WARNING
Do not use Adaptive Cruise Control on slippery roads. Doing so may result in
an accident.
CAUTION
When shifting the select lever to the position, Adaptive Cruise Control will
be automatically canceled. Do not shift the lever to the position unless it is
an emergency. Otherwise the engine brake may not operate, which could
cause an accident.
NOTE
xIf EyeSight operation has temporarily stopped, the Pre-Collision Braking
System OFF indicator light and Lane Departure Warning OFF indicator
light illuminate, and the EyeSight temporary stop indicator is displayed on
the multi information display.
Ÿ Refer to page 87.
x If EyeSight is malfunctioning, the EyeSight warning indicator is displayed
on the multi information display, and the Pre-Collision Braking System
OFF indicator light and Lane Departure Warning OFF indicator light will
also illuminate. If this occurs, stop the vehicle in a safe location and then
turn off the engine and restart it. If the indicators remain illuminated after
restarting the engine, Adaptive Cruise Control cannot be used. This will not
interfere with ordinary driving; however the system should be inspected by
a SUBARU dealer as soon as possible.
Ÿ Refer to page 86.
x When the operation of Adaptive Cruise Control has been automatically
canceled, perform the set cruise control operation again after the condition
that caused the cancellation has been corrected. If the cruise control func-
tion cannot be set even after the condition has been corrected, EyeSight
may be malfunctioning. This will not interfere with ordinary driving; how-
ever contact a SUBARU dealer and have the system inspected.

■“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.

Obstacle
Detected

Adaptive Cruise Control
53
NOTE
Vehicles in front in the same traffic lane are detected by the stereo cameras
within a distance of approximately 360 ft (110 m) in the forward direction.
However the detection distance may be reduced depending on the traffic
environment, driving conditions, and conditions of the vehicle in front.

54
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).
