Information

NOTE: Incorrect handling of main wire harness

Risk of damage to lines

→ The main wire harness contains all airbag lines, antenna lines and optical waveguides.

→ The main wire harness must not be separated and is always replaced as a complete wire harness when carrying out extensive repairs.

→ If individual lines are damaged, shut off these lines and install new lines. Lay the new lines along the main wire harness and secure them to the main wire harness.
