Warning: If the 12V power supply is disconnected, do not attempt to open any doors with door glass in closed position. Failure to follow this instruction could result in door glass shatter.

Note: Before disconnecting the 12V power supply, ensure that the driver's door window is fully open. Failure to follow this instruction could result in vehicle lockout.

Removal

  1. Remove the 12V battery bracket beam (refer to procedure).
  2. If the vehicle is equipped with air suspension, release the bolts (x2) that secure the air reservoir (torque 2.5 Nm). Carefully set the reservoir in the RH side of the underhood area.

    Note: It is not necessary to disconnect the air lines.
