The invention relates to the actuation of an openable roof system, for example of a cabriolet canopy system, in which a synchronized adjusting phase (Ts) is provided during the adjustment (t&#x3b8; to t) for opening and/or closing the vehicle roof system, in which synchronized adjusting phase (Ts) a first hydraulic actuator and a second hydraulic actuator are hydraulically coupled for the synchronized movement (s, s) of two components of the vehicle roof system. In order to increase operational reliability, in particular to reduce the risk of undesired collisions of the components, the invention provides monitoring of the synchronized movement (s, s) of the two components during the synchronized adjusting phase (Ts), and in the event of a deviation of the synchronized movement (s, s) from a predefined nominal synchronized movement being detected, correction of the synchronized movement by at least partially suspending the hydraulic coupling of the two hydraulic actuators.
