This is an easy fix.
When the GDS screen loads up, choose the "Replacement" option under the "Repair" heading (4th along), enter your vehicle details and choose your engine and then click ok and you will then see at the bottom a tab called "Manual" (the first tab on the bottom left) that you can now click. This will then bring up the workshop manual for the vehicle you have selected, you can also change the selected vehicle by using the drop downs at the top.
