and when the GEM detects the headlamps or parklamps are on from the exterior lamp circuits. Refer
to the Chime Duration Table in this section for audible output, duration time, and priority ratings.
Safety Belt Warning Chime
The safety belt warning chime and safety belt warning lamp activate when the GEM detects the
ignition switch circuits are in the RUN or START state and when the GEM detects the safety belt is
unbuckled from the safety belt circuit. The safety belt warning lamp indicator will prove out for three
seconds whenever the GEM detects that the ignition circuits make a transition to RUN from OFF, ACC,
or KEYOUT state. Refer to the Chime Duration Table in this section for audible output, duration time,
and priority ratings.
Belt Minder
NOTE:
Belt minder is a configurable item. If configuring using a diagnostic tool, refer to Section 418 -
01 . To configure without using a diagnostic tool, refer to
Belt Minder Deactivating/Activating in this
section.
The belt minder feature supplements the current safety belt warning function. The belt minder feature
is enabled after the current safety belt warning is complete. If the driver safety belt is not buckled
approximately five seconds after the safety belt warning light has turned off, the belt minder reminds
the driver that their safety belt is unbuckled by intermittently sound a chime and illuminating the safety
belt warning lamp in the instrument cluster. While activated, the belt minder alternates the chime and
indicator from on for six seconds to off for 30 seconds.
The belt minder reminder stops when:
zthe drive seat belt is buckled.
z the ignition is turned to OFF or ACC.
z five minutes have elapsed since belt minder has started.
Inspection and Verification
NOTE: Upon installation of a new GEM, the module must be reconfigured. For additional information,
refer to Section 418 - 01 .
1. The warning lamps are a GEM controlled system; refer to Section 419 - 10 .
2. Verify the customer concern by operating the system in question.
3. Visually inspect for the following obvious signs of mechanical and electrical damage.

The front power seat features:
za six- way seat regulator control switch (14A701) located on the front of the seat.
z a seat track (61705) mounted under the seat.
z a seat regulator motor (14547) and gear housing mounted on the seat track (61705).
z an optional power lumbar switch located on the outboard side of the seat (14C715).
z a manual seat backrest release handle on the outboard rear corner of the seat.
z an optional power bolster and lumbar switches located on the inboard side of the seat (Cobra
only)
Seats — Power Lumbar Support
NOTE: The pump and solenoid module are serviced as an assembly with the front seat cushion frame
(Cobra only). The backrest bolster/lumbar adjusting pads are serviced together and the cushion
bolsters are serviced separately.
