Repair Procedure
Diagnosis
NOTE
As with any new vehicle, a small amount of fogging may occur as a normal condition of off-gassing of
interior components AFTER production. This condition will dissipate over time and is NOT considered
abnormal. In these instances, regular cleaning, as part of normal vehicle care, is all that is necessary to
manage the condition.
This bulletin is ONLY applicable in cases where the level of fog, due to off-gassing, is abnormally
high within approximately one week AFTER the vehicle glass has been cleaned.
