ELECTRONIC PARKING BRAKE OVERRIDE
The 2013 Lexus GS series vehicles are equipped with an electrically applied parking
brake. Power is needed in the vehicle to apply and release the parking brake which can
be set to function automatically when the vehicle is shifted in and out of PARK (P). In
the event that the battery is discharged or the switch, mounted in the dash to the lower
right of the steering wheel, will not release the parking brake, an override procedure is
incorporated into the system.
The first step is to ensure there is battery power in the vehicle so perform your normal
diagnostic procedure to ensure the battery is functioning. If there is any question as to
the state of charge of the battery, hook your jump starting system to the vehicle following
all the procedures outlined in the jump starting section of this service guide and follow all
normal jump starting precautions.
