Brake System - Subaru Ascent 2023 Manual

Braking
a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.
& Brake system
! Two separate circuits
Your vehicle has two separate circuit brake
systems. Each circuit works diagonally
across the vehicle. If one circuit of the
brake system should fail, the other half of
the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. A much longer
distance will be needed to stop the vehicle.
! Electronic brake booster
The vehicle is equipped with an electronic
brake booster to provide additional braking
force. Do not turn off the ignition switch
while driving because that will turn off the
brake booster, resulting in poor braking
power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, you will have
to depress the pedal much harder than
during normal braking, and the braking
distance will increase.
NOTE
When the following operations are
performed, an operating sound from
the electronic brake boost control
module may be heard. This is not a
malfunction.
. The brake pedal was operated.
. The driver's door was opened.
. The EyeSight function was acti-
vated.
. Several minutes have passed after
the engine stopped.
! Supplemental booster function
when pressure fails
If there is a malfunction in the braking
system, the power for the braking will be
stored by controlling the hydraulic pres-
sure of the VDC system.
When the brake pedal is depressed while
the supplemental booster function is oper-
ating, an operation sound and brake pedal
vibration may be generated.
! Brake assist system
WARNING
Do not be overconfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.
CAUTION
When you need to brake suddenly,
continue depressing the brake pedal
strongly to bring the effect of the
brake assist.
Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.
NOTE
When you depress the brake pedal
strongly or suddenly, the following will
occur. However, even though these
occur, they do not indicate any mal-
functions, and the brake assist system
is operating properly.
. You might feel that the brake pedal is
applied by lighter force and gener-
ates a greater braking force.
. You might hear an ABS operating
noise from the engine compartment.
