Because the manual transaxle assembly is extremely heavy, make sure to follow the work procedures described in the repair manual.
*a
|
Heavy object exceeding the capacity of the transmission jack
|
-
If work is not performed according to the procedures described in the repair manual, there is a danger that the transmission jack could drop and components could fall down.
NOTICE:
-
After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System and Audio and Visual System (for Gasoline Model))
-
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.
