*a	Heavy object exceeding the capacity of the transmission jack

If work is not performed according to the procedures described in the repair information, there is a danger that the transmission jack could drop and components could fall down.

NOTE:

When the manual transaxle assembly is removed, be sure to use a new clutch release cylinder with bearing assembly and new installation bolts. Removal of the manual transaxle assembly allows the compressed clutch release cylinder with bearing assembly to return to its original position. Dust from the moving section may damage the seal of the clutch release cylinder with bearing assembly, possibly causing clutch fluid leaks.

HINT:

When the cable is disconnected / reconnected to the battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.
