Starting & Stopping the Engine

Stalled Engine

You can restart the engine while the vehicle is stopped by squeezing the
front brake lever and pressing the start button.
Do not press the throttle lever while starting in gear. Your ATV is
equipped with a start inhibitor system that will cut off the ignition if the
throttle is open while attempting to start in gear.
Once you have started the engine, release the front brake lever, then
apply throttle gradually.
