■“Brake more” warning
The “brake more” warning is activated while Adaptive Cruise Control is tracking a lead vehi-
cle. This function warns the driver when it determines that the current level of deceleration
by automatic braking control is insufficient.
x When the ‘brake more’ function operates,
“Obstacle Detected” will be shown in the
warning screen area of the multi information
display, a lead vehicle indicator will flash,
and a buzzer will sound several short
beeps.
x When this function activates, depress the
brake pedal to decelerate and maintain a
correct following distance.
Other functions
WARNING
xIf the buzzer sounds frequently, do not use Adaptive Cruise Control.
x The “brake more” warning will not activate in the following situations.
- The accelerator pedal is depressed.
- The brake pedal is depressed.
x 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 traveling 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
x 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 intersec-
tion 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 obstacle and react to it.

Lane Keep Assist
The stereo cameras detect lane markings
(including Botts’ dots) of the lane and the sys-
tem assists the steering operation by working
with the electric power steering to help keep
your vehicle in its lane when driving on
expressways, freeways and interstate high-
ways.
WARNING
Lane Keep Assist is not an automatic driving system.
Do not overestimate the capabilities of Lane Keep Assist. It is not a sys-
tem to assist inattentive driving or meant to permit driving without hold-
ing the steering wheel. Make sure to grip the steering wheel while
driving. To drive safely, check the distance from the vehicle in front or
from a vehicle driving in parallel with your vehicle, the surrounding con-
ditions and the surrounding environment while driving.
If you feel that the level of control and timing by the system are different from
your own driving style, the system may not support safe driving. Do not use
Lane Keep Assist.
Lane Keep Assist does not always operate under all situations. If you rely
only on the Lane Keep Assist to stay in a lane, it may cause an accident such
as a collision with an obstacle beside your lane or with a vehicle driving in an
adjacent lane.x Check that there are no problems with the tires and brakes during a daily
inspection before using the system.
Ÿ Refer to “Warranty and Maintenance Booklet”.
x The system may not operate properly under the following conditions. Do
not use Lane Keep Assist.
- The air pressure of tires is not to specification.
*1
- Tires that are unevenly worn or tires with uneven wear patterns are installed.*1
- Tires that are the wrong size are installed.*1
- The wheel balance is abnormal (e.g., the balance weight is removed ormisaligned.)*1
- The wheel alignment is out of the specified value.*1
- Flat tires have been fixed temporarily with a tire repair kit.
- The suspension has been modified (including genuine SUBARU parts).

Pre-Collision Throttle Management
When an obstacle is detected in front of the
vehicle, and the vehicle is stopped or traveling
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 warning screen 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 colli-
sions in many situations. Always check the select lever and pedal posi-
tions as well as the surrounding environment before starting and
operating the vehicle. Relying only on Pre-Collision Throttle
Management could result in an accident.x Pre-Collision Throttle Management is not designed to maintain the vehicle
in a stopped condition.
x Pre-Collision Throttle Management will not reduce acceleration under all
conditions. It is also not designed to prevent collisions.
x 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.)
x 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.

Conventional Cruise Control
Conventional Cruise Control is a driving support system intended to allow more comfortable
driving on expressways, freeways and interstate highways. It can be used to travel at a con-
stant speed by maintaining the vehicle speed that was set by the driver. Please remember
that you should not exceed posted speed limits.
About Conventional Cruise Control
WARNING
xWhen Conventional Cruise Control is functioning, the system does not per-
form tracking control to maintain following distance, as when using Adap-
tive Cruise Control.
Strive for safe driving and operate the brake pedal to decelerate the vehi-
cle as necessary in order to ensure a safe following distance from the vehi-
cle in front.
x Under the following conditions, do not use the Conventional Cruise
Control. Doing so may result in an accident.
- Roads with heavy traffic or roads with sharp curves You may fail to drive at a speed that is appropriate for the road condi-
tions, possibly resulting in an accident.
- Frozen roads, snow-covered roads or slippery road surfaces The tires may spin, causing loss of control of the vehicle.
- Steep downhill grades The set vehicle speed may be exceeded.
- On a steep continuous downhill grade
The brakes may overheat.
CAUTION
When using Cruise Control, be sure to check the EyeSight display area to
confirm which Cruise Control mode is selected: Adaptive Cruise Control or
Conventional Cruise Control.x If Adaptive Cruise Control is selected,
