If you reference a warranty that has a limitation, it is sufficient to reference it on the ad.

It is false that referencing a warranty with a limitation on an ad is sufficient. While an ad can mention a warranty, any significant limitations or conditions must be clearly and conspicuously disclosed directly within the advertisement itself, or through a prominent link or other mechanism that immediately directs the consumer to the full terms. Simply referencing the existence of a warranty with a limitation without disclosing those limitations within the ad can be considered deceptive advertising. Consumers need to be able to understand the material terms of an offer without having to seek out additional information.
