Notice: If you operate the convertible top switch continuously while the ignition is in ACCESSORY, the battery will drain and you might not be able to start your vehicle. Do not use the convertible top switch for extended periods of time when the ignition is in ACCESSORY.

The ignition must be in RUN or ACCESSORY, your foot must be on the brake, and the vehicle must be stopped in order to raise the convertible top.

(Top Closed): Press and hold this symbol on the convertible top switch located on the center console switchbank to close the convertible top. Two chimes will sound when the top is fully closed.

A "Roof Cycle Timeout" message will display on the Driver Information Center (DIC) and the convertible top will stop moving when the programmed time limit is exceeded for the raised position. See "Roof Cycle Timeout" under DIC Warnings and Messages .

If the convertible top cannot be raised by using the convertible top switch, the fuse may need to be replaced. See Fuses and Circuit Breakers for more information.

If the convertible top still cannot be lowered or raised, contact your GM dealer.
