Be careful with the type of seat cover you use. They affect the airbag sensors in the passenger front seat.
From page 49 of the 2006 owners manual:
"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 deployment. Do not make any modifications to the front passenger seat components, assembly, or to the seat cover.
The following requirements must be strictly adhered to:
1. Do not modify the front passenger seat assembly or components in any way.
2. Do not modify the front seat center console or center position seat in any way.
3. Do not use prior or future model year seat covers not designated for the specific model being repaired. Always use the correct seat cover specified for the vehicle.
4. Do not replace the seat cover with an aftermarket seat cover.
5. Do not add a secondary seat cover other than those approved by DaimlerChrysler/Mopar.
Warning!
Unapproved modicications or service procedures to the front passenger seat assembly, its related components, or seat cover may inadvertently change the airbag deployment in case of frontal crash. This could result in death or serious injury to the front seat passenger if the vehicle is involved in an accident."
