Auxiliary batteries vary in size and specification dependent on the demands placed on it by the vehicle electrical system and can be used as a safety back-up to support the main battery when required or to provide voltage for specific vehicle systems all of the time.
Auxiliary battery is responsible for running and powering additional accessories in the car such as stop go function and many other, once it detects failure none of these functions will work.
Can I drive the car with the auxiliary warning on? While the vehicle can still be driven with an auxiliary battery warning light on, for safety reasons, we recommend getting this problem fixed as soon as possible.

Some Mercedes models have two batteries, a main starting battery located in the trunk and a secondary smaller battery located under the hood near the windshield on the passenger side of the car. Essentially there is so much electrical demand on this car it needs two batteries.
You can easily use your alternator to charge your second (auxiliary) battery simply by connecting the positive terminals of both batteries so that they’re in parallel.
The price for a new battery on a Mercedes-Benz will generally range from $280 to $400. However, you can cut the cost of battery replacement by as much as $100 and sometimes even $200 if you opt to do the replacement work yourself.
Luckily, if your auxiliary battery goes bad, your vehicle will not stop running but, you will notice that some of the main electrical components that the alternator cannot charge will not work.
other accessories continue to draw power when the engine is off. … However, simply wiring extra batteries into a vehicle’s electrical system can allow auxiliary batteries to drain power from the main battery, inhibiting engine starting and other essential functions.
For the hybrid vehicle battery, charge the battery at least once every two months by starting the hybrid system for about 30 minutes*. Check that the “ready” light is on and all lights and electrical accessories are off.
