2021 SUBARU ASCENT brake

OPERATION
EyeSight®is a driver assist technology that
uses dual color cameras to serve as an extra
pair of eyes on the road ahead to identify
vehicles in front, pedestrians, traffic lanes, or
other objects. If need be, the EyeSight
®
system can apply the brakes and/or reduce
engine power to help avoid or reduce the
severity of a collision. During these events, the
system will provide audible and visual alerts to
assist you in making decisions.
Since the characteristics and limitations of the
EyeSight
®color cameras are similar to human
eyes, it is important that the cameras,
windshield, and area in front of the cameras
are treated with special care. Please refer to
“Care and Limitations” on page 100 for more
details.
FUNCTIONS
The EyeSight®system features several distinct functions designed to provide extra
awareness, improve safety, reduce fatigue, and add peace of mind every time you drive
your Subaru. EyeSight
®functions include:
• Pre-Collision Braking (PCB)
• Pre-Collision Brake Assist
• Pre-Collision Throttle Management
• Lane Departure Warning (LDW)
• Lane Sway Warning
• Lane Departure Prevention
• Advanced Adaptive Cruise Control
• Advanced Adaptive Cruise Control (AACC)

Pre-Collision Braking
This function helps prevent or minimize a
frontal collision with another vehicle,
pedestrian, or other objects by providing
visual and audible warnings. Warnings are
displayed in the Combination Meter Display
(CMD) with audible beeps. If you take no
corrective action, the system automatically
reduces engine power and applies the brakes
with increasing force to help prevent or
minimize the collision.
This system can be turned on or off by using
the Pre-Collision Braking System OFF switch
(see page 96).
Pre-Collision Brake Assist
This function recognizes a possible collision with another vehicle, a pedestrian, or object in
front while you are applying the brakes. If the system determines not enough force is
applied, it can assist by applying additional pressure to the braking system to decrease
stopping distance.
This system can be turned on or off by using the Pre-Collision Braking System OFF switch
(see page 96).
Pre-Collision Throttle Management
This function is designed to help prevent you from unintentionally accelerating into a
stopped vehicle or other obstacle by reducing engine power. Warnings are displayed in the
Combination Meter Display (CMD) with audible beeps.
Pre-Collision Throttle Management is helpful when:
• You unintentionally place the select lever in the “D” position instead of the “R” position
and start to accelerate toward a parked car, wall or parking structure.
• While you are at a stop, the vehicle ahead of you accelerates, but then suddenly slows
down or stops as you begin to accelerate.
This system can be turned on or off by using the Pre-Collision Braking System OFF switch
(see page 96).

Lane Departure Prevention
This function provides steering assistance to
keep you in the lane of travel when driving on
expressways, freeways, and interstate
highways at approximately 37 mph or greater.
Lane Departure Prevention uses the EyeSight
®
camera to identify lane markings and assists
steering operation to help prevent lane
departure.
This function is turned on or off using the Lane
Keep Assist button on the right side of the
steering wheel. Once the system is turned on,
a white Lane Keep Assist icon will be
displayed on the Combination Meter Display
(CMD). Lane marking graphics on the CMD
change to white to indicate that the right and/or left lane markings have been successfully
identified by the EyeSight
®camera. If the vehicle is about to depart the driving lane, the
system assists steering by gently guiding the vehicle back into your lane. When the system
is actively providing assistance, the Lane Keep Assist icon in the CMD will change from
white to green.
Advanced Adaptive Cruise Control with Lane Centering
Advanced Adaptive Cruise Control is a driving support system intended to reduce the
burden on you when driving on an expressway (including during congestion and when
driving at high speed). Advanced Adaptive Cruise Control and Lane Centering work
together to assist you by automatically controlling the accelerator, brake, and steering.
Advanced Adaptive Cruise Control
This system provides cruise control with the
ability to keep a safe distance from the car in
front of you. Using the EyeSight
®camera, the
Advanced Adaptive Cruise Control function
identifies vehicles in front of you in the same
lane, and your vehicle follows the vehicle in
front (up to the maximum of your set speed).
While following, your vehicle will automatically
maintain a following distance that
corresponds to the speed of the vehicle in
front. The vehicle is capable of being
controlled at a speed between 0 mph and
approximately 90 mph.

HIGH BEAM ASSIST (HBA)
This function uses the EyeSight®cameras to automatically switch
the headlights between high and low beam settings when an
oncoming vehicle is detected, enhancing safety for both you and
other drivers on the road.
To activate High Beam Assist, set the headlight control switch to the
“AUTO” position and push the headlight lever forward to the high beam position. The
green HBA indicator will illuminate on the Combination Meter Display (CMD). When vehicle
speed is above approximately 20 mph, HBA will automatically switch between high and
low beams. When the high beams are activated, the blue high beam indicator will be
displayed in the Combination Meter.
STEERING RESPONSIVE HEADLIGHTS (SRH)
The Steering Responsive Headlights (SRH) system aims the headlight beams in the
direction you are steering, improving visibility at corners and intersections when driving at
night. You can turn the SRH system on or off using the steering wheel mounted “i/SET”
switches to access the settings menu on the Combination Meter Display (CMD).
REVERSE AUTOMATIC BRAKING (RAB)(if equipped)
This system uses four rear bumper mounted sonar
sensors to detect objects when moving between
1 and 9 mph in reverse. RAB uses the Rear-Vision
Camera image to display colored proximity alerts
when an object is detected. As an object becomes
closer to the rear of your vehicle, audible beeps
provide additional awareness in three progressive
levels. If RAB determines that a collision with an
object is possible, the system can automatically apply
the brakes to help prevent or minimize the impact.
In some cases, such as connecting a trailer, it may be helpful to temporarily turn the
system off. RAB can be turned off using the Touchscreen buttons on the lower corners
when the select lever is in the “R” position.
Select and hold the “RAB ON” button in the lower part of the Touchscreen
until it changes to “RAB OFF” to disable the automatic braking functions of
the RAB system.
Select and hold the “P))) ON” button in the lower part of the Touchscreen until
it changes to “P))) OFF” to disable the audible beeping of the RAB system.
