Curb View Assist Feature Listeded On Window Label - keywords dic glass mirror missing option reverse tilt

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some early built 2007 new style GMC Sierra's equipped with DL3 (Power, heated Outside Rear View mirrors) and A95 (high bucket reclining) front seats may have inaccurate information on the window label that indicates the OSRV mirrors have the "curb tilt" feature when, in fact, they do not have curb assist/tilt.

For vehicles in Dealer inventory, revised window stickers have been sent to affected GMC dealers. For sold units, we do not recommend any reprogramming/re-flashing changes be made to add the curb assist feature as software has not been validated and other adverse conditions may result.

Note: Estimate of sold units is less than 350 GMC Sierra's

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
