Under certain conditions, the Driver Information Center (DIC) may display a message regarding the power top. See DIC Warnings and Messages on page 3-56 for more information. If the battery has been disconnected, the power windows must be initialized for the power top to operate. See Power Windows on page 2-17 for more information. 2.
