Need advice on settlement offer for bodily injury from auto accident?

I received a check and release form from the at-fault driver's insurance company. I want to accept the check, as I do not forsee future medical costs ociated with the accident. HOWEVER, the wording/language of the release seems vague/too broad...it mentions a "full release" and mentions property damage. The vehicle is currently being repaired at a body shop and they have me in a rental car. If I sign this release, will they stop work on the vehicle and so forth? My only concern here is that I get my vehicle body repairs completed...I do not want to do anything to jeopardize that or release them from that particular part of the claim. Has anyone received offers like this before and signed them? What were the results? I may meet with an attorney and pay for 30 minutes of consultation time to have the doent reviewed, just to be safe...and/or write on the release that I am not releasing them from the obligation to repair my vehicle. Any advice on this? Other recommendations?
