First this vehicle isn't offered in the US, so my technical information is very limited. However, I will try my best to help.
Have you checked the transmission fluid level and condition? Also, is the check engine light staying on while the engine is running?
If the fluid is low, that can cause problems. Also, if the check engine light is on, you really should have computer scanned for diagnostic trouble codes. Here is a quick video showing how it is done:
I realize most people don't own a scanner, but often times a parts store will do it free of charge or lend/rent a scanner.
Let me know what you find or if you have other questions.
