Remember the Blindzone Glare Elimination (BGE) Setting

• The BGE setting requires turning the field of view of each outside mirror outward by about 15 degrees from the blindzone setting.
• For the driver's side mirror, this can be done by placing your head against the side window as shown in the image above and then setting the mirror to just see the side of the car.
• Do the same with the passenger's side mirror, but position your head at the middle of the car. You should next check to see that the blindzones are truly eliminated.
• From the normal diving position, watch a car as it passes you. It should appear in the outside mirror before it leaves the inside mirror, and it should appear in your peripheral vision before leaving the outside mirror. This is your proof that the blindzones have been eliminated and that your mirrors are correctly set.
• When changing lanes with BGE Setting, you must first look in the inside mirror for vehicles approaching from the rear; then glance at the outside mirror to see if a vehicle is in the blindzone.
• A good rule to follow when changing lanes is that if you can see the entire front of a vehicle in the inside mirror, and that vehicle is not gaining on you, it is safe to change lanes provided there is no vehicle in the blindzone.
• This is similar to the rule used when passing which says wait until you see the front of the car you just passed before changing lanes.
