I would not. If you use the wrong fluid, then you destroy all the rubber seals related to the brake system. Most cases, it takes dot 4, 5 or synthetic.
Do not add any other fluid till you find the correct needed. It may say it on the top of the cap of the master cylinder.
Fluid Type MB Brake Fluid (DOT 4+) this is what alldata suggests
