Hello. Battery saver mode comes into play when the electrical system voltage is too low. This mode shuts off "non-essential" components like the AC compressor in order to "get you to a safe place" before the battery is dead. There is likely something wrong with your charging system. Check the system voltage while the vehicle is running; it should be over 13 volts with a charging alternator and good voltage regulator.

I would recommend having a certified mechanic, such as one from YourMechanic, come to your location to complete an inspection to determine why the battery is acting unusually.
