Starting and operating/Parking your vehicle

a short sound several minutes after the
electronic parking brake indicator light
illuminates 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 accelerator pedal
The electronic parking brake system has
an automatic release function. 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.

NOTE
Even if you have applied the parking
brake, the parking brake will be automatically released when the accelerator pedal is depressed.
! Hill Holder function
The electronic parking brake system has a
Hill Holder function. If the Hill Holder
function is activated, the parking brake
will be automatically applied when stopping on an uphill slope with the brake
pedal depressed. In this case, the electronic parking brake indicator light and the
indicator light on the parking brake switch
illuminate.
The Hill Holder function also operates
while driving uphill in reverse.

NOTE
. The Hill Holder function may not
activate on a gentle uphill slope. In this
case, manually apply the electronic
parking brake.
. If you do not depress the brake
pedal sufficiently, the Hill Holder function may not operate properly. However, this is not a malfunction. When
stopping on an uphill slope, depress
the brake pedal firmly and release it
after the electronic parking brake in-

dicator light illuminates.
. Depending on the condition of the
road surface and braking force, the
brakes operate temporarily and feel
different than usual.
. When the electronic parking brake
system has a malfunction while the Hill
Holder function is activated, a chirp
sound is heard, the Hill Holder indicator light turns off and the brake system
warning light turns on.
. When the hill holder activates on a
slope, the electronic parking brake is
engaged. The electronic parking brake
will release when you accelerate from
the stop. If you manually release the
electronic parking brake while the hill
holder is activated, the hill holder
function is cancelled and will not reengage until the vehicle has moved
some distance. In that case, you will
need to manually engage the electronic
parking brake if needed.
