All suspension fasteners are important attaching parts in that they could affect the performance of vital parts and systems, and/or could result in major service expense. Any part must be replaced with one of the same part number or with an exact equivalent part if replacement becomes necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during assembly to ensure proper part retention.
If equipped with air suspension, the air suspension switch, located in the trunk on the right-hand trim panel, must be turned OFF before raising the vehicle. Failure to turn the air suspension switch off may result in unexpected inflation or deflation of the air springs, which may result in the vehicle shifting, possibly causing personal injury.
