1. A vehicle comprising:
a plurality of auxiliary tanks configured to store liquid;
a first detection unit configured to detect a user activity associated with the plurality of auxiliary tanks;
a second detection unit configured to measure a weight in the vehicle;
a user interface;
a control unit communicatively coupled to the first detection unit, the second detection unit, and the user interface, wherein the control unit is configured to:
determine, using the first detection unit, that the user is proximate to a first auxiliary tank of the plurality of auxiliary tanks;
activate, based on the user being proximate to the first auxiliary tank, the second detection unit;
determine, based on the first auxiliary tank, a liquid type associated with the first auxiliary tank;
determine, using the second detection unit, a current weight in the vehicle;
determine a weight change in the vehicle based on the current weight and a baseline weight in the vehicle;
calculate a liquid level change associated with the first auxiliary tank based on the weight change and a density associated with the liquid; and
display, via the user interface, the liquid level change and the type of liquid.
