Tachometer This gage indicates the engine speed in revolutions per minute (rpm). Safety Belt Reminder Light When the key is turned to ON or START, a chime will come on for several seconds to remind people to fasten their safety belts, unless the driver's safety belt is already buckled. The safety belt light will also come on and stay on for several seconds, then it will flash for several more. Engine Speed Limiter This feature prevents the engine from operating at too many revolutions per minute (rpm). When the engine's rpms are too high, the throttle is closed to reduce speed. If this is not sufficient, then the fuel supply to the engine will be limited. When the rpms return to normal, the fuel supply will return to normal. This helps prevent damage to the engine. If the driver's belt is already buckled, the chime will not come on. 3-36
