How do I turn on my ITM transponder? 
• Mercedes instructions
I enrolled. When can I start using toll roads? 
It takes about 48 hours for your enrollment to reach the tolling authorities we work with. Until 
then, use your existing transponder or pay cash. If you opted into SMS, we will text you when your 
account is ready for use. 
I already have transponders. What should I do? 
Cancel or update any existing accounts with tolling authorities and return any transponders. If you 
have other vehicles on the account, you can keep the account open, but be sure to remove your 
ITM-equipped vehicle. This will prevent double billing or other potential issues related to having a 
single vehicle on multiple accounts. 
How do I know that the transponder is working? 
Toll is posted to Payviam overnight from the toll authority, the best way to know that the device 
is working is to log into my.payviam.com the day after you drove on a toll road and navigate to 
Usage. There you can see the most recent tolls. In some cases, the toll will appear 48 hours after it 
was incurred. 
I selected single zone coverage. How will my preferred zone be selected? 
If single zone coverage was available to you upon enrollment (only available on Audi) you can 
travel in any region for seven days after activation. Upon completion of this grace period, you will 
be automatically enrolled within the rst zone in which toll is captured. If you would like to select 
or change your preferred zone, please contact Payviam customer service at 1-888-725-1012 
or support@payviam.com.
