If you do not use your vehicle under any of these conditions, the fluid and filter do not require changing. Notice: For VTi variable transaxles, use only Saturn Variable Transaxle Fluid. Using any other fluid will result in transaxle damage. Damage cause by the use of fluid other than Saturn Variable Transaxle Fluid will not be covered by your warranty. Notice: For five-speed automatic transaxles, use only Saturn T-IV Transaxle Fluid. Using any other fluid will result in transaxle damage. Damage cause by the use of fluid other than Saturn T-IV Transaxle Fluid will not be covered by your warranty. Manual Transaxle Fluid It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your retailer's service department and have it repaired as soon as possible. You may also have your fluid level checked by your retailer or service center when you have your oil changed. See Recommended Fluids and Lubricants on page 6-14 for the proper fluid to use. Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. This system does not have its own reservoir. It receives fluid from the brake master cylinder reservoir. See Brakes on page 5-38 for more information. 5-25
