 ### **How Cooldown Works**
 
-* When Dependabot runs updates as per defined schedule, it checks the **cooldown settings** to determine if new release for dependency is still within its cooldown period.  
+* When {% data variables.product.prodname_dependabot %} runs updates as per defined schedule, it checks the **cooldown settings** to determine if new release for dependency is still within its cooldown period.  
 * If new version release date is within the cooldown period, dependency version update is **filtered out** and will not be updated until the cooldown period expires.  
 * Once the cooldown period ends for new version, the dependency update proceeds based on the standard update strategy defined in `dependabot.yml`.
