Before driving your vehicle, check to see that your inside rearview mirror is properly positioned. Adjust the rearview mirror so that the view through the rear window is properly centered.
WARNING
Make sure your line of sight is not obstructed. Do not place objects in the rear seat, cargo area, or behind the rear headrests which could interfere with your vision through the rear window.
WARNING
To prevent serious injury during an accident or deployment of the air bag, do not modify the rearview mirror and do not install a wide mirror.
WARNING
NEVER adjust the mirror while driving. This may cause loss of vehicle control resulting in an accident.
NOTICE
When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.
