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. Please remember
that you should not exceed posted speed limits. The vehicle is not equipped with a function
that helps maintain the vehicle’s standstill position without a driver’s operation.

WARNING
xThis system does not provide the driver with an automatic driving function
that handles all traffic conditions.
xDo 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.
xSet the set vehicle speed within a range that is appropriate to the road con-
ditions and surrounding environment.
xThe 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.*
- The temporary spare tire is installed on any wheel.*
- Tires that are worn or have large variations in wear conditions are
installed.*
- Tires other than those of the designated size are installed.*
- An emergency repair is performed using the flat tire repair kit.
- The suspension has been modified.
- Tire chains are installed.
- The headlights are dirty or the optical axes are not aligned correctly.
(Objects are not correctly illuminated and are difficult to detect.)
- Vehicle operation has become compromised due to an accident or mal-
function.
- The brake warning light is illuminated.
- The vehicle is tilted due to a heavy cargo load.
- The maximum number of occupants and/or the gross vehicle weight rat-
ing has been exceeded.
- When towing a trailer or another vehicle, etc.
*The wheels and tires have functions that are critically important. Be sure
to use the correct parts. For details, refer to the Owner’s Manual for your
vehicle.
xAdaptive Cruise Control is designed for use on expressways, freeways, toll
roads, interstate highways and similar limited access roads. It is not
intended to be used in city traffic. In the following conditions, do not use
Adaptive Cruise Control. Doing so may result in an accident.
- Ordinary roads (roads other than those mentioned above)
Depending on the driving environment (complexity of roads and other
factors), the system may not be able to perform as the traffic conditions
require, and that may result in an accident.
- Roads with sharp curves or winding roads
- Frozen roads, snow-covered roads or other slippery road surfaces
The tires may spin, causing loss of control of the vehicle.

- Traffic conditions when frequent acceleration and deceleration make it diffi-
cult to maintain the following distance
It may not be possible for the system to perform as the traffic conditions
require.
- Steep downhill grades
The set vehicle speed may be exceeded.
- On a steep continuous downhill grade
The brakes may overheat.
- Roads and overpasses with repeated steep uphill and downhill grades
Detection of the vehicle in front may be lost, or the road surface may be
detected instead of the vehicle in front, making correct control impossible.
- When entering an interchange, service area, parking area, junction, toll
booth or other facility
Detection of the vehicle in front may not be possible.
- When there are sudden changes in brightness, such as at a tunnel entrance
or exit
- When visibility is poor due to sand, smoke or water vapor blowing in the
wind, or when the vehicle in front or oncoming traffic causes water, snow,
dirt or dust to obscure the view
Detection of the vehicle in front may be lost, or water or other substances
may be incorrectly detected instead of the vehicle, making correct control
impossible.
- When there is snow, frost, dirt or dust on the windshield or it is clouded
- When water droplets from rain or the window washer, or dirt has not been
fully wiped off the windshield
It may not be possible to detect the vehicle in front, making correct control
impossible.
- When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)

xThe stereo cameras may have difficulty detecting the following objects or
conditions. Operate the brake pedal and take other actions as necessary.
- Vehicles at significantly different speeds (vehicles driving slowly,
stopped or oncoming vehicles, etc.)
- Vehicles cutting into your lane
- Motorcycles, bicycles, pedestrians and animals, etc.
- When light is poor in the evening or early morning
- When driving at night or in a tunnel without the headlights on
- When driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
- When affected by strong light from the front (sunlight or headlight high
beams, etc.)
- Vehicles in front that have
a rear aspect that is low,
small or irregular (the sys-
tem may recognize
another part of the vehicle
and will determine opera-
tion from that)
• An empty truck or trailer
that has no cargo in the
cargo bed being affected
by wind
• Vehicles that have cargo
protruding from their back
ends
• Non-standard shaped ve-
hicles (vehicle transport-
ers or vehicles with a sidecar fitted, etc.)
• Vehicles that are low
- Objects that are located close to the bumper of your vehicle
xWhen you do not want to use Adaptive Cruise Control, be sure to turn the
(CRUISE) switch off. If the switch is left on, cruise control may be
accidentally engaged, possibly resulting in an accident.
xBefore using Adaptive Cruise Control, be sure to fully verify the safety of
the vehicle occupants and the area around the vehicle. Never operate the
cruise control from outside the vehicle.

Detection of the vehicle in front by the EyeSight stereo cameras
xUnder the following road conditions or conditions of your vehicle, detection
of the vehicle in front may not be possible. Vehicles in neighboring traffic
lanes or roadside objects may also be incorrectly detected. Under condi-
tions such as these, do not use Adaptive Cruise Control. If cruise control is
currently in use, operate the brake pedal and take other action as neces-
sary.
- When tracking begins from
a short following distance,
such as when the vehicle
in front is a vehicle that cut
into your lane
- When driving on curved
roads, at the start and end
of a curve and on roads
with continuous curves
(These conditions make it
difficult for the system to
detect vehicles because
they are outside the
detectable area.)
- When driving on an on-
ramp or off-ramp to a free-
way, highway, or other
restricted access road
(EyeSight Adaptive Cruise
Control is not designed for
use in this kind of driving environment.)
- When driving in an urban, or suburban environment (Adaptive Cruise
Control is not appropriate for use in these driving areas. Adaptive Cruise
Control should only be used on limited-access highways.)

- 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 speed difference with the vehicle (or object) in front is more
than 20 MPH (30 km/h)
- When a vehicle cuts into your lane in front of you
- When the distance between vehicles is extremely small
- When your vehicle is drifting within the lane
- When driving on a bumpy or unpaved road surface
- When driving on a road with extremely narrow lanes, such as when traf-
fic 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
xThere 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.
xBefore using the system, perform a daily inspection and verify that there
are no malfunctions of the tires or brakes.
*Refer to the separate “Warranty and Maintenance Booklet”.
xIf the buzzer sounds frequently, do not use Adaptive Cruise Control.

xEven when the following distance is short, the “brake more” warning may
not activate in the following cases.
- When the 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
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 because the vehicle in front has stopped, the automatic braking
function will be cancelled immediately after stopping and the vehicle will
start creeping forward gradually (at the same time three short beeps and a
single long beep will sound). Be sure to depress the brake pedal and stop
the vehicle completely.
Note that the vehicle is not maintained at a standstill position and will not
automatically start moving from a standstill position.
xBraking 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 the speed to potential obstacles is more than 20 MPH (30 km/h)

When there is no vehicle in front in the same lane, the vehicle drives constantly at the set
vehicle speed. When there is a vehicle in front in the same lane, the vehicle tracks the vehi-
cle in front up to the maximum set vehicle speed. When the vehicle stops because the vehi-
cle in front has stopped, the automatic braking function will be cancelled immediately after
stopping and the vehicle will start creeping forward gradually. 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.
■“Brake more” warning
When the system determines that braking applied by Adaptive Cruise Control will be insuffi-
cient, a buzzer will sound and an indicator in the meter display will illuminate to warn the
driver.
Also, a pop-up screen will be displayed in the multi function display.
* Refer to page 42.
Functions of Adaptive Cruise Control
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
xVehicles in front in the same traffic lane are detected by the stereo cam-
eras within a distance of approximately 265 ft (80 m) in the forward direc-
tion. However the detection distance may be reduced depending on the
traffic environment, driving conditions, and conditions of the vehicle in
front.
xChanging the SI-DRIVE mode allows adaptive cruise control to track the
vehicle in front utilizing the characteristics of each mode.
xWhen 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.
xIf the (Adaptive Cruise Control) is not displayed when the
(CRUISE) switch is pressed, there may be a malfunction in the system.
Contact a SUBARU dealer and have the system inspected.
xSome noises may be audible during automatic braking. This is caused by
the braking control and does not indicate a malfunction.
