The panel could fall into the vehicle and cause you to lose control, or it could fly off and strike another vehicle. You or others could be injured. Remove the roof panel only when the vehicle is parked. Sun Visors Pull the visor toward you, or move it to the side to help reduce glare. To use the lighted mirror, lift the cover.
