WARNING
CAUTION
Do not attach a large key holder or key case to either key. If it banged against your knees or hands while you are driving, it could turn the ignition switch from the "ON" position to the "ACC" or "LOCK" position, thereby stopping the engine.
Also, if the key is attached to a key holder or to a large bunch of other keys, centrifugal force may act on it as the vehicle moves, resulting in unwanted turning of the ignition switch.

The ignition switch has four positions: LOCK, ACC, ON and START.
