WARNING
Read pages 2 - 4 of this installation manual before beginning the
installation. Failure to do so could result in significant vehicle damage.
Check for obstructions prior to drilling. Failure to do so could result in
damaged fuel or brake lines, structural members, etc.
CURT does its best to communicate tow vehicle manufacturer
changes. However, it is ultimately the responsibility of the installer
to prevent damage due to installation.
