Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Remodelled cars feature interior effects including functional speedometers, fuel gauges and dashboard handbrake lights. The latter had room for oil pressure and tachometer gauges on models so equipped. The regulator has two pressure gauges, one indicating cylinder pressure, the other indicating hose pressure. The instrument panel used Optitron gauges and LED lighting. It also covers the specifications and dimensions for the thread gauges and measuring equipment. The instrument cluster was a combination of analogue gauges and screens. All cars received restyled, more modern instrument gauges. These were supplemented by mechanical pressure gauges. The oil, voltage and temperature gauges are now digital. NVH include microphones, accelerometers and force gauges, or load cells. Systems allow the adjustment between two gauges. Quality was thus precisely defined using devices such as plug gauges and ring gauges. It also featured retro themed gauges and a unique aluminum shifter ball. Also, they had minor complaints over the lack of water temperature and fuel gauges.
