Warning Lights and Gauges If the coolant continues to overheat, have the coolant system serviced as soon as possible. Engine coolant temperature gauge - mechanical cluster with tachometer Speedometer The speedometer tells you how many miles (kilometers) per hour your vehicle is moving. Some vehicles are equipped with a vehicle speed (mph/km/h) limiting device that is contained within the Powertrain Control Module (PCM). The purpose of this device is to maintain peak vehicle speed below a specified limit. (Vehicle speed limits may vary based on engine displacement.) If you are experiencing an "engine cut-out" condition at high speeds, it may be the result of this limiting device. It is a normal condition and can be avoided by reducing vehicle/engine speed. 93
