Adaptive Cruise Control
38
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

Adaptive Cruise Control

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.

Adaptive Cruise Control is available when the engine is turned on.
■Setting Adaptive Cruise Control
(1) Setting Adaptive Cruise Control to standby status
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 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 89.
- The road is not a steep slope.
- The steering wheel has not been turned significantly in either direction.
- The vehicle speed is between approximately 0 MPH (0 km/h) and 90 MPH (145 km/h).
- Parking brake is released.

(2) Setting Adaptive Cruise ControlPress the RES/SET switch to the “SET/-”.
Adaptive Cruise Control is now set, and cruise
control will start.
If no vehicle in front has been detected, the
vehicle drives at the constant set target
speed.
When Adaptive Cruise Control is set, the set
speed and are displayed on the EyeSight
display area.
NOTE
x The target vehicle speed can be set between 25 MPH (40 km/h) and 90
MPH (145 km/h).
x If the vehicle speed is approximately 25 MPH (40 km/h) or less when the
vehicle speed is set, the set vehicle speed is set to 25 MPH (40 km/h).
x When driving on a curve, the vehicle may not accelerate, or may deceler-
ate, even if the set speed is higher than the current vehicle speed.
x If the (Adaptive Cruise Control indicator) does not illuminate, even
when the (CRUISE) switch is pressed, Adaptive Cruise Control will
not operate.
x If the (Adaptive Cruise Control indicator) does not illuminate, even
when the (CRUISE) switch is pressed, there may be a malfunction in
the system. Contact a SUBARU dealer and have the system inspected.

When a vehicle in front is detected, a buzzer
sounds 1 short beep and the lead vehicle
indicator will illuminate. (white) will turn
green.
The vehicle tracks the lead vehicle in front
and maintains the selected following distance.
At this time, the speed upper limit is the set
vehicle speed. If the vehicle in front is no
longer detected, a buzzer sounds 1 short
beep and the lead vehicle indicator turns off. (green) will turn white.
Operation of Adaptive Cruise Control x When no vehicle in front is detected
The vehicle drives constantly at the set tar-
get vehicle speed between approximately
25 MPH (40 km/h) and 90 MPH (145 km/h).
x When a vehicle in front is detected
The vehicle tracks the lead vehicle in front,
and will maintain the chosen following dis-
tance (there are three settings), up to the
set target vehicle speed - between 25 MPH
(40 km/h) and 90 MPH (145 km/h).
NOTE
The buzzer sound (lead vehicle acquisition sound) that occurs when a vehicle
in front is detected or no longer detected while Adaptive Cruise Control is set
can be turned off by customization.
Ÿ Refer to page 91.

xIf your vehicle no longer detects the vehicle
in front
The vehicle gradually accelerates back to
the set target vehicle speed and will drive at
that constant speed.
If a vehicle in front is detected while
accelerating to the set target vehicle speed,
vehicle tracking will be started again.
CAUTION
If the driver operates the brake pedal during automatic braking, the pedal
may feel stiff; however, this is not a malfunction. By depressing the brake
pedal further you can apply more braking force. When the brake pedal is
released it will return to its original condition.
NOTE
x When the brakes are applied by Adaptive Cruise Control, the vehicle’s
brake lights will illuminate.
x Even if there is no lead vehicle present, on a downhill grade, the Adaptive
Cruise Control’s automatic brake may operate in order to maintain the set
target vehicle speed.
x Some noises may be audible during automatic braking. This is caused by
the braking control and does not indicate a malfunction.
x To temporarily accelerate quickly, use the accelerator pedal. After acceler-
ating, the vehicle will gradually return to the set target vehicle speed shown
in the gauge cluster.
x There are cases where the vehicle in front has turned off the road while
your vehicle is still controlled by the automatic braking operation that has
activated due to the deceleration of the vehicle in front of yours. In those
cases, the brake will be automatically released gradually. Depress the
accelerator pedal if necessary.
x The lead-vehicle tracking function has the following characteristics:
- If the lead vehicle’s brake lamp is detected, deceleration is started more quickly than without detection.
- If the vehicle moves to the fast lane while traveling more than 37 MPH (60 km/h), the system starts acceleration to the set vehicle speed more
quickly because it is linked with the turn signal.

■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.
x 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.
x 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 multi information
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
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.

■Decreasing the set vehicle target speed
●
Using the RES/SET switch
While driving with Adaptive Cruise Control on, operate the RES/SET switch as follows.
x Push to the “SET/-” side briefly.
Every time the switch is pushed, the set
vehicle target speed will decrease in to the
next 5 MPH (5 km/h) decrement.
x Push to the “SET/-” side continuously.
While the switch is being pushed, the set
vehicle target speed will decrease by 1
MPH (1 km/h).
When operating the switch, the set vehicle
target speed changes on the multi informa-
tion display and the multi function display.
●Using the brake pedal
(1) Depress the brake pedal to decrease the vehicle speed. (Adaptive Cruise Control will be
canceled and will turned off.)
(2) When the desired speed is reached, press the RES/SET switch to the “SET/-”. The speed at the time of pressing the switch will be set as the new vehicle speed, and it
appears in the EyeSight display area.
■Accelerating temporarily
Depress the accelerator pedal to accelerate temporarily.
When the accelerator pedal is released, the vehicle returns to the set vehicle speed.
