Hummer 2009 H2 - Manual (Page 139)

Notice: The spare tire extends farther away from
rear of the vehicle than the trailer hitch shown on rear
vision camera display. The spare tire could hit an
object even though there appears to be enough
distance on the display between the trailer hitch
and objects behind you causing vehicle or property
damage. Do not use this system to judge the distance
between the spare tire and objects behind you.
When the System Does Not Seem To
Work Properly
The rear vision camera system might not work properly
or display a clear image if:
• The RVC is turned off. See “Turning the Rear
Camera System On or Off” earlier in this section.
• It is dark.
• The sun or the beam of headlights is shining
directly into the camera lens.
• Ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
• The back of the vehicle is in an accident, the
position and mounting angle of the camera
can change or the camera can be affected.
Be sure to have the camera and its position and
mounting angle checked at your dealer/retailer.
• There are extreme temperature changes.
