How do I know when I can go back online?

Once you reach the limit of 13-hours online, you will be automatically placed offline. You can track the start and finish time via the red banner in the DiDi Driver App. 

How is the refresh time calculated if I go online and offline at irregular times? 

Your online time commences when you tap START in the DiDi Driver app and ends when you go offline.

For example, if you are online for two (2) hours and offline for four (4) hours, your online time will continue accumulating from the previous record of two (2) hours. To reset your online time, you must go offline for 8 consecutive hours to rest.
