How do you add fluid to clutch reservoir on 2002 Toyota Echo?

To add fluid to the clutch reservoir on a 2002 Toyota Echo, first locate the reservoir, which is typically near the back of the engine compartment, near the driver's side. Remove the cap from the reservoir and check the fluid level; if it's low, use DOT 3 or DOT 4 brake fluid, as recommended. Carefully pour the fluid until it reaches the appropriate level, then securely replace the cap. Be cautious not to spill any fluid, as it can damage paint and other surfaces.
