WARNING POTENTIAL HAZARD Riding too fast while the ATV is in 4WD-LOCK. WHAT CAN HAPPEN All wheels turn at the same speed when the differential is locked, so it takes more effort to turn the ATV. The amount of effort is more the faster you go. You may lose control and have an accident if you cannot make a sharp enough turn for the speed you are traveling. HOW TO AVOID THE HAZARD Always ride at a slow speed when the ATV is in 4WD-LOCK, and allow extra time and distance for maneuvers. NOTE: G When the switch is set to "LOCK", the differential gear lock indicator light will flash until the differential gear is locked. G When the indicator light is flashing, turning the handlebar back and forth will help the differential gear lock to engage. G Riding before the differential gear lock is properly engaged (e.g., when the indicator light is flashing) will cause the engine speed to be limited until engagement is complete. G When the ATV is in 4WD-LOCK, the maximum traveling speed is limited to 35 km/h (22 mph). However, if conditions require full engine power to be available, push and hold the override switch to disable the 4WD-LOCK speed limiter. (See page 4-8 for a detailed explanation of this switch.) _ _ 4-12
