2016 SUBARU LEGACY engine

Adaptive Cruise Control
37
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.
xThere is no possibility that the vehicle will automatically begin moving from
a stay-stopped condition without operation from the driver.
xIf the conditions for automatically canceling cruise control (
Ÿ refer to page
49) are met while the vehicle is stay-stopped, Adaptive Cruise Control is
canceled and for safety reasons, the electronic parking brake is automati-
cally applied.
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 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 electronic parking brake is not
engaged (The brake system warning light
is turned off.).
- The selector 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 87.
- The road is not a steep slope.
- The steering wheel has not been turned significantly in either direction.
- X-mode is not turned on.
- The vehicle speed is between approximately 0 MPH (0 km/h) and 90 MPH (145 km/h).

WARNING
Do not use Adaptive Cruise Control on slippery roads. Doing so may result in
an accident.
CAUTION
When shifting the selector 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.
xIf 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.
xWhen 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.

Lane Keep Assist
57
CAUTION
xThe performance of Lane Keep Assist may not be optimal under the following
conditions. In addition, Lane Keep Assist may not operate or the operation
may be canceled.
- Immediately after the weight of your vehicle changes radically
- Immediately after the replacement of a tire or the adjustment of tire pres-
sure
- Immediately after the adjustment, repair or replacement of cameras or
related components
- Immediately after the repair or replacement of the suspension or steering
system
- A winter tire or a tire other than a genuine SUBARU tire is used.
- The vehicle is in a crosswind.
- The road grade abruptly changes (uphill or downhill).
- The grade of the crossing direction in a road is large or changes abruptly.
- Unevenness, winding and joint of a road surface
- The acceleration/deceleration is high.
- Immediately after starting the engine when the outside temperature is low.
- The outside temperature is high.
xWhen you do not use Lane Keep Assist, make sure to turn off the (Lane
Keep Assist) switch. If you turn it on, the function may operate unexpectedly,
causing an accident.
xIf you turn on the (Lane Keep Assist) switch, the operation power of
electric power steering may change.

Pre-Collision Throttle Management
When an obstacle is detected in front of the
vehicle, and the vehicle is stopped or travel-
ling 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 pop-up display 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 selector lever and pedal
positions as well as the surrounding environment before starting and
operating the vehicle. Relying only on Pre-Collision Throttle
Management could result in an accident.
xPre-Collision Throttle Management is not designed to maintain the vehicle
in a stopped condition.
xPre-Collision Throttle Management will not reduce acceleration under all
conditions. It is also not designed to prevent collisions.
xPre-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.)
xDo 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.

CAUTION
xIn the following situations, turn off Pre-Collision Throttle Management. Other-
wise Pre-Collision Throttle Management may activate unexpectedly.
- When the vehicle is being towed
- When loading the vehicle onto a carrier
- When a chassis dynamometer, free-rollers or similar equipment is used
- When a mechanic lifts up the vehicle, starts the engine and allows the
wheels to spin freely
- When passing hanging banners, flags or branches, or when thick/tall vege-
tation is contacting the vehicle
xThe Pre-Collision Throttle Management may activate in the following situa-
tions. Therefore concentrate on safe driving.
- When your vehicle is close to the vehicle in front
- When passing through an automatic gate
- When your vehicle is in a location where the grade of the road changes
rapidly
- When passing through clouds of steam or smoke
