Maintenance and care 2. Visually inspect the fluid level. 3. If necessary, add brake fluid until the level reaches MAX. Do not fill MAX above this line. 4. Use only a DOT 3 brake fluid certified to meet Ford specifications. Refer to Lubricant specifications in the Capacities and specifications chapter. Brake fluid is toxic. If you use a brake fluid that is not DOT 3, you will cause permanent damage to your brakes. Do not let the reservoir for the master cylinder run dry. This may cause the brakes to fail.

Use only a DOT 3 brake fluid designed to meet Ford specifications. Refer to Capacities and specifications. For vehicles equipped with the 5-speed manual transmission, during normal operation, the fluid level in the clutch reservoir should remain constant. If the fluid level drops, maintain the fluid level at the step in the reservoir. For vehicles equipped with the 6-speed manual transmission, during normal operation, the fluid level in the clutch reservoir will drop slightly. As this occurs, maintain the fluid level at the step in the reservoir. 176
