Pre-Collision Braking System
23
xWhen you suddenly change lanes and your vehicle is immediately
behind an obstacle
x When there is a vehicle, motorcycle, bicycle or pedestrian in a location
close to your vehicle’s bumper
x When the speed difference between your vehicle and an obstacle is 4
MPH (5 km/h) or less (As braking is performed once the obstacle is in
close proximity to your vehicle, depending on the shape and size of the
obstacle, there may be some cases when the obstacle is outside the
range of the cameras’ field of view.)
x When driving on sharp curves, steep uphill grades or steep downhill
grades
x When driving on a bumpy or unpaved road
x When there are changes in brightness, such as at a tunnel entrance or
exit
x Do not test Pre-Collision Braking System on its own. It may operate
improperly and cause an accident.
x The system may not operate correctly under the conditions listed below.
When these conditions occur, turn off the Pre-Collision Braking System.
- The tire pressure is not correct.

- 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 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.

Pre-Collision Braking System
25
- When the exhaust gas emitted by the vehicle in front is clearly visible in coldweather, etc.
- When there is an obstacle on a curve or intersection
- When narrowly passing a vehicle or an object
- When stopping very close to a wall or a vehicle in front
x If there is cargo or installed
accessories, etc. that are pro-
truding over the edge of the
front bumper, the vehicle’s
length will increase and the
system may not be able to pre-
vent a collision.
x If the driver operates the brake pedal during automatic braking, the pedal may
feel stiff; however, this is normal. By depressing the brake pedal further you
can apply more braking force.
NOTE
Some unusual noises may be audible during automatic braking. This is
caused by the braking control and is normal.

Pre-Collision Braking System
27
When there is an obstacle in the forward direction during driving, the system activates in the
following sequence in order to warn the driver, activate braking control, and active the brake
lights.
Following Distance Warning:
When the system determines that there is a risk of collision, a buzzer sounds repeated short
beeps and the indicators on the multi information display illuminate to warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is not set.
When the driver depresses the brake pedal to decelerate and achieves a suitable following
distance, the warning is canceled.
First Braking and Warning:
When the system determines that there is a high risk of collision with an obstacle in front, a
buzzer sounds repeated short beeps and the indicators on the multi information display illu-
minate to warn the driver, and braking control is activated and the engine output, in some
situations, is also controlled. If the system determines that the amount of evasive action
(braking, steering, etc.) taken by the driver has reduced the risk of collision, braking activa-
tion is canceled.
Secondary Braking and Warning:
If the system then determines that the risk of collision is extremely high, the buzzer changes
to a continuous beeping sound and stronger braking control is activated. If, despite any eva-
sive action taken by the driver, the system subsequently determines that a collision is
unavoidable, braking control and the engine output control are continued.
Even after the vehicle has stopped, depress the brake pedal.

Until the brake pedal is depressed, a mes-
sage appears and stays in the warning screen
area of the multi information display for
approximately 2 minutes. A single continuous
beep sounds while the message is displayed.

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.

Pressing and holding the Pre-Collision Braking System OFF switch for approximately 2 sec-
onds (or longer) turns off the Pre-Collision Braking System (including Pre-Collision Brake
Assist). When 1 short beep sound emits, this control is turned off and the Pre-Collision
Braking System OFF indicator light on the instrument panel illuminates.
To turn the control back on, press and hold the Pre-Collision Braking System OFF switch for
approximately 2 seconds or longer again. When this control is turned on, the Pre-Collision
Braking System OFF indicator light turns off.
Turning off the Pre-Collision Braking System
NOTE
xWhen the Pre-Collision Braking System is turned off, the Pre-Collision
Throttle Management Control function is also turned off.
x Even when the Pre-Collision Braking System is turned off, if the ignition
switch is turned off and the engine is then restarted, the Pre-Collision
Braking System will be turned on. The system default setting when the
vehicle is restarted in “ON”.

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.

Continued on next pageŸ
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 fac-
tors), 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 a sharp curve into an interchange or junction, or a service area, parking area, toll booth or other facilities
Detection of the vehicle in front may not be possible.
- When there are 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, making correct control impossible.
- When there is snow, frost, dirt or dust on the windshield or it is clouded
S00652

Adaptive Cruise Control

ŸContinued from previous page
- 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 con-
trol impossible.
- When the stereo cameras’ field of view is obstructed (for example by a canoe on the roof of the vehicle)
x The 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)
xAn empty truck or trailer
that has no cargo in the
cargo bed being affected
by wind
x Vehicles that have cargo
protruding from their
back ends
x Non-standard shaped vehicles (vehicle transporters or vehicles with a
sidecar fitted, etc.)
x Vehicles that are low
- Objects that are located close to the bumper of your vehicle
x When 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.
x Before 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.)
