1. Override switch "OVERRIDE" EBU13781 Override switch "OVERRIDE" Top speed is normally limited when operating in 4WD-LOCK. If conditions require more engine power when riding forward, push and hold this switch to override the 4WD-LOCK speed limiting function. (See page 4-11 for a detailed explanation about the differential gear lock switch and its function.) Releasing the switch restores the speed limiting function. While this switch is pushed, the segments of the speedometer digits will appear as shown in the figure. NOTE: If the digits of the speedometer appear as shown when the switch is NOT being pushed, this could indicate a malfunction in the electrical system. In this case, take the ATV to a Yamaha dealer at the first opportunity. _ _ 4-8
