First of all, if you are not comfortable with any of this, then don't do it. It's not rocket science but it does require some little understanding.

You can actually remove the steering wheel and turn it by one spline. But that may leave leave the wheel askew in the other direction. Still, this is the best place to start.

Some will warn against this but you can minutely adjust this via the tie rods. Paul was on the right track but you should not disconnect the rod ends. You need to loosen the lock nuts.

This is done with wheels on the ground, pointed straight ahead and the steering column unlocked. You want the steering wheel to move, not the road wheels.

It takes some figuring to be sure which way to go. Turn both rods in the same direction by the same distance. Otherwise you'll mess up the toe adjustment. Keep track of your progress. You may find you have turned the steering wheel further away from where you want it and have to back track.

I wouldn't go more than a half turn of the rods at a time, first one side, then the other, repeating as needed. If the wheel is really only slightly off it shouldn't take much.

I reiterate: If you are not comfortable with the thought of doing this, then don't.

If you do undertake this procedure don't forget to tighten those lock nuts.

Also, Bruce Young, who posts here as "lucid" has pointed out that Volvo warns, "Steering rods must not differ more than 2 mm in length.
Measure between wrench grip and lock nut."

If none of this makes sense, don't undertake the procedure until it does.
