Abs light on, how do I fill reservoir

The brake fluid reservoir is part of the brake master cylinder. It is located on the drivers side of the engine bay at the back on the firewall. The reservoir will have markings on it as to the maximum fill level. DO NOT overfill the reservoir. Also, the ABS light being on is generally not an indication of low brake fluid. It usually indicates an electronic fault in the ABS system. Possible causes of this include a bad wheel speed sensor, bad brake light switch, and faulty ABS control module. With the ABS warning light on, the brakes will function as normal brakes, however the anti-lock function may not function at all. Your wheels can lock up under hard braking, especially on slippery surfaces. Have a certified technician inspect your abs system as soon as possible.
