A method and system for generating an alert to one or more occupants of a vehicle are provided. In one embodiment, the method includes receiving an input signal from a vehicle safety system. The input signal is indicative of an alert condition (e.g. an impending collision). The method further includes generating an output signal responsive to said input signal and wirelessly transmitting the output signal to the portable device. The portable device, such as a cellular communications device, has a haptic actuator and is configured to be mechanically disconnected from the vehicle while in physical contact with an occupant of the vehicle. The output signal, which may be transmitted directly to the portable device using short-range wireless communication protocols, is configured to activate the haptic actuator to cause a vibratory movement of the portable device and alert the vehicle occupant to the alert condition.
