When you want to use your Uber Cash balance, check to ensure it's turned on. To do this:
1. Enter your destination.
2. Before confirming your ride request, tap on your current payment method.
3. Make sure Uber Cash is turned on.
4. If you have a profile set up, select your payment method again to confirm Uber Cash is enabled.
5. Return to the previous screen and request your ride.
Your balance will automatically be applied on trips, unless you are using a business profile. If you want to use your Uber Cash balance with a business profile, you will need to manually enable Uber Cash before requesting.
When you don't have enough Uber Cash to cover a trip, the remaining cost will be charged to the primary payment method on your account.
