This vehicle is equipped with a sensor that detects when the brake fluid level is below the required minimum. The brake fluid level should be between the MAX line and the MIN line on the reservoir. The brake failure alarm indicator lamp (see Indicator Lamps) will illuminate if the brake fluid level falls below the minimum. On bumpy or rocky terrain, the lamp may also illuminate if the brake fluid level is close to the MIN line, but not below it. To avoid this, fill the reservoir up to the MAX line.
