POWER SEATS - SERVICE INFORMATION
DESCRIPTION
POWER SEAT SYSTEM
WARNING: The front passenger seat assembly contains critical components that affect the front passenger
airbag deployment. Correctly functioning front passenger seat components are critical for the Occupant
Classification System (OCS) to properly classify the front passenger and calculate the proper airbag deploy-
ment. Unapproved modifications or service procedures to the front passenger seat assembly, its related
components, or trim cover may inadvertently change the airbag deployment in case of a frontal crash. This
could result in death or serious injury to the front seat passenger if the vehicle is involved in an accident.
The following requirements must be strictly adhered to:
•
Do not modify the front passenger seat assembly or components in any way.
•
Do not modify the front seat center console or center position seat in any way.
•
Do not use prior or future model year seat trim covers not designated for the specific model being
repaired. Always use the correct seat trim cover specified for the vehicle.
•
Do not replace the seat trim cover with an aftermarket trim cover.
•
Do not add a secondary trim cover other than those approved by DaimlerChrysler/Mopar.
•
At no time should any Supplemental Restraint System (SRS) component or SRS related component or
fastener
be
modified
or
replaced
with
any
part
except
those
which
are
approved
by
DaimlerChrysler/Mopar.
