Starting and operating/Parking your vehicle
brake system has a malfunction.
– When the electronic parking
brake operation is prohibited tem-
porarily.
. When you cannot release the park-
ing brake due to, for example, a system
malfunction, contact your SUBARU
dealer and have your SUBARU dealer
release the parking brake.
. If you stop operating the electronic
parking brake switch midway or oper-
ate extremely slowly, the system may
detect an error and turn on the brake
system warning light. However, this
does not indicate a malfunction if the
brake system warning light turns off
after operating the switch.
. When the electronic parking brake
has not been used for a long period of
time, the electronic parking brake may
operate automatically after the ignition
switch is turned to the "LOCK"/"OFF"
position. This occurs due to checking
the proper operation of the electronic
parking brake and does not indicate a
malfunction.
. If you cannot release the electronic
parking brake due to the switch mal-
function, refer to the instructions de-
scribed in "Automatic release function
by accelerator pedal" F7-44.
After activating the electronic parking
brake, you may hear a short sound
several minutes after the electronic
parking brake indicator light illumi-
nates as the system confirms proper
engagement. This sound is different
from the apply and release sound.
This can occur:
– If the brakes are extremely hot.
– If the car is parked on a steep
incline.
– If the electronic parking brake is
applied after the ignition switch is
turned OFF.
This is a normal operating sound under
any of these conditions.
! Automatic release function by ac-
celerator pedal
The parking brake will be automatically
released by depressing the accelerator
pedal. However, the automatic release
function does not operate under the
following conditions.
. Any door (other than the trunk lid) is
open.
. The driver's seatbelt is not fastened.
If the parking brake is automatically
released, the electronic parking brake
indicator light and the indicator light on
the parking brake switch turn off.
! Emergency brake
CAUTION
Use the emergency brake only in
case of an emergency. If the emer-
gency brake is excessively used, the
brake parts will wear down faster or
the brake may not work sufficiently
due to brake overheating.
NOTE
While using the emergency brake:
. The electronic parking brake indica-
tor light and the indicator light on the
parking brake switch illuminate and a
chirp sounds.
. A sound may be heard from the
engine compartment. This is the oper-
ating sound of the brake that is acti-
vated by the Vehicle Dynamics Control
system, and does not indicate a mal-
function.
If the foot brake has a malfunction, you can
stop the vehicle by pulling the parking
brake switch continuously.
While applying the emergency brake, the
electronic parking brake indicator light and
the indicator light on the parking brake
switch illuminate and a chirp sounds.
