9-14 Vehicle Care Change the fluid and filter at the intervals listed in Scheduled Maintenance on page 10‑3, and be sure to use the fluid listed in Recommended Fluids and Lubricants on page 10‑7. Hydraulic Clutch It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. Refer to the Maintenance Schedule for the proper fluid to use. See Recommended Fluids and Lubricants on page 10‑7. The fluid requires changing every two years. See Scheduled Maintenance on page 10‑3. Manual Transmission Fluid It is not necessary to check the manual transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to a dealer/ retailer for service. Have it repaired as soon as possible. You may also have the fluid level checked by your dealer/retailer when the oil is changed. See Recommended Fluids and Lubricants on page 10‑7 for the proper fluid to use. How to Check and Add Fluid Visually check the clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The hydraulic clutch fluid system should be closed and sealed. Do not remove the cap to check the fluid level or to top-off the fluid level. Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line. When to Check and What to Use The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview on page 9‑6 for reservoir location.
