The brake fluid reservoir is located under the hood on the passenger side toward the firewall. it should be white with a black cap that may say "brake". Unscrew this cap and look inside the reservoir for your fluid level, then check the side of the reservoir for fluid level markings. If your fluid level lines up with the mark that says "Full" - You are good to go. If not, and you are low, you will need to add DOT3 approved brake fluid until the level in the reservoir matches the full mark on the side of the reservoir.
One thing you may notice on the reservoir cap (underneath) is a rubber grommet "cup" which may be in the extended position...coming out of the cap. Gently push this back into the cap and screw back on to the reservoir.
Since your question indicates you may be a novice at this I want to add the brake fluid will (eventually) remove/damage your paint, so it is important to clean up any spills with soap and water as soon as possible.
