PEDAL - ADJUSTABLE
DESCRIPTION
The Adjustable Pedals System (APS) is designed to
enable the fore and aft repositioning of the brake and
accelerator pedals. This results in improved ergonom-
ics in relation to the steering wheel for taller and
shorter drivers. Being able to adjust the pedal posi-
tions also allows the driver to set steering wheel tilt
and seat position to the most comfortable position.
The effort required for pedal application will not
change regardless of pedal position.
The adjustable pedal system allows the pedals to
adjust up to 3 inches (75 mm) at a rate of approxi-
mately 0.4 in./sec. (9 mm/sec.). An adjustment switch
is located on the left side of the steering column
lower shroud.
If the vehicle is equipped with Remote Keyless
Entry (RKE), an optional memory feature is avail-
able.
The serviceable components of the APS are:
²Adjustable pedal assembly (includes motor,
cables, pedals, gear box, sensor and module)
²Adjustable pedal module (Refer to 8 - ELECTRI-
CAL/ELECTRONIC CONTROL MODULES/
ADJUSTABLE PEDAL MODULE)
²Adjustable pedal switch
²Pedal position sensor
OPERATION
Change of pedal position is accomplished by means
of a motor driven screw. Operating the adjustable
pedal switch activates the pedal drive motor. The
pedal drive motor turns a screw that changes the
position of the accelerator pedal. The motor also
drives a cable connected to a gear box that changes
the brake pedal position the same distance as the
accelerator pedal. The pedals can be moved rearward
(closer to the driver) or forward (away from driver).
Each pedal is moved on its activating lever to a posi-
tion where the driver feels most comfortable. The
position and operation of the activating levers are not
changed.
Pedal adjustment is inhibited when the vehicle is
in reverse or when cruise control is engaged. The
Electronic Vehicle Information Center (EVIC) will
display a message when the Adjustable Pedal Module
(APM) is disabled. i.e.:9Adjustable Pedal Disabled -
Cruise Control Engaged9or9Adjustable Pedal Dis-
abled - Vehicle in Reverse9.
Foot pressure or debris can stall pedal adjustment.
In order to avoid damage to system components dur-

ing pedal adjustment, the APM will monitor pedal
position sensor voltage. If the APM does not detect
expected voltage change within 3 seconds, it will cut
power to the adjustable pedal motor.
An optional memory feature is available. This
allows storing of one or two preferred pedal positions
in the APS. A preferred position can be stored and
recalled using the door-mounted switches. A stored
pedal position can be recalled (but not stored) using
the Remote Keyless Entry (RKE) if equipped with
the memory feature.
