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 be provided for several seconds to remind people to buckle their safety belts. The driver safety belt light will also be provided and stay on for several seconds, then it will flash for several more. You should buckle your seat belt. This chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. Notice: If you operate the engine with the tachometer in the shaded warning area, your vehicle could be damaged, and the damages would not be covered by your warranty. Do not operate the engine with the tachometer in the shaded warning area. If the driver's belt is buckled, neither the chime nor the light will be provided. 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. 3-36
