only us the GM coolant. they sell it at walmart. when you open the hood, its the clear tank in the upper right hand corner area. it will have a black cap as well

is that the same as what goes in the heat exchanger. the dxcool 50/50 mix

My low coolant light goes on about every startup,it eventually goes away once the car is warmed up.It started as the temp has dropped.

It should have Havoline's DEX-COOL in the car. You really don't want to mix anything other than that with it. While the any type, any brand/color coolant you can buy works okay in many cooling systems, it will degrade the effectiveness of the additive package and service life of the DEX-COOL.

Given that your car is at least a couple years old now, you might also want to consider flushing on refilling the entire system (and even just a regular drain and refill should be fine). While it may be advertised as a 5-year/150k mile coolant, it can form a sludge-o-death much sooner than that when other coolants or contaminants have been introduced and you really should change it out ever couple years for the best and longest service life.

Also make sure when you're topping the car up to only use distilled water. Don't use tap water as the coolant will have to use a big chunk of its additives to neutralize the minerals in the water and it will also leave more deposits in the cooling system. You can buy it in gallon jugs at most grocery stores.
