clutch automatically. With the car in gear but stationary, the clutch was released only when the throttle was applied. If neither brake nor gas pedal was depressed, a warning tone sounded and a message flashed on the on-board display, and if no action was taken after 7 seconds, the engine was shut off. Printed in error, a "Hill Start" function for Sensonic-equipped cars (as described in the owner's manual under "Rolling") was intended to assist in getting underway on hills to prevent rolling forwards or backwards. However, this feature was not implemented on any production unit. The 'Sensonic' clutch ceased production when the 900 model was replaced in 1998. Saab Information Display The NG900 introduced the Saab Information Display, or SID (available on S or SE models only), which gave the driver real-time information while driving, such as fuel efficiency and outside temperature. Base specification cars had a digital clock in place of the SID and a non-digital instrument panel with a mechanical odometer (as opposed to the digital odometer on higher-spec models). The SID also controls other vehicle components, including but not limited to audible warnings for turn signals and the vehicle's horn. NG engines 2.0 L B204I normally aspirated 16-valve four cylinder, 2.0 L B206I normally aspirated 16-valve four cylinder with no balance shafts, 2.0 L B204L 16-valve turbo intercooled, 2.3 L B234I naturally aspirated 16-valve four cylinder, 2.5 L B258I 24-valve 54º V6, Night Panel One Saab innovation, inspired by the company's roots in aeronautics, was the 'Black Panel' feature available in classic models through the turn of the panel dimming knob, and subsequently available (on S or SE models only), through the touch of a button on the SID (Saab Information Display) digital panel (classics had analog display), which extinguished most instrument panel lights, to eliminate distraction from dash lights during night driving. While active, the SID activated feature permitted darkened instruments to re-illuminate themselves when they required driver attention — if for example, the engine speed increased alarmingly or if the fuel level should drop below . This feature was later renamed 'Night Panel' in Saab 9-3 and Saab 9-5 models. In the later Night Panel version, the speedometer is only illuminated up to the 87 mph/140 km/h mark. The remainder of the scale will only be illuminated if the speed of the car exceeds 84 mph/135 km/h. 900i Under General Motors, Saab was repositioned
