tools to avoid dirt and stains.
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.



A pilot hole made with a smaller
drill bit may help.
Take care to not damage
the seat cushion. Limit the drill bit
depth to prevent seat cushion
contact.
