WARNING:
- To prevent burns, do not touch the engine, exhaust pipe or other high temperature components while the engine is hot.
- Because the continuously variable transaxle assembly is extremely heavy, make sure to follow the work procedures described in the repair information.
*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:
- 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 Audio and Visual System (for Gasoline Model))
- After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System)
