SERVICE PROCEDURE
WARNING: This procedure involves working under the driver or front passenger seat. The
metal seat frame has sharp edges.
CAUTION: Handle interior trim carefully to avoid damage. Work with clean hands and clean
tools to avoid dirt and stains. Position clean suitable covering in the area where work is
being performed. Be generous with covering since grease will be brought inside the vehicle.
IMPORTANT: Follow all cautions, warnings, and notes in the Electronic Service Manual
(ESM) when working on or near a Supplemental Restraint System (SRS), such as an air
bag or OCS components.
NOTE:

Perform SERVICE PROCEDURE only on noisy seats.
 See page 1, IF YOU CONFIRM, for noise description.

For this bulletin’s service procedure, noisy seats equipped with climate control will need
to be unbolted from the floor and tilted fore or aft to access the lower seat trim.
 When a climate controlled passenger seat is repaired, Zero Point Reset will need to
be performed after the seat is bolted in/resecured.

Non-climate controlled seats do not need to be unbolted. The lower seat trim can be
accessed by reaching underneath.
Center console
1. Determine if the noisy seat is equipped
with climate control (see Figure 1).

Look for control knobs located on
the center console.

Climate Controlled Seats
NOTE: For easier viewing, a climate controlled seat has been removed from the vehicle.
Climate controlled seats only need to be unbolted and do not need to be removed from the
vehicle to perform this service procedure.
1. Unbolt the noisy climate controlled seat,
and then tilt fore or aft. (see Figure 2).
NOTE:
 Driver seat shown, passenger seat
similar.

The headrest may need to be removed
to allow seat tilting.

When moving the seat fore and aft (to
access the bolts), make sure the seat
tracks stay “in sync” with each other.

Do not disconnect any seat electrical
connectors.

Non-Climate Controlled Seats
NOTE:

For easier viewing, a non-climate controlled seat has been unbolted (see Figure 6).
Non-climate controlled seats do not need to be unbolted or removed to perform this
service procedure.

Driver and passenger non-climate controlled seats are similar underneath. Your
vehicle’s seat configuration may differ slightly.
1. Adjust the seat all the way back, and
then partially recline the seatback
toward the rear.

This will give working room away
from the center console.
2. Reach under the seat to locate the
elastic strap, and then unfasten it
(see Figure 6 and 7).
