Unfortunately we don't have a manual on your vehicle because it is not offered in the USA so they don't include it in our manuals. However, in general the VVT solenoids are located at the camshafts as this is what controls the variable timing. So if you can locate your camshafts (assuming it is over head cam and there are multiple camshafts) they will be attached to the front or back of the cam itself.
Sorry I can't provide more detail then this.
Here is a guide that talks about this as well:
