Pre-Collision Braking System
29
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 or 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 vehi-
cle 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. 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.
- 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 malfunction.
- 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

ŸContinued from previous page
- When the vehicle in front is
not 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
x 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.
x If the buzzer sounds frequently, do not use Adaptive Cruise Control.
x 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 traveling 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

Press the (CRUISE) switch. At this time, “ ” (Adaptive Cruise Control), your vehi-
cle indicator and the “following distance setting” are displayed on the EyeSight display area
in the multi information display.
The set vehicle speed display will read “- - MPH”.
If the switch is pressed once more, the EyeSight display will turn off. It will also automatically
turn off when the engine is stopped.
To set ready status: Adaptive Cruise Control can be set when all
of the following conditions are met and
is displayed on the EyeSight display area.
- All doors (except the rear gate/trunk) are closed.
- The driver’s seatbelt is fastened.
- The electronic parking brake is not engaged (The brake system warning light
is turned off.).
- The select lever is in the position and the paddle shift is not operated.
- The brake pedal is not depressed.
- EyeSight operation is not temporarily stopped.
Ÿ Refer to page 87.
- The road is not a steep slope.

■Increasing the set vehicle target speed
●
Using the RES/SET switch
Push the RES/SET switch in the following
way while you are driving with Adaptive
Cruise Control on: x Push the RES/+ switch towards the position
(1) briefly: the set vehicle speed will
increase in increments of 1 MPH (1 km/h)
every time the button is pushed.
x Push the RES/+ switch towards the position
(1) for longer: the set vehicle speed will
increase in increments of 1 MPH (1 km/h)
while the button is being pushed.
x Push the RES/+ switch towards the position (2) briefly: the set vehicle speed will increase
to the next 5 MPH (5 km/h) increment every time the button is pushed.
x Push the RES/+ switch towards the position (2) for longer: the set vehicle speed will increase
to the next 5 MPH (5 km/h) increment while the button is being pushed and will continue to
advance target speed in 5 MPH (5 km/h) increments as long as the button is pushed.
The set vehicle target speed is shown on the EyeSight display. Using this method, you can
‘fine tune’ the vehicle’s set target speed.
●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
x When Adaptive Cruise Control is operating, the actual vehicle speed is
controlled according to the lead vehicl e. 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.
x 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.

brake.
When parking, always apply brakes manually to come to a full stop, then
set the electronic parking brake.
CAUTION
The stay-stopped function of cruise control will be canceled under the follow-
ing conditions:
x The vehicle is in stay-stopped mode for approximately 2 minutes or more.
(A buzzer will sound 5 intermittent beeps and 1 long beep.)
x Any condition in which automatic cancellation is met. (A buzzer sounds 1
long beep.)
Ÿ Refer to page 49.
After the stay-stopped function has been canceled, the Electronic Parking
Brake will be automatically applied and the electronic parking brake indicator
light will illuminate. However, if any canceling condition for the Electronic
Parking Brake (i.e. the interlock system with the accelerator pedal, switch
operation of the electronic parking brake, etc.) is fulfilled, the Electronic Park-
ing Brake will not work. (For details, refer to the Owner’s Manual for your
vehicle.)
If the accelerator pedal is only slightly depressed while the stay-stopped func-
tion is activated, the stay-stopped function of cruise control may be canceled,
and the Electronic Parking Brake may not work.
