
Depressing the accelerator pedal will increase vehicle speed. Once the preferred speed has
been attained, push the RES/SET switch to SET/-. When the switch is pressed, the new
vehicle target speed will be set. The new set vehicle speed will be displayed in the EyeSight
display area.
CAUTION
• When Adaptive Cruise Control is operating, the actual vehicle speed is
controlled according to the lead vehicle. Therefore, if the RES/SET switch
is pressed to the “RES/+” and set to a speed higher than the speed of the
lead vehicle, the vehicle will not accelerate - it will maintain a safe following
distance as the first priority. However, because doing so changed the set
vehicle target speed, when the lead vehicle is no longer detected (for
example, if you change to a freeway lane with no vehicles in front), the
vehicle will accelerate to that new set target speed. Change the set vehicle
target speed while briefly checking the value shown in the set speed dis-
play on the EyeSight display.
• When the accelerator pedal is depressed with Adaptive Cruise Control on,
automatic braking control and warnings by Adaptive Cruise Control will not
occur. However, if there is a high risk of collision with an obstacle in front of
the vehicle at this time, the warning and braking control of the Pre-Collision
Braking System may activate.

WARNING
Do not use Adaptive Cruise Control on slippery roads. Doing so may result in
an accident.
CAUTION
When shifting the selector 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
•If 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 80.
•If 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 79.
• 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.
• When the ‘brake more’ function operates,
“Obstacle Detected” will be shown in the
pop-up screen area of the multi information
display, a lead vehicle indicator will flash,
and a buzzer will sound several short
beeps.
• When this function activates, depress the
brake pedal to decelerate and maintain a
correct following distance.
Other functions
WARNING
•If the buzzer sounds frequently, do not use Adaptive Cruise Control.
• The “brake more” warning will not activate in the following situations.
- The accelerator pedal is depressed.
- The brake pedal is depressed.
• 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 travelling 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
• 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.

Pre-Collision Throttle Management
53
Pre-Collision Throttle Management
When an obstacle is detected in front of the
vehicle, and the vehicle is stopped or travel-
ling very slowly, if the system determines that
the accelerator pedal has been depressed by
more than the necessary amount (due to
driver error), it greatly restricts engine output
and ensures that vehicle forward movement is
slower than normal in order to give the driver
additional time to brake or react.
During system operation, a buzzer will sound
several short beeps, and “Obstacle Detected”
will be shown on the pop-up display area of
the multi information display. The lead vehicle
indicator will also flash.
This function only activates when the trans-
mission select lever is in the or posi-
tion.

WARNING
Do not rely excessively on Pre-Collision Throttle Management. Pre-
Collision Throttle Management is not designed to help you avoid
collisions in many situations. Always check the selector lever and pedal
positions as well as the surrounding environment before starting and
operating the vehicle. Relying only on Pre-Collision Throttle
Management could result in an accident.
• Pre-Collision Throttle Management is not designed to maintain the vehicle
in a stopped condition.
• Pre-Collision Throttle Management will not reduce acceleration under all
conditions. It is also not designed to prevent collisions.
• Pre-Collision Throttle Management will operate when an obstacle is
detected in front. However, this function will not reduce acceleration in
cases where no obstacle is recognized (for example when approaching a
cliff, etc.)
• Do not intentionally depress the accelerator pedal excessively when there
are obstacles nearby. If the driver relies only on Pre-Collision Throttle
Management to control acceleration, collisions may occur.
