Controls in detail Retractable hardtop Opening and closing the retractable hardtop For safety reasons, the retractable hardtop can only be opened and closed when the vehicle is standing still. Warning! Shortly before the retractable hardtop is lowered, a warning will sound and in the left multifunction display you will see K, in the right multifunction display you will see the message Retractable Roof Lowering. Lock the retractable hardtop again before driving any further ( page 207). Otherwise, the unlocked hardtop could open while the vehicle is in motion and cause you to lose control of the vehicle. You or others could be injured as a result. Warning! G G Before operating the retractable hardtop, make sure there is no danger of anyone being injured by the moving parts (retractable roof, roof frame, and trunk lid) due to inattention. Hands must never be placed near the roof frame, upper windshield area, hardtop, shelf behind roll bars, or trunk lid while the retractable hardtop is being raised or lowered. Serious personal injury may occur. If potential danger exists, release the retractable hardtop switch. This immediately interrupts the raising or lowering procedure. You then can operate the retractable hardtop switch or press button Œ or ‹ on the SmartKey or SmartKey with KEYLESS-GO* to raise or lower the retractable hardtop away from the danger zone. To prevent possible accidents, only drive the vehicle with the retractable hardtop either completely closed and locked, or fully lowered into its storage compartment. If the retractable hardtop does not completely open or close, the roof hydraulics will lose pressure and the retractable hardtop is lowered after approximately 7 minutes when the ignition is switched on after approximately 15 seconds when the ignition is switched off 204
